RE: Proposed Amendment No. 2
Contract No. 1900318(SCN-0000424)

Vendor: Arcadis of Michigan, LLC

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. 1900318(SCN-0000424, “2019 Task Order Engineering Services” with various vendors, at an increased cost of $1,000,000.00 for a total cost not to exceed $14,000,000.00 and an increased duration of 1,796 days for a total contract duration of 4,716 days; and authorizes the CEO to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND
The GLWA Board of Directors at its meeting on August 27, 2025, awarded a new set of vendors under the 2025 Task Order Engineering Services (TOES) contract. However, there are existing tasks on the 2019 TOES contract that are in various stages of design, construction assistance, and closeout that need to be fully supported until those projects are completed through design and construction. The intent of this Proposed Amendment No. 2 is to extend the contract end date of TOES consultants’ contracts with active tasks to the same final end date that coincides with the date we expect the last project to be completed (construction of a TOES design task). As individual consultants’ projects are completed, we will close those individual contracts out earlier if possible. No new tasks have been created under the 2019 TOES contract since the award of the 2025 TOES contract.
JUSTIFICATION
This Proposed Amendment No. 2 will extend the contract period by five (5) years, to facilitate proper completion of design, construction assistance, and closeout for approximately 18 tasks. This date is anticipated far enough to support potential changes in construction contracts, supply chain delays, or unforeseen conditions such that we do not anticipate another amendment extending this contract longer to continue said support (construction services) to see all tasks to final completion. This proposed amendment also increases the financial capacity of this contract to account for any potential or unforeseen cost changes throughout the revised contract duration related to existing tasks.
