PSC Y1AA

Overview

The Product Service Code (PSC) system standardizes how the U.S. federal government classifies purchased products and services for procurement, reporting, and spend-analysis purposes; PSCs are used in FPDS and related acquisition systems and are maintained through the PSC Manual on Acquisition.gov. The PSC Manual provides the official list of PSC entries and descriptive labels used by agencies for reporting and spend analysis. ¹

PSC Y1AA — Construction of Office Buildings — is the PSC label used to identify procurements for the construction of office-building facilities. The PSC Manual lists Y1AA within Category Y (Construction of Structures/Facilities) as the official descriptive code; the manual provides the code name but does not define detailed technical line-item scope beyond the label. ¹

The PSC Manual provides the official code list but does not prescribe contract delivery methods or procurement strategy. ¹
