2014 Giants 300 Report

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:

Rankings by Building Sector

In 1871, The Carondelet School, designed by Frederick William Raeder, opened to educate more than 400 children of laborers and manufacturers in St. Louis. The building is getting a second lease on life, as it has undergone a $2 million renovation by goBRANDgo!, a marketing firm for the manufacturing and industrial sectors.

Metal roofing trends

New ideas in design and constructability are radically changing how metal systems are used as roofing for commercial and institutional buildings. Behind the investment in these new kinds of expressions and construction approaches is a growing interest in improved performance and reduced environmental impact. Metal roofing systems can cut cooling and heating loads significantly, according to the EPA.
