Bales of straw or hay when used as ditch checks or diversions around inlets or on slopes shall be placed on edge, fibers vertical and twine horizontal, and either cut into the soil 3" or bermed on the upstream side with 3" of earth fill. Each bale shall be anchored with 2-2"X 2" wooden stakes driven through the bale and at least 1 0" into the ground. Sod shall be maintained by the Contractor for at least 30 growing days prior to final inspection and acceptance. A "growing day" is defined as any calendar day exclusive to those days from June 10 to August 10 and from November 1 to May 5. During the maintenance period, all sod which dries out, is damaged, or displaced, or infected with weeds, shall promptly be replaced with new sod and maintained for at least 30 growing days after replacement. Seeding shall be inspected for acceptance at least 30 growing days after acceptable planting. Areas with no sign of or insufficient growth as determined by the Engineer, shall be reseeded and remulched by the Contractor at his own expense. Dormant seeding may be allowed in certain cases with special written permission of the Engineer. 02575.2 - MATERIALS: Seed shall be Mixture 250 applied at a rate of 70 pounds per acre. Fertilizer shall be applied at a rate of 200# of 24-12-24 per acre. Mulch shall be Type 1 with disc anchoring. Any imported topsoil that is to be used shall be tested to insure suitability. If in the Engineer's opinion the topsoil proposed is unacceptable, another source must be found. Topsoil shall be salvaged, stripping or borrow topsoil from on-site sources shall be considered incidental to seeding. The Contractor shall use Topsoil Borrow MnDOT Specification 3877, from an off-site source only after topsoil from on-site sources are expended. Topsoil salvage or borrowed from properties adjacent to the project shall be considered on-site sources. Topsoil shall be placed to a 6" depth on all areas to receive seed. Sod shall be lawn and boulevard type and installed in accordance with MnDOT.

The trench shall be so braced and drained that the workmen may work therein safely and efficiently. All trenches shall be sheeted and braced as per Chapter 66: Trench bracing of the Minnesota Regulations Relating to Industrial Safety to a safe angle of repose. Such angle of repose shall be no less than the repose required by the Accident Prevention Division of the Minnesota State Industrial Commission or the requirements of the Occupational Safety and Health Act (OSHA), whichever is more restrictive. It is essential that the discharge of any required trench dewatering pumps be conducted to natural public drainage channels, drains or storm sewers. All trenches shall be excavated so that the pipe may be laid accurately to grade with a minimum of 7Yz feet of earth cover over the top of the water mains, unless otherwise noted on the drawings. All utility installations under existing "collector" roads or newly constructed (less than 5 years old) residential streets must be jacked or directional bored as appropriate. No open trenching will be allowed. 7.02 TRENCH WIDTH AND DESCRIPTION The trench width, at the top of the trench, may vary depending on the depth of the excavation and the nature of excavated material encountered. All trenches shall be constructed in strict accordance with requirements prescribed by the Occupational Safety and Health Act (OSHA). The trench width at pipe grade shall be ample to permit the proper laying and jointing of the pipe and fittings and for proper backfilling and compaction. The maximum width of trench at the top of the pipe shall be not greater than the outside diameter of the pipe plus four feet. The trench shall have a bottom conforming to the grade to which the pipe is to be laid. The pipe shall be laid upon sound soil, cut true and even so that the barrel of the pipe will have a bearing for its full length. If the excavation is inadvertently made below the bottom conforming to grade, it shall be backfilled with well tamped pit run sand or fine gravel or other material as approved by the engineer at no additional expense to the owner. Bell holes shall be dug at the ends of each length of pipe to permit proper jointing. Excavations for manholes and other structures shall have one foot minimum clearance on all sides. The trench shall be kept free from water until the joints have been completed. 7.03 PIPE BEDDING I I I I I I I I I I I I I I I I I I I When using ductile iron pipe and existing soil conditions are not acceptable for backfill and/or compaction in the pipe zone, pipe bedding and backfill shall be used as shown on standard plate #2201. Otherwise, backfill as shown on standard plate #2202 may be used. When using PVC pressure pipe bedding and backfill shall be accomplished as per Section 7.02 of the sanitary sewer specifications and standard detail plate #2203. 7.04 PIPE FOUNDATION IN POOR SOIL When the bottom at subgrade is soft and in the opinion of the engineer cannot adequately support the pipe, a further depth and/or width shall be excavated and refilled to pipe foundation grade with approved material and thoroughly compacted as shown on standard detail plate nos. 2203 and 2203A; or other approved means, such as piling, shall be adopted to assure a firm foundation for the pipe with extra compensation allowed the contractor as provided elsewhere in these specifications. The contractor shall furnish, drive, and place piling if ordered by the engineer. Piles shall be driven in exact position at locations determined by the engineer. The contractor at his own expense must replace piles not correctly positioned at the completion of driving. 7.05 PIPE CLEARANCE IN ROCK Large stones shall be removed to provide a clearance of at least twelve inches (12") below outside barrel of the pipe, valves, or fittings, and to a clear width of 12" on each side of all pipe and appurtenances for pipe 16" or less in diameter; for pipes larger than 16", a clearance of 18" below and clear width of 9" on each side of pipe shall be provided. Adequate clearance for properly jointing pipe laid in rock trenches shall be provided at bell holes. 7.06 BRACED AND SHEETED TRENCHES The contractor shall adequately brace and sheet excavations wherever necessary to prevent caving or damage to nearby property. The cost of this temporary sheeting and bracing, unless provided for otherwise, shall be considered as part of the excavation costs without additional compensation to the contractor. Trench sheeting shall remain in place until pipe has been laid, tested for defects and repaired if necessary, and the earth around it compacted to a depth of one foot over the top of the pipe. Sheeting, bracing, etc. placed in the "pipe zone" (that part of the trench below a distance of one foot [I '] above the top of the pipe) shall not be removed without the written permission or written order of the engineer; that sheeting thereby left in place shall be paid for at the unit price bid. Sheeting ordered left in place by the engineer in writing shall be paid for at the unit price bid. The contractor may also leave in place, at his own expense, to be embedded in the backfill of the trench any sheeting or bracing in addition to that ordered left in place by the engineer for the purpose of preventing injury or damage to persons, corporations, or property whether public or private, for which the contractor under the terms ofthis contract is liable. 7.07 PILING OF EXCAVATED MATERIAL 19 20 I I I I I I I I I I I I I I I I I I I All excavated material shall be piled in a manner that will not endanger the work and that will avoid obstructing sidewalks and driveways.

A minimun1 of 50% ofthe individual water and sewer service trenches shall be tested at elevations listed above. I I I I I I I I I I I I I I I I I I I SECTION 10.00 - TESTING AND DISINFECTING MAINS 10.01 PRESSURE TESTING All water main including fittings, valves, services and hydrants shall be tested in accordance with and shall meet the requirements set forth in American Water Works Association (A.W.W.A.) Specifications C600, latest revision. The contractor shall have the option of using an alternative testing procedure as identified below: After the pipe has been laid including fittings, valves, hydrants, and service and the line has been backfilled in accordance with these specifications, all newly laid pipe, or any valved section thereof, unless otherwise directed by the engineer, shall be subjected to a hydrostatic pressure of 150 pounds per square inch. The duration of each such test shall be two (2) hours. The allowable pressure drop shall not exceed one (1) PSI in the said two (2) hour period. Each valved section of pipe shall be slowly filled with water and the specified test pressure, measured at the lowest point of elevation, shall be applied by means of a pump connected to the pipe in a satisfactory manner. The pump, pipe connection, gauges and all necessary apparatus shall be furnished by the contractor. Gauges and measuring devices must meet with the approval of the engineer and the necessary pipe taps made as directed. Before applying the specified test pressure, all air shall be expelled from pipe. To accomplish this, taps shall be made, if necessary, at points of highest elevations, and afterward tightly plugged. Each valved section shall be subjected to the pressure test and, if required, the leakage test prescribed herein. Testing for the two hour duration shall be with hydrants closed, and valves on hydrant leads and dead end water lines open. Once this portion of the test is completed, the valve on the hydrant leads and dead end water lines shall be closed, and hydrants opened. The specified test pressure shall be applied, and the test repeated for 15 minutes to establish the condition of the hydrant lead valves. This shall apply to both the pressure and leakage test. When tying into existing water main system, the contractor shall be responsible for pressure testing from the point of starting the new water main and including all newly constructed pipe and valves. If the contractor elects to test the existing water main, the City will not be responsible for any testing costs if the existing water main is the cause of any failing tests. Any cracked .or defective pipes, fittings, valves or hydrants discovered in consequence of the pressure test shall be removed and replaced by the contractor with sound material in the manner provided and the shall be repeated until satisfactory to the engineer.

