4.8.3 Sizing

The size and quantity of pin piles will vary depending on the size of the structure, number of stories, and weights of materials used. Pin piles should be sized to resist both gravity (dead, live, and snow) and lateral loads (wind and seismic). Additional design considerations include uplift resistance for seismic overturning forces. Sizing of minimal excavation foundations is performed by structural and geotechnical engineers on a site-by-site basis.
