202 Other structural applications of steel<br />

Fig. 5.32 ‘Stick-build’ site construction using wall studs and floor joists<br />

The main advantages of panel or sub-frame construction are:<br />

• speed of erection of the panels or sub-frames<br />

• quality control in production<br />

• reduced site labour costs<br />

• scope for automation in factory production.<br />

The geometrical accuracy and reliability of the panels and other components is<br />

better than with stick-build construction because panels are prefabricated in a<br />

factory environment. The accurate setting out and installation of foundations is a<br />

key factor to achieve rapid assembly of the panels and to obtain the maximum<br />

efficiency of the construction process.<br />

5.4.5 Modular construction<br />

In modular construction, units are completely prefabricated in the factory and may<br />

be delivered to site with all internal finishes, fixtures and fittings in place, as illustrated<br />

in Fig. 5.34. Units may be stacked side by side, or one above the other, to<br />

form the stable finished structure.
