What the government is buying

The Defense Logistics Agency (DLA) is soliciting offers for an engine block assembly under a total small business set-aside. This procurement falls under Federal Supply Classification 28, which covers engines, turbines, and components. Engine block assemblies are foundational components in internal combustion engines, serving as the main housing for cylinders, crankshaft, and other critical engine parts.

NAICS code 333618 covers "Other Engine Equipment Manufacturing," a classification that includes manufacturers of gasoline engines, diesel engines, and component parts. DLA Land and Maritime, based in Columbus, Ohio, manages this procurement on behalf of weapons systems support. DLA Land is one of DLA's primary commodity commands, responsible for supporting land weapons systems and associated equipment for the military services.

Key facts

Who can bid

This opportunity is restricted to small businesses under NAICS 333618. To qualify, a business must meet the Small Business Administration's size standard for this NAICS code. Manufacturers should verify their size status in their SAM.gov profile and ensure their primary North American Industry Classification System code matches or aligns with 333618.

Eligible bidders should have experience in engine component manufacturing, quality systems certified to military or aerospace standards (typically AS9100 or ISO 9001), and the capacity to meet DLA's delivery and packaging requirements. Contractors must be registered in SAM.gov with active status and appropriate representations and certifications. Past performance with DLA or other defense agencies may strengthen a proposal but see the solicitation for specific requirements.

How to put together a competitive bid

Manufacturing and technical capability: Demonstrate your ability to produce engine block assemblies to military specifications. Include details on machining capabilities, material sourcing, and dimensional tolerances. Technical data packages for DLA engine parts typically require strict adherence to original equipment manufacturer drawings.

Quality assurance: Emphasize your quality management system, inspection protocols, and traceability procedures. DLA Land and Maritime frequently requires compliance with MIL-STD or military performance specifications for engine components.

Pricing strategy: Analyze historical pricing for similar DLA engine part procurements if available. Submit your best price upfront—these are typically firm fixed-price awards. Factor in material costs, tooling amortization, and DLA's unique packaging and marking requirements (often MIL-STD-129 or MIL-STD-2073).

Past performance: Prepare documentation of relevant manufacturing experience, particularly for defense or heavy-duty engine applications. Include delivery performance metrics and any existing government contracts.

SAM.gov completeness: Verify your entity registration, representations, and any required socioeconomic certifications are current and accurate before submitting.
