Title
Resolution to Approve a Construction Contract with Insituform Technologies USA, LLC for the High Level Trunkline Sanitary Sewer Rehabilitation Phase 2 Project ($4,242,055.60)
Memorandum
Attached for your review and approval, please find a resolution that awards a construction contract to Insituform Technologies USA, LLC for the High Level Trunkline Sanitary Sewer Rehabilitation Phase 2 Project (RFP 22-70).
This project consists of lining approximately 4,300 feet of 30-inch sanitary sewer and 1,980 feet of 15-inch sanitary sewer beginning at Jefferson Street near Ashley Street and extending northwest along the railroad right-of-way to First Street then north along First Street, terminating at Miller Avenue. An additional section of lining will also occur starting at Hoover Avenue near Division and extend east along Hoover Avenue, south along State Street to Arch Street, and terminate at White Street. In addition, the project will line fifteen sanitary sewer manholes to aid in limiting stormwater infiltration into the sanitary sewer system. This project includes the remaining footage from the unfinished first phase of the High Level Trunkline Sanitary Sewer Rehabilitation Project. The construction of the project is scheduled for January through April 2023.
Lining is a trenchless technology which enables the pipe to be repaired without disturbing the surface above, although in this instance some disturbance may need to occur in order to install temporary bypass pipes to convey the sewer flow while the mains are lined. The lining of these sanitary sewers is critical to extending the service life of these pipes.
Engineering staff supervised the creation of plans and contract documents and bid the project through the City’s Procurement Unit. On October 20, 2022 two proposals were received for this work; however, one proposal was deemed not responsive due to the lack of a bid bond. A selection committee comprised of Public Services staff reviewed the remaining proposal from Insituform Technologies USA, LLC based on the criteria provided in ORD-21-41, adopted by Council on January 3, 2022:
• Qualifications, Experience, & Accountability (20%)
• Workplace Safety (20%)
• Workforce Development (20%)
• Social Equity & Sustainability (20%)
• Schedule of Pricing/Cost (20%)
After reviewing and scoring the proposal, staff recommends the project be awarded to Insituform Technologies USA, LLC.
Insituform Technologies USA, LLC. complies with the City’s Non-Discrimination and Living Wage ordinances.
Budget/Fiscal Impact: The City of Ann Arbor Capital Improvements Plan (CIP) includes the High Level Trunkline Sanitary Sewer Rehabilitation Ph. 2 (UT-SN-22-11).
