2024 Giants 400 Report: Ranking the nation's largest architecture, engineering, and construction firms
By BD+C Staff
A record-high 602 architecture, engineering, and construction firms participated in Building Design+Construction’s 2024 Giants 400 Report. The final report includes 137 rankings across 25 building sectors and specialty categories. The individual rankings will be posted periodically throughout November and December 2024 and January and February 2025.
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.
Firms were asked to report revenue from commercial, institutional, multifamily, and industrial “buildings” work completed by their U.S./Canada-based staff/studios/divisions/teams. They were asked to exclude revenue from non-buildings work or from single-family residential work.
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).
All building sector categories except for 08 and 23 include multiple rankings for the sector: Top Architecture+AE Firms; Top Engineering+EA Firms; and Top Contractors+CM Firms.
