BOX 147 •• CHANHASSEN, MINNESOTA 55317 _. 1 (612) 937-1900 MEMORANDUM ITO: Don Ashworth, City Manager FROM: Gary Warren, City Engineer I -. DATE: March 10, 1988 1 SUBJ: Approval of Change Order No. 1, Shafer Contracting, Inc. Downtown Redevelopment Project Phase I File No. 86-11A I . Attached you will find a memo from Gary Ehret of BRW which in 1 detail summarizes the request for Change Order No. 1 for Shafer Contracting on the Downtown Redevelopment Project. I have spent the better part of a day on February 22 , 1988 reviewing each of II these items in detail with BRW staff. I found that both Shafer Contracting and BRW have maintained excellent records documenting the exact quantities of materials utilized on the project. II am sure if one takes the time to go down the itemized list con- tained in Mr. Ehret' s letter that there will be a number of things that are familiar such as item #37, water used for dust 1 control, item #42, signage used throughout the project area emphasizing the downtown business availability and access, etc. Likewise, there are quantity underruns and other deducts which are anticipated on this contract as indicated in the letter. Mr. I Ehret and I will be happy to go into more detail on any of the items as requested Monday night. II therefore recommend approval of Change Order No. 1 in the amount of $291, 201. 66 as itemized in the March 9 , 1988 correspon- dence from BRW and establishing a revised contract estimated I ceiling of $2,725,772 . 96. The contract completion date remains June 1 , 1988. I Attachments: 1. March 9 , 1988 correspondence from BRW 2 . Change Order No. 1 I I I PLANNING TRANSPORTATION ENGINEERING ARCHITECTURE BENNETT.

City Engineer ENGINEERING DEPT. RE: Contract Status Downtown Redevelopment Project ' CP 86-11 Dear Mr. Warren: ' Partial Payment #6 for Shafer Contracting was submitted to your office for review, approval , and payment in the amount of $100,158.21 on March 8, 1988. This payment is based upon $1,728,953.62 of approved work todate on the downtown project. The partial payment has been made based upon completed work items which have contract unit bid prices. Several areas of work have been completed but contract unit bid prices are not in force so these items have not been paid. I Change Order Number One (1) to the downtown project is being submitted for approval and City Council action at this time. This change order is intended to cover items of work not covered by the original contract bid items, as well as to modify those current bid items which have significantly changed thru the course of the project. This letter and change order are intended to provide both you and the City Council the following information: 1. Contract Status Update ' 2. Projected Contract Status 3. Summary Explanation of Change Order Number One In regard to the contract status update, upon approval of the City Council , the revised contract will be: Original Contract Amount $2,434,571.30 I Change Order Number One (1) 291,201.66 Revised Contract Amount $2,725,772.96 DAVID J BENNETT DONALD W RINGROSE RICHARD P WOLSFELD PETER E JARVIS LAWRENCE J GARDNER THOMAS F CARROLL CRAIG A AMUNDSEN DONALD E HUNT MARK G SWENSON JOHN B McNAMARA DONALD L CRAIG RICHARD D.PILGRIM DALE N BECKMANN DENNIS J SUTLIFF MINNEAPOLIS DENVER PHOENIX I Mr. Gary Warren ' March 9, 1988 Page 2 i Change Order Number One addresses all significant contract additions or ' increases todate; however, it does not address contract deletions, reductions, or potential changes this spring. We have reviewed the contract as well as the work completed todate and have found that there will be additional significant ' changes to the contract prior to completion of the project. Included in these changes are contract quantity underruns, change order deductions, and reduced compensation due to the contractor's failure to meet the project specifications. ' In order to illustrate the projected contract status we offer the following summary: Original Contract Amount $2,434,571.30 Add Change Order Number One (1) 291,201.66 Add Change Order Number Two (2) (Future) 5,000.00 Deduct Projected Quantity Underruns <29,000.00> Deduct Contractor Penalties <3,500.00> ' Deduct Future Change Order <18,750.00> PROJECTED CONTRACT STATUS $2,679,522.96 It is important to note that this projected contract status is based wholly upon the scope of work identified in Shafer Contracting's current contract. Any ' scope of work changes, whether reductions or additions, obviously have an impact on this projection. ' Finally, we offer an encapsulated explanation of the changes illustrated in Change Order Number One, which is attached to this letter. As you are aware, we have reviewed each of the change order items with you previously and BRW will provide detailed support documentation for each of the changes.
