Adopt Resolution #24-098 Approving Proposal for Lift Station No. 1 Permanent Generator Design and Construction Services

Purpose:
The purpose of this case is to adopt Resolution #24-098 approving a proposal from Bolton & Menk, Inc. to provide design, bidding, and construction related services for City Maintenance Project #24-56, Lift Station No. 1 Rehabilitation and Generator Installation. 

Background:
The 2024 – 2033 Capital Improvement Program includes proposed project #24-SEW-002, Lift Station No. 1 Rehab and Generator, proposed for construction in 2025 at an estimated cost of $175,000.

This project proposes to rehabilitate sanitary sewer Lift Station No. 1 by replacing the original base elbows and forcemain, upsizing the pumps, and installing a permanent emergency power supply generator on site.  This work will serve to replace deteriorating pipes and fittings, to accommodate increased sewage flowrates that have occurred since the lift station was constructed in 1990, and to prevent sewage from backing up into businesses and residences served by this and other lift stations during major power outages.
 
During power outages, staff tows a portable generator on a trailer to this and other lift stations that don’t have permanent generators.  Staff pumps each station down, then disconnects the generator and moves to the next station, and repeats the process until power is restored.  However, due to the constant and heavy sewage flowrates processed through this station, staff would not have the ability to disconnect the portable generator in the event of a long-term power outage, leaving other lift stations without power and possibly backing sewage up into neighboring homes and businesses.  

City Staff received the attached proposal from Bolton & Menk, Inc. in the not-to-exceed amount of $26,400 to design the permanent emergency power supply generator and prepare plans and specifications for rehabilitating the lift station and constructing improvements necessary to accommodate the permanent generator, apply for permits, administer the bid process, and provide construction related services.  

Notifications are not required for this case.
 
Upon adoption of Resolution #24-098, Bolton & Menk, Inc. will prepare the required plans and specifications for this project.  Staff will then request Council approval of plans and specifications and authorization to advertise bids in the Anoka County Union Herald on two consecutive Fridays.  Bids would then be publicly opened and tabulated and presented to the City Council for acceptance and award of a construction contract to the lowest responsible bidder at the following regular City Council meeting.  

Observations:
List Station No. 1 is not the largest list station in Ramsey but it is the busiest, as well as the oldest, and it averages 60 starts per day.  The purpose of this project is to improve the reliability and productivity of this lift station.   
 
Staff will also investigate whether a sound study is required, similar to the study completed for Pump House No. 2 before a permanent generator was purchased for that site.
 
Staff will also explore what SCADA changes are needed, if any.
 
Staff will also determine required pump sizes due to current and anticipated flowrates, which will then be used to determine the required generator size. 

Alternatives:
Alternative 1:  Motion to adopt Resolution #24-098 approving Bolton & Menk, Inc.’s proposal to provide design, bidding, and construction related services for City Maintenance Project #24-56, Lift Station No. 1 Rehabilitation and Generator Installation.  

Attached is the adopted 2024 – 2033 CIP sheet for project #24-SEW-002, Lift Station No. 1 Rehab and Generator, proposed for construction in 2025 at an estimated cost of $175,000.
 
Funding for this project, including costs for contracted design and construction related services, is proposed to come from sanitary sewer enterprise funds.   

Staff recommends approving alternative #1 for reasons noted herein.     

Motion to adopt Resolution #24-098 approving Bolton & Menk, Inc.’s proposal to provide design, bidding, and construction related services for City Maintenance Project #24-56, Lift Station No. 1 Rehabilitation and Generator Installation.
