Revisions to the NYCSCA Standard Specifications

HVAC Sections

The following revisions were made to the Division 15h NYCSCA Standard Specifications. The remainder of the specifications generally being revised due to implementation of the new code will follow under future

Specification Bulletin SP09-03, which is to be released shortly.

Items denoted A# are applicable to all Capacity and CIP Projects.

Items denoted B# are applicable to all Capacity Projects but not to CIP Projects.

Items denoted C# are applicable to CIP Projects but not to Capacity Projects.

The Applicability Table at the end of this Bulletin indicates whether changes are applicable to all projects or just to those filed under the 2008 NYC Construction Codes.

Due to the complexity of many of the changes with the implementation of the 2008 NYC Mechanical Code and in order to assist in understanding of the changes, the descriptions are much more detailed than a typical

Bulletin and thus they are being presented in a separate Bulletin. Most projects affected by many of the changes are in design since mandatory implementation only went into affect in July 2009. If there are projects that are beyond the design/bid phase, Bulletins should be issued for items not addressed independently of the official specification changes that would otherwise lead to non-code compliant conditions. In addition, Bulletins should also be issued for non-code issues judged to be required for construction phase implementation as indicated in the Applicability Table at the end of this Bulletin.

The Project Design Professional shall use the revised specifications as required and include them in the project specifications.

Projects that are presently in Bid (prior to bid opening):

The Project Design Professional shall revise the Project Documents to include the revisions as required, and issue to the bidders as an Addendum through the Design Project Manager (DPM).

Projects that have Bids opened, but the Notice to Proceed has not yet been issued:

The Project Design Professional shall revise the Contract Documents to include the revisions as required, and issue as a Change Order Bulletin through the Project Officer as soon as the Notice to Proceed is issued if change requires such. As most projects affected by many of the changes are in design since mandatory implementation only went into affect in July 2009, if there are projects that are beyond the design/bid phase any Bulletins should only be issued if the item was not addressed independently of the official specification changes and will lead to a non-code compliant condition.

Projects where the Contract Notice to Proceed has been issued and the Project is in Construction:

The Project Design Professional shall revise the Contract Documents to include the revisions as required and issue as a Change Order Bulletin through the Project Officer if change requires such. As most projects affected by many of the changes are in design since mandatory implementation only went into affect in July

2009, if there are projects that are beyond the design/bid phase any Bulletins should only be issued if the item was not addressed independently of the official specification changes and will lead to a non-code compliant condition. For non-code related items, designer is to determine if work is installed before issuing.
