According to ENR, the top 500 design firms in the United States ranked by revenue generated revenue of approximately $59.8 billion in 2005, which was an 11.8% increase over 2004. Of this $60 billion in revenue, the largest two categories were general building and transportation, representing $23 billion and $20 billion, respectively. Water and wastewater combined represented an additional $13 billion in 2005 revenues.

The U.S. Department of Commerce forecasts that increases in work associated with the nonresidential building, power and highway markets will contribute to the overall value of new construction contracts awarded in the United States, which are expected to increase slightly to $1.17 trillion in 2007. The U.S. Department of Commerce projects that this growth in nonresidential construction will counter expected major declines in the value of residential construction during 2007.

Transportation services include the design and construction management of a broad range of transportation infrastructure projects, including airports, seaports, bridges, tunnels, railway lines and highways. According to ENR, the top 500 engineering design firms earned $20.3 billion in revenue in 2005 as a result of transportation work.

ENR reports that $22.9 billion in revenue was earned by the top-500 design firms in 2005 from general building. The U.S. Department of Commerce projected in late 2006 that commercial construction spending would increase 11% in 2006 and rise another 10% during 2007 to reach $90 billion, that education construction spending would rise 7% in 2006 and rise another 5% in 2007 to reach $88.3 billion, that office construction would rise 15.1% in 2006 and rise another 11.8% in 2007 to reach $61.4 billion and that lodging construction would rise 50% in 2006 and increase an additional 14.7% in 2007 to approach $22.6 billion.

There is significant global demand for water, wastewater and environmental services. ENR reports that the water and wastewater market contributed $13.4 billion in 2005 revenue to the top-500 design firms. FMI Corp., a Denver-based industry management consultant, predicts that water supply construction spending will increase 9% and that sewer system spending will rise 10% in 2007.
