Index–Galena Road Index, WA

As part of the critical effort to restore access between the town of Index and surrounding communities, a new bridge was required to reconnect the washed-out section of the Index-Galena Road. This reconstruction project called for deep foundation elements to support the structure in a remote and challenging location. To verify the structural integrity of these new drilled shafts, RAM GeoServices was brought in to perform Crosshole Sonic Logging (CSL) testing—a vital step in quality assurance for the bridge’s foundation system.

CSL is a non-destructive testing method that uses ultrasonic pulses transmitted between access tubes embedded in the concrete. By measuring the velocity and energy of these pulses, RAM was able to evaluate the internal consistency and strength of each 6-foot diameter shaft. Despite the remote setting, RAM delivered fast, accurate test results that confirmed the shafts had been constructed properly, allowing the project to move forward with confidence.

Our responsive approach and technical precision helped the construction team stay on schedule and within budget, reinforcing the reliability of the bridge’s foundation and contributing to the successful reconnection of this important transportation route.
