For existing buildings, Emergency Backup Power system installation or modification work must comply with the NYC Zoning Resolution, Construction Codes (Building, Fuel Gas, and Mechanical), NYC Electrical Code, NYC Fire Code and NYC Energy Conservation Code. Per the 2014 Administrative Code Section 28-101.4.3 and 2016 ECC 101, additions, alterations, renovations or repairs to an installed system shall conform to what is required for new installations without necessarily requiring that the existing installation comply with all requirements of this code. Alterations or repairs shall not cause an existing installation to become unsafe, hazardous or overloaded.

Guidelines for Submission of Emergency Power Backup Systems Project Plans

Prior to submitting the DOB permit application, the Applicant ’s design of the proposed emergency power system should comply with all zoning regulations and construction codes for existing rooftop, ventilation, structural, and electrical components. Based upon the complexity and scale of the project, the information provided on the application documents should show a clear description of the required project scope of work.

Although the DOB does not mandate the organization and style of construction documents, in order to facilitate the plan examination process the guidelines outlined in this chapter present a consistent approach to preparing Construction Documents. In many cases, projects require documenting existing systems, which must be identified differently from new systems.

Complete Submission of Emergency Power Installation Work Drawings

The drawings represent work that is closely coordinated with multiple disciplines, such as architectural, structural, electrical, plumbing and mechanical. For details essential for a complete submission of application drawings, see NYC Administrative Code 28-104.7 and 1 RCNY 105-02:

Construction Documents. Drawings that convey essential information, such as floor layout with dimensions, elevations and building sections, schedules, and riser diagrams, structural support and details, are necessary. The Title Sheet should, with clear graphics, define the project location with its vicinity. The applicable Building Codes and Notes should be stated on all appropriate drawings. A List of Drawings is recommended to clearly identify all unique systems in the design.

Title Sheet. Should clearly define the project location, Block and Lot Number, Zoning District; Drawing List; Flood Zone Compliance when located in a Special Flood Hazard Zone; basic building description, such as building use, height, construction and occupancy class; and scope of work.

Site Plan. Clearly show the size and location of the lot; show all existing structures on the zoning lot with all necessary dimensions. If the project work involves exterior or underground locations for boiler or fuel storage, such as a vault, underground storage tank, fill-pipe fuel terminal, these items must be clearly documented.

General Notes. Clearly define, among others, the Tenant Protection Plan, structural evaluation notes, Special and Progress Inspections, and Energy Analyses.

Floor Plan. Clearly show the location of the proposed Emergency Power System and other related support structures, such as dunnage, vibration isolators, equipment, exits, and clearances.

Roof Plan. When the scope of work incudes installation of equipment on the roof a Roof Plan is necessary to indicate clearly the location and layout of the proposed Emergency Power System, dimensioned FDNY rooftop access clearances, and rooftop obstructions such as bulkheads, skylights, plumbing pipes, and mechanical equipment. Clearly note the locations of roof drains.

Elevations. Clearly show the location of exhaust or fresh air intake vents, dampers, exhaust duct extensions, terminations and any relevant equipment, and compliance with zoning height/setback requirements.

Detail Drawings. Show in magnified form significant information required to communicate the scope of work clearly. Identify enclosure details, mounting details, structural analysis, and equipment specifications.

Plumbing Riser Diagrams. If the project involves alterations to existing or installation of new piping and/or gas supply, a riser diagram must show these details.

Electrical Riser Diagrams. If the backup power system installation is of 1,000 KVA or more, an Electrical Diagram must be provided that outlines the service switchgear, transformer(s), and transfer switches. These systems require NYC Electrical Advisory Board (EAB) review for its approval of the installation.

Submission of Construction Documents

1. Drawings: The emergency power drawings should reflect clear scope of work and include all affected systems. Examples of this are as follows:

Recommended Drawing Designators
A: Architectural: Mandatory designation for architectural work.
S: Structural: Mandatory designation for structural work.
M: Mechanical: Mandatory designation for mechanical work.
E: Electrical: Mandatory designation for electrical work.
P: Plumbing: Mandatory designation for plumbing work

2. Required Documents/Submissions. Based on the scope of the project the following submissions may have to accompany the drawings at intake:

Chimney inspection report (if required)

Tenant/Occupant Protection Plan (only if applicable)

SRO MD Anti-Harassment checklist

Changing from central heat to individual heat (Leg)

MTA requirements or restrictions

Special Flood Hazard Area (SFHA)

3. Plan Review or Audits for Approval/Acceptance. Following submission, the application is assigned to a Department Plan Examiner for review. If the project is Professionally Certified, the application may be audited. A plan review or audit of the submission by the Plan Examiner or Auditor may result in either approval or disapproval, or an acceptance or failure, respectively. Following plan examination disapproval or audit failure, a List of Objections is sent to the Applicant-of-Record and Owner. Objections must be resolved during scheduled meetings with DOB Plan Examination or Audit Staff after which the application is approved or accepted.

4. Post Approval Amendments. Any changes to approved scope of work that is significant and substantive will require submission of revised plans for Post Approval Amendment (PAA). Approval for an amendment must be obtained before the work or equipment is completed. Changes that are not substantive do not require a PAA; however these changes must identified on an Additional Information 1 Form (AI-1), shown on the documents and included in the ‘As Built’ (Record Drawings) submission at the end of the project (§28.104.3)

Substantive changes require a PAA if the following criteria are met:

Changing the location of the system, change of fuel source, clearances, and/or egress

5. As Built Submission. All changes must be submitted in an ‘as built’ drawing at the end of the project.

Special and Progress Inspections

Emergency Backup Power installations require, per the Building Code, that certain Special and Progress Inspections be performed during and at the end of construction; see the table below. Prior to Approval, the Applicant is required to identify all required Special and Progress Inspections. Prior to DOB permit issuance, the Owner must engage a registered Special Inspection Agency (SIA) who takes responsibility for the Special and Progress Inspections. Applicants may perform these inspections if they are also registered as a SIA.

Final electrical inspection

Final construction inspection for sign-off

An Inspector verifies that the field conditions match the approved documents for both installation of panels and equipment. An Inspector also confirms that the equipment is installed per the electrical diagram, which includes connection to the main electric service panel. For plumbing work, the Contractor may self-certify in lieu of a DOB inspection

Inspection Requests

The Department’s online portal for scheduling appointments for required DOB inspections must be used. DOB NOW provides robust online accounts, making it easier to submit applications, make payments, schedule appointments, check the status of an application or inspection, pull permits, and make renewals.
