(Stantec) for $2,300,000.00; Spalding DeDecker Associates, Inc. for $2,000,000.00; OHM Advisors (OHM) for $1,300,000.00; and Wade Trim Associates Inc.

Memorandum
Attached for your review and consideration is a resolution approving Professional Services Agreements with Stantec Consulting Michigan, Inc. (Stantec) for $2,300,000.00; Spalding DeDecker Associates, Inc. for $2,000,000.00; OHM Advisors (OHM) for $1,300,000.00; and Wade Trim Associates Inc. (Wade Trim) for $1,300,000.00 for Construction Inspection Services.
The professional services agreements are set up as three-year contracts to provide year-to-year continuity for these services. The dollar amounts listed for each agreement are the maximum contract values for the three-year period. The contracts are set up such that the awarded firms may adjust their unit prices annually, based on the Consumer Price Index. This resolution authorizes the City Administrator to approve such amendments that do not increase the total value of the contracts.
The Engineering Unit provides inspection for the construction of a variety of private development and capital improvement projects managed by the Engineering Unit that are within the City’s right-of-way. The construction inspectors’ tasks include oversight of contractor activities, enforcement of construction standards, and measurement of pay item quantities. These tasks are critical to the success of any construction project.
Due to the fluctuation of construction activity throughout the year (lighter during winter months and heavier during the warmer ones), the level of staffing within the Engineering Unit must often be supplemented in the spring/summer/fall construction season to provide sufficient inspection for all of the planned and anticipated projects. Based on the number of planned capital projects and the anticipated volume of private development work, Engineering staff expects a need for additional inspectors to adequately cover all the construction activities.
In October of 2024, the City received proposals for construction inspection services in response to RFP No. 24-52 from six firms. A staff selection committee reviewed the proposals and determined the firms most qualified for the work according to following criteria:
• Professional Qualifications (20%)
• Past Performance (30%)
• Proposed Work Plan (30%)
• Fee Proposal (20%)
Staff ranked the responding firms in the following order:
1. Stantec Consulting Michigan, Inc.
2. Spalding DeDecker Associates, Inc.
3. OHM Advisors
4. Wade Trim Associates Inc.
5. Alfred Benesch & Company
6. TYME Consulting Engineers
The selection committee decided that the top four firms were qualified to perform the work and found their fee proposals to be reasonably comparable. To provide flexibility and adequate staffing to cover all the City’s construction projects during the peak of the construction season, staff is recommending to award contracts to these four firms.
These consultant services will be used on an as-needed basis only during the 2025, 2026 and 2027 construction seasons, when additional support is needed to supplement existing Engineering staff. Since these are as-needed contracts, no minimum amount of work is guaranteed for any of the firms. If Staff is not satisfied with the performance of any firm, that firm will not be selected for additional assignments.
All four firms are in compliance with the requirements of the City’s Non-Discrimination and Living Wage ordinances.
Budget/Fiscal Impact: The services provided through these professional services agreements will be paid for within approved project budgets and annual operating budgets, as appropriate. Costs for inspection on private development projects are recouped through fees charged to developers.
