PSC C1JZ

Overview

The U.S. government uses Product Service Codes (PSC) to consistently classify the products and services it buys, supporting federal reporting, analysis, and transparency in systems such as FPDS and SAM. PSCs are governed and updated through the PSC Manual issued on Acquisition.gov. ¹

PSC C1JZ is defined in the PSC Manual as “Architect and Engineering- Construction: Miscellaneous Buildings.” It identifies architect-engineer (A/E) services supporting construction for building types that do not fit other named C1 subcategories; specific examples are not enumerated in the manual. ²
