2008 Street Improvement Project 08-01: Award Construction Contract
REQUESTED ACTION
Approve resolution accepting bid and awarding a contract to S.M. Hentges & Sons, Inc. in
the amount of $2,442,134.20, base bid plus Alternate No.3, for the 2008 Street
Improvements - Laredo Drive Area.
BACKGROUND
The City's Pavement Management Program recommends that streets in the Laredo Drive area
be reconstructed. The City receives the most complaints about the condition of Laredo Drive
from residents and the traveling public than any other street in the system. The public
utilities in the area are old, have had many problems and should be replaced or repaired.
Approximately 1.35 miles of streets are proposed tobe reconstructed. Thearea for
improvements include: Laredo Drive, Laredo Lane, Longview Circle, Cilllarron Circle and
Highland Drive (west of Laredo Drive).
All the streets are proposed to be reconstructed approximately thesaInewidtha~lhe existing
streets. Laredo Drive between West 78th Street and Saratoga Driveisproposedtobebuiltto
a 36-foot wide urban street section. Laredo Drive from Saratoga DrivetoProntierTrailjs
proposed to be 31' wide. The side streets are proposed be built to a 28' wide roadway.
The streets are proposed to be urbanized and reconstructed with.concretecurband.gutter.
Most streets currently have bituminous curb or concrete curb and gutter. Replacement of the
existing sidewalk panels is included in the project. No additionalsidewalkortrail
improvements are included in the project at this time. No street light improvemehtsare
included in the project.
The reconstruction project will include the improvement or replacement of most public
utilities within the reconstruction project area. The watermain in this area is mainly cast iron
pipe which has experienced numerous breaks over the past few years. It is proposed to
replace all the watermain with PVC watermain pipe. Water service pipes and curb stop boxes
are proposed to be replaced.
The sanitary sewer service has been televised and approximately 1000' of sanitary sewer pipe
is proposed to be replaced. Also, several sanitary service pipes to residential properties have
been identified as needing replacement. Most of the pipes proposed to be replaced are clay
pipe that has off-set joints, cracks ()rgrOllndwaterinfiltration problems. By replacing this
pipe, it is anticipated that the City will see a reduction of inflow/infiltration (1&1). This
reduction will be quantified and included in the City's MCES 1&1 surcharge reduction plan
The City 01 Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

for credits. Along with the sanitary sewer pipe, sanitary sewer services will be replaced to
the right-of-way line at sewer mainline replacement areas.
The project includes replacement and installation of additional storm sewer within the streets.
Three environmental manholes are proposed in the project area to help treat the runoff prior
to discharging into adjacent water bodies. Over 9,000 feet of draintile is included in various
areas along the street to pick up residential sump pump water discharge and reduce the
amount of groundwater in the street subgrade. Reducing the amount of groundwater in
subsoils should increase the pavement strength. The Watershed District may embark on a
raingarden program in this area in the future with property owner participation and City
approval. The contractor to who makes these improvements should be able to connect to the
draintile system to redirect the water. Staff will need to work with the Watershed District in
the future on any potential infiltration areas in the City right-of-way.
A storm water pond is proposed in Kerber Pond Park to treat run off from Longview Circle,
Saratoga Drive and some runoff from Laredo Drive. The total watershed proposed to be
treated under a 10-year storm event in the new pond is 14 acres. Staff has discussed this
project with the adjacent property owners and Park Commission. An area in Kerber Pond
Park has been identified that does not need much grading work to construct a pond.
Additionally, the area adjacent to the trail extending from Laredo Drive to Kerber Pond Park
is proposed as an infiltration/filtration area. These storm water improvements were bid out as
an alternate to the base bid.
The proposed improvements would have the following benefits:
· The proposed pond improvement allows for a large area of runoff to be treated before
it enters Lotus Lake.
· The improvements would lengthen the time the water would get to the lake thereby
helping to reduce the high water levels in the lake after major storm events.
· The improvements would promote infiltration and thereby decrease the overall
volume reaching Lotus Lake. This would be credited towards the nondegradation
portion of the City's MS4 Permit.
· By diverting the runoff into Kerber Park Pond, the Iroquois drainage system, where it
currently flows would function better and future downstream storm water
improvements may not need to be as large.
. By correcting the soils in the area adjacent to the trail, the frequent impoundment of
water which occurs on and adjacent to the trail will be ameliorated.
· This project would provide credit to the forthcoming Total Maximum Daily Load
(TMDL) for Lotus Lake which a pond alone would not proffer.
The project does not include replanting of trees or shrubs. Staff is proposing to contract this
work out separately next spring. Seeding and erosion control are including in the contract.
BIDS
Bids were opened for the project on Thursday, April 10, 2008, at 2:00p.m. Eight contractors

Engineer's estimate $2,736,058.50 -$17,876.00 $193,075.00 $241,856.00
The project had 3 alternate bids.
Alternate 1 included 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 $1,334.00. 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 upfront cost savings. Alternate 2 includes the
Kerber Park pond improvements without the infiltration/filtration area improvements
adjacent to the trial. Staff is not recommending awarding this alternate. Alternate 3
includes the Kerber Park Pond improvements with the infiltration/filtration area
improvements adjacent to the trial. Staff is recommending awarding this alternate.
Bids were tabulated and minor errors were found; however, they did not change the low
bidder. The bids were 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 $2,252,532.00.
The bid was also lower then the estimate in the feasibility study. The total recommended
contact for this project including the base bid and alternate 3 is $2,442,134.20.
S.M. Hentges & Sons, Inc. has completed the 2005 MUSA Phase I improvements, Bluff
Creek Boulevard Improvements, worked on several development projects within the City,
and was the contractor for last year's street reconstruction project in the Koehnen area. They
have also completed the MnDOT 101 GAP project. S.M. Hentges & Sons, Inc.'s work has
been satisfactory. Award ofthe contract is recommended to S.M. Hentges & Sons, Inc.

Description
Annual project to rehabilitate and reconstruct streets in the City. Current 5-year plan shows the following neighborhood areas:
Residential 2008 - Laredo Dr/Ln, Longview Dr, Cimarron Circle, and Highland Drive
2009 - Chaparral and Saratoga Dr/Cir
2010 - Erie Ave area and Red Cedar Pt
2011 - Carver Beach Rd area, Sandy Hook Rd area, Holly Ln, Royal Oak Estates, Crimson Bay, Ches Mar and Timberwood

MSA 2009 - Audubon Road Lyman Blvd, to Lake Drive West
2010 - West 78th Street
Justification
The City uses a Pavement Management System to monitor the condition ofthe City streets. While proper preventative maintenance extends the
life of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective.
Rehabilitation projects extend the life of the street. In cases with utility or poor subgrade needs to be replaced or where streets have deteriorated to
a point where rehabilitation will no longer be practical reconstruction ofthe street is necessary. t) feasibiljty study is written to. consider the merits
ofthe project and scope of work. . '.'.,"
