June 15 is the deadline for completing ENR Midwest's Top Specialty Contractors Survey, the basis for its annual ranking of the largest subcontracting firms in the region, including those located or operating in Illinois, Indiana, Michigan, Missouri, Ohio and Wisconsin.

The survey ranks firms in accordance with revenues accrued in the previous calendar or fiscal year, in this case 2014. The resulting list will be published in the Sept. 28 edition of ENR Midwest.

In addition to highlighting the performance of individual firms, the listing provides a collective snapshot of regional activity and serves as the basis for selecting ENR Midwest's Specialty Contractor of the Year. Firms are selected on the basis of their financial performance, as well as their execution of key projects in the region, with past honorees including Faith Technologies, ERMCO Inc., Baker Concrete Construction Co. and The Hill Group.
