We also perform engineering site visits and can produce structural and foundation drawings! Also, use our free Contractor Calculators to calculate the Yards of Concrete you need for your foundation or the amount of Plywood and Joists you will need! Most of our joist recommendations come from Weyerhaeuser who produces TJI Trus Joist products.
