Client Reviews

Innovative and Cost-Effective Project Solutions in Nevada

We have worked on several estimates and concepts with GSI over the last few years. Last spring, we had an opportunity to build a project with them. We received a handful of quotes, GSI was not only competitive, but they also provided a solution that significantly improved the project sequence and schedule. I think it is definitely worth your time to get to know James and their capabilities. I would also add that in many instances, their proposal is not apples to apples with competitors. Because of their unique approaches, oftentimes the earthwork scope can be decreased or made cheaper by using GSI.

On-Schedule and Professional Project Support in Virginia

As told by GSI Project Development Engineer: I was happy to take a call from [the Residency engineer] today and listened to him tell me how happy he was with the performance of Dylan and entire crew at the Garden Creek site. He had great things to say about the competence, work ethic, and professionalism of the whole team out there, and wanted to thank Dylan for the excellent communication as the project has unfolded. This is no small compliment, as this project began in a potentially negative atmosphere since the public thought we were behind schedule before we ever arrived! Nicely done, guys.