The tablets shall be attached to the top of the pipe with an adhesive of hot tar or "Permatex" No.2 gasket cement, or other approved material. When the installation has been completed, the main shall be filled (after a 48-hour notice and receiving permission from the City's Utility Superintendent or his assigned representative) with water at a velocity of less than one foot (1 ') per second. This water shall remain in the pipe for at least 24 hours. After the 24 hour retention period, the heavily chlorinated water shall be flushed from the main until the chlorine concentration in the water leaving the main is less than 1 ppm. Tests are required to determine chlorine residual at the end ofthe 24-hour retention period and after flushing to ascertain that the heavily cWorinated water has been removed from the pipeline. At the end of the 24-hour retention period, the main shall contain not less than 10 ppm cWorine prior to placing the main in service. The contractor shall contact the Chanhassen Utility Superintendent for collection and testing of water samples. The contractor shall notify the Utility Superintendent 48 hours in advance to request such operation. All costs associated with testing shall be the responsibility of the contractor.

The water (containing chlorine) shall be left in the pipe, being disinfected, for a minimum of twenty-four (24) hours. 10.03 ELECTRICAL CONDUCTNITY TEST Conductivity test shall be performed on all D.I.P. mains after they have been pressure tested and are full of water at normal operating pressure. A direct current of350 amps shall be passed through the line for five minutes. Current flow shall be measured continuously on a suitable ampmeter and shall remain steady without interruption or excessive fluctuation throughout the period. Insufficient I I I I I I I I I I I I I I I I I I I current or wide fluctuations of ammeter needle shall be evidence of defective conductivity which shall be isolated, corrected and retested. The connection for the conductivity shall be made either to a gate valve or to the hydrant barrel. COImections shall not be made to any operating mechanism of the hydrant. Acceptable equipment for the test shall be arc welding machines with adequate sized cables to cany the test current without voltage drop or overheating. Conductivity test shall be carried out in the presence of the engineer or his duly authorized agent. Caution shall be exercised at all times when working with electrical equipment and wires during the conductivity test. 10.04 TRACE WIRE TEST - PVC WATER MAIN The contractor shall perform a conductivity test on all trace wire prior to the acceptance of the water system. This test may be performed by either hiring an acceptable underground utility locating firm to physically locate the trace wire in the presence of a city representative or via low voltage circuit completed with the use of a suitable voltage source and meter to ensure continuity of the trace wire. In the event that a closed clamp circuit cannot be completed or difficulties with the locating or test arise, the cause shall be isolated and corrected. Thereafter, the section in which the defective test occurred shall be re-tested as a unit and shall meet the requirements. 29 30 I I I I I I I I I I I I I I I I I I I SECTION 11.00 - SURFACE RESTORATION, CLEANUP AND GUARANTEE 1l.01 RESTORATION OF SURFACE All surfaces disturbed during the construction period including adjacent streets used to access the site, whether caused by actual excavation, deposition of excavated material, or by the construction equipment, shall be returned to its original conditions or better.

I I I I I I I I I I I I I I I I I I I SECTION 10.00 - HOUSE CONNECTIONS, WYES 10.01 GENERAL As indicated on the plans and detail plates, six-inch (6") wyes shall be installed for building connections at such intervals as the size of the lots may demand. Where the depth of the trench exceeds sixteen (16') feet, the contractor shall use a riser, and shall be extended to a minimum of nine (9') feet below the surface at a point nine (9') feet behind the property line (see standard plate No. 2001), or as shown on the plan for the invert of sewer services. No Fernco fittings will be allowed. Sewer service material including pipe, wyes and fittings shall be SDR 26. The joints and bedding shall be made as previously specified. The tops of all risers and openings to wye and/or tee branches shall be capped by solventweld plug to prevent any water from entering the service until the connection is placed in service. 10.02 RECORD AND LOCATION OF SERVICE CONNECTIONS It shall be the duty of the contractor to keep an accurate record of service connections as to location, depth to top of riser, type of connection provided, etc. Location shall be made in respect to the nearest manhole center downgrade from the service. Curb stops shall be tied to definable landmarks such as manholes, catch basins, gate valves, hydrants and building comers. The length of ties shall be no longer than 100 feet between tie points. If a permanent structure is not available within the 100-foot length, a third tie point of not more than 150 feet shall be supplied. Property comers, trees, power poles, light poles, telephone or utility boxes are not acceptable ties. This record shall be turned over to the engineer for his records at time intervals specified by the engineer. At the end of all house connections, the contractor shall furnish and set a two-inch by two-inch (2"x2") wooden marker stake set vertically to two feet (2') above the ground surface. In areas of newly platted land where the houses have not yet been built on the lots serviced, the contractor shall furnish and set steel fence posts securely wired to the two-inch by two-inch (2"x2") and allowed to extend three feet (3') to four feet (4') above the ground surface. The two-inch by two-inch (2"x2") wooden marker stake shall extend from the invert of the service stub to two feet (2') above the ground surface. If the sanitary sewer service is accompanied by a water service in the same trench then the six foot (6') steel fence post may be deleted. 20 21 I I I I I I I I I I I I I I I I I I I SECTION 11.00 - SANITARY SEWER LEAKAGE TESTING 1l.01 GENERAL Disposition of abandoned facilities and reconnection of existing facilities shall be as provided for in the Plans, Specifications, and Special Provisions. 11.02 SANITARY SEWER LEAKAGE TESTING All sanitary sewer lines, including service connections, shall be substantially watertight and shall be tested for excessive leakage upon completion and before connections are made to the service by Others. Each test section of the sewer shall be subjected to exfiltration testing, either by hydrostatic or air test method as described below and at the Contractor's option. The requirements set forth for maximum leakage shall be met as a condition for acceptance of the sewer section represented by the test. If the ground water level is greater than three feet above the invert elevation of the upper manhole and the Engineer so approves, infiltration testing may be allowed in lieu of the exfiltration testing, in which case the allowable leakage shall be the same as would be allowed for the Hydrostatic Test. All testing shall be performed by the Contractor without any direct compensation being made therefore, and the Contractor shall furnish all necessary equipment and materials, including plugs and standpipes as required. 11.03 AIR TEST METHOD The sewer pipe section under test shall be clean at the time of testing but the pipe may be wetted. Pneumatic balls shall be used to plug the pipe ends at manholes. Low pressure air shall be introduced into the plugged line until the internal air pressure reaches 4.0 psi greater than the average back pressure of any ground water pressure that may submerge the pipe. At least two minutes shall be allowed for the air temperature to stabilize before readings are taken and the timing started. During this time the Contractor shall check all plugs with soap solution to detect plug leakage. If plugs are found to leak, air shall be bled off, the plugs shall be retightened, and the air shall be reintroduced into the line. The sewer section under test will be accepted as having passed the air leakage test if it does not lose air at a rate to cause the pressure to drop from 3.6 to 3.0 psi in less time than one-half minute per inch in diameter of the pipe tested. I I I I I I I I I I I I I I I I I I I Pipe Diameter in Inches Minutes 4 2.0 6 3.0 8 4.0 10 5.0 12 6.0 IS 7.5 18 9.0 21 10.5 11.04 HYDROSTATIC TEST METHOD After bulkheading the test section, the pipe shall be subjected to a hydrostatic pressure produced by a head of water at a depth of three feet above the invert elevation of the sewer at the manhole of the test section. In areas where ground water exists, this head of water shall be three feet above the existing water table. The water head shall be maintained for a period of one hour during which time it will be presumed that full absorption of the pipe body has taken place, and thereafter for an extended period of one hour the water head shall be maintained as the test period. During the one hour test period, the measured water loss within the test section, including service stubs, shall not exceed the Maximum Allowable Loss (in Gallons Per Hour per 100 Feet of Pipe) given below for the applicable Main Sewer Diameter. Main Sewer Diameter Maximum Allowable Loss* (In Inches) (In Gallons Per Hour Per 100 Feet) 6 0.5 8 0.6 10 0.8 12 1.0 15 1.2 18 1.4 21 1.7 24 & Larger 1.9 *Based on 100 Gallons Per Day Per Pipe Diameter Inch Per Mile 22 23 I I I I I I I I I I I I I I I I I I I If measurements indicate exfiItration within a test action section is not greater than the allowable maximum, the section will be accepted as passing the test. II.OS DEFLECTION TEST Deflection tests shall be performed on all plastic gravity sanitary sewer pipes. The test shall be conducted after the sewer trench has been backfilled to the desired finished grade and has been in place for 30 days. The deflection test shall be performed by pulling a rigid ball or pointed mandrel through the pipe without the aid of mechanical pulling devices. The ball or mandrel shall have a minimum diameter equal to 95% of the actual inside diameter of the pipe. The maximum allowable deflection shall not exceed five percent of the pipe's internal diameter. The time of the test, method of testing, and the equipment to be used for the test shall be subject to the approval of the City Engineer. The contractor shall check for excess deflection in all portions of the PVC sanitary sewer line after placement of the backfill materials in the trench. The deflection will be checked by means of a Mandrel prior to final acceptance of the sanitary sewer line or after 30 days of its installation, whichever is the greater. The owner reserves the right to measure pipe deflection at any time during the warranty period. Deflections greater than 5% of the inside diameter of the pipe shall be considered failure of the bedding procedure. The test shall be performed without using mechanical pulling devices. The contractor shall be required to re-excavate the trench, recompact the backfill material and restore the surface at no additional compensation with the re-Iaid pipe meeting the 5% requirement. An air pressure retest to be performed if applicable. All testing shall be performed by the Contractor at his expense without any direct compensation being made therefore, and he shall furnish all necessary equipment and materials required. 11.06 TEST FAILURE AND REMEDY In the event of test failure on any test section, testing shall be continued until all leakage has been detected and corrected to meet the requirements. All repair work shall be subject to approval of the Engineer. Introduction of sealant substances by means of the test water will not be pennitted. Unsatisfactory repairs or test results may result in an order to remove and replace pipe as the Engineer considers necessary for test confonnance. All repair and replacement work shall be at the Contractor's expense.

