1811.3.1 Capacity as indicated by resistance to penetration.
BC § 1811.3.1
Where subsurface investigation and general experience in the area indicate that the soil that must be penetrated by the deep foundation consists of glacial deposits containing boulders, or fills containing rip-rap, excavated detritus, masonry, concrete or other obstructions in sufficient numbers to present a hazard to the installation of the deep foundations, the selection of type of deep foundation and penetration criteria shall be subject to the approval of the commissioner, but in no case shall the minimum penetration resistance be less than that stated in Tables 1811.3(a) and 1811.3(b).
