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.
Pensacola Bay BridgeThe U.S. 98 Pensacola Bay Bridge replacement project began in 2017 to address hurricane evacuation traffic needs. The replacement required PDA Testing on test piles and production piles. Data was assessed via CAPWAP® data analyses to provide simulated static load testing. Hurricane Sally interrupted construction in 2019, and potential damages to production piles were assessed using Low Strain Integrity Testing. Read more
Toombs County Bridge Replacement over the Altamaha RiverGRL performed Drilled Shaft Verticality Assessment, Shaft Base Cleanliness Assessment, as well as Bi-Directional Static Load Testing (“BDSLT”) services. A multi-level jack assembly configuration increased the complexity of shaft installation requirements, load test execution, and test data analyses. Thermal Integrity Profiling was also utilized during concrete curing to measure thermal data every 15 minutes. Read more
I-77 Canton Bridge StructuresThe large aquifer in Canton, OH presented multiple drilled shaft installation challenges on the I-77 mainline bridge structures. GRL Engineers were involved in mulitple phases of construction, providing a variety of testing services including Dynamic Load Testing with an APPLE drop weight system, CAPWAP® Analyses to simulate static load testing, Drilled Shaft Base Cleanliness Evaluations, Thermal Integrity Profiling, and Static Load Testing on CFA piles. The project was considered monumental as it was the Ohio DOT's first time utilizing Dynamic Load Testing on a CFA pile. Read more
In 2020, GRL Engineers were contracted to perform testing on the Mile-Long Bridge located in Willow Springs, Illinois. Various testing methods were performed to assess the concrete integrity including Crosshole Sonic Logging, Thermal Integrity Profiling, and Data Analyses.
GRL Engineers took on an investigative project on the North Madison Substation in Wisconsin, to analyze acceleration and stresses in non-uniform piles during vibratory driving. The test involved Dynamic Pile Monitoring using a Pile Driving Analyzer (PDA) and the PDI-VIB Program.
