Select the Construction Class for the occupancy. The standard Marshall & Swift Construction Classes are:
D Wood or Steel Stud Framed Exterior Walls
Note: All classes are not available for all occupancies. Once you have selected an occupancy, only the classes available for that occupancy display. Also, if after selecting a class you change the occupancy to an occupancy for which the class is not available, Segregated Estimator automatically changes the class to the first available one for the new occupancy.
