The scope includes three tasks: pre-field preparation and background research, fieldwork involving debris sorting and targeted excavation, and preparation of a technical report for submission to the State Historic Preservation Office, which must include findings on historical significance and NRHP eligibility, along with geospatial data and digital imagery. All work must adhere to March ARB Spatial Data Submittal Standards and HAZWOPER certification requirements for personnel handling potentially contaminated soil. Deliverables must be submitted in specified electronic formats, with hard and digital copies provided as outlined, and performance is restricted to a narrow window from June 8 to June 26, 2026. The contract is a firm fixed price, set aside exclusively for small businesses under NAICS code 541620 with a size standard of $28 million, and incorporates multiple FAR and DFARS clauses covering cybersecurity, whistleblower rights, contractor reporting, electronic invoicing via WAWF, and government inspection rights throughout the performance period. Base access requires credentialing, compliance with security protocols, and adherence to safety and remediation plans for the disturbed site.
