Description

• Projects in this scope area may include installing new electrical service switches, switchboard, distribution panels, panelboards, motor control system, transformers, risers, feeder conductors’, conduits, and panels; installing new grounding system, panelboards, service switches, switchboards, disconnect switch, receptacles, over current protection devices (OCPD), Surge-protector (SPD) and motor control equipment; and installing dry type or liquid type transformers. The full, detailed scope of work for this project including any additional work areas will be updated here after alignment with project stakeholders through scoping and design activities. 

Baseline

• Power Distribution  
• Electric Service Description/Design Approach:  
• A. General  
• 1. During the Schematic Design Phase, the design engineer needs to send a service request/load letter to the utility company. This request should ask about the available service voltage, utility short circuit current and impedance, charges, and any other requirements. The request should also specify the desired voltage and point of entry. Additionally, the engineer should provide a copy of the site plan along with all available geotechnical, architectural, and structural information, including the following documentation. Drawings should be submitted in AutoCAD format, and when available, copies of the approved drawings by the Department of Buildings should also be included. 
  • a. Legal Survey of Property (and/or with sidewalk elevations in the area of proposed vaults)  
  • b. Builder’s Paving plan  
  • c. Environmental Study for the site  
  • d. Soils report with boring data  
  • e. Site Plan with all utilities  
  • f. Foundation drawings  
  • g. Architectural drawings for the building in the area of proposed vaults with floor elevations  
  • h. Structural drawings for the building in the area of the proposed vaults  
  • i. Details of any special construction at proposed vault location such as planting areas, sidewalk snow melting devise, street lights, hydrants, etc.
• 2. The standard voltage is typically 120/208 volts, but in certain situations, 265/460 volts may be an option and is preferred for electrification projects. When the standard voltage is 120/208 volts, the engineer needs to assess whether it’s cost-effective to increase the voltage to 265/460 volts for lighting and motor loads. The 120/208 volts should be used for receptacles outlets and other systems. 
• 3. When the available voltage is 265/460 volts, the engineer must consider connecting the lighting and motor loads and stepping down the voltage to 120/208V for receptacles and other systems.  
• 4. In either case, the design engineer must conduct an economic analysis to justify the chosen service voltage and design option.  
• 5. If transformers (both step-up and step-down) are used in a project, the electrical engineer must coordinate with the mechanical discipline for the ventilation requirements.  
• 6. If a step-up transformer is provided, the switch on the primary side of the step-up transformer must be carefully selected and specified to accommodate the prevalent high in-rush currents. The transformer in-rush current shall be limited to 10 times rated current. 
• B. Electrification Projects 
• 1. All requirements shall apply as for a new service. 
• 2. The electrical designer is responsible for designing a new electrical service and determining the point of entry (POE) while considering existing conditions, constructability, and the phasing of the new service into the existing building. The designer should evaluate the existing electrical service by engaging electricians and switchgear experts/manufacturers during the design phase to determine existing conditions and how to reinforce the service based on utility company service regulations. 
• 3. Preference is to have developer agreements with utility company to control scheduling for the project.  
• 4. The utility company load letter shall indicate developer agreement would be preferred if new vault is being ruled at the requested POE.  
• 5. The backup electrical service size for the heat pumps is to be based on 75% of the total size of all the heat pumps based on functioning energy recovery wheel at 50% efficiency. 
• C. NYCDOT Requirements 
• When a transformer vault is required by the utility company, the design engineer shall establish a reference number with the NYC Department of Transportation (NYCDOT) Office of Permit Management and meet with NYCDOT to secure vault grating location approvals. This meeting with NYCDOT shall take place during the Design Development Phase. Forms and information can be obtained at NYCDOT 
• Design and install electrical systems so that, in case of emergency, their operation will not be grossly affected. 
• Corridor, Lobbies Places of Assembly, Parapet, Pipe Chases and Roofs receptacles for maintenance, non-switched 20 Amp, 125 Volt, specification grade, duplex type, shall be provided so that all areas in the spaces are accessible by a 50’ extension cord. Parapet mounted receptacles shall be ground fault circuit interrupt (GFCI) protected. 
• Offices Receptacles for which the office computers and printers will be plugged into shall be switched 20 Amp, 125 Volt, specification grade, duplex receptacle. 
• In apartments where the electrical panel is installed above the kitchen sinks, the panel locations should comply with the requirements of the NYC Electrical Code and NFPA 70 National Electrical Code (NEC). 
• Install arc-fault circuit-interrupter protection devices in all apartments. 
• Evaluate electrical panel at each residential unit for spare capacity. Assume electrical upgrades to each residential unit electrical panel as necessary to support the electric heating/cooling, electric range cooking, and other scope item upgrades indicated in this document, accommodating power requirements. [COMPMOD] 
• Evaluate existing electrical service spare capacity. Assume electrical upgrades at building infrastructure level to accommodate the additional electrification related loads indicated in this document, including new electrical risers to each residential unit to accommodate the above. [COMPMOD] 
• Confirm the condition of existing wiring. Replace any old, fabric-insulated cable with new PVC-insulated cable. [COMPMOD] 
• Confirm the condition of existing receptacles. Add new dedicated receptacles for the new equipment’s. Add new receptacles outlets required in kitchen and rooms in accordance with general provisions specified by NEC. Replace old/damaged receptacles with new. Replace old 2-prong receptacles with 3-prong (equipment grounded) receptacles. [COMPMOD] 
• Kitchen and bathrooms receptacles shall be 20Amp, 125 Volt, ground fault circuit interrupting (GFCI) protected duplex outlets as per NEC article 210.8 (NYC 2011 EC). [COMPMOD] 
• Replace existing branch circuits supplying outlets or devices installed in apartments with arc flash circuit interrupter (AFCI) means – as per NEC article 210.12. [COMPMOD] 
• Assume electrical upgrades, including electric ranges and cooling in all residential units. [PACT] 
• Include electrification-ready infrastructure where a development is not electrifying mechanical systems at the time of construction. [PACT] 
• Electrical work should be run behind the wall; wire-mold should be avoided where feasible. [PACT] 
• Where electrical wiring and wall finishes are being replaced, convenience outlets should be added throughout apartments, even where not required by code. [PACT] 
• Existing electrical equipment and cables should be organized or removed where no longer in service. [PACT] 

