Below are some examples of our recent work. Projects include both completed and ongoing work.
Emergency Bridge Package 2018-2A DB
Marlboro and Dillon Counties, South Carolina
2019 ACEC-SC Engineering Excellence Award Winner
Carolina TEA is the Lead Engineer performing project management, bridge design, and construction engineering services for the emergency replacement of three bridges. Palmetto Infrastructure, Inc., with Carolina TEA, won the contract in a competitively bid design-build process. The replacement bridges consist of single-span structures at S-51 (70 ft bridge) and S-400 (50 ft bridge), and a 3-span structure at S-33 (100 ft bridge). Engineering services include project management, roadway design, bridge design, hydraulic modelling, roadway hydraulics, geotechnical exploration and design, hazmat studies, permitting, utility location and coordination, SUE, ROW acquisition, surveying, and development of as-builts.
US 278 Corridor Study
Beaufort County, South Carolina
Carolina TEA, as a subconsultant to KCI, is leading the Structures for the seismic study, retrofit, and/or replacement of the US 278 bridges over Mackay Creek and Skull Creek (the Intracoastal Waterway). Alternatives are being developed as part of this study to determine a preferred roadway alignment for the new 6-lane entryway into Hilton Head. Public interest in the project is very high, with many at Hilton Head and Beaufort County desiring a new “Gateway” onto the island.
S-77 over Lemon Swamp &
S-385 over Smith Branch
Bamberg County, South Carolina
Carolina TEA was selected to provide design services for the replacement of two bridges in Bamberg County. The roadways will be closed with traffic detoured during construction. The Project includes bridge, roadway and hydraulic design, survey, utility coordination, public involvement, NEPA documentation, geotechnical investigations and design, ROW acquisition, and construction services. Carolina TEA anticipates single-span cored slab bridges at each location. Approach roadways will be minimized to reduce impact to the surrounding streams, wetlands, and residences.
Bridge Load Ratings
SCDOT Districts 2, 4, and 7
Carolina TEA is performing bridge inspection, load rating, and quality control reviews for the KCI (District 4) and WSP (Districts 2 and 7) teams. Carolina TEA is performing the inspection and rating of 86 bridges and culverts in District 4 for the KCI team. Several culverts have been identified that will be load tested to avoid load posting these structures. The culverts show minimal signs of distress, but do not rate based on the given parameters. We are performing the quality control reviews for 2,557 bridge and culvert sites in Districts 2 and 7 for the WSP team.
