Council Report: 2000-76
Approve Design, Order Bids, Lift Station #6 Reconstruction
Proposed Action.
Staff recommends adoption of the following motion: "Move that Council approve Sanitary
Sewer Lift Station #6 Reconstruction design and authorize bids".
Overview.
Lift Station #6 is located on the north side of Excelsior Blvd just west of Blake Road. City
Council approved design ofthis project in March, 1998 for 1999 reconstruction. The project was
moved back one year due to the delay in approval of the preliminary road layout for the
Excelsior Boulevard Phase II reconstruction project. The Excelsior Blvd, Phase II preliminary
layout has been approved and lift station #6 design is now complete. Staff requests design
approval and authority to advertise for bids.

Analysis of Issues
· Project cost/funding:
The engineers opinion of probable construction cost is $197,000 plus an estimated $40,000 for
city furnished equipment. The cost is well above the CIP amount because staff has simply
carried forward the same project amount since the project first appeared in the CIP in 1995.
Also, the current project includes a control system upgrade to be compatible with the new
SCADA utilities radio control & alarm system. The above cost includes a 10% construction
contingency. The sanitary sewer fund has a strong working capital balance and a healthy 5-year
projection showing increasing capital balances - see attached capital projection report.
. Project Scope:
This project will replace the existing deteriorated wet welVdry well lift station with a City
standard wet well lift station. The new wet well will be located behind the Excelsior Blvd street
and sidewalk. The current lift station is located under the road pavement. Besides a new wet
well, new pumps and a new above-ground control system will be installed. In addition, the new
lift station will discharge into an existing sanitary sewer flowing west to the large trunk sewer
running north along the east side of Hwy 169 to the Metropolitan Council Environmental
Services lift station near Lake Street and Blake Road. This change reduces the flow going to
City-owned lift station #5 (located on the south side of Excelsior Blvd adjacent to Meadowbrook
golf course).
· Project Impact
There should be no sanitary sewer impact to customers connected to this lift station as the project
requires bypass pumping during construction.
The construction area extends both behind the curb on the north side of Excelsior Blvd and
within the traffic lanes of Excelsior Blvd. Therefore, there will be construction impact to both
the traveling public and to the Hopkins Commerce Center businesses whose storefronts face
Excelsior Blvd.
There is a 133' long temporary construction easement area along the north side of Excelsior Blvd
for the operation of construction equipment. A single lane passage will be maintained along the
front of the businesses. One of the business center signs will have to be removed during
construction. The contractor is required to reinstall the sign within one month of removal.
Access to the business center from Excelsior Blvd will be more difficult during construction.
However, the current driveway will remain open for right-in only traffic and Pierce Avenue
.
e
It

access will remain open. The contractor will install temporary signs marking access points to the
business center. City staff has worked closely with the business center owners describing the
project impacts and schedule. The owners approved the temporary construction easement as
well as a slightly expanded permanent easement area.
In the construction area, traffic lanes on Excelsior Blvd will be reduced to a single lane in each
direction. The estimated duration ofthe traffic control is 45 days.
Staff is attempting to limit impacts of the project through construction contract incentive pay and
liquidated damages. The performance period of the contract is 45 days. Of course, the
contractor will not be charged for days lost due to weather or other factors outside his control.
The contract includes incentive pay for early completion. If the contractor completes the work in
less than 45 days, he will be paid $500 for each day up to a maximum of$7,500 (15 days).
Conversely, the City will have a contractual right to impose up to $2,000 per day if the
contractor exceeds the 45 day construction schedule.
