RE: Requisition No. REQ-0007283/SCN-0000800
Emergency Construction Contract for Lake Huron Water Treatment Plant High Lift Building Column Repairs
Vendor: Pullman SST, Inc.
Status: Amendment/Change Order
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 Requisition No. REQ-0007283/SCN-0000800, Proposed Change Order No. 1, “Emergency Construction Contract for Lake Huron Water Treatment Plant High Lift Building Column Repairs” with Pullman SST, Inc., with no increase in cost for a total cost not to exceed $1,565,950.00 and an increased duration of 182 days for a total duration of 322 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The Lake Huron Water Treatment Plant High Lift Building is constructed with post tensioning cables that are anchored to metal plates that are encased in concrete in the exterior columns. It was observed that the concrete caps were in deteriorated condition and had started to expose metal plates to the elements. A repair detail to replace the concrete caps was developed through Contract No. 1803769 and construction was started through Contract No. 1803990. Work was stopped during demolition when concrete degradation was discovered behind the bearing plates. A revised design was developed through Contract No. 1803769. The changed scope was not incorporated in Contract No. 1803990 due to the bonding company’s refusal to accept the change. There is an urgent need to complete repairs to avoid losing tension on the beams that would be a safety, structural and process risk and necessitate much more expensive repairs.
Due to the unseasonably cold weather, the Contractor could not perform repairs within the original schedule and took provisions to temporarily protect exposed columns. Additionally, there have been supply chain delays for the metal flashing.
JUSTIFICATION
The no-cost 182-day extension to SCN-0000800 is necessary for completion of these critical improvements.
