The Department of Buildings has issued a Buildings Bulletin that establishes acceptance criteria for retractable-type horizontal cold aisle containment systems installed in information technology equipment areas. A copy of the Bulletin can be accessed here.

NYC DOB has developed Project Guidelines for Skilled Trades as a collaborative effort between the Department and industry partners for the purpose of highlighting the Construction Codes, Zoning and other regulatory requirements for project planning, execution and completion. The Guidelines provide information on tasks and responsibilities for the compliance of the construction project. While the Guidelines can be used for any stage of the project, it is suggested that using the Guidelines before the start of the project. The Project Guidelines contain general operational, administrative, and technical requirements related to construction project type. Specific and detailed technical aspects of each and every requirement for the design and execution of the proposed work are not included.
