Wells 12 & 13 Improvement Project Nos. 08-04 & 08-05: Approve
Bid and A ward Contract
REQUEST
Staff requests the City Council approve a bid and a construction contract in the
amount of $ 1,261,950.00 to Mark J. Traut Wells, Inc. for work to be performed on
the above-referenced project.
BACKGROUND
On October 22, 2007, Council authorized a consultant contract with Barr Engineering
Co. for the improvements to Well Nos. 12 and 13.
On November 13,2007, staff held a neighborhood meeting for surrounding property
owners to learn about the project.
On December 10, 2007, Council approved the plans and specifications and authorized
Ad for Bids for the wells.
DISCUSSION
Proposed Wells 12 and 13 are intended to replace the production capacity that was
lost last summer when Wells 5 and 6 failed. When the project was authorized, six
potential well site alternatives were identified for the new well locations. Additional
well sites were considered preliminarily that were further away from the east water
treatment plant but these sites were ruled out at this time because of various reasons
including time constraints. Based on the modeling work completed, it is anticipated
the two new wells may each yield 1,100 gpm. Well 12 is located near existing Lift
Station No. 12 in South Lotus Lake Park. The lift station is scheduled for
rehabilitation in 2009. In anticipation of that project, the electrical transformer and
electrical vault installed for Well 12 will be sized accordingly to allow for it to be
used in the future for Lift Station No. 12. This will allow for the lift station control
panel to be located underground and only one transformer at the site rather than two.
Well 13 will be located in Chanhassen Estates Park. The City currently does not own
the 25' strip of land along Lake Drive which includes the tree line. Staff is working

with the owner of this property to purchase the strip of property. The purchase of the
property is recommended to save on costs for installation of the raw watermain, have
a better hydraulic alignment of raw watermain, and to give the Parks Department
better access to the park. Staff hopes to have a purchase agreement for Council
consideration for this piece of property at the same time the award of raw watermain
construction contract is considered by Council. In the mean time, the well driller can
access the well site thought a small strip of City owned property.
BIDS
Bids for the project were opened on Thursday, January 10,2008 at 2:00 p.m. One bid
was submitted. The bid was tabulated and no errors were found. The bid received
was as follows:
Base Bid Add Alternate Bid
Mark J. Traut Wells $1,261,950.00 $132,830
The engineer's estimate for the work was $1,242,000. The bid is about 1.6% over the
engineer's estimate. The difference between the engineer's estimate and the bid was
small and occurred due to minor variations in several of the unit prices and is not
attributable to any single, specific issue. The bid is considered reasonable and in line
with the expected price of the project.
An alternate was included for each well. The alternate would allow for each well to
be constructed with a screen if conditions encountered during construction change
from what is expected, as has occurred at previous wells. This alternate was included
to allow for competitively bid unit prices on that option. Based on information about
the Jordan aquifer, staff does not feel a screen well will be needed. As a part of the
project, a test hole will be drilled. The results of the test hole will confirm if a
screened well is needed or not. If the test hole indicates that a screened well is
required, staff will present the Council with a change order to allow for the alternate
bid.
Due to the short schedule of the project, the bid was limited to well construction by
dual rotary methods only. This method of drilling is the only method that should
allow for the project to be completed in the time required. Currently, staff is only
aware of two well drillers in the state that are capable of this type of construction.
The other contractor has been contacted and their equipment is currently committed to
other projects and as a result, they were not able to bid on this work and complete the
project in the time required.
Mark J. Traut Wells has completed several wells for the City in the past including
Wells 9, 10 and 11. Their past work has been acceptable.
