PSC C1AA: Architect and Engineering - Construction: Office Buildings — Active Federal SAM.gov Contracts & NAICS Crosswalk

Federal procurement intelligence, spending breakdown, NAICS/NIGP crosswalk, and contract capture guide for PSC C1AA (Architect and Engineering - Construction: Office Buildings).

Product and Service Code (PSC) C1AA — Architect and Engineering - Construction: Office Buildings — is an official federal procurement classification within Portfolio C — Architect and Engineering Services managed by the General Services Administration (GSA) under the Federal Procurement Data System (FPDS) Product and Service Codes Manual. Across federal agencies, contracting officers obligate approximately $1.7 Billion annually under PSC C1AA, with 190+ Bids active solicitations, pre-solicitation notices, and task order RFQs circulating on SAM.gov and agency e-Buy portals. While a 6-digit NAICS code defines a contractor's overall industry and Small Business Administration (SBA) size standard, PSC C1AA specifies the exact architect & engineering deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC C1AA is most frequently paired with Primary NAICS 541310 (Architectural Services), which carries an SBA small business size standard of $12.5 Million ($25.5M Eng). Major buying commands—led by General Services Administration (PBS) (38% of spend), U.S. Army Corps of Engineers (USACE) (36%), and NAVFAC (18%)—use PSC C1AA to categorize statements of work encompassing Brooks Act (FAR Subpart 36.6) SF-330 Qualifications-Based Architectural Design; 35%/65%/95%/100% Design Submissions, BIM (Revit) Modeling & Cost Estimating; and Design-Build Request for Proposal (RFP) Bridging Documents & Charrettes. Understanding how contracting officers cross-walk PSC C1AA with NAICS 541310 is critical because many agencies filter dynamic small business searches, GSA e-Buy distributions, and historical FPDS incumbent spend analyses by PSC rather than NAICS alone. Procurement teams issuing awards under PSC C1AA utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as Brooks Act SF-330. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC C1AA competitions to certified small businesses—including 8(a) Business Development participants, Service-Disabled Veteran-Owned Small Businesses (SDVOSB), Women-Owned Small Businesses (WOSB), and HUBZone firms. Offerors responding to PSC C1AA RFPs must demonstrate strict compliance with applicable FAR and DFARS clauses, deliverable quality standards, and supply-chain or labor regulations. For contractors expanding across both federal and state/local (SLED) markets, PSC C1AA maps directly to NIGP Commodity/Service Code 906-07 (Architect Services, Professional Building Design (Schools, Civic, Healthcare)) used by state procurement portals, municipal purchasing departments, public universities, and K-12 school districts. InTandem's automated government contracting platform continuously monitors live SAM.gov notices tagged with PSC C1AA alongside matching state and local NIGP 906-07 bids, enabling capture teams to uncover hidden opportunities and generate compliant proposals faster.
