RE: Proposed Amendment No. 4
Contract No.: GLWA-CS-060
Study/Design of an Upgraded Sludge Conveyance System and Lighting Improvements at the Detroit Wastewater Treatment Plant
Vendor: Black & Veatch Ltd. of Michigan
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, Proposed Amendment No. 4, “Study/Design of an 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 for an increased duration of 215 days, for a total duration of 2,834 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
Black & Veatch Limited of Michigan was awarded the original contract to provide, study, design, and construction assistance to GLWA with a start work date of April 29, 2016. 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.
On April 14, 2018, Black & Veatch was granted Amendment No. 1 for additional design and construction assistance activities.
On May 26, 2021, Black & Veatch was granted Amendment No. 2 to extend the contract time from June 30, 2021, to June 30, 2022, 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 Amendment No. 3 to extend the contract time from July 1, 2022, to June 30, 2023, due to equipment performance issues that were delaying completion of the related construction contract, GLWA-CON-197.
JUSTIFICATION
Construction Amendment No. 3 was issued on February 3, 2023, to Weiss Construction Company for the associated construction contract (GLWA-CON-197) extending the construction contract times to March 30, 2023, for Substantial Completion and September 29, 2023, for final completion. Because of ongoing performance issues associated with some of the new equipment and other issues, GLWA-CON-197 has not yet achieved substantial completion and is not expected to achieve final completion by September 29, 2023.
Additionally, repeated strainer backwash piping leaks and conveyor drip pan spray issues have necessitated design revisions prolonging construction due to long-lead material deliveries and subsequent installation time.
GLWA Wastewater Engineering has assessed that a contract extension is needed for the current contract time under GLWA-CS-060. The extended final completion date will allow for Black & Veatch to complete the remaining contractual construction administration services to GLWA. No additional contract funding is required as a result of this time extension.
