Acoustic Assessment & GIS Mapping of Wastewater Collection System

The City of Gunnison, Colorado, is seeking a qualified contractor to conduct a comprehensive acoustic assessment of its wastewater collection system through Request for Proposals (RFP No. 25-05). The project objectives include evaluating sewer line conditions, categorizing pipe statuses, and integrating findings into the city's ESRI GIS mapping system. Specific scope of work encompasses acoustic evaluations using ASTM F3220 standards, manhole inspections with laser invert depth retrieval, and survey-grade manhole rim elevations. The proposal evaluation will utilize a 100-point scoring system, with points allocated across five criteria: Letter of Interest (pass/fail), Inspector Qualifications & Experience (25 points), Related Project Experience (40 points), Local Availability (15 points), and Price Proposal (20 points). Key deadlines include questions accepted until April 8, 2025, with proposals due on April 15, 2025, at 2:00 PM MDT. The project timeline targets substantial completion by October 24, 2025, with final payment due by October 31, 2025. Proposals must be submitted electronically through the Rocky Mountain E-Purchasing System (RMEPS), with a 10-page limit for the technical proposal.

The City encourages submissions from disadvantaged, minority, and women-owned consultants, promoting diversity in potential contractors. The contract will be awarded to the respondent with the highest total score, determined by combining technical and price proposal points, with the lowest-priced proposal receiving the maximum 20 points for pricing. While no specific budget range is explicitly stated, the contract requires comprehensive insurance coverage, including worker's compensation, general liability, and automobile liability insurance. The proposed agreement stipulates that payments will be made within 30 business days of invoice submission, with the final installment contingent upon delivery of the final report. Contractors must commit specific personnel to the project, with restrictions on personnel substitutions without city authorization. The contract also includes provisions for immigration compliance, independent contractor status, and adherence to Colorado state laws. Integration with the existing ESRI GIS mapping system is a critical component of the project deliverables.
