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 “Design Build Roof Replacement Various Water Facilities” with Schreiber Corporation, at a cost not to exceed $3,031,089.32 and an increased duration of 131 days for a total contract duration of 311 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 was 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 one of four 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 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 (WTP), 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:
Franklin Water Pumping Station Category 1
Orion Water Pumping Station Category 1
Conner Sewage Lift Station Category 1
Water Works Park WTP High-Lift Pumping Station Category 1
Water Works Park WTP Raw Water Booster Station Category 2
Springwells WTP Turbine House Category 2
Springwells WTP Machine Shop Category 2
JUSTIFICATION
This proposed Change Order No. 1 to Contract No. 1803483 adds 131 days to the contract time. There is no change in the contract amount associated with this proposed change order. Adding time to the contract will mitigate risk related to contractor safety and temperature dependent material properties associated with the installation of roofing materials.
