8.0 See Section 2, "General Requirements for Shoring".
8.1 Rolling shore brackets shall have allowable loads based on tests conducted by the manufacturer and witnessed
by an independent testing organization.
8.2 Design of shoring layouts using rolling shore brackets shall be based on allowable loads which were obtained
using the manufacturers' tests, and at least a 2.5 to 1 safety factor.
8.3 The shoring is to be approved by the engineer of record, relative to:
a. Method used to anchor shoring bracket to column or wall.
b. Eccentric load, on column or wall, caused by shoring bracket load.
8.4 All rolling shore brackets shall be inspected before erection by the contractor who erects the equipment.
8.5 Rolling shore brackets shall not be used if any component is excessively rusted, bent, rewelded beyond the
original factory weld locations, has broken welds, or other defects.
8.6 All components shall be in good working order and in a condition similar to that of original manufacture.
8.7 When checking the erected rolling shore brackets with the shoring layout, the spacing between brackets and the
size of the deck form being supported shall not exceed that shown on the layout.
8.8 The rolling shore brackets shall be plumb and level and tightened to the mounting surface with the manufacturers'
designated size and grade of bolts/rods or inserts prior to concrete placement.
8.9 Check to see that the rolling shore bracket is not extended out from its vertical support face in excess of the
manufacturers' recommendations. Means must be provided to prevent lateral movement of the deck form during
roll-out.
