NAICS 541320 – Landscape Architectural Services encompasses the planning, design, and management of outdoor environments through the integration of ecological, aesthetic, and functional principles. This includes site analysis, grading and drainage design, hardscape and softscape planning, sustainable stormwater management systems, native vegetation selection, and compliance with environmental regulations such as NEPA and wetland mitigation requirements. In government contracting, these services support infrastructure resilience, veteran wellness initiatives, and military base modernization, often as part of larger civil works, facilities, or environmental restoration projects. Landscape architects in this space collaborate closely with engineers, ecologists, and construction managers to deliver compliant, long-term solutions that enhance both usability and environmental stewardship. Top contractors in this sector include AECOM Technical Services, Inc. and DAP Construction Management LLC, both of which operate as large prime contractors with extensive experience in federal environmental and infrastructure programs. These firms typically lead multidisciplinary teams and manage complex, multi-year projects requiring specialized certifications in sustainable design and federal procurement compliance. The Department of Defense and the Department of Veterans Affairs are the primary federal buyers, driving demand through base landscape improvements, memorial site development, rehabilitation of VA medical center grounds, and ecological restoration on military lands. Their initiatives often prioritize accessibility, low-maintenance native plantings, and climate-resilient design to support long-term operational sustainability. The competitive landscape is concentrated among large firms with proven track records in federal environmental compliance and integrated project delivery. Opportunities exist for firms with expertise in sustainable site design, stormwater infrastructure, and adaptive reuse of military landscapes. Demand is increasingly tied to climate adaptation goals and veteran-centered therapeutic environments, creating niche opportunities for specialized design consultants and small businesses with niche certifications in ecological restoration.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 541320 work as a small business.

$9.0M
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.
