About LTC

A New Way to Load Test

LTC’s founders, Robert Simpson, Aaron King and Jon Sinnreich, have combined direct experience with over 1,100 bi-directional static load tests on hundreds of projects around the world. Our expertise spans all aspects of project management and design, installation, testing and reporting, unique to bi-directional load testing (sometimes called “load cell” or “O-cell” test). Our primary mission is to help our clients design and implement bi-directional load testing projects as efficiently as possible, with the lowest possible risk and with the most favorable effect on schedule.

Our Philosophy

Having heard for decades that bi-directional load testing is great, but too expensive, we started LTC to resoundingly say that we agree. Deep foundation testing, like all industries must continue to evolve and rethink its value proposition. It is not enough to implement a full service load test program and justify the expense with possible savings down the road.

LTC offers a full spectrum of services, from the typical complete installation, testing and analysis of load tests package through training our clients to be able to independently self-perform BDSLT. Our goal is to empower our clients through a tailored level of service. The more our clients do, the more they save.
