Gary C. Hart, Ph.D., President and Senior Consultant of Hart Consultant Group, and a Professor of Civil Engineering at UCLA, conducted an independent review of Proto II™ Wall System engineering. Dr. Hart's background is especially strong in areas of structural engineering requiring practical application of highly technical analytical methods and research. He is expert in masonry engineering design and his works have contributed greatly to the state-of-the-art in concrete masonry engineering. Dr. Hart's comments:

"…it's an innovative new product that I believe provides a valuable design alternative…"

"The Proto II™ design is based on sound structural engineering principles…"

"…the design examples provided by Mr. Paul Scott, a Structural Engineer in California, are excellent. I reviewed Mr. Scott's calculations and agree with them."

"I would not hesitate to use this wall system on one of my projects or to recommend it for use…"

"Mr. Scott has clearly demonstrated the design trail that must be followed to meet the intent behind the prescriptive requirements in the Uniform Building Code."

"…a very outstanding new structural system."
