NIGP 95630: Historical Studies and Services

NIGP 95630 Historical Studies and Services, an Item code, covers consulting work that state and local governments commission to evaluate, document, preserve, and adaptively reuse historic structures and sites. Recent solicitations show state and local buyers purchasing historical research, architectural and engineering assessment, preservation planning compliant with the Secretary of the Interior's Standards, archaeological and cultural resource monitoring, interpretive planning and content development, and regulatory coordination and permitting support tied to federal, state, and local compliance frameworks such as the California Environmental Quality Act and the Levine Act disclosure requirements. Issuing bodies range across county governments (Bexar County in Texas, San Mateo County in California), cities (Fort Myers and Salem in Oregon), and county departments (San Mateo County Parks Department). Work is performed in-house or through on-call vendor panels, sometimes spanning multiple years with optional renewal periods.

Recent activity is concentrated in Texas, California, and Oregon. Representative opportunities include Bexar County's RFP for historic preservation and design engineering services for Casa Vieja, a historic 1848 residence undergoing rehabilitation within Trueheart Ranch Nature Park (due October 2, 2026); San Mateo County Parks Department's RFP for on-call archaeological and cultural resource assessment, monitoring, and CEQA and permitting services across its 24-park system with a three-year initial term and one optional two-year extension (proposals due March 23, 2026); and the City of Salem, Oregon's RFP for interpretive planning, historical research, and content development services for Fairview Park Phase 1 (due June 26, 2026). San Mateo County's procurement emphasized local business preferences (5 percent for local status, 3 to 5 percent additional for small or micro business status) and required $2 million combined single-limit general liability insurance and $2 million Errors and Omissions professional liability coverage. Contractors on San Mateo's panel must demonstrate a minimum of four years of relevant experience within the last seven years.
