NYC’s 2022 Chapter 33 Construction Code Revisions – BC 3304.12 – Slurry
The existing code section on use of slurry (bentonite or other) to support an excavation (drilled uncased shafts) has been revised, more for clarity than anything else.
The existing code section on use of slurry (bentonite or other) to support an excavation (drilled uncased shafts) has been revised, more for clarity than anything else.
The existing code required at least one means of egress from general open-cut excavations. The revision incorporates the OSHA requirement for multiple means of ingress/egress for trenches (trench definition: 4 feet or greater in depth and 15 feet or less in width) greater than 25 feet in length.
A common-sense guardrail exemption has been added to the revised code, allowing an adequate cover to be used in lieu of guardrails for wells, pits, shafts, or similar excavation.
Cold weather concreting practices and requirements for potentially structurally compromised buildings
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.