Depositing of the backfill shall be done so the shock of falling material will not injure the pipe or structures. Grading over and around all parts of the work shall be done as directed by the engineer. Bedding material as specified in Sewer Specification 7.02 or other suitable material as determined by the engineer, free from rocks and boulders, shall be deposited in the trench simultaneously on both sides of the pipe for the full width of the trench to a height above the top ofthe pipe as specified shovel placed and hand tamped to fill completely all spaces under and adjacent to the pipe. In the event that natural, suitable, granular material is not encountered during the normal excavation of the trench, or when the material encountered is determined unsuitable by the engineer, for backfilling around the pipe as required above; the contractor shall provide and place such approved material obtainable from other sources. (This procedure and specification is applicable to all sanitary sewer and storm sewer installations.) 13.03 BACKFILL PROCEDURE ABOVE THE PIPE ZONE Unless otherwise specified, suitable backfill material shall be furnished and the following backfill procedures shall apply and be used above the "pipe zone" to either the existing surface elevation or design grade, as specified, with the cost of such considered incidental to the installation of the pipe unless specified for a particular section of the project by the special provisions and/or plans, or allowed in writing by the engineer, and a unit price has been established. 13.03A Tvpe 1. The trench shall be backfilled to obtain the necessary compaction, with the lift thickness as required, dependent upon type of roller. The backfill material shall be compacted to 95% of the standard moisture density relationship of soils (ASTM D698-70) except the top three feet (3') of the trench which shall be compacted to 100% density. The moisture contents of these backfill materials shall be within a range of:f: 3% of optimum moisture content. If the existing moisture content of the backfill material below three feet of subgrade is greater than 3 percentage points above the optimum moisture content, the soil shall be compacted to a minimum density of 3 pounds per cubic feet less than the standard Proctor curve at that moisture content. At no time shall the density be less than 90 percent of the standard Proctor density. This modification ofthe compaction specification shall at no time be used or applied to the upper 3 feet of the subgrade or the aggregate base. In the event the contractor fails to meet these compaction requirements, corrective measures such as spreading/discing/farming, etc. shall be undertaken or the Contractor may elect to backfill with a more suitable material taken from another source. All of these corrective measures shall be at the Contractor's expense. 26 , . 27 I I I I I I I I I I I I I I I I I I I Any settlements greater than one inch (I If) as measured with a string line from one edge of the settlement to the other within the warranty period of this contract shall be considered fc'lilure of the mechanical compaction and all street surfaces, driveways, boulevard and ditch areas shall be repaired by the contractor at no cost to the City. 13.03B Type II.

