RE: Contract No. 2201316
Reservoir Rehabilitation Construction Phase II
Vendor: LGC Global, Inc.
MOTION
Upon recommendation of Cheryl Porter, Chief Operating Officer - Water and Field Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 2201316, “Reservoir Rehabilitation Construction Phase II” with LGC Global, Inc., at a cost not to exceed $35,573,564.00 for a duration of 1,659 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
GLWA operates 30 finished drinking water reservoirs, inspection, repair, and cleaning of the reservoirs on a regular interval and is mandated by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) and performed under GLWA capital improvement maintenance program 170800. As of spring 2023, 10 finished water reservoirs over the last three years were inspected and rehabilitated under Contract Nos. CS-151 and 1900744. The next phase of inspections on 16 reservoirs is being conducted under a separate engineering services contract with Brown and Caldwell, LLC (i.e., Contract No. 2100236).
The design specifications and drawings that detail the required restoration and rehabilitation work have been prepared under Contract No. 2100236. The proposed construction Contract No. 2201316 with LGC Global, Inc. will include inspection and rehabilitation work on 16 finished drinking water reservoirs. GLWA plans to inspect and rehabilitate four reservoirs each fiscal year (FY) - FY2024, FY2025, FY2026, FY2027.
The reservoirs are located at the following GLWA facilities: Water Works Park Water Treatment Plant (WTP) (3 reservoirs), Northeast WTP (2 reservoirs), Lake Huron WTP
(1 reservoir), East Side Station (1 reservoir), Wick Station (1 reservoir), Haggerty Station (1 reservoir), Schoolcraft Station (1 reservoir), Adams Road Station (1 reservoir), Joy Road Station (2 reservoirs), North Service Center (2 reservoirs), and Michigan Avenue Station (1 reservoir).
The rehabilitation work includes concrete repairs, expansion joint replacement, hatch and ladder repair, air vent repair and air vent screen replacement, roofing membrane repair and replacement, reservoir overflow rehabilitation, in-reservoir piping repairs/coating, inlet and outlet control valve vault rehabilitation, underdrain inspections, underdrain pump replacement, painting of carbon steel components, electrical controls and receptacle installation and repair, and site work improvements. The proposed Contract No. 2201316 contains lump sum work and unit price work. Unit price work will be paid out based on actual quantities installed as identified by the Engineer.
JUSTIFICATION
Finished water reservoirs must be inspected on regular intervals to comply with EGLE regulatory requirements. Furthermore, inspection and rehabilitation of GLWA’s finished water reservoirs on a regular schedule is the preferred approach to proactively maintain and ensure reservoir integrity and safe finished drinking water quality.
