Tetra Tech, Inc.
MOTION
Upon recommendation of Marqaicha Welch, Purchasing Manager, the Board of Water Commissioners for the City of Detroit, Water and Sewerage Department, authorizes the Director to approve DWSD Contract No. 6004680 (CS-1973) with Tetra Tech of Michigan, P.C. for Drainage Charge Program Support Services with a contract amount not-to-exceed $500,000 and a term of three (3) years. This also authorizes the Director to take such other action as may be necessary to accomplish the intent of this vote.
BACKGROUND / JUSTIFICATION
The proposed contract will provide a wide range of technical/engineering support to the Drainage Team and will replace the most recent contract, which is expiring. With most of the Drainage Charge related work being performed inhouse by the Drainage Team, there still exists an ongoing need of the consulting support/expertise for the Drainage Charge Program.
Responsibilities of the Contractor under this contract include tasks such as drainage charge assessment, green credit evaluations, and additional tasks as described in the RFP’s Scope of Work. In addition, the new impervious area data set residential parcels is scheduled to be launched in July 2022 by DWSD Billing and a surge in drainage charge adjustment requests from affected customers is anticipated. The Drainage Team is yet to be fully staffed, which also necessitates the need of additional support from a consultant for review of customer requests.
The current contract for Drainage Charge Program Support expires on July 1, 2023, but the fund is almost exhausted. A replacement contract is necessary to continue providing support to the Drainage Team.
PROCUREMENT METHOD
DWSD published Request for Proposals (RFP) #494156 for Drainage Charge Program Support Services on the MITN Bidnet website for 33 calendar days (4/28/22 - 5/31/22). Requisition #494156 submitted by the Permitting & Stormwater Management Group was fully approved on 1/4/22.
Two (2) proposals were received:
|
DLZ Michigan, Inc. Tetra Tech of Michigan, P.C. |
|
|
|
|
The Proposals were first evaluated for responsiveness by the DWSD Procurement Department. DLZ Michigan, Inc. and Tetra Tech of Michigan, P.C. were determined to be responsive.
The Evaluation Committee was comprised of an Engineering Manager, the Permit Manager, and a GIS Analyst. Evaluations were based on the following criteria:
• Ability to perform work
• Work plan & organization
• Staff Experience
• Pricing
• Local Economic Development
• Bona-fide Detroit Resident Participation
Each voting member of the Evaluation Committee independently reviewed, evaluated, and scored the two (2) responsive proposals based on the criteria listed above (pricing info was withheld until the technical portion was scored). Procurement took the scores and tallied up the rankings based on the scores. Once that was finalized, the pricing information was opened, and the Proposers were again ranked from lowest to highest based on price. Procurement then determined the highest ranked proposer based on the final scores.

The Evaluation Committee and Procurement recommended the highest-ranked responsive & responsible Proposer, Tetra Tech of Michigan, P.C., enter negotiations for contract award. Negotiations were successful.
Tetra Tech’s clearances expire on 4/18/23 and the formal contract document has been routed to Tetra Tech for review and signature.