The Owner will review the qualifications and experience of bidders after bids are opened and before a contract is awarded, to determine if the bidder is "responsible." A "responsible" bidder is a bidder qualified to do the work. This will be determined by assessing the bidder's skill, resources, experience, successful performance of similar contracts (on time and on budget), and all other matters bearing upon the likelihood that the contract will be successfully completed. In all cases where a bidder is unknown or where there are any questions about the qualifications of the bidder, the following information may be required of the apparent low bidder: 1. Identify all similar public projects in which you were the contractor. If you have had more than five such contracts, list only the last five contracts, and as to each contract identified, provide the following information: Project Description: Date: Contact Person at City/County/State: Were change orders in excess of 5% requested? If yes, explain the circumstances. Were liquidated damages assessed? If yes, explain the circumstances. Was the project completed on schedule? Ifno, explain the circumstances. 2. Describe all construction arbitration claims and any construction or project litigation in which you have been a party in the last five years. 3. Identify all public projects you have had with the City of Chanhassen in the last five years. 4. In the last five years, has a bonding company ever refused to issue you a performance bond? If yes, explain the circumstances. 5. In the last five years, have any claims been filed against a performance or G-5 G-G I I I I I I I I I I I I I I I I I I I payment bond that you have provided a public entity? If yes, explain the circumstances. 6. In the last five years, has your firm or any of its owners or employees been fined by a federal or state agency for a contract or workplace matter (such as wage or hour or safety violations), or debarred under Part 29, Title 49 CFR or any other law from submitting bids on public projects? If yes, explain the circumstances. 7. In the last five years, has your firm or any of its owners or employees been charged or convicted of a crime involving the awarding, bidding or performance of a government contract? If yes, provide full details. The bidder agrees that they are fully responsible to the Owner for the acts and omissions of any proposed subcontractors and of persons either directly or indirectly employed by them, as they are for the acts and omissions of persons directly employed by them. Failure on the part of any bidder to carry out previous contracts satisfactorily, or lack of experience or equipment necessary for the satisfactory completion of the project, may be deemed sufficient cause for disqualification. 2.02 CONTRACT DOCUMENT INTERPRETATIONS:' All applicable laws, ordinances, and the rules and regulations of all authorities having jurisdiction over construction ofthe project shall apply to the contract throughout, and the Contractor shall be responsible for familiarizing themselves with all permits, bond and other requirements for the work to be performed. All work shall be performed in accordance with the most recent version of the City of Chanhassen Standard Specifications and Detail Plates. In the event a work item is not addressed in the Chanhassen Standard Specifications and Detail Plates, the most recent version of the Minnesota Department of Transportation Standard Specifications shall govern. Whenever reference is made to the Minnesota Department of Transportation Standard Specifications, the word "Owner" shall be substituted for "State" and "Department" where appropriate and the word "Engineer" is understood to refer to the engineer for the Owner. The City ofChanhassen Standard Plates included as part of these Specifications take precedence over the Minnesota Department of Transportation Standard Plates in all instances of conflict. If any person contemplating the submitting of a bid for a proposed contract is in doubt as to the true meaning of any part of the plans, specifications or other proposed Contract Documents, they may submit to the Engineer a written request for an interpretation thereof at least three days prior to the scheduled bid opening. The persons submitting the request will be responsible for prompt delivery to the Engineer. Any interpretation of the proposed documents shall be made by addendum, duly numbered and dated. A copy of such addendum will be sent I I I I I I I I I 2.03 I I I 2.04 I I I I I 2.05 I I certified mail, return receipt requested, when there are five mail delivery days before the bid opening to each prospective bidder who had received a set of documents prior to the date of the addendum, and each bidder shall acknowledge receipt of that addendum on their proposal form. Addenda will not be mailed within five mail delivery days of the bid opening. Plan holders will be asked to pick up materials at the Engineer's office or when available, can receive the materials via facsimile. Such addendum will be attached to all documents issued after the date of the addendum and shall remain a part thereof. The Owner and Engineer will not be responsible for any other explanation or interpretation. The Owner reserves the right to modifY the plans, specifications, special provisions, or proposal at any time prior to bids being opened, in accordance with the procedures for issuance of an addendum. All proposals shall be made and received with the express understanding that the Bidder accepts the terms and conditions contained in these instructions and the plans and specifications, forms of contract and bond, and any other Contract Documents referred to herein. If, after the bids have been delivered to the Owner, any difference of opinion shall arise as to the true intent or meaning of any part of the specifications, the decision of the Engineer shall be final, conclusive, and binding on all parties. INTERPRETATION OF OUANTITIES IN BID SCHEDULE: The schedule of quantities is approximate only and is assumed solely for the purpose of comparing bids. The quantities on which payment will be made to the Contractor are to be determined by measurements of the work actually performed by the Contractor as specified in the Contract Documents. SITE INVESTIGATION: Each bidder must satisfY themselves and form their own opinions by personal examination of the location and ground of the proposed work, and by such other means as they may desire, as to the actual conditions and requirements of the work, including the materials to be excavated; must make their own interpretations and satisfY themselves by their own investigations and research regarding all conditions affecting the work to be done and the labor and materials needed, and shall make their sole reliance thereon. Any information or data furnished by the Owner or its representatives is for the convenience of any bidder and is not guaranteed. The bidder shall thoroughly examine and familiarize themselves with the Drawings, Special Provisions, and all other Contract Documents. The Contractor, by the execution of the contract, shall accept all responsibility for having examined the site and acquainted themselves with the conditions there existing and the conditions of the contract. The Owner will be justified in rejecting any claim based upon the contractor's lack of proper examination of the site conditions and legal obligations of the contract after execution ofthe contract. SUBMISSION OF PROPOSAL: Sealed bids will be received by the Owner up to the date and hour as specified in the Advertisement for Bids at the office of the G-7 G-8 I I I I I I I I I I I I I I I I I I I Owner or as otherwise specified. Bids received after the time specified shall be returned unopened. All bids must be in ink upon the bid form included in the Specifications with a given price for each item and aggregate amount for the work, and must be signed and acknowledged by the bidder in accordance with the directions on the bid form. If a separate proposal form is provided, this separate form is to be submitted, not the form bound into the specification book. In order to ensure consideration, the bid shall be enclosed in a sealed envelope addressed to the Owner and clearly marked as to the time and date of bid opening, the name of the project, and name and address of bidder. 2.06 PROPOSAL GUARANTY: Each bid shall be accompanied by a Proposal Guaranty in the form of a money order, certified check or bid bond, payable to the order of the owner in an amount not less than five percent (5%) of the total amount of the bid. No bid will be considered unless accompanied by the Proposal Guaranty. In case alternate bids are called for, one Proposal Guaranty in the amount of five percent (5%) of the total amount of the highest bid alternative will be sufficient for all bids. As soon as the bids have been tabulated, all Proposal Guarantees shall be returned to the bidders, except those of the three lowest responsible bidders, which shall be returned after the agreement is executed and the required bonds and insurance received, approved, and accepted by the Owner. 2.07 AFFIDAVIT OF NON-COLLUSION: Each bidder shall submit with his proposal, an affidavit of non-collusion, signed by one of the officers of the firm and notarized. The Affidavit to be used is bound into these Contract Documents. A sample affidavit is included in the attachments. 2.08 WITHDRAWAL OF PROPOSALS: Any bid may be withdrawn or modified prior to the schedule time for the opening of bids or authorized postponement thereof. After the time set for opening of the bids, no bidder may, without the consent of the Owner, withdraw their bid or claim extra compensation or damages for any error or omission made by said bidder in preparing their bid, for a period of 60 days. Bid guarantees may be held by the Owner for said 60 days until all of the bids submitted have been canvassed, a contract awarded and executed, and the required bonds and insurance furnished and approved. Should there be reasons why the contract cannot be awarded within the specified period, the time may be extended by mutual agreement between the Owner and the bidder. I I I I I I I I I I I I I I I I I I I SECTION 3.00 - AWARD AND EXECUTION OF CONTRACT 3.01 EY ALUATION OF PROPOSALS: The bids from each responsible bidder will be considered on the basis of the amounts as shown on the bid form, and awarded to the lowcst bidder determined by correctly adding the products resulting from correctly multiplying the quantities statcd by the unit prices bid therefore, and as otherwise described in the Spccial Provisions when alternate bids are included in the proposal form. The prices are to include the furnishing of all materials, all labor and services necessary or proper for the completion of work, except such as ~ay be otherwise expressly provided in the Contract Documents. The Owner reserves the right to reject any or all bids or to accept the bid deemed in the best interest of the Owner. Without limiting the generality of the foregoing, any bid which is incomplete, obscure, or irregular may be rejected; any bid having erasures or corrections in the price sheet may be rejected; any bid which omits an amount on anyone or more items in the price sheet may be rejected; any bid in which unit prices are obviously unbalanced may be rejected; any bid accompanied by an insufficient or irregular bid bond may be rejected; any bid which omits acknowledgment ofthe receipt of addenda may be rejected. The Owner may make such investigations as deemed necessary to determine the ability of the bidder to perform the work, and the bidder shall furnish to the Owner all such information and data for this purpose as the Owner may request. The Owner reserves the right to reject any bid if the evidence submitted by, or investigation of, such bidder fails to satisfy the Owner that such bidder is properly qualified to carry out the obligations of the Agreement and to complete the work contemplated therein. All bids shall be subject to review and approval of the Owner. 3.02 CONTRACT A WARD AND EXECUTION: Following acceptance of the bid by the Owner, a "Notice of Award" letter will be mailed to the Contractor together with the prepared contract agreements for signature and return. The Notice of Award letter will specify that the Contractor also submit affidavits or copies of insurance coverage, a payment bond and a performance bond. No contract will be executed until the required affidavits and bond are submitted and have been approved as to form by the Owner. The performance bond and payment bond shall each be in the amount of 1 00 percent of the contract price with a corporate surety approved by the Owner. Attomeys-in- fact who sign bid bonds or performance bonds must file with each bond a certified and effective dated copy of their power of attorney. For purposes of the agreement, affidavit of insurance, the payment bond, and performance bond, the contract amount is the bid amount accepted by the Owner. The final amount of the contract shall be determined by summation of multiplying and summing the resulting product of the final measured quantities of the various G-9 G-lO I I I I I I I I I I I I I I I I I I I items actually constructed and installed by the unit prices stated therefore, in the manner prescribed in the specification. The party to whom the contract is awarded will be required to execute the Agreement, obtain the affidavits, the payment bond, and the performance bond, and return them to the Engineer within 10 calendar days from the date when Notice of Award is delivered to the bidder. In case of failure of the bidder to complete these items, the Owner may at their option consider the bidder in default, in which case the bid guaranty accompanying the proposal shall become the property of the Owner. The Owner within 10 calendar days of receipt of acceptable performance and payment bonds, affidavits and Agreement signed by the bidder to whom the Agreement was awarded shall sign the Agreement and return to the bidder an executed duplicate of the Agreement. Should the Owner not execute the Agreement within such period, the bidder may by written notice withdraw their signed Agreement. Such notice of withdrawal shall be effective upon receipt of the notice by the Owner. A notice to proceed shall be issued within 10 calendar days of the execution of the Agreement by the Owner. Should there be reasons why the Notice to Proceed cannot be issued within such period, the time may be extended by mutual agreement between the Owner and Contractor. If the Notice to Proceed has not been issued within the 10 calendar day period or within the period mutually agreed upon, the Contractor may terminate the Agreement without further liability on the part of either party. The Notice of Award letter is not an order to proceed. The Contractor will have no authority to perform work under this contract until all Contract Documents as indicated above are properly completed and placed on file at the Owner's Offices and a Notice to Proceed is issued by the Owner. A Notice to Proceed with the work under this project will be sent to the Contractor upon satisfaction of the above-indicated requirements and after a preconstruction conference is held. 3.03 PROPOSAL ALTERNATES: When a project includes a bid alternate, all bidders are required to submit pricing for said alternate as a part of their bid. The Owner reserves the right to accept or reject any or all of the individual items included as a part of the bid alternate. The Owner-accepted bid alternate items' prices will be considered as part of the low bid determination for contract award. If all alternates are rejected, the lowest base bid submitted will be considered the low bid for purposes of contract award. 3.04 CONTRACT SECURITY & GUARANTY: The successful bidder shall be required to furnish the Owner with a performance bond and payment bond in the form required by law, each in an amount of one hundred (100%) percent of the contract amount, based on the lump sum or the anticipated quantities and unit prices, as determined by the Engineer. I I I I I I I I I I I I I I I I I I I 3.05 3.06 The bonds shall guarantee the proper prosecution and completion of the work by the successful bidder; and shall further guarantee the prompt payment by the successful bidder or all persons or firms furnishing labor, tools, materials and supplies for the work. Upon completion of said work, an acceptable and separate 100% maintenance bond shall be furnished to guarantee the quality of material and workmanship of said work for a period of two years from the date of final acceptance by the City. The Contractor may not release the surety company on this 100% maintenance bond until a written release of said 100% maintenance bond is given by the Owner. When a period of two years has elapsed after the date of the acceptance of the work by the Owner and if upon inspection by the Owner the work is found in good condition the maintenance bond shall be released. If it is found by the inspection after two years use that some ofthe work and some of the materials are defective, such work or materials shall be replaced or repaired by the Contractor, and only when the Contractor has properly replaced and repaired such defective work and/or materials will the Owner then release the 100% maintenance bond. In the event that the Contractor fails to meet the time obligations of the initial maintenance bond and requests an extension of time, a $1,000 escrow will be required to offset additional costs incurred by the Owner to administrate the maintenance bond extension. PRE-CONSTRUCTION CONFERENCE: Prior to the start of any work there shall be a pre-construction conference arranged by the Engineer. Representatives of the Owner, Engineer, Developer, Contractor, Subcontractor, Project Foreman, and Utility Companies shall be notified to be present at this meeting. The Contractor's project superintendent shall be familiar with all phases of the work to be executed and shall oversee the work during its progress. The project superintendent shall represent the Contractor, and communications and directions given to the superintendent shall be as binding as if given to the Contractor. The Contractor's list of subcontractors and suppliers shall be submitted and reviewed along with scheduling, materials (including bituminous mix design), material sources, proposed haul routes, construction methods, desired materials substitutions, and any other information necessary for the orderly execution of the work. FAILURE TO EXECUTE CONTRACT: Failure on the part of the successful bidder to execute the Contract, furnish an acceptable bond, or comply with any other requirements imposed precedent to the Contract, within the time allowed, shall be considered just cause for cancellation of the award and forfeiture of the Proposal Guaranty, not as a penalty, but in liquidation of damages sustained. Award may then be made to the next lowest responsible bidder, or the work may be re-advertised or otherwise performed at the discretion ofthe Owner. G-l I G-12 I I I I I I I I I I I I I I I I I I I SECTION 4.00 - SCOPE OF WORK 4.01 ADDITIONAL INSTRUCTIONS. If the instructions and plans are not sufficiently clear to permit the Contractor to proceed with the work, the Engineer shall, upon the request of the Contractor, furnish additional written instruction, together with additional drawings as may be necessary. When such request is made by the Contractor, it must be in ample time to permit the preparation ofthe instructions and drawings by the Engineer before the construction of the work covered by them is undertaken. Such additional instructions and drawings shall be consistent with the Contract Documents and shall have the same force and effect as if contained in the original Contract Documents. For the purpose of avoiding delays in the preparation of such additional instructions and. drawings, the Engineer and the Contractor shall jointly prepare a schedule showing the time for the commencement of the work to be included in them and the time the Contractor shall furnish the necessary shop drawings which may be necessary for their preparation. The Contractor shall do no work without proper drawings or instructions and shall replace any work not in accordance with such drawings and instructions at no additional cost. 4.02 CHANGES OR ALTERATIONS IN TIIE WORK: The Owner, without invalidating. the contract, may order extra work or make changes by altering, adding to or deducting from the work; the contract sum being adjusted according to the respective unit bid prices. All such work shall be executed under the conditions of the original contract, except that any claim for extension of time caused thereby shall be adjusted at the time of ordering such change. If the Contractor claims that any instructions by drawings or otherwise issued after . the date of the contract involved extra cost under the contract, the Engineer shall be given written notice thereof within seven days, after the receipt of such instructions, and in any event before proceeding to execute the work, except emergency endangering life or property, and the procedure shall then be as provided for elsewhere herein for changes in the work. No such claim shall be valid unless so made. In giving instructions, the Engineer shall have authority to make minor changes in the work, not involving extra cost, and not inconsistent with the purposes of the work but otherwise (except in an emergency endangering life or property) no extra work or change shall be made unless in pursuance of a written order by the Engineer. 4.03 ORAL AGREEMENTS: No oral order, objection, claim or notice by any party to the others shall affect or modify any of the tenns or obligations contained in any of the contract documents, and none of the provisions of the Contract Documents shall be held to be waived or modified by reason of any act whatsoever, other than by a definitely agreed waiver or modification thereof in writing, signed by the parties to be bound or by the representatives of the parties authorized to enter into such a waiver or modification, and no evidence shall be introduced in any proceeding of any other waiver or modification.

