Southern California Advanced Builders, Inc.

Southern California Advanced Builders, Inc., a minority-owned, woman-owned small business based in Banning, California, provides specialized seismic monitoring infrastructure construction, site preparation, and vegetation management services exclusively to the U.S. Geological Survey as a prime contractor. The company operates as a Subchapter S corporation with self-certified small disadvantaged business status, and competes predominantly on total small business set-asides, though individual task orders may carry no set-aside designation when drawn from set-aside-underlying indefinite delivery contracts.

SCAB's capability portfolio centers on earthquake early warning system infrastructure — constructing seismic monitoring stations, installing equipment vaults and solar arrays, performing site preparation with grounding systems and telemetry infrastructure, and conducting vegetation abatement and brush removal around monitoring stations across California, Oregon, and Washington. The company works under two active single-award IDIQs with USGS: a $1.2 million indefinite delivery contract (140G0322D0004) awarded August 2022 through September 2027 for seismic site station construction, and a $1.131 million contract (140G0325D0002) awarded June 2025 through May 2030 for brush removal services. Representative work includes a $666 thousand firm-fixed-price task order (awarded August 2024) for Type B station construction in Northern California, a $475.9 thousand time-and-materials delivery order (awarded October 2025) for brush removal through September 2026, a $437.7 thousand task order (awarded September 2022) for site preparation and infrastructure installation, and a $453.8 thousand definitive contract (awarded October 2021) to install equipment vaults, solar arrays, and drainage systems at fifty-eight seismic station locations. Most recent work includes a $24.4 thousand purchase order (awarded May 2026) to remove and install a CONEX container with electrical power at the USGS Earthquake Science Center in Ridgecrest, California.

Customer concentration is total — USGS's Office of Acquisitions and Grants represents 100% of SCAB's federal award footprint (14 awards, $5.9 million combined potential value). SCAB's top parent vehicles carry four task orders under IDIQ 140G0322D0004 ($1.2 million combined potential value) and two task orders under the vegetation abatement contract ($519 thousand). The recompete window shows three awards with ultimate completion within the next twenty-four months and combined potential value of $1.2 million. Activity has grown from one award in 2021 to four in 2025, with work performed primarily in Banning, California and distributed across Northern and Central California monitoring station sites. NAICS concentration runs to site preparation contractors (7 awards) and electrical contractors (3 awards), aligned with PSC codes for construction of non-building facilities (8 awards) and housekeeping/fire protection (3 awards).
