About the company
Andrew C Chen, doing business as Tectonics, is a minority-owned small disadvantaged business sole proprietorship based in Emeryville, California, delivering architectural, engineering, design, and construction services to federal defense and civilian agencies as a prime contractor on 81% of recent awards. The vendor holds primary SBA designations as a self-certified small disadvantaged business and Asian-Pacific American-owned enterprise, with DOT certified DBE status.
Tectonics operates predominantly in federal facilities modernization and infrastructure support. The vendor's capability footprint centers on multi-discipline architectural and engineering services including site planning, schematic design, construction documents, cost estimating, specification writing, and contract administration for building renovations, HVAC upgrades, fire protection systems, electrical and utility infrastructure improvements, and facility assessments. Recent prime work includes a $2.56 million delivery order from Naval Facilities Engineering Command for Bachelor Enlisted Quarters repairs at Marine Corps Base San Diego (awarded September 2025, ultimate completion September 2026), a $1.65 million delivery order from the Marine Corps for BEQ repair planning at Camp Pendleton (July 2025), and a $1.35 million modification from the Marine Air Ground Combat Center for tank inspection and seismic study services at Twentynine Palms (September 2024).
Customer concentration reflects strong defense-agency alignment. Naval Facilities Engineering Command anchors the vendor's dollar footprint at $116.5 million across 33 awards, while the General Services Administration Public Buildings Service Region 9 carries 77 awards valued at $38.7 million. The Department of the Army Corps of Engineers Engineering Support Center Huntsville represents $16.7 million across four awards, and the Department of Agriculture contributes $14 million across two awards. By award count, GSA Region 9 leads with 77 awards, followed by the Department of the Navy (67 awards) and the Department of Agriculture Agricultural Research Service (60 awards), with these three agencies covering 58% of all awards.
Tectonics holds a $99 million single-award Indefinite Delivery/Indefinite Quantity contract with Naval Facilities Engineering Command Southwest, set aside 100% for total small business, awarded January 2022 with ultimate completion January 2030. This vehicle has generated 35 delivery orders ranging from approximately $144,000 to $2.56 million, collectively exceeding $30 million. The vendor also executes task orders under the SDVOSB HUBZone Multiple Award Construction Contract Northwest (65 task orders), General Services Administration Schedule GS09P15KTD0008 (57 task orders, $13.6 million combined value), and other federal construction and engineering IDIQs including N6247322D1402 (34 task orders, $30 million combined value) and 533K1569066 (31 task orders).
Activity has declined materially from recent peaks. The vendor recorded 64 awards in 2023, dropping to 22 in 2024, six in 2025, and four through April 2026. Combined potential value across all 542 prime and sub awards stands at $205.4 million, with $98.9 million obligated (48% of potential). Ten awards face ultimate completion within the next twenty-four months, carrying combined potential value of $11.6 million and presenting recompete exposure.
Tectonics operates predominantly as a prime contractor but subcontracts substantially to larger construction and engineering primes. The vendor reports sub-awards across the federal footprint, with I.e.-Pacific, Inc. as the most frequent prime partner on naval base renovation, modernization, and design-build projects at Naval Amphibious Base Coronado, Naval Station Everett, Naval Submarine Base Bangor, and Puget Sound Naval Shipyard. On SCI-reportable federal service contracts (a subset above $150,000), the vendor invoiced $1.7 million across FY2022–FY2024, declining from $1.1 million in FY2022 to $209 thousand in FY2024, with median government-paid rates around $178.94/hr on prime records and a 90th percentile reaching $1,553.25/hr. The SCI dataset shows roughly 0.6 FTEs delivered in FY2024 across prime and sub work, down from 1.5 FTEs in FY2022.