Every request for an interpretation shall be made in writing and addressed and forwarded to the Engineer. The Owner will not be responsible for any other explanation or interpretation of the plans and specifications. If unforeseen conditions require a change in the dimensions of a structure, location of underground pipes, or major variations of a similar nature from the original plans, necessitating exceeding the reasonable limits defined above, or being of the nature of a substantial departure from the original plans, such change shall be covered by a change order. The change order is to set forth in complete detail the nature of the change and reasons therefor. The compensation to be paid the Contractor and whether it is an addition or a reduction with respect to the original contract costs is also to be covered in detail. Should additional or supplemental drawings be required, they will be furnished by the Engineer. SALVAGE: Unless otherwise indicated on the plans or in the Special Provisions, all castings, pipe and any other material taken from the work shall be the property of the Contractor. FOSSILS: If any fossils, treasure or other unusual or valuable geological formations are found in the progress of excavating, such fossils, treasure or samples of geological formations shall be carefully preserved by the Contractor and the Contractor shall restrict or suspend operations in the immediate area of the discovery and shall immediately notifY the Engineer of the discovery. The suspension of work for a period not to exceed 72 hours shall be allowed without claim by the Contractor for any damages as a result thereof. These items shall become the property of the state or federal agency concerned with their preservation and study. CLEANUP: The Contractor shall, at no cost to the Owner, clean up and remove all refuse and unused materials of any kind resulting from the work. Upon failure to do so within 72 hours after request by the Engineer, the work may be done by the Owner and cost thereof be charged to the Contractor and deducted from the final estimate.

