Every spring, the editors of Building Design+Construction survey the nation's largest architecture, engineering, and construction firms to identify the most prominent design and construction firms across 25 building sectors and specialty categories.
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).
