NAICS 327331 – Concrete Block and Brick Manufacturing covers the production of standardized masonry units including concrete blocks, bricks, pavers, and related precast concrete elements used in structural and non-structural construction applications. These products are essential for defense infrastructure projects such as barracks, perimeter walls, guard posts, training facilities, and utility enclosures, where durability, fire resistance, and load-bearing capacity are critical. Manufacturing processes involve molding, curing, and finishing techniques to meet ASTM and military specification standards, often requiring compliance with seismic, thermal, and environmental performance criteria. This NAICS plays a foundational role in federal construction and civil works programs, supporting both new builds and facility upgrades across military and federal installations. ENFIELD ENTERPRISES LLC is the leading contractor in this sector, specializing in custom-engineered concrete masonry solutions tailored to defense and federal construction requirements. The competitive landscape is dominated by small businesses and regional manufacturers with established certifications, including HUBZone and SDVOSB status, who leverage local production capabilities to meet just-in-time delivery demands on remote or restricted sites. The Department of Defense is the primary federal buyer, driving demand through base modernization, force protection, and expeditionary construction initiatives. Projects often involve rapid deployment of durable infrastructure in austere environments, requiring compliance with UFC and MIL-STD specifications. Procurement is typically channeled through construction contracts managed by the Corps of Engineers and Defense Logistics Agency. The market is characterized by localized supply chains and high logistical barriers to entry, favoring contractors with on-site production, transportation logistics, and prequalification for federal construction programs. Opportunities exist for firms with expertise in sustainable concrete formulations, modular design, and rapid-cure technologies that reduce field installation time and support mission-critical timelines.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 327331 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