The Engineer shall, within a reasonable time after receiving written notification, make decisions in writing on all claims of the Owner or the Contractor and on all other matters relating to the execution and progress of the work or the interpretation of the Contract Documents. All such decisions of the Engineer shall be final, except where time or financial considerations are involved, in which case, the decision is subject to arbitration (if less than $10,000) as per these general conditions. Any dispute over $10,000 shall be settled in Carver County District Court. Failure to condemn any inferior material or work at the time of its use or construction shall not be construed as an acceptance of the same, but the Contractor shall upon notice from the Engineer at any time prior to the final acceptance of the improvement irrimediately tear out, remove and properly reconstruct, at no cost to the Owner, any portion of this improvement which the Engineer may decide to be defective and the Contractor will be held wholly responsible for the safety, proper construction and perfection of the entire improvement until the same has been finally accepted and paid for by the Owner. The Engineer will make final inspection of all work included in the contract or any portion thereof, as soon as practicable after notification by the Contractor that such work is nearing completion. If such work is not acceptable to the Engineer at the time of the inspection, the Contractor will be advised in writing as to the particular defects to be remedied before such work can be accepted. If, within a period of ten days after such notification, the Contractor has not taken steps to speedily complete the work as directed, the Engineer may, without further notice and without in any way impairing the contract, make such other arrangements as deemed necessary to I I I I I I I I I I I I I I I I I I I 5.02 5.03 5.04 5.05 5.06 5.07 i have such work completed in a satisfactory manner without regard to remaining contract completion time. The cost of completing such work shall be deducted from any moneys due, or which may become due the Contractor on the contract. INTENT OF PLANS AND SPECIFICA TrONS: The intent of the plans and specifications is that the Contractor furnish all labor and materials, equipment and transportation necessary for the proper execution of the work unless specifically noted otherwise. The Contractor shall do all the work shown on the plans and described in the specifications and all incidental work necessary to complete the project in an acceptable manner and to fully complete the work or project, ready for use, occupancy and operation of the Owner. It is further the intention of the plans and specifications to set forth requirements of performance, type of equipment and structures, and standards of materials and construction, to require new material and equipment unless otherwise indicated and to require complete performance of the work without specific reference to any minor component part. It is not intended, however, that materials or work not covered by the specifications shall be supplied unless distinctly so noted. Materials or work described in words, which so applied have a well known technical or trade meaning, shall be held to refer to such recognized standards. All work shall be completed in accordance with the specifications and plans, and in compliance with applicable laws of Federal, State and local governments. SHOP DRAWINGS: The Contractor shall, upon request, submit shop drawings in quadruplicate for the approval of the Engineer. DIMENSIONS: Figured dimensions on the plans will be used in preference to scaling the drawings. Where the work of the Contractor is affected by finish dimensions or manufacturer's equipment, these shall be determined by the Contractor at the site, and he shall assume the responsibility therefore. MODELS: All models prepared for this work, in accordance with requirements of plans and specifications, shall become the property ofthe Owner at the completion of the work. ADEQUACY OF PLANS AND SPECIFICATIONS: The complete requirements of the work to be performed under the contract shall be set forth in plans and specifications to be supplied by the Owner through the Engineer or by the Engineer as representative of the Owner. CONFLICT: In the case of a conflict of meaning between any of the terms of the Contract Documents, the provisions of the doclUTIent listed first below over those of a document listed later: I. Contract Agreement Fonn 2. Special Provisions 3. Plans G-l5 G-16 I I I I I I I I I I I I I I I I I I I 4. Specifications 5. General Conditions 6. Bid 7. Bid Form Special provisions and detail plans are intended to modify and prevail over standard plans and specifications. 5.08 DISCREPANCIES IN PLANS: The drawings, specifications, and other parts of the plans are intended to complement one another. Anything shown on the drawings but not mentioned in the specifications, or vice versa, or anything not expressly set forth in either but which is reasonably implied, shall be furnished as though specifically shown and mentioned in both without any extra charge. Should anything be omitted from the drawings and necessary to the proper construction of the work herein described, it shall be the duty of the Contractor to notify the Engineer prior to beginning work; and in the event of the Contractor failing to give such notice, the Contractor shall make good any damage or defect in work caused thereby, without extra charge to the owner. . Questions as to meaning of plans and specifications shall be interpreted by the Engineer, whose decisions shall be final and binding on all parties concerned. (See also Section 5.01 of these General Conditions.) The Engineer will provide the Contractor with such information as may be required to show revised or additional details of construction. The Engineer will provide full information when errors or omissions in the plans and specifications are discovered. Any work done by the Contractor, after discovery of such discrepancies, errors or omissions and prior to a decision by the Engineer, shall be done at the Contractor's risk. 5.09 SEPARATE CONTRACTS: The Owner reserves the right to let other contracts in connection with this work. The Contractor shall afford other Contractors reasonable opportunity for the introduction and storage of their materials and the execution of their work and shall properly connect and coordinate the work with that of other contractors. If any part of the Contractor's work depends for proper execution or results upon the work of any other Contractor, the Contractor shall inspect and promptly report to the Engineer any defects in such work that render it unsuitable for such proper execution and results. Failure to so inspect and report shall constitute an acceptance of the other Contractor's work. To insure the proper execution of the work, the Contractor shall measure work already in place and shall at once report to the Engineer any discrepancy between the executed work and the drawings. 5.10 PLANS AND SPECIFICATIONS AT JOB SITE: One complete set of all plans and specifications shall be maintained by the Contractor at the job site and shall be available to the Engineer at all times. I I I I I I I I I I I I I I I I I I I 5.11 5.12 The Owner retains the right of access to all plans, specifications and drawings. MOVING OF PUBLIC AND PRIVATE UTILITIES: The Owner will give reasonable notice to all affected utility companies of the potential necessity of movement of their installations prior to commencement of the work. It shall be the responsibility of the Contractor to coordinate the work with the utility companies. It is provided that no utility, private or public, shall be moved to accommodate the Contractor's equipment or the method of operation when such utility does not conflict with the installation of the improvement under construction unless the costs of such removal shall be at the expense of the Contractor. The Contractor shall notify the proper representatives of any public utility, corporation, and company or individual, not less than 48 hours in advance of any work which might damage or interfere with the operation of their or his property along or adjacent to the work. PROTECTION OF EXISTING IMPROVEMENTS AND UTILITIES: Prior to construction, the Contractor shall obtain field locations or other assistance as may be required to determine the existence and location of gas main and other private utilities as well as public utilities of the City, County, or State which may be underground or overhead within street and highway right of way or within easements and which may be interfered with under this contract. In cases where the alignment, as shown on the plans, coincides with the existing location of either an overhead or underground privately owned utility so that, in the opinion of the Engineer, the relocation of said utility is required to complete the installation, the Owner shall provide for such relocation unless specified otherwise in the Special Provisions. Existing underground, surface or overhead structures are not necessarily shown on the plans. Those shown are only approximate and no responsibility is assumed by the Owner or the Engineer for the accuracy of location. The Contractor shall make such investigations as are necessary to determine the extent to which existing structures may interfere with the work contemplated under this contract. The sizes, locations and depths of such structures as are shown on the plans and profiles are only approximate and the Contractor shall verifY the accuracy of the information given. The Contractor shall support and protect by timbers or otherwise, all pipes, conduits, poles, wires or other apparatus which may be in any way affected by the work.

