ARCHITECTURAL AND ENGINEERING DESIGN SERVICES
Solicitation # 26-R02
The Stanislaus Council of Governments (StanCOG) is soliciting proposals for architectural and engineering design services to convert a former bank teller area at 1407 I Street in Modesto, California, into a Policy Board meeting chamber and remodel associated office spaces. The project aims to create a boardroom capable of accommodating a 16-member board, agency staff, and the public, as the agency must vacate its current leased meeting space by November 2026. The scope of work encompasses the full design lifecycle, including programming, existing conditions verification, code analysis with the City of Modesto, schematic design with at least two options, construction documents, permitting, and construction administration. A critical requirement is the development of a phasing plan to ensure the building remains occupied by staff during construction. Proposals are evaluated based on qualifications, with scoring weighted across understanding and approach, firm experience, personnel, scope of work, and interviews. Cost proposals are submitted separately and are not scored during the initial ranking process. The selected consultant must comply with California prevailing wage laws, ADA standards, and federal requirements, including 2 CFR Part 200 and FTA Circular 42201.G. Required deliverables include base plans, renderings, and signed and stamped construction documents provided in both PDF and native editable formats such as Revit or AutoCAD. The procurement process includes several addenda, with the final response deadline established as November 13, 2026.
