Town of Apple Valley- Geophysical Survey and Subsurface Mapping

The Town of Apple Valley, Utah, requests competitive proposals from qualified firms to perform a noninvasive or minimally invasive geophysical investigation and subsurface mapping program supporting selection of a future municipal groundwater production-well site. The consultant will integrate available hydrogeologic information with field measurements, interpret subsurface conditions, evaluate uncertainty, and recommend and rank target areas for additional investigation and potential drilling.

This project is anticipated to receive EPA Community Grant funding. [...] This is a performance-based solicitation. The Town does not require or prefer any particular technology.

The selected consultant shall provide the following tasks. Offerors may recommend refinements that improve technical defensibility, cost effectiveness, or grant compliance, but must clearly identify assumptions and optional work.

• Task 1 Project Management and Compliance: Conduct kickoff and coordination meetings with the Town, Town engineer, EPA representatives when requested, property owners, and other authorized parties. [...] Test-well drilling and construction are outside this solicitation.
• Task 2 Existing Data and Desktop Review: Compile and review available geologic, hydrogeologic, topographic, well-log, water-level, water-quality, pumping, aerial, remote-sensing, land-ownership, utility, and prior-study information.
• Task 3 Survey Design and Work Plan: Propose one or more scientifically supportable geophysical methods suited to expected depth, geology, terrain, access, cultural noise, project budget, and decision needs.
• Task 4 Field Investigation: Mobilize qualified personnel and properly calibrated equipment; verify access and utility-clearance requirements; conduct daily safety and quality briefings.
• Task 5 Processing Interpretation and Integration: Process data using documented, reproducible procedures and appropriate corrections, filters, inversions, uncertainty analysis, sensitivity analysis, and independent quality review.
• Task 6 Target Ranking and Recommendations: Recommend and rank at least three candidate target areas when supported by the evidence, or explain why fewer targets are technically defensible.
• Task 7 Reports Data and Presentations: Submit draft and final technical reports suitable for EPA, Town Council, Town engineer, drilling consultants, auditors, and future design teams. [...] Provide GIS-ready shapefiles or geodatabases, coordinate system metadata, raw and processed datasets, model inputs and outputs where transferable, field logs, photographs, maps, and editable source files.

Submit one searchable technical proposal PDF and one separate cost proposal PDF. The technical proposal body may not exceed 25 single-sided pages, excluding cover, one-page letter, dividers, resumes, project sheets, required forms, and insurance evidence. Use readable type no smaller than 10 point. Do not place cost information in the technical file.

Proposals are due 11/9/2026 by 5:00PM Mountain Time, electronically to Michelle Kinney at mkinney@applevalleyut.gov.

Technical factors total 85 points and cost totals 15 points. Award is subject to Town authorization, applicable law, responsibility verification, available funding, and execution of an acceptable contract. No work begins without a Town notice to proceed.

The final contract will establish a not-to-exceed amount. Commercial general liability, automobile, workers' compensation, employer's liability, and professional liability or errors-and-omissions insurance appropriate to the work, with limits finalized before posting or award.
