Figure 9-1.—Two 20- by 48-foot rigid-frame, preengineered buildings erected end to end.FOUNDATIONSIn addition to the usual reasons for stressing theimportance of a square and level foundation, there isanother reason peculiar to the erection of a pre-fabricated structure. Prefabricated parts are designedto fit together without forcing. If the foundation iseven slightly out of square or not perfectly level, manyof the parts will not fit together as designed.Continuously check the alignment of the anchor boltsprior to, during, and after concrete is poured.PREELECTION WORKA lot of preliminary work is necessary before theerection of a PEB can begin. After the building site isselected, prepare to pour the foundation and slab.Before concrete for the foundation piers can bepoured, templates for the anchor bolts are placed on theforms, and anchor bolts are inserted in the holes. Thethreads of the bolts are greased and nuts are placed onthem to protect the threads from the concrete. After alast-minute check to ensure all forms are level and theanchor bolts are properly aligned, concrete is placed inthe forms and carefully worked around the bolts so theyremain vertical and true.While the foundation is being prepared, other crew-members are assigned various kinds of preliminarywork. This work includes uncrating material and inven-tory, bolting up rigid-frame assemblies, assemblingdoor leaves, and glazing windows. When all prelimin-ary work is properly completed, assembly and erectionof the entire building are quicker and you have fewerproblems.All materials, except paneling, should be uncratedand laid out in an orderly manner so parts can be easilyfound. Don’t uncrate paneling until it is ready to install.When the crates are opened, don’t damage the lumber;you can use it for scaffolding, props, and sawhorses.After the building foundation has been prepared,and where practical, building materials should beplaced on the building site near the place where theywill be used. Girts, purlins, cave struts, and brace rodsshould be equally divided along each side of the foun-dation. Panels and miscellaneous parts that will not beused immediately should be placed on boards on eachside of the foundation and covered with tarpaulins or9-2
