Establishing a comprehensive understanding of the soil and foundation was pertinent to the construction of the new Corvallis Van Buren Bridge. GRL Engineers were hired to analyze the foundation’s capacity using Bi-Directional Static Load Testing services. Additionally, Drilled Shaft Verticality was assessed prior to concrete installation. Thermal Integrity Profiling was utilized to monitor concrete curing and identify potential anomalies. Crosshole Sonic Logging was utilized when a thermal wire did not record data.

During a bi-directional static load test, the deep foundation element is instrumented to provide information about soil and foundation response to load. GRL cells can be installed in drilled shafts, augercast piles, drilled displacement piles and barrettes.

In this case study the $118 Million interchange reconfiguration was initiated to create a smoother, more efficient transition for heavy airport traffic flow on the Beachline Expressway.

GRL Engineers performed Thermal Integrity Profiling on the Seattle Center Arena, also known as the Climate Pledge Arena, the world’s first net zero certified arena.

GRL Engineers proposed Dynamic Load Testing on micropiles for the Van Wyck Expressway. The initial micropiles were damaged and Thermal Integrity Profiling was utilized to assess the integrity of the alternate piles. CAPWAP Analysis was also provided after testing to further evaluate static pile capacity.

Static Load Tests provide pertinent information regarding load capacity, movement, and elasticity. GRL Engineers offers axial compressive testing, axial tension testing, and lateral load testing.

GRL 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.

This program utilized a variety of testing methods. Static Load Testing was performed as well as Dynamic Load Testing using an APPLE system. Thermal Integrity Profiling and Low Strain Integrity Testing services were provided to assess concrete. CAPWAP Analyses were utilized to review capacity.

GRL Engineers use the Shaft Area Profile Evaluator (SHAPE) to determine drilled excavation area and verticality prior to concrete pour. With remote testing capabilities, verticality assessments can be made quickly from any location.

APPLE Load Testing Systems are available with a range of modular weights from 1 to 80 tons.

APPLE Dynamic Load Testing Systems are an attractive alternative to static testing of any deep foundation and are designed to activate a large range of test loads.

GRL’s APPLE dynamic load testing systems can be configured for a wide range of weights and delivered to projects anywhere in the continental USA.
