Transportation Projects
NC Department of Transportation; Various Locations
The F&R Raleigh office has been providing services to the North Carolina Department of Transportation (NCDOT) since NCDOT first began utilizing outside geotechnical firms in 1984. Since that time, F&R has performed many subsurface investigations for bridges and roadways throughout the state. All work is performed to strict NCDOT Geotechnical Unit guidelines. F&R works both directly for the Geotechnical Unit under a limited services contract on an as needed basis and as a partner with design firms on a project-by-project basis.
I-77 Design/Build Project; Charlotte, NC
F&R’s Charlotte and Raleigh offices were a part of a design-build team on the first design-build project awarded by NCDOT. The project involved widening I-77 in Charlotte from the I-85 interchange northward to the Charlotte Outer Loop, a distance of approximately 8 miles. F&R provided geotechnical engineering and construction materials testing services during the design and construction phases of the project. Foundation designs were required at five bridge sites originally, with two additional bridges for a high occupancy vehicle (HOV) lane later added by NCDOT. Additional borings were required at two of the bridge sites and at the new bridge locations along the HOV lane. Furthermore, F&R provided foundation designs and soil borings for noise walls proposed along the route. Temporary pavement designs were performed to carry traffic during the various construction phases. Subgrades were also analyzed and tested with either lime or cement to determine the appropriate mix design to stabilize the subgrades to conform to NCDOT requirements. After mixing in the field, the subgrade was again sampled and testing was performed by F&R to confirm that the required strength had been achieved. .
SC Department of Transportation; Various Locations
F&R Greenville has provided geotechnical engineering and construction materials testing services to the South Carolina Department of Transportation (SCDOT). F&R has had the opportunity to provide geotechnical drilling services for numerous bridge overpass and segmented wall project locations throughout the state. F&R has also provided laboratory materials testing for the SCDOT District Laboratories during work overflow periods. F&R’s maintains AASHTO certification of its Greenville laboratory to allow for necessary compliance testing. All work is performed to strict SCDOT and AASHTO guidelines.
Light Rail System; Charlotte Area Transit System; Charlotte, NC
The Charlotte Area Transit System (CATS) and the Metropolitan Transit Commission (MTC) has selected light rail transit along an existing railroad right-of-way as the preferred alternative for rapid transit service in Charlotte’s South Corridor. This represents the first light rail project in North Carolina, and it has already generated over $250 million in private sector development. The proposed light rail project is approximately 11 miles long, running south from uptown Charlotte to the suburban town of Pineville, NC. Fifteen potential station locations along the light rail alignment are proposed. Based on ridership estimates of 15,000 linked trips per day, initial revenue operations will require between 10 and 12 light rail vehicles. Capital costs are estimated to be $331 million. The system will operate on separate tracks, generally within the Norfolk Southern right-of-way.
Route 288; Powhatan and Goochland Counties, VA
Under the Public-Private Transportation Act of 1995 (PPTA), the Virginia Department of Transportation awarded a $236 million contract to APAC-Virginia, Inc. of Danville for the completion of Route 288 around Richmond, Virginia. APAC formed a partnership with Koch Performance Roads, Inc. and CH2MHILL to assist with the project. F&R has been contracted by CH2MHILL to provide construction materials testing during the construction phases of this project. The team will build new segments of Route 288 in Powhatan and Goochland counties and complete four lanes of Route 288 from the Powhite Parkway (Route 76) in Chesterfield County to Interstate 64 in Goochland County, completing a planned western loop around Richmond. The project totals 17.5 miles and is planned for completion by late 2003.
