UNSPSC 71112300: Seismic services

Services performed that assist to interpret the composition, fluid content, extent and geometry of rocks in the subsurface.

UNSPSC 71112300 Seismic services is a Class code representing specialized technical analysis and interpretation of strong-motion earthquake data collected by seismic instrumentation networks. State and local governments in California and Georgia are currently soliciting under this code for both research-level seismic data interpretation and engineering consulting services that incorporate seismic analysis into infrastructure design and assessment, though the two categories show distinct patterns.

The California Department of Conservation, California Geological Survey dominates recent activity, having issued three consecutive RFPs in May 2026—RFP 1026-001 Strong-Motion Data Interpretation: Lifelines (due June 29, 2026), RFP 1026-002 Strong-Motion Data Interpretation: Ground Response (due June 29, 2026), and RFP 1026-003 Strong-Motion Data Interpretation: Buildings (due June 29, 2026)—each seeking contractor services to interpret and analyze strong-motion data from the California Strong Motion Instrumentation Program to advance seismic design code provisions, seismic analysis procedures, and post-earthquake response capabilities. Each contract carries a maximum award of $100,000, runs through December 31, 2028, and requires a minimum of three years' experience analyzing and applying strong-motion data. A small business preference of five percent and disabled veteran business enterprise incentives of up to five percent apply to all three awards. Beyond California's research-focused procurement, engineering consulting solicitations in Georgia and Florida—including West Basin Municipal Water District's on-call engineering RFP (due July 14, 2026) and Orange County, Florida's continuing engineering services RFP (due February 17, 2026)—occasionally embed seismic or geotechnical analysis within broader civil engineering scopes for water, wastewater, and utility infrastructure projects, though those procurements do not emphasize seismic expertise as a primary differentiator. Geographic activity is concentrated in California for specialized seismic research contracts and dispersed across Georgia and Florida for general infrastructure engineering where seismic analysis may be a component rather than the primary scope.
