PROPOSED MOTION
"The City Council rejects bids and allows staff to re- advertise for new bids in
2016."
City Council approval requires a simple majority vote of the City Council
present.
BACKGROUND
This project was identified in the 2015 Capital Improvement Plan as "78th Street
Watermain Loop Improvements, W- 055."
This project consists of the construction of approximately 2,100 LF of 10" HDPE
(High Density Poly Ethylene) water main along W. 78th Street from Beacon Court
to Trunk Highway 41. The 10" HDPE has an internal pipe size equivalent to 8"
DIP (ductile iron pipe). This project will provide a second water connection to
and loop the Tanadoona Drive /Dogwood Road/Beacon Court area.
PROJECT PURPOSE AND NEED
The Arbors development is fully built out and is at the end of a 5,850' long water
service that is not looped in the City's system. During high flow events, such as
hydrant flushing, this area has experienced large water hammers that can cause
hot water valves to open, leading to damage inside the properties. Also water
quality is a concern due to the long deadend line.
This project will provide a secondary connection for the area into the City's water
system, creating a loop. This loop connection will provide several benefits:
1. Eliminate the water hammer problem by equalizing the water flow through
the loop.

2. Provide a redundant water source for the area. This will allow the City to better maintain
properties' water service during maintenance operations or emergency water main breaks.
Improve water circulation in this area, which will improve water quality.
BIDS
Bids for the project were opened on Thursday, September 17, 2015 at 2:00 p.m. Three total bids
were submitted. The bids received are as follows:
Bidder
Total Bid

$213,754.29
G.F. Jedlicki, Inc.
$256,380.00
RL Larson Excavating, Inc.
$338,440.00
The project crosses TH 41 and the MnDOT permit requirements added to the cost of the project
that was not anticipated when the project budget was estimated in 2014. Also, additional
hydrants and restoration is needed due to a revised alignment then originally anticipated. Staff is
requesting Council reject these bids and allow staff the flexibility to re- advertise for bids next
year.
Funding for the project is proposed from the water utility fund. The property owners along W.
78th Street are not proposed to be assessed for the project.
Staff designed, bid the project and is planning to complete the construction administration and
inspection in -house saving the City about $45,000 in consultant fees.

on 78th Street from TH 41 west to the Arbor's development.

service area which is currently not looped. During high flow events such as hydrant flushing this area can experience water hammers that can I
e hot water heater valves to open. This can lead to damage in the properties. To eliminate the water hammer problem the best solution is to
the watermain to TH 41.
