Messer Construction Co. was recently ranked by Engineering News-Record (ENR) as the 68th-largest general contractor in the United States, based on 2013 revenue. The company’s $831.7 million revenue mark, the largest in its 81-year history, was up from $792.4 million the previous year, when it ranked 70th.

The ranking is part of ENR’s annual Top 400 Contractors list, which this year was published for the 50th-straight year. Messer is one of only 50 companies to have ranked in the top 400 in both 1964 and 2014. Furthermore, it is one of just 19 companies to have ranked in the top 100 on both lists.

In 1964, ENR ranked family-owned Frank Messer & Sons, Inc. No. 84 on its list, with $30.8 million in new contracts. In 1990, the company’s employees purchased the Cincinnati contractor and changed its name to Messer Construction Co. Soon, the company would begin to expand its footprint by opening regional offices throughout the Midwest and South.

Today, Messer has regional offices in nine cities and employs over 900 people. The company has appeared in the top 100 of ENR’s list in each of the last 12 years, and is considered among the country’s premier higher-education and health-care builders.