No trees shall be cut except upon the specific authority of the Engineer. Trees adjacent to the work shall be protected from all damage by the construction operations. Storm and sanitary sewers must be carefully protected from any sand or debris and any such deposition caused by the Contractor's operations must be removed from the manholes and pipes by the Contractor. Prior to construction commencement, the Contractor shall notifY the Owner and conduct an inspection of potentially affected existing public utilities noting conditions such as sand in manholes or damaged valve boxes prior to the Contractor's construction. Once construction has commenced it will be assumed that all damage to surface and underground installations not previously noted has been caused by the Contractor's operations. The Contractor will be responsible to make the necessary corrections and/or repairs. 5.13 DAMAGE TO EXISTING IMPROVEMENTS OR UTILITIES: If, through the Contractor's operations, any of said pipes, conduits, poles, wires, or apparatus should be damaged, they shall be repaired by the authorities having control of same, and the expense of such repairs shall be charged to the Contractor. The Contractor shall indemnifY and save the Owner and Engineer harmless from claims for any damage done to any street or other public property; or to any private property by reason of breaking of any water pipe, sewer or gas pipe, electric conduit, or other utility by or through the Contractor's negligence. The Contractor shall restore, or have restored at his own cost and expense, such property to a condition similar or equal to that existing before such damage or injUl)' was done, by repairing, rebuilding, or otherwise restoring as may be directed, or shall make good such damage from injUl)' in a manner acceptable to the Owner or the Engineer. In case of failure on the part of the Contractor to restore such property or make good such damage or injury, the Engineer may, upon 48 hours written notice under ordinary circumstances and without notice when a nuisance or hazardous condition results, proceed to repair, rebuild, or otherwise restore such property as may be determined necessary, and the cost thereof will be deducted from any moneys due to the Contractor under this contract and if not so deducted, the Contractor will be obligated to forth with reimburse the Owner for the cost thereof. The Contractor shall indemnifY and save the Owner and Engineer harmless from claims brought for or on account of any damage, maintenance, removal or replacement, or relocation of mains, conduits, pipes, wires, cables or other such structures of private utility ftrms or corporations, whether underground or overhead, that may be caused or required by the Contractor during the time the work is in progress. I I I I I I I I I I I I I I I I I I I 5.14 The Contractor shall not claim or be entitled to receive compensation for any damages sustained by reason of the inaccuracy or the omission of any of the information given on the drawings, relative to the surface, overhead, or underground structures or by reason ofthe Contractor's failure to properly protect and to maintain such structures. The Contractor is to exercise extreme care in crossing or working adjacent to all utilities and shall be responsible to protect and maintain their operation during the time the work is in progress. The Contractor shall restore, at no cost to the Owner, any public structures such as watermains, water connections and appurtenances, sewers, manholes, catch basins and sewer connections which are damaged or injured in any way by his acts. No trees shall be removed without permission of the Engineer. No compensation will be paid for cutting down, removing and disposing of shrubs. Any trees or shrubs deemed savable will be field located by the Engineer and shall be fully protected by this Contractor during construction. Any trees removed or damaged by the Contractor, which were deemed savable by the Engineer, will be replaced at the Contractor's expense with a new tree as near in size and kind as possible, but never larger than 6" in diameter as measured 2 feet above the ground surface. All trimming of trees has to be approved by the Engineer. All trees damaged during construction shall be trimmed and repaired. The following procedures shall be adhered to when constructing utilities near trees. a. Cut roots cleanly. b. Backfill trench as soon as possible; do not leave the roots exposed to air. c. No equipment or construction materials shall be stored beneath a tree's drip line. d. Clean up around trees immediately after construction.

This work shall be resmned by the Contractor within ten days after the date fixed in a supplemental written notice from the Owner to the Contractor to do so. If the work, or any part thereof, shall be stopped by the notice in writing aforesaid, and if the Owner does not give a supplemental notice in writing to the Contractor to resmne work at a date within a year of the date fixed in the written notice to suspend, then the Contractor may abandon that portion of the work so suspended, and he will be entitled to the estimates and payments for all work done on the portions so abandoned, if any. If suspension of all or part of the work, which is subsequently resmned, causes additional expenses not due to the fault or negligence of the Contractor, the Owner shall reimburse the Contractor for additional expense incurred due to suspension of the work. Claims for such compensation, with complete substantiating records, shall be filed with the Owner within ten days after the date or order to resmne work in I I I I I I I I I I I I I I I I I I I 5.23 order to receive consideration. This paragraph shall not be construed as entitling the Contractor to compensation for delays due to inclement weather, failure to furnish additional surety or sureties specified herein, for supervision made at the request of the Contractor, or for any other delay provided for in the Contract Documents. ARBITRATION: Should there be a dispute about any matter involving the decision of the Engineer which is subject to arbitration (less than $ I 0,000), the dispute shall be promptly submitted to arbitration upon demand by either party to the Contract (see Section 5.01 of the General Conditions). The Contractor shall not delay the work because arbitration proceedings are pending unless he shall have written permission from the Engineer or Owner is given and such delay shall not extend beyond the time when the arbitrators shall have opportunity to determine whether the work shall continue or be suspended pending decision by the arbitrators of such a dispute.

Should the Engineer fail within a reasonable period to make a decision, a demand for arbitration may then be made as if the Engineer's decision had been rendered against the party demanding arbitration. No one shall be qualified to act as an arbitrator who has, directly or indirectly, any financial interest in the contract or who has any business or family relationship with the Owner, the Contractor, or the Engineer. Each arbitrator selected shall be qualified by experience and knowledge of the work involved in the matter to be submitted to arbitration. Arbitration shall be conducted in accordance with the Uniform Arbitration Act, Minnesota Statutes, Chapter 572, and the Construction Industry Arbitration Rules of the American Arbitration Association. G-23 0-24 I I I I I I I I I I I I I I I I I I I SECTION 6.00 - CONTROL OF MATERIALS AND WORKMANSHIP 6.01 QUALITY OF EQUIPMENT AND MATERIALS: In order to establish standards of quality, the Engineer has, in the detailed specifications, referred to certain products by name and catalog number. This procedure is not to be construed as eliminating from competition other products of equal or better quality by other manufacturers where fully suitable in design. Whenever in these specifications, a material or article is specified by using the specific description or name of proprietary product, or name of a manufacturer or vendor, rather than by using descriptive detail or substance and function, any article which will perform the duties imposed adequately and to the same effectiveness as determined by the Engineer will be acceptable as a substitute in lieu of the material or articles so specified. Only materials conforming to the requirements of these specifications shall be used in the work. The source of any material shall not be changed at any time without the written approval of the Engineer. The Contractor may be required at any time to furnish a complete statement of the original, composition and manufacturer of any or all materials required in the work, or to submit samples ofthe same. Unless otherwise specified, all materials shall be new and both workmanship and material shall be of good quality. The Contractor shall, if required, furnish satisfactory evidence as to the kind and quality of materials or tools used in the work. All materials, supplies and articles furnished shall, whenever so specified, and otherwise wherever practicable, be the standard stock products of recognized reputable manufacturers. The Contractor shall furnish a complete list of proposed desired substitutions, together with such engineering and catalog data as the Engineer may require. List and information must be submitted prior to submittal of first progress payment estimate. The Contractor shall abide by the Engineer's judgment when proposed substitute materials or items of equipment are judged to be unacceptable and shall furnish the specified material or item of equipment in such case. All proposals for substitutions shall be submitted in writing by the Contractor and not by individual trades or material suppliers. The Engineer will approve or disapprove proposed substitutions in writing within a reasonable time. No substitute materials shall be used unless so approved in writing. 6.02 TESTING: All testing of materials and workmanship shall be conducted by a reputable and qualified firm totally independent of the contractor and owner. 6.03 USE OF PREMISES: The Contractor shall confine equipment, storage of materials and operation of work to the limits indicated by law, ordinances, permits, easements I I I I I I I I I I I I I I I I I I I 6.04 6.05 6.06 or direction of the Engineer, and shall not unreasonably encumber the premises with said equipment and materials. STORAGE OF MATERIALS: Materials shall be stored so as to insure the preservation of their quality and fitness for the work and such materials, even though approved before storage, shall be subject to testing and must meet the requirement of these specifications at the time it is proposed to use them in the work. Materials shall be stored in a safe manner that will facilitate inspection. The portion of the right of way not required for public travel may, with the consent of the Engineer, be used for storage purposes, and for the placing of the Contractor's plant and equipment; but any additional space required; unless otherwise stipulated, shall be provided by the Contractor at no cost to the owner. From the commencement of the work until the completion of the same, the Contractor shall be solely responsible for the care of the work covered by this contract and for the materials delivered at the site intended to be used in the work and all injury or damage to the same from whatever cause, shall be made good at the Contractor's expense before the [mal estimate is made. The Contractor shall provide suitable means of protection for and shall protect all material intended to be used in the work and all work in progress as well as completed work. AIl necessary precautions shall be taken to prevent injury or damage to work in progress of construction by flood, freezing or from inclemency's of the weather at any and all times and only approved methods shall be used for this pUIpose. MANUFACTURER'S DIRECTIONS: Manufactured articles, material and equipment shall be applied, installed, connected, erected, used, cleaned and conditioned as directed by the manufacturer unless herein specified to the contrary. REJECTED WORK AND MATERIALS: All materials which do not conform to the requirements of the Contract Documents are not equal to samples approved by the Engineer, or are in any way unsatisfactory or unsuited to the puzpose for which they are intended, shall be rejected and shall be removed immediately from the Project, unless otherwise permitted. No materials which have been rejected - the defects on which have been corrected or removed - shall be used until approval has been given. If the Contractor does not remove such condemned work and materials within a reasonable time fixed by written notice, the Owner may remove them and may store the materials at the expense of the Contractor.

