NAICS 238190 – Other Foundation, Structure, and Building Exterior Contractors encompasses specialized construction services that support the foundational, structural, and exterior envelope systems of buildings and infrastructure. This includes work such as concrete footing and slab installation, masonry veneer and stone cladding, waterproofing, roofing systems, flashing, gutters, downspouts, and other exterior finishes critical to structural integrity and weather resistance. These contractors often operate as subcontractors to general builders or as specialized primes on federal projects requiring precision in building envelope performance, seismic retrofitting, or historic preservation. The work is essential to lifecycle maintenance, new construction, and resilience upgrades across federal facilities, particularly in mission-critical environments where durability and code compliance are non-negotiable. Top contractors in this sector include AAECON GENERAL CONTRACTING LLC, ASPEN CONSTRUCTION COMPANY, GOINS CONSTRUCTION LLC, HUGUS INC., DAP CONSTRUCTION MANAGEMENT LLC, HERITAGE CONSTRUCTION LLC, PHOENIX GENERAL CONTRACTORS, LLC, PVPII - FNSS ACQUISITION, INC, and RYMAR CONSTRUCTION, INC. These firms range from small businesses with niche expertise in masonry and waterproofing to mid-sized primes with capabilities in full exterior system integration. The competitive landscape is characterized by regional dominance, specialized certifications, and deep familiarity with federal building codes and sustainability standards. The Department of Defense, Department of the Interior, Department of Homeland Security, and Environmental Protection Agency are the primary federal buyers, driving demand through facility modernization, base infrastructure upgrades, and mission-critical site enhancements. Projects often involve historic building rehabilitation, military housing renovations, and environmental compliance at remote or sensitive locations. The market is highly fragmented but opportunity-dense, with consistent demand for contractors who can deliver code-compliant, high-performance exterior systems under strict federal procurement rules. Contractors with expertise in energy-efficient envelopes, moisture management, and ADA-compliant exterior finishes are best positioned to compete. Long-term maintenance contracts and task orders under GWACs and IDIQs represent recurring revenue streams.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 238190 work as a small business.

$19.0M
Applies to the whole industry code

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.
