Featured Projects
Northwest Railroad Bridge Project
In this case study, the northwest railroad project utilized GRLWEAP Wave Equation Analysis and Dynamic Load Testing on 3 indicator piles. Previous experience near the site indicated the potential for significant pile capacity increase with time. Restrikes were performed in an unusual way to optimize the foundation. Read More
Replacement Bridge Over Buffington Road and NFS Railroad
The SCDOT retained GRL Engineers to perform testing on a production shaft. Drilled shaft verticality and cleanliness were evaluated on the production shaft. Bi-Directional Static Load Testing was performed on the drilled shaft to determine the mobilized shaft resistance. Thermal Integrity Profiling to assess concrete integrity and shaft profile.
