PSC Z1AA: Maintenance of Office Buildings — Active Federal SAM.gov Contracts & NAICS Crosswalk

Federal procurement intelligence, spending breakdown, NAICS/NIGP crosswalk, and contract capture guide for PSC Z1AA (Maintenance of Office Buildings).

Product and Service Code (PSC) Z1AA — Maintenance of Office Buildings — is an official federal procurement classification within Portfolio Z — Maintenance, Repair, and Alteration of Real Property 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 $2.9 Billion annually under PSC Z1AA, with 420+ 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 Z1AA specifies the exact real property maint (z1) deliverable being purchased on the contract line item (CLIN). In federal solicitation architecture, PSC Z1AA is most frequently paired with Primary NAICS 236220 (Commercial and Institutional Building Construction), which carries an SBA small business size standard of $45.0 Million. Major buying commands—led by General Services Administration (PBS) (42% of spend), Department of Defense (38%), and Department of Veterans Affairs (12%)—use PSC Z1AA to categorize statements of work encompassing Preventive & Predictive Building Envelope, HVAC, Electrical & Plumbing Maintenance; Federal Building Chiller/Boiler Plant Operations, BAS Controls & Filter Replacements; and Roofing Maintenance, Waterproofing, Elevator Servicing & Fire Life-Safety Testing. Understanding how contracting officers cross-walk PSC Z1AA with NAICS 236220 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 Z1AA utilize a mix of open-market SAM.gov solicitations and pre-competed contract vehicles such as GSA PBS / DoD BOS. Depending on the acquisition threshold and market research results from Sources Sought notices, contracting officers frequently restrict PSC Z1AA 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 Z1AA 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 Z1AA maps directly to NIGP Commodity/Service Code 910-00 (Building Maintenance, Installation, and Repair Services) 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 Z1AA alongside matching state and local NIGP 910-00 bids, enabling capture teams to uncover hidden opportunities and generate compliant proposals faster.
