Construction & Engineering Federal Contracting Overview
Federal construction contracts cover everything from military base construction and VA hospital renovations to road and bridge projects. The Army Corps of Engineers, GSA, and VA are the largest buyers of construction services. The primary NAICS codes for this sector are 236220, 237310, 237110, which contracting officers use to classify solicitations and identify qualified vendors. Top buying agencies include DOD, GSA, VA.
Small businesses pursuing construction & engineering contracts should evaluate their eligibility under the SBA size standards for their primary NAICS code. Qualifying businesses can compete for set-aside contracts reserved under programs such as SBA, 8A, SDVOSBC, WOSB, which significantly reduce the competitive field. Many construction & engineering contracts are multi-year or IDIQ vehicles, providing a stable revenue base for winning firms.
Federal procurement in this sector spans multiple contract types including firm-fixed-price, time-and-materials, and cost-plus arrangements. Understanding which contract type each agency prefers for construction & engineering work is critical for competitive pricing. Past performance in similar federal or commercial projects is typically a major evaluation factor.

Size Standards & Eligibility
Each NAICS code has an SBA-defined size standard that determines whether your business qualifies as "small" for set-aside contracts. For construction & engineeringcodes, size standards are typically measured by annual average revenue or employee count over the past 3–5 years. Meeting the size standard for your primary NAICS code opens access to set-aside programs that reserve a significant share of federal contracting dollars for small businesses.
