First Solar is a leading American solar technology company and global provider of responsibly produced eco-efficient solar modules advancing the fight against climate change. Their newest warehouse and office are a whopping 2.4 million square feet! To put it another way – it’s a half-mile walk from one end of the warehouse to the other. Better buy some good shoes!

Lee Company was tasked with the mechanical and plumbing, specifically for the office space and only a piece of the warehouse building. The job was super specific, just like the general contractor wanted, because this project was so massive no one wanted to overload a single contractor.
