Featured Projects

Concrete Integrity Testing on the Tri-State Tollway Mile Long Bridge

In 2019, the new foundations for the NB bridge began - a project that would replace the Mile-Long Bridge located on I-294 in Willow Springs, Illinois. GRL Engineers were brought onto the job in 2020 to apply various testing methods to assess the concrete integrity of the new foundation supports. Read More

Dynamic Measurements of Vibratory Driven Composite Steel Piles Subjected to Axial and Bending Forces

An investigative project by GRL Engineers was analyzing acceleration and stresses in non-uniform piles during vibratory driving. Read More

Dynamic Pile Monitoring of Cast-In-Drilled-Hole (CIDH) Test Piles

The Case Pacific Company in California contacted GRL Engineers to help collect high-strain dynamic measurements on two Cast-In-Drilled-Hole piles. The project in Oakland at the 1100 Broadway Avenue, was initiated to update... Read More
