Construction Engineering and Inspection services (CEI) are required for contract administration, materials sampling, and testing for various construction projects. Long Engineering’s (LONG) CEI technicians specialize in monitoring the contractor’s on-site construction activities, as well as inspecting materials entering into the work in accordance with plans, specifications, and special provisions to ensure that the overall construction contract meets strict guidelines. 

LONG provides CEI services throughout the Southeast on city, county, and state transportation projects to ensure compliance with project specifications. Many of our inspectors have their Roadway Testing Technician (RTT), Asphalt Inspection, and/or Concrete Inspection certifications. In addition, they also possess the Georgia Department of Transportation (GDOT) Worksite Erosion Control Supervisor certification, and are equipped with materials testing equipment, as well as nuclear density gauges to inspect asphalt, base, and earth compaction.
