ENR Midwest once again is compiling a list of the largest design firms in the region. The annual listing ranks firms in accordance with their regional revenues for the previous calendar or fiscal year – in this case 2013. To qualify, firms must be located in Illinois, Indiana, Michigan, Missouri, Ohio or Wisconsin. Surveys must be completed by Feb. 24.

The listing will be published in the June 2 edition of ENR Midwest.

In addition to highlighting the performance of individual firms, the listing provides a snapshot of design activity in the region while serving as the basis for selecting ENR Midwest's Design Firm of the Year.

Honorees are selected on the basis of financial performance, innovations and execution of key projects in the region. Previous honorees include Burns & McDonnell, HDR Inc. and KJWW Engineering Consultants.
