RE: Proposed Change Order No. 3
Contract No. 1902224/SCN-0000194
Design Build Contract for the CSO Structural Improvements
Vendor: Pullman SST, Inc.
Status: Amendment/Change Order
MOTION
Upon recommendation of Navid Mehram, Chief Operating Officer - Wastewater Operating Services, the Board of Directors (Board) of the Great Lakes Water Authority (GLWA), authorizes the Chief Executive Officer (CEO) to enter into Contract No. 1902224/SCN-0000194, Change Order No. 3, “Design Build Contract for the CSO Structural Improvements” with Pullman SST, Inc., at an increased cost of $0.00, for a total cost not to exceed $14,905,334.00 and an increased duration of 455 days for a total duration of 1916 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
On August 26, 2020, GLWA awarded Pullman SST, Inc. (Pullman) “Design Build Contract for the CSO Structural Improvements”, Contract No. 1902224 with a start date of January 4, 2021. The purpose of this design build contract is to identify and implement all structural repairs required at the nine Combined Sewer Overflow (CSO) Facilities maintained and operated by GLWA. To date, Pullman has completed all priority repairs with one major task remaining.
Prior to Change Order No. 2, it was noted that the above-ground concrete electrical duct bank on the basin roof, carrying the facility’s electrical feeds, was showing significant concrete spalling and cracks. The engineering team evaluated multiple alternatives to replace or repair this duct bank, and found repair of it establishes a satisfactory remaining useful life. A time extension is needed to complete this repair of the duct bank and also replace the backup generator for the facility.
JUSTIFICATION
Failure to repair the electrical duct bank properly would result in an increased potential for failure of the conduits within the duct bank which could lead to permit violations due to power loss to the facility and could also lead to potential safety risks to GLWA team members, contractors, and others working on the Hubbell-Southfield facility. In addition to making the power feed duct bank more reliable, the emergency generator is at the end of its useful life and will be replaced to ensure power reliability in accordance with 10-state standards.
