Featured Projects
I-4 Ultimate
GRL Engineers has been an integral force behind the I-4 Ultimate project with over 150 bridge foundations tested. GRL Engineers were instrumental in providing PDA Dynamic Testing services with associated CAPWAP Analyses to the Florida Department of Transportation (FDOT). Read More
Harris County Toll Road Authority SH 249
The Harris County Toll Road Authority brought GRL Engineers on to perform quality control testing on excavated test shafts. Drilled shaft verticality was assessed using the Shaft Area Profile Evaluator (SHAPE) device and Crosshole Sonic Logging was performed to evaluate concrete quality around the shaft cage. Read More
Seattle Center Arena
GRL Engineers performed Thermal Integrity Profiling on the Seattle Center Area, the world's first net zero certified arena. GRL tested and analyzed the collected thermal data for 21 drilled shafts. The tested shafts were either 36 or 78 inches in diameter with shaft lengths from 80 to 93 feet. Read More
