Our Series on the 2022 New York City Building Code, Chapter 33, Safeguards During Construction or Demolition Continues…
Introducing BC 3304.4.1 Support of Excavation Construction Documents
The existing code allowed any registered design professional to prepare support of excavation drawings. The revised code allows only a registered professional engineer to prepare support of excavation drawings where the excavation will be carried to depth greater than 20 feet.
In addition, some of the exemptions to the requirement for design drawings have been modified. To take advantage of the exemptions, the excavation must now be less than 5 feet deep but above the water table; or if greater than 5 feet, must be 5 feet from adjoining foundations/streets and must not exceed 20 feet, with the sloping of the resulting embankments not steeper than 34 degrees (1.5 horizontal to 1 vertical) or sloped in accordance with a design professionals’ recommendations.
The trench box exemption now requires the manufacturer’s specifications to be on site. This had been the policy but is now codified.
Although the existing code contained some limitations on the sloping and benching of excavations, a new more detailed section with table has been provided in the revised code, linking slope to soil type (A, B, C). The exemption to sloping for rock (of Class A, B, C) has been carried over, provided a geotechnical report substantiates the safety of the cut.
