GRL Engineers offer a wide range of deep foundation testing and consulting services, nationwide. Most GRL Engineers have achieved Advanced Level or higher on both the PDCA/PDI Dynamic Measurement and Analysis Proficiency Test.
I-4 UltimateGRL 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
Seattle Center ArenaGRL 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
I-480 Valley View Bridge Deck ReplacementsThe widening of the I-480 Valley View Bridge was a design-build project for the Ohio Department of Transportation (ODOT). GRL Engineers provided Pile Driving Monitoring, Long-term Restrikes with the APPLE IV system, Static Load Tests and CAPWAP Analyses to assess resistance distributions. Read more
