Approved Extract

The ITAS Modular Building System is a re-usable steel building structure. The foundation footings are 600 mm x 600 mm excavated to a depth of at least 600 mm or the depth specified by an engineer. A solid concrete plinth foundation is then cast up to the ground level. A 16 mm diameter treaded rod for anchoring the building is encased in the concrete plinth. A 120 mm x 60 mm x 3 mm channel section is bolted onto the concrete plinth which then forms the formwork for the concrete floor. Onto the channel section an angle section (100 x 50 x 6 mm) is welded to which special folded steel plate columns are bolted at 1.2 m c/c spacing.

The column has special slots so that it fits over the upstanding leg of the angle.The external wall panels consists of folded 2 mm thick steel plate  stiffened by means of vertical top hat stiffeners (3 mm thick) fixed to the columns by means of a wedge system. On the inside the walls are lined with 15 mm gypsum board. The wall sections together with the columns form torsionally stiff walls around the perimeter of the structure.All the internal partitioning walls are 15 mm thick Rhinowall Dry Wall and in secure areas these are lined with 2 mm thick mild steel sheets.
