RE: Proposed Change Order No. 1
Contract No. 2201068/SCN-0000420
Springwells Water Treatment Plant Medium Voltage Electrical System Replacement
Vendor: Clark Construction Company
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 Contract No. 2201068/SCN-0000420, Proposed Change Order No. 1, “Springwells Water Treatment Plant Medium Voltage Electrical System Replacement” with Clark Construction Company, at an increased cost of $3,840,959.53 for a total cost not to exceed $68,298,819.53 and an increased duration of 261 days for a total duration of 2,021 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
Contract No. 2201068 was executed on December 14, 2022, with a total value of $64,457,860.00 with Clark Construction Company. The scope includes installation of new medium voltage 15-kilovolt rated switchgear, connection to the three (3) existing DTE Energy electrical feeds and the eight (8) Low Lift and 16 High Lift pumping units, and demolition of existing circa 1930s switchgear and wiring at the Springwells Water Treatment Plant. This proposed Change Order No. 1 would extend final completion from November 4, 2027, to July 22, 2028, and add an additional $3,840,959.53 to the Contract Price. During review of the new medium voltage switchgear shop drawings by DTE Energy, multiple changes were requested by DTE related to the sequence of operations for the switchgear, relays, and interlocks. The changes required additional design and manufacturing time by the equipment supplier and additional field wiring by the contractor. Request for Quotation (RFQ) No. 8 was issued to Clark Construction to price the wiring changes and the contract delay. Additional contract time is necessary for the contractor to complete the installation, startup, and commissioning process.
JUSTIFICATION
The implementation of the changes in the switchgear is necessary to complete installation of the new medium voltage switchgear to supply power to the Springwells Water Treatment Plant. DTE Energy will not authorize the connection of the switchgear to their system without the requested changes made. This switchgear replacement is required to be complete before replacement of the Low Lift and High Lift pumping units can proceed under CIP No. 114002.
