The primary objective of this project is to establish an accurate, reliable sanitary model to evaluate existing system capacities, assess sewer capacity for future development, and guide long-term sanitary sewer maintenance, capital improvements, and master planning.
DISCUSSION:
On May 5, 2026, the Water Utilities Department issued Request for Proposals (RFP) 26-102 for professional engineering services to develop an InfoWorks ICM hydraulic model of the City’s sanitary collection system. Proposals were received from the following vendors:

Baxter & Woodman, Inc. |
Jacobs Engineering |
|
Burns and McDonnell |
Crawford Murphy and Tilly |
|
Michael Baker International |
RJN Group |
|

Kimley-Horn and Associates, Inc. |
A selection team comprised of staff from the Water Utilities evaluated the proposals, which were scored based upon criteria set forth in the RFP:
1. Capability, Capacity and Qualifications of the Proposer (40%)
2. Suitability and Quality of the Approach/Methodology (45%)
3. Milestones and Deliverables (15%)
Following the review and scoring of the proposals, the selection committee invited the two highest-scoring consultants-Jacobs Engineering and the RJN Group-to attend an interview. Upon completion of the interviews, the committee re-evaluated and rescored both firms. Based on the final evaluation, Jacobs Engineering received the highest overall score and is recommended for the contract award. The table below summarizes the final qualification scores:
