                As a Project Executive for a major electrical contracting firm, I am always looking for ways to increase productivity and reduce labor expenses. I was recently assigned 3 major projects in one of the most well-known cities in the world. Each project started at the same time and the temporary light requirements were enormous. I reached out to Thompson Brown Inc. for a solution. They quickly presented a solution to prefabricate the temporary light stringers for us, not only saving valuable man hours on the site but allowing us to light up the work site much quicker."
