The Corvallis Van Buren Bridge, originally built in 1913, was reconstructed to meet modern seismic standards. The new foundations underwent rigorous testing to assess concrete integrity, shaft verticality, and load-carrying performance. GRL Engineers performed these tests to determine compliance with design requirements. Read the full case study on the GRL website.

GRL Engineers provided deep foundation testing for many of the installed piles utilized in the Port Sulphur Plaquemine foundation. Low strain integrity testing combined with dynamic load testing provided insight on the structural integrity of the constructed piles. Read the full case study at https://lnkd.in/e3Cr-c8q.

To achieve cleaning once drilling is complete, a cleanout bucket is typically used to remove any material unsuitable for end bearing support. Bottom inspection is then performed, often by lowering a camera down the bore hole, a procedure that gives a rough idea of the thickness of any debris left at the bottom. To improve the inspection method, GRL Engineers utilize a Shaft Quantitative Inspection Device (SQUID) to measure force and displacement at the bottom of a drilled hole to quantitatively assess the cleanliness or the debris thickness of the excavation bottom.

Toombs County in Georgia took on a $60+ million-dollar bridge project to offer improved traffic flow over the Altamaha River. In 2020, GRL Engineers were brought on to perform bi-directional static load testing on a non‑production drilled shaft that would help assess the load capacity of the replacement bridge. Working with United Infrastructure Group, Inc. and Lee & Sims Drilling Services, Inc., 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. Read the full case study at grlengineers.com

50% faster. 40% lower cost. On a large industrial facility in Wyoming, the team replaced conventional drilled shafts with large-diameter ACIP piles, and GRL’s comprehensive load testing helped confirm the switch. Read how the project came together.

Drilled shafts were the plan. ACIP piles were the answer. On a large industrial facility in Wyoming, switching to large-diameter ACIP piles saved 50% on schedule and 40% on cost, backed by GRL’s comprehensive load testing. See the full project story.
