The bids were tabulated and minor errors were found; however, they did not change the low
bidder. 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. Funding for the total project cost
(including all indirect costs) is proposed as follows:

Re: 2007 Koehnen Area Improvements
Chanhassen, MN
Dear Mr. Oehme,
On March 16, 2007 S.M. 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.
