The City of Oklahoma City and Oklahoma City Water Utilities Trust are soliciting professional engineering services for a comprehensive Sewer Model Calibration project (SC-1156) to improve their existing wastewater collection system infrastructure. The procurement seeks a consulting firm to conduct detailed calibration of the current InfoWorks ICM sewer model, which encompasses over 3,100 miles of gravity mains, 50 miles of force mains, 4 wastewater treatment plants, and 75 lift stations. Key project deliverables include field investigations, data gathering, model calibration using sewer meters and rain gauge data, system flow and capacity reevaluation, lift station assessment, overflow prediction, and preparation of 5, 10, and 15-year improvement reports. Interested engineering firms must submit a detailed Letter of Interest through the electronic bidding system at https://www.bidnetdirect.com/ by 5:00 p.m. on July 9, 2025, with a complete Calibration Model Report due within 365 days of City/Trust approval of the Notice to Proceed. Submission requirements include a 254 Form, a 50-page maximum narrative demonstrating similar project experience, project team composition, and team member availability, along with a contact name and email address. No specific set-aside designations or restrictions for disadvantaged enterprises are explicitly mentioned in the procurement documents. Potential respondents must execute a non-disclosure agreement to access additional project information, including GIS data of the existing sewer system, the current InfoWorks ICM Sewer model, and as-built information. The project does not indicate an incumbent vendor, but requires integration with the city's existing enterprise GIS database and ArcGIS Pro version 3.X. While the estimated project cost is not definitively stated, no construction is anticipated in this initial contract, and the City reserves the right to negotiate the Scope of Work, Compensation, and Additional Services. The procurement allows for potential future expansion, with the current focus on model calibration and system analysis to improve the reliability of wastewater collection system modeling and planning. All submissions will be subject to the Oklahoma Open Records Act, and consultants must follow specific confidentiality guidelines if they believe any part of their submission should be kept confidential.
