For the past 45 years, the editors of Building Design+Construction have surveyed the largest architecture, engineering, and construction firms in the U.S. to identify the Giants 400—the nation's most prominent AEC firms by revenue. This year, 499 firms participated in BD+C's Giants 400 report, making it the most extensive Giants report to date.

The complete findings for the individual categories are presented below. Note: The building sector categories and specialty rankings will be posted periodically throughout September. A PDF of all 2021 Giants 400 Rankings will be posted in late September.

Data for our Giants 400 charts is based on information supplied by the respective firms. Firms are asked to verify the accuracy of their data. The Construction section includes two types of statistics. The Contractors chart reflects revenues for general contracting, design-build, CM at risk, and IPD—projects where all revenues flow through the contractor.

The CM Agent + PM chart lists firms that derive their revenues through fees. In the subsequent market-specific sections (Healthcare, Data Centers, etc.) data labeled “Construction” includes all delivery methods combined (GC, DB, CM at risk, IPD, CM agent, PM).
