"I have been in the construction industry for 25+ years, and have never seen anything quite like the UpGrade Clear Span Building by Whitley Manufacturing. I recently had the opportunity to erect one of these buildings and was thoroughly impressed. We took the project from a slab to almost weather tight in right around 10 hours. 
During my career, I have been involved with conventional wood framing, steel framing, precast concrete, tilt-up concrete, and virtually every other conventional method of construction. None of which can be completed as quickly and efficiently as the UpGrade Clear Span Building™. 
If your time equals money, this system would worth a fortune to you."
