2016 GIANTS 300 REPORT: Ranking the nation's largest architecture, engineering, and construction firms

For 40 years, the editors of Building Design+Construction have ranked the nation's largest AEC firms as part of the Giants 300 report. Below, we present the findings of our 2016 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, 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:
