Re: Schedule 4—2023 Kalispell Tank and Wells Project
Meeting Date: 1/16/2024
BACKGROUND: In April of 2023, Council awarded Schedule 4 of the 2023 Kalispell Tank
and Wells Project to S&L Underground for$2,471,184. Schedule 4 is for final development and
construction of the well facility located near the entrance to the Buffalo Hill Golf Course.
Construction of this schedule started in earnest in September and is currently approaching 50%
completion.
At the time of bidding of the project, well development of the North Main Well was incomplete.
The contractor responsible to drill and develop the well (O'Keefe Drilling), encountered higher
than expected concentrations of sand during well development. O'Keefe Drilling completed
additional "air-bursting" techniques in an attempt to remove sand and increase yield but were
met with limited success. Subsequently, a second contractor(Viking Pumps)was brought in to
"block surge" the well for an additional 40 hours. Ultimately, an acceptable well yield was
achieved, but sand concentrations are still above optimal. For these reasons, modifications to the
specifications for the well pump and a sand separator were designed and added into the project.
The well pump specifications were changed to require stainless steel impellers and more robust
bearings to extend the life of the pump. A sand separator is necessary to remove sand before it
enters into the water storage tanks or distribution systems.
Currently, the City has two other sand separators in its water production system. One is installed
at the Grandview Wells Facility, and one is installed at Old School Station Facility. The
separators use a centrifugal filtration to remove sand and sediment. In order to add the sand
separator into the project, design modifications also had to be made to the foundation, above
floor facility piping, electrical, and below floor drainage piping.
An additional change that was identified after bid award was the absence of a requirement for the
contractor to provide and install a transducer for the wells on the project. The transducer
provides staff instantaneous water depths inside the well which allows staff to monitor
drawdown and recharge of the wells. In order to accomplish this, staff negotiated with the
contractor to provide and install the stilling well conduit for the transducer. Water Division staff
will procure and install the transducer prior to programing and startup of the facilities.

A jib-crane was added to the project for future maintenance of the sand separator. Because the
foundation was being poured during the design of the separator and prior to pricing from the
contractor, the contractor was directed to proceed with the modifications to the foundation and
those modifications require reimbursement. Ultimately the jib-crane was removed from the
project due to the price provided by the contractor. If a jib-crane is required for future
maintenance, a design has been completed and the foundation bolts are in place for its
installation. City staff will procure and install the jib-crane, if necessary, at that time.
The Engineer on the project, Robert Peccia and Associates, has negotiated and recommended a
change order to complete or reimburse the contractor for the work described above. The change
order detailing the costs is attached.
REQUESTED ACTION: Motion to approve Change Order 1 for Schedule 4 of the Kalispell
Tank and Wells Project for an increase in the contract price of$95,374.83 for a total contract
price of$2,566,558.83 and the addition of 15 calendar days.
FISCAL EFFECTS: Contingency funds were budgeted and are adequate to cover this increase
in contract price.
