This is Our Story...

CTL Engineering is a full service consulting engineering, testing, inspection, and analytical services company. Formerly known as Columbus Testing Laboratory, the company was established in 1927 as a privately held independent engineering and testing laboratory serving the local community. During its early years, the company focused mainly on soils, foundation engineering, and construction testing and inspection services. The successes, experience, equipment, and expertise gained in these areas led to a natural expansion into the metallurgical, non-destructive testing, mechanical, mining, roofing, and environmental service industries.

Initially, CTL Engineering’s client base was mostly limited to Columbus, Ohio and its surrounding communities, but has grown significantly since. Today, CTL Engineering regularly performs services not only throughout Ohio, but also in all of the Mid-Atlantic and Midwestern states. In addition to our corporate headquarters in Columbus, Ohio, we have expanded our service centers to include eight other regional offices. CTL Engineering became an Employee Stock Ownership Plan (ESOP) Company in 1991. It has recently been awarded Encouraging Diversity Growth & Equity (EDGE) status by the Ohio Department of Administrative Services, as well as Minority Business Enterprise (MBE) status by both the South Central and Northern Ohio Minority Business Council, affiliates of National Minority Supplier Development Council (MNSDC).
