SUE MCDERMOTT, CITY ENGINEER
CONSIDER APPROVAL OF CHANGE ORDER NO.2 AND
FINAL PAYMENT FOR CITY PROJECT 99-02 LIFT
STATION RENOVATIONS.
DISCUSSION:
HISTORY
Project #99-02 is the lift station renovation project that was
included in the 1999 Capital Improvement Program. The City has
entered into a contract for public improvements with Braun Pump
and Controls of New Prague, MN. This renovation program is
intended to renew three of thirty-one lift stations. By renovating
three lift stations per year, our objective is to maintain the
dependability of each to avoid breakdowns which negatively affect
our sewer customers.
The following items were changed during construction:
1. The City's record drawings showed a 2" force main at Lift
Station #13. When the contractor exposed the force main, it
was actually a 3" diameter pipe. Extra time was spent to
obtain the correct fittings and reconnect the force main.
Cost to correct: $675.00.
2. Due to the small diameter wet wells, the transducer, which
was specified and installed was giving false readings which
caused false lift station alarms. At the time the
specifications were prepared, staff was unaware that there
was a different type of transducer available for this
application. Cost to replace: $481.75.
3. The access covers that were specified for Lift Stations #9
and #13 were too large to be structurally safe and had to be
reordered at a cost of $950.00 each.
