Now in its 42nd year, Building Design+Construction's annual Giants 300 report ranks AEC firms by discipline and across more than 20 building sectors and specialty services. More than 480 U.S.-based architecture, engineering, and construction firms participated in the 2018 Giants 300 report.
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, etc.) data labeled “Construction” includes all delivery methods combined (GC, DB, CM at risk, IPD, CM agent, PM).
