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. 1803483 Proposed Change Order No. 3 “Roof Replacement at Various Water Facilities” with Schrieber Corporation, with no increase in cost for a total cost not to exceed $3,208,489.32, and an increase in duration of 169 days for a total duration of 485 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
A comprehensive condition assessment of water pumping station, sewage lift station and water treatment plant building roofs were completed by Testing Engineers and Consultants (TEC) in 2016 under GLWA Contract No. CS-1674. A total of 268 individual roofs measuring nearly 1.7 million square feet were assessed at the 19 water pumping stations, 11 sewage lift stations and 5 water treatment plants.
Roof conditions were lumped into 1 of 4 categories:
Category 1 includes those roofs that have failed and require immediate replacement.
Category 2 includes those roofs that should be replaced within the next 5 years.
Category 3 includes those roofs that are in fair condition with a projected remaining service life of 6 to 10 years.
Category 4 includes those roofs that are in good to excellent condition with a remaining service life greater than 11 years.
A recently completed contract, GLWA Contract No. DB-093, replaced the 1930 Filter Building roof at the Springwells Water Treatment Plant, which was a Category 1 condition roof. Contract No. 1803483 is replacing the remaining Category 1 condition roofs along with Category 2 condition roofs. The roofs being replaced under this contract include the following:
1. Franklin Water Pumping Station
2. Orion Water Pumping Station
3. Conner Sewage Lift Station
4. Water Works Park Water Treatment Plant High-Lift Pumping Station
5. Water Works Park Water Treatment Plant Raw Water Booster Station
6. Springwells Water Treatment Plant Turbine House
7. Springwells Water Treatment Plant Machine Shop
Change Order No. 2 included two (2) additional roofs at Imlay Pumping Station, including the Variable Frequency Drive Room and Electrical Switchgear Room.
JUSTIFICATION
This proposed Change Order No. 3 to Contract No. 1803483 adds 169 days to the contract completion time. There is no change in the contract amount associated with this proposed change order. Additional time is needed for the Contractor to complete the work of the contract as a result of the COVID-19 pandemic and also provides GLWA the required time for contract closeout.
