GEC FDOT roadway projects


Since 1991, GEC has provided geotechnical engineering services for some of Central Florida's landmark transportation infrastructure projects. With offices in Orlando and Kissimmee, GEC serves all of Central Florida's transportation agencies including the Florida Department of Transportation (FDOT), Florida's Turnpike Enterprise, and the Orlando-Orange County Expressway Authority (OOCEA).

GEC is recognized for its innovative technical approaches to complex issues of constructability, meeting tight design and construction schedules, and helping the project team reduce risks and the cost of construction.

GEC core services include geotechnical engineering for highway and bridge design, environmental contamination screening, and construction phase services, including pile driving inspection and materials testing and inspection.

The GEC technical staff is thoroughly familiar with FDOT requirements, procedures and expectations for consultant performance. GEC's depth of experience and large technical staff ensure streamlined proposal preparation, field investigation, laboratory testing and reporting.
