PSC Y1DB

Overview

The Product Service Code (PSC) system is a government-wide taxonomy used to classify goods and services procured by the U.S. federal government. PSCs are recorded in procurement reporting systems (for example FPDS) and maintained through the PSC Manual to support consistent tracking, analysis, and reporting of federal spending. The PSC Manual supplies code descriptors and group listings that contracting activities use to select valid PSC values for reporting and data analysis.¹

PSC Y1DB is the PSC entry described as "Construction of Laboratories and Clinics." Contracting activities apply Y1DB when the primary purpose of a construction contract or task order is to build, renovate, or deliver facilities intended for laboratory or clinical use, including supporting systems, utilities, and commissioning as reflected in the PSC descriptor.¹

What this PSC covers

• Laboratory facility construction and new-build laboratory buildings
• Clinical facility construction and clinic buildings
• Controlled environments, cleanrooms, and specialized research suites
• Mechanical, plumbing, and HVAC systems sized/designed for laboratory/clinical use
• Site preparation and utilities specific to laboratory or clinical operations
• Commissioning, testing, and turnover of laboratory/clinic systems

Contracting context

Federal contracting systems require selection of the PSC that best identifies the primary product or service being procured; PSC entries such as Y1DB are used in FPDS reporting and other acquisition records to classify construction of laboratory and clinic facilities. Reporting guidance and FPDS data-element expectations for PSC and NAICS usage are provided in FPDS documentation and system guidance.²

Frequently asked questions

• Q: What does PSC Y1DB specifically denote?

  • A: PSC Y1DB denotes construction-related procurements whose primary objective is the construction of laboratories and clinics. The PSC Manual lists the descriptor "Construction of Laboratories and Clinics" as the official code label, and contracting officers should use that descriptor to guide reporting and classification.¹

• Q: Where is Y1DB reported or visible in federal systems?

  • A: Y1DB is reported in federal procurement reporting systems such as FPDS. Agencies record the applicable PSC on contract actions to identify the primary product or service; FPDS requires a valid PSC from the PSC Manual for contract reporting and analysis.²

• Q: Which NAICS should be used with Y1DB?

  • A: The PSC Manual does not prescribe a single NAICS mapping for Y1DB; NAICS selection depends on the contract’s principal work (for example, commercial/institutional building construction NAICS are frequently used). Not specified by official sources ¹

• Q: When should a contracting officer choose Y1DB versus Y1DA?

  • A: Choose Y1DB when the primary work is laboratory or clinic construction; choose Y1DA when the primary work is hospital or infirmary construction. The PSC Manual groups these codes under construction-of-structures classifications and provides descriptors to distinguish them.¹

• Q: Are there reporting rules for PSC selection?

  • A: FPDS guidance directs use of the PSC that best identifies the product or service procured; if multiple codes apply, report the code representing the largest share of contract value and follow FPDS reporting instructions and glossary definitions for PSC usage.³
