Established in 2004, Quality Control Services (QCS) is an Ohio DBE, EDGE and SBE certified Engineering firm headquartered in Cleveland, Ohio. While founded primarily to provide industrial coating inspection, QCS has grown to be one of the elite transportation construction inspection firms in the area now providing Engineering, Construction Administration, Construction Management and Construction Support Services.

For over a decade, QCS has successfully staffed construction inspection contracts as a prime and/or subconsultant for ODOT in Districts 3, 4, 6, 7, 8, 10, and 12. QCS also provided IQF inspection services for Parts 1 & 2 of the historic Cleveland Innerbelt Projects and the multi-year I-71/I-670 Columbus Crossroads Project. We are also responsible for inspection and testing services on two of the three Ohio Bridge Partnership contracts. Most recently, we provided Project Management and Inspection Services on both the Snell and Eisenhower Locks under the direction of the the Saint Lawrence Seaway Development Corp.

QCS understands that in this industry success is measured one contract at a time, and positive reputations are built through consistency. From job staffing and employee communication to project documentation and invoicing, every aspect of contract delivery is monitored to ensure that clients receive only the highest quality service.
