Hentges & Sons, Inc. in the amount of $2,271,502.88 for the Koehnen Area/Yosemite Avenue street and utility reconstruction. BACKGROUND On January 8, 2007, Council approved the plans and specifications and authorized the advertisement for bids for the Koehnen Area/Yosemite A venue street and utility reconstruction project. The improvements included in this project are as follows: . Reconstruction of Yosemite A venue, Blue Jay Circle, Audubon Circle, Cardinal A venue, West 63rd Street, and Koehnen Circle East and West. · Replacement of all watermain. . Replacement of approximately 1,900 feet of sanitary sewer. · Installation of storm sewer and construction of three storm water These improvements are proposed to be constructed during the.2007 construction season. Bids were opened for the project on Thursday, March 15, 2007 at 10:00 A summary of bidders and bid amounts are as follows: Bidder Base Bid Amount S.M. Hentges & Sons, Inc. $2,271,502.88 Park Construction Company $2,396,883.36 Minger Construction, Inc. $2,526,148.30 S.R.

The bid was submitted with a proper bid guarantee in the amount of 5% of the bid. S.M. Hentges & Sons, Inc. was the low bidder with a total base bid amount of $2,271,502.88. The low bid is approximately 15% less than the Engineer's Estimate. The bid was also lower then the estimate in the feasibility study. The bids included a bid alternate for the construction of surmountable curb and gutter. This alternate was included since a couple of residents requested surmountable curb and gutter instead of the high-back curb and gutter. At the April!!, 2007 neighborhood meeting, residents did not express a preference for either type of curb and gutter. The high-back curb and gutter design provides for better storm water flow and reduces the likelihood of sod damage from snow plow operations. Also, the high back curb provides less of a bump at driveway entrances. This bid alternate would result in a deduct of $2,950.50. Staff recommends that this bid alternate not be accepted due to the performance benefits of the high-back curb and gutter and since it is not a substantial cost difference between the surmountable curb. A bid alternate was also submitted for the installation of High Density Polyethylene (HDPE) storm sewer pipe in lieu of reinforced concrete pipe. This alternate was included due to potential cost savings. This bid alternate would result in a deduction of $13,306.29. Staff has reviewed this bid alternative and is recommending the Council not accept the alternate. In discussions with contractors and other consultants the pipe may cause more problems in the future then it is worth with a short up front cost savings. S.M. Hentges & Sons, Inc. is working on City Project 06-05,2005 MUSA Phase I improvements and has worked on other development projects within the City. They are also working on the MnDOT 101 GAP project. S.M. Hentges & Sons, Inc. work has been satisfactory. Award of the contract is recommended to S.M. Hentges & Sons, Inc. Funding for this project is proposed through a combination of special assessments to the benefiting properties, revolving assessment funds, MnDOT State Aid funds, storm sewer utility funds, water utility funds, and sanitary sewer utility funds. The special assessment amount for individual property owners is $6,390.81/1ot and is based on the bid price. Any additional project costs will be funded through a combination of revolving assessment funds, storm sewer utility funds, water utility funds, and sanitary sewer utility funds.

Hentges & Sons Inc. submitted a bid for the Koehnen Area Impro'"ements and is the apparent low bidder. ' The proposal has an alternate B for the substituting surmoun~able curb and gutter instead of 6618 'that was in the base bid. S.M. Hentges & Sons rnc. during the writing out of our proposal indirectly bid that alternat<!! B surmountable ctJrb as a .25 IF credit instead of a .25 LF add. The base bid 8618 fits the catch basin castings and IS used at all radiuses regardless of the (;urb styles. . Trying to adapt B618 to surmountable curb at all eaten basins and radius can be done but tl1e final product does not look as nice as if were all B618. Please use the base bid of B618 curb on this project as it will fit and look all the same throughout the job. If you have any questions please feel free to give me a call. 2;~ .Senior Project Manager "'- Equal OpportunUy Employer ~<'1"'T"<~~ ,~~ 'Ii..".;;;;;,sJ11 C;Vl/7.Vl -=l~\'j,..l C"":Jt:'Ii I J..'":1I_' 1.1i'"
