Location: Lee County, FL
Client: Florida Department of Transportation (FDOT)

Volkert (formerly Allied) performed the contractor quality control (CQC) for the Joint Venture on 1.6 miles of I-75 from North of SR 80 to South of SR 78 in Lee County, Florida.

This Design/Build/Finance project will widen I-75 from a four-lane section to an eight-lane section with six through lanes plus an auxiliary lane in each direction. The capacity improvements will be accomplished by adding two12-ft lanes and a 12-ft shoulder to both north and south bound I-75. The major item of work will be the widening of 4 bridge pairs, or a total of 8 bridges, including the Category Two Caloosahatchee Bridge, a major water crossing. Sound Barrier Walls will be constructed along the Morse Shores and Dos Rios communities located along the SR 80 I-75 Southbound exit, and northbound entrance ramps.

The project includes approach roadway improvements, milling and resurfacing of the mainlines and applicable ramps, median crossover closure, signing and pavement markings, construction of stormwater management facilities, SR 78 drainage improvements, structural accommodation for ITS conduits, and a median barrier system. Volkert (formerly Allied) provided a full time QC Tech for concrete and earthwork inspection and lab testing as well as installing settlement plats and monitoring of such for retention ponds.
