The editors of Building Design+Construction magazine present the findings of our annual Giants 300 Report, which ranks the leading firms in the AEC industry for building-type revenue, green building work, BIM revenue, and more.

Data for our Giants 300 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, Multifamily, Government, etc.) data labeled “Construction” includes all delivery methods combined (GC, DB, CM at risk, IPD, CM agent, PM).

We'd like to thank our Giants 300 sponsors for their support of the recognition program:
