1802.5.1 Bedrock Support

NYC Building Code 2014 > 18 Soils and Foundations > 1802 Geotechnical Investigations and Material Classifications > 1802.5 Soil and Rock Sampling > 1802.5.1 Bedrock Support
JUMP TO FULL CODE CHAPTER
Where the foundation design relies on rock to support footings, piles or caisson sockets, a sufficient number of rock corings shall extend at least 10 feet (3048 mm) below the lowest level of bearing to provide assurance of the rock soundness. Where foundations are to rest on bedrock and such rock is exposed over a part or all of the area of the building, borings are not required in those areas where rock is exposed, provided the following requirements are met:
  1. The presence of defects or the inclination of bedding planes in the rock are of such size and location so as not to affect stability of the foundation.
  2. The foundation is not designed for bearing pressures exceeding those permitted in Table 1802.3.
