BACKGROUND
Black & Veatch Ltd. of Michigan was awarded the original contract for consultant services 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 was needed.
On April 14, 2018, Black & Veatch was granted a contract Change Order No. 1 in an amount of $96,404.00 for additional design and construction assistance activities, which increased the total contract value to $2,086,404.00.
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.
On June 22, 2022, 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.
On July 31, 2023, Black & Veatch was granted a contract Change Order No. 4 to extend the contract time due to ongoing equipment performance issues and piping failures that were delaying completion of the related construction contract, GLWA-CON-197.
JUSTIFICATION
On October 23, 2023, construction Change Order No. 4 was issued to Weiss Construction Co. LLC the associated construction contract (GLWA-CON-197) extending the contract time for Final Completion to July 16, 2024. The extension of time was issued for the contractor to correct excessive sludge spillage from the new conveyors and replace leaking strainer backwash piping.
The extension of time is needed for alignment of the design contract with the construction contract. Furthermore, upon completion of the construction contract, the designer, Black & Veatch, will need additional time to prepare final O&M manuals and as-built record drawings, among other services.
