BC § 3307.6.4.10
Sidewalk shed founding shall be in accordance with the following: 1. The surface upon which the shed ultimately bears, such as the street, sidewalk, or ground, shall be capable of supporting the design loads of the sidewalk shed, including any item placed or stored upon the shed, without damage, settlement, or deformation to such surface.
2.Vertical members of the sidewalk shed shall bear upon base plates, mud sills, dunnage, or other adequate firm foundation. Such items shall be: 2.1. Made of suitable firm material. Supports such as barrels, boxes, loose brick, loose stone, hollow block, or other unstable materials shall not be used. 2.2. Capable of transmitting and distributing the load imposed by the sidewalk shed vertical member to the underlying surface. 2.3. Secured against movement in any direction. When consisting of several pieces of material, such as multiple wood blocks, the material shall be nailed or otherwise positively connected together to prevent dislodgement. When more than 1 inch (25 mm) thick, the material shall be nailed or otherwise positively connected to the sidewalk shed vertical member. 2.4. Installed in such a manner that the sidewalk shed vertical member is fully supported across all horizontal dimensions. 2.5. Installed in such a manner that no portion extends more than 1.5 inches (38 mm) beyond any horizontal edge of the sidewalk shed vertical member, or where it extends beyond such distance, is adequately guarded or barricaded to prevent tripping hazards; the installation of cross bracing, struts, and similar lateral support between the corresponding vertical members of the sidewalk shed will satisfy this requirement.
