ENR Midwest has extended its Top Contractors Survey deadline to April 21, providing firms in Illinois, Indiana, Michigan, Missouri, Ohio and Wisconsin an additional two weeks to submit forms for Midwest's annual ranking of the region's largest builders.

Firms are ranked in accordance with their revenues for 2013.The listing will be published in the June 14 edition of ENR Midwest.

In addition to highlighting the performance of individual firms, the ranking provides a collective snapshot of construction activity in the Midwest. It also serves as a short list for selecting ENR Midwest's 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 previous honorees including BMW Constructors, Miron Construction Co. and Clayco Corp.
