RE: Proposed Change Order No. 7
Contract No. GLWA-CS-060/SCN-0000212
Study/Design of the Upgraded Sludge Conveyance System and Lighting Improvements at the Detroit Wastewater Treatment Plant
Vendor: Black & Veatch Ltd. Of Michigan
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. GLWA-CS-060/SCN-0000212, Proposed Change Order No. 7 “Study/Design of the Upgraded Sludge Conveyance System and Lighting Improvements at the Detroit Wastewater Treatment Plant” with Black & Veatch Ltd. Of Michigan, with no increase in cost for a total cost not to exceed $2,086,404.00 and an increased in duration of 180 days for a total duration of 3,745 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The main objective of the Black & Veatch consultant services contract was to restore sludge conveyance capacity lost due to the March 2016 fire damage while providing improved sludge conveyance from each dewatering facility to improve operations and minimize future risks. To achieve that goal, an evaluation study and design and construction assistance were needed.
On April 14, 2018, Black & Veatch was granted a contract Change Order No. 1 for additional design and construction assistance activities. The contract duration also was extended via Change Order No. 1.
On May 26, 2021, Black & Veatch was granted a contract Change Order No. 2 to extend the contract time due to delays in the related construction contract, GLWA-CON-197, caused by unforeseen conditions and the COVID-19 pandemic.
Black & Veatch was granted a contract Change Order No. 3 to extend the contract time due to equipment performance issues that were delaying completion of the related construction contract, GLWA-CON-197.
Black & Veatch was granted a contract Change Order No. 4 to extend the contract time from June 30, 2023, to January 31, 2024, due to ongoing performance issues associated with some of the new equipment and other issues that necessitated design revisions and therefore delay the completion of the related construction contract, GLWA-CON-197.
Black & Veatch was granted a contract Change Order No. 5 to extend the contract time due to ongoing performance issues with some of the new equipment and other issues that necessitated design revisions.
Black & Veatch was granted a contract Change Order No. 6 to extend the contract time due to the ongoing performance issues in the sludge conveyance system which delayed the completion of the related construction contract GLWA-CON-197 and therefore necessitated Black & Veatch’s continued engineering services.
The investigation efforts regarding the conveyance system failures are still ongoing, and a time extension of this consultant services contract is required for Black & Veatch to provide uninterrupted professional engineering services in support of GLWA-CON-197.
JUSTIFICATION
A time extension of the current consultant services contract (GLWA-CS-060) with Black & Veatch is necessary due to ongoing performance issues with the conveyance system. Extending Contract GLWA-CS-060 will ensure uninterrupted engineering services in support of the associated construction contract, GLWA-CON-197.
In light of the above, GLWA Wastewater Operations recommends extending the Final Completion date, with no increase in the contract amount.
