BC § 3307.6.4.4
Vertical members and beams of the sidewalk shed shall conform with the following: 1. Vertical members and beams shall be adequately braced and connected to prevent displacement or distortion of the framework.
2.The vertical members of the sidewalk shed shall be plumb, with a tolerance of L/100, with "L" measured as the distance from the ground to the first cross brace or bottom of the beam.
3.Vertical members shall not be placed into the street unless approved by the Department of Transportation and protected in accordance with Department of Transportation requirements.
4.Vertical members placed on the sidewalk shall not be placed closer than 18 inches from the face of the curb line.
5.Vertical members shall be placed at least 7 feet (2134 mm) from the edge of a curb cut or vehicular access point, or where placed closer, the vertical members nearest the curb cut or vehicular access point shall be protected against displacement by vehicles, or shall be identified with high visibility marking.
6.Vertical members, cross bracing, struts, and similar lateral support shall be placed in such a manner that the sidewalk, walkway, or pathway continues to comply with the requirements of Section 3307.2.6 and avoids interference in accordance with Section 3307.6.4.9.
7.Where the sidewalk shed is installed in conjunction with the construction of a new major building, a horizontal span of at least 10 feet (3048 mm), as measured down the length of the sidewalk, walkway, or pathway, shall be provided between all vertical members, except where a shorter span is needed to avoid the curb or obstructions in accordance with Section 3307.6.4.9; and all cross bracing, struts, and similar lateral support between vertical members shall be placed a minimum of 8 feet (2438 mm) above the level of the sidewalk, walkway, or pathway. However, cross bracing, struts, and similar lateral support between vertical members may be placed lower where it is installed to guard against a tripping hazard in accordance with Item 2.5 of Section 3307.6.4.10. Mast sections, box towers, or similar elements used as vertical members shall, for the purposes of this item, be considered to be one vertical member, provided its base does not exceed 24 inches by 24 inches (610 x 610 mm). In the alternative, a sidewalk shed that is of a model whose prototype won a design competition recognized by the city may be installed instead.
8.Where the decking of the sidewalk shed consists of light-transmitting plastic material, all cross bracing, struts, and similar lateral support between vertical members shall be placed a minimum of 8 feet (2438 mm) above the level of the sidewalk, walkway, or pathway. However, cross bracing, struts, and similar lateral support between vertical members may be placed lower where it is installed to guard against a tripping hazard in accordance with Item 2.5 of Section 3307.6.4.10.
