Welcome to the 44th edition of Building Design+Construction's Giants 400 Report (formerly Giants 300). The editors felt a name change was necessary given the growing number of firms (more than 480 this year) that participate in the annual ranking of the nation's largest architecture, engineering, and construction firms.
The 2020 Giants 400 Report is our most expansive package yet, with more than 130 rankings across 25 building sectors and specialty categories.
The complete findings for the individual categories are presented below. Download a PDF of all 2020 Giants 400 Rankings (short registration required)
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).
If your firm would like to participate in the next Giants 400 survey, download the 2022 Giants 400 survey. Surveys are due April 22, 2022.
