Software for Architects & Specifiers

designIT® for Commercial Floors is a software tool for all building practitioners for the design of Futurebuild's engineered wood products for commercial, industrial and other heavily loaded floors.

Quick and simple to use yet deceptively powerful software, designIT for commercial floors is useful for the selection of beam sizes without the need for the exercise of professional engineering judgment.