In all cases, the Contractor shall notify the Engineer of the emergency as soon as practicable, but shall not wait for instructions before proceeding to properly protect both life and property. In cases where the Contractor cannot or does not meet the emergency, the Owner may take appropriate action to protect life and safety. 8.07 DELAYS AND EXTENSION OF CONTRACT TIME: The Contractor herewith specifically waives claims for damages for any hindrance, delay, or change of sequencing. The Contractor will, in lieu thereof, be granted extensions of time for which liquidated damages will not be claimed by the Owner for the following causes: A delay caused the Contractor by any suit or other legal action against the Owner will entitle the Contractor to an equivalent extension oftime unless the period of such delay exceeds 90 days. When such period is exceeded, the Owner will, upon request by the Contractor in writing, either terminate the contract, or grant a further extension of time, whichever as may at that time appear most desirable to both parties. If the Contractor is delayed at any time in the progress of the work by any act of neglect of the Owner or the Engineer or any employees of either, or by any other Contractor employed by the Owner, or by strike, fire, unusual delay in transportation, unavoidable casualties, or other causes beyond the Contractor's control, or by any cause which, in the opinion of the Engineer, shall justify the delay, then the time 'of completion shall be extended for such reasonable time as the Engineer may decide. No such extension shall be made for delay occurring more than seven days before claim therefore is made in writing to the Engineer. I I I I I I I I I I I I I I I I I I I 8.08 Shutdowns due to improper work, or otherwise due the Contractor's operation, are not cause for extension oftime. If during the term of this contract, the volume of the specified work, measured in dollars, is increased over the total value shown in the Contractor's proposal at the time the award of contract is made, the Contractor will be granted an extension proportionately equal to the increase in the total value. Should unforeseen conditions require the performance under an extra work order, the work more complex or dif- ficult than that originally specified and shown on the plans, and such work, in the Contractor's opinion, requires more time to execute than the proportional increase in dollar value, the Contractor shall state to the Engineer, in writing, prior to the performance of such work, his estimate of the added time required for such work. The Owner will, if such estimate be reasonable, allow an added extension of time equal to the difference between the total time required and the proportional increase in the dollar value ofthe work. CONSTRUCTION SCHEDULE AND LIQUIDATED DAMAGES: After being awarded the contract, the Contractor shall prepare and submit to the Engineer for approval a bar chart progress schedule which will insure the completion of the project within the time specified. The date of beginning and the time for completion of the work are essential conditions of the Contract Documents and the work embraced shall be commenced on the date specified in the notice to proceed and shall be completed on the date specified in the special provisions. The Contractor will proceed with the work at such rate of progress to insure full completion within the contract time. It is expressly understood and agreed, by and between the Contractor and the Owner, that the contract time for the completion of the work described herein is a reasonable time, taking into consideration the average climatic and economic conditions and other factors prevailing in the locality of the work. If the Contractor shall fail to satisfactorily complete any portion of work under this contract by the specified completion date, the Owner shall deduct from the payments due the Contractor liquidated damages for each and every calendar day that the work remains uncompleted beyond the completion date. Due to the difficulty in precisely determining Owner's damages for late completion, the Contractor will be assessed a daily charge, not as a penalty but as liquidated damages to compensate Owner for the additional costs caused by the delay. Contractor agrees that the daily amount of liquidated damages is a reasonable estimate of Owner's damages for late completion. In addition, the Contractor shall pay the inspector's hours, travel, and any other associated costs for all inspection work required past the completion date. G-35 G-36 I I I I I I I I I I I I I I I I I I I If such payments due the Contractor are less than the amount of such liquidated damages, said damages shall be deducted from any other moneys due or to become due the Contractor, and in case such damages shall exceed the amount of all moneys due to the Contractor, then the Contractor or the surety shall pay the balance to the Owner. SCHEDULE OF LIQUIDATED DAMAGES Original Contract Amount Charge Per Calendar Dav From More Than To and IndudiDl! $0 $500,000 $600 $500,000 $1,000,000 $650 $1,000,000 $2,000,000 $700 $2,000,000 --- $800 8.09 OWNER'S RIGHT TO TERMINATE CONTRACT AND COMPLETE THE WORK: The Owner has the right to terminate the employment of the Contractor for any of the following reasons: (1) The Contractor is adjudged bankrupt, makes a general assignment for the benefit of creditors, or becomes insolvent; (2) Failure of Contractor to supply adequate properly skilled workmen or proper materials; (3) Failure of Contractor to make prompt payment to subcontractor for material or labor; (4) Persistent and continuing disregard of laws, ordinances, or proper instructions of the Engineer; (5) Assignment of work without permission of the Owner; (6) Abandonment of the work by Contractor; (7) Failure to meet the work progress schedule set forth in the contract; Termination of the contract shall be preceded by seven days written notice by the Owner to the Contractor and the surety stating the ground for tennination and the measures if any which must be taken to assure compliance with the contract. The contract shall be terminated at the expiration of such seven day period unless the Owner shall withdraw its notice of termination. I I I I I I I I I I I I I I I I I I I 8.10 Upon termination of the contract by the Owner, the Owner may complete the work required by the contract by whatever means deemed expedient, including requiring the Contractor's surety to complete the work. The taking over of the work by the Owner upon contract termination shall not affect the right of the Owner to recover liquidated damages from the Contractor or the surety for failure to complete contract. In the event that the Contractor involuntarily abandons the work, fails or refuses to complete the work embodied in the contract or fails to pay just claims for labor or material, the Owner reserves the right to charge against the Contractor all extra legal, engineering, or other costs resulting from such abandonment, failure or refusal. _ Legal costs will include the Owner's cost of prosecuting or defending any suit in connection with such abandonment, failure or refusal, and nonpayment of claims wherein the Owner is made codefendant, and the Contractor agrees to pay all such costs, including reasonable attorney's fees. When the Owner assumes control of the work under the contract pursuant to termination, the Owner may take possession of the work and all material, tools, and equipment therein belonging to the Contractor and may use the same to complete the work at Contractor's expense. Upon contract termination, the Contractor shall not be entitled to receive any further payment until the work is fInished. If the unpaid balance of the contract price exceeds the expense of fmishing the work, including compensation for additional managerial and administrative services, the excess shall be paid to the Contractor. If such expense exceeds the unpaid balance, the Contractor shall pay the difference to the Owner. The expenses incurred by the Owner as herein provided and the damages incurred through the Contractor's default shall be certifIed by the Engineer and Owner. CONTRACTOR'S RIGHT TO TERMINATE CONTRACT: The Contractor may terminate contract upon ten days' written notice to the Owner and the Engineer for any of the following reas9ns: (1) If an order of any court or other public authority caused the work to be stopped or suspended for a period of 90 days through no act of fault of the Contractor or his employees.

(3) If the Owner should fail to pay the Contractor any sum within 45 days after its award by arbitrators.

In the event the actual quantities differ more than 25% of the original contract an10unt, an equitable revision of the unit price shall be made when requested by either the Owner or the Contractor. This 25 percent limit does not apply to items specifically excluded or listed as optional by the Owner, nor to minor contract items, (items amounting to ten percent or less of the total contract). (B) FOR ITEMS NOT COVERED BY THE PLANS AND SPECIFICATIONS: If the Engineer orders, in writing, the perfonnance of any work not covered by the plans or included in the specifications, and for which no item in the contract is provided, and for which no unit price or lump sum basis can be agreed upon, then such extra work shall be done on a cost-plus-percentage basis of payment as follows: I I I I I I I I I I I I I I I I I I I 1.
