The scheduled contract completion date is February 11, 2027.
As of April 17, 2026, the attached list of change orders has been approved.

Item 1: The contract documents specified the installation of a minimum 2.0-inch geopolymer liner within the intercepting sewer. Based on the engineer’s evaluation of the contractor’s design calculations and supporting manufacturer documentation submitted in response to our Request For Information, it was determined that a 1.5-inch liner thickness meets the specified performance requirements and preserves the hydraulic capacity of the existing sewer. This change order includes a credit reflecting the reduction in material, labor, and equipment resulting from the reduction in liner thickness from 2.0 inches to 1.5 inches. The contractor submitted a cost proposal (CO-04) for an extra in the amount of $0.00 and a credit in the amount of $781,802.43, for a net credit in the amount of $781,802.43. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO04 that the Engineering Department would recommend its approval.
Item 2: The contract documents required the contractor to install a GlasGrid Reinforcing Mesh within the intercepting sewer. The contractor notified the engineer that the installation of the geopolymer lining would meet the specified physical property requirements, as outlined in the contract documents, without the need of the reinforcing mesh. As a result, the contractor requested the removal of the GlasGrid installation requirement from the contract. The contractor submitted a cost proposal (CO-08) for an extra in the amount of $0.00 and a credit in the amount of $321,135.70, for a net credit in the amount of $321,135.70. The engineer reviewed the contractor’s proposal, found it to be unacceptable, and countered with the engineer’s estimate of an extra in the amount of $0.00 and a credit in the amount of $386,818.13, for a net credit in the amount of $386,818.13 which the contractor accepted. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO08, that the Engineering Department would recommend its approval.
These change orders are due to circumstances not reasonably foreseeable at the time the contract was signed and is in the best interest of the District.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute these change orders to decrease Contract 20-161-3S in an amount of $1,168,620.56 (-5.82% of the current contract value), from an amount of $20,079,177.33, to an amount not to exceed $18,910,556.77.
Funds will be restored to Account 401-50000-645700.
Requested, Catherine A. O’Connor, Director of Engineering, KMF:LS
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Precious Brady-Davis, Chairperson Committee on Procurement
