Carry out site investigation as described for dead shoring.
Mark out and cut mortises and housings on a wall plate.
Set out and cut holes for needles in an external wall.
Excavate to a firm bearing subsoil and lay grillage platform and sole-plate.
Cut and erect rakers, commencing with the bottom shore. A notch is cut in the heel so that a crowbar can be used to lever the raker down the sole-plate and thus tighten the shore (see below figure). The angle between sole-plate and shores should be at its maximum about 89° to ensure that the tangent point is never reached and not so acute that levering is impracticable.
Fix cleats, distance blocks, binding, and, if necessary, cross-bracing over the backs of the shores.
