The PSC code K091 covers the modification of equipment specifically related to fuels, lubricants, oils, and waxes. This classification is used in federal contracting to identify services that involve altering or upgrading existing machinery and equipment that handle or utilize these substances. Such modifications can include adjustments to improve efficiency, safety, compatibility with new fuel types, or compliance with updated environmental regulations. Government agencies utilize this PSC to procure specialized technical services that ensure their operational equipment meets current standards and functional requirements related to fuel and lubricant management. Contractors providing these services often have expertise in mechanical, chemical, or industrial engineering fields focused on maintenance and enhancement of fuel-related systems.

Typical Buyers & Agencies for PSC K091

Typical buyers for PSC K091 include defense agencies such as the Department of Defense (DoD), the Department of Energy (DOE), and other federal organizations managing fleets, energy infrastructure, or industrial facilities. These agencies require modifications to ensure their equipment operates reliably with specific fuel types or lubricants, often under demanding or specialized conditions. Agencies involved in logistics, transportation, and facility management also utilize this PSC to maintain and upgrade their equipment fleet to meet mission-critical objectives. The PSC assists contracting officers in sourcing qualified contractors capable of performing these technical modifications efficiently and safely.

Common Contract Types for PSC K091

Contracts awarded under PSC K091 commonly include firm-fixed-price, cost-reimbursement, and time-and-materials types depending on the complexity and scope of the modification work. Procurement methods range from full and open competitions to negotiated contracts, especially when modifications require specialized expertise or proprietary technology. Task orders under indefinite-delivery/indefinite-quantity (IDIQ) contracts are also typical, allowing agencies flexibility to address ongoing equipment modification needs. Use cases often involve planned equipment upgrades, retrofitting for new fuel standards, or compliance-driven changes to existing machinery.
