In that event, documentation must be provided in the calculations or by separate memorandum and reviewed by the City.

3.3.4 Loads

3.3.4.1 General

Loads to be considered shall include both lateral and vertical loads. Lateral loads are imposed by wind, seismic, soil and liquid pressures, and surcharge loads adjacent to walls.

Vertical loads include dead loads, live loads, snow load, suction and uplift loads imposed by wind, and uplift loads imposed by flood or groundwater. Equipment, large piping, and pipe thrust loads shall be accurately determined and incorporated into the structural design.

The following loads will be used for structural analysis of floor and roof systems in addition to any loading required by the building code:

1. Roof snow loads.
