The June 20 issue of ENR MidAtlantic will feature the annual ranking of Top Design Firms. Preliminary analysis shows continued revenue strength among architects and engineers in the MidAtlantic region, which includes Delaware, Maryland, Pennsylvania, Virginia, Washington D.C. and West Virginia. The 83 participating firms reported a total of $4.04 billion of work performed and billed in the area during 2015. That’s 5% above last year’s total of $3.85 billion.

Some individual firms saw even more dramatic increases in revenue, which we will delve into more in the June issue. 

Thank you to the firms listed below (in alphabetical order) that participated in this year’s survey. In the June edition, you will find breakout charts which will rank each firm based on specialty—such as civil engineer or architect—as well as market sectors, including health care, commercial, power and transportation.

Also, one firm will be selected as ENR MidAtlantic's Design Firm of the Year, based on revenue, innovation, sustainability, community service and other factors.

Please note that we may not have space in the print magazine to rank all 83 firms, but as always we will feature the full rankings on our website shortly after publication.
