The scope of this project was so daunting, Commercial Window Shield was the only bidder. Multiple film installation companies attended the pre-bid walk through in Vanderbilt Hall, located inside the world famous Grand Central Terminal, and left before the tour was completed. With Commercial Window Shield’s long history of completing challenging and difficult projects, GEM Construction, the project’s general contractor, was comfortable having us handle the project. The cleaning of the 454 windows, left untouched for decades, was a significant and delicate task but required to make sure the security window film we installed would adhere to the glass. The project was completed as planned and on time, to the satisfaction of GEM.