Stretch

• Install submeters as part of substantial electric upgrades. As NYCHA invests in energy conservation improvement. 
• Upgrade electrical panels and branch circuit wiring to support at minimum all-electric appliances as well as heating & cooling system and DHW system electrification at each residential unit. [COMPMOD] 
• Upgrade electrical distribution to support heating & cooling system and DHW system electrification, including service increase requests to the utility company (ConEd). [COMPMOD] 
• Locate switchgear above the flood elevation. [FR]

Description

• Emergency Lighting Independently powered or battery equipped light sources that are designed to activate when a power outage creates low-visibility conditions. 
• The NFPA standards require that the emergency lighting come on automatically. The lights must provide illumination for a minimum of 1.5 hours. The illumination should be at least an average of one foot-candle (10.76 lux) at foot level along the path toward the exit. The NFPA 110 and 111 address the standard requirements for Stored Electrical Energy Emergency and Standby Power Systems. These standards cover the performance requirements for emergency and standby power systems intended to provide an alternate source of electricity in buildings and facilities if the regular electrical power source fails. Systems include power sources, transfer equipment, controls, supervisory equipment, and accessory equipment needed to supply electrical power to the selected circuits.  
• Projects in this scope area may include repairing and/or replacing emergency lighting fixtures and exit lighting panels; installing electrical lines and backup power; and installing new plasterwork/drywall around lighting and signs. The full, detailed scope of work for this project including any additional work areas will be updated here after alignment with project stakeholders through scoping and design activities. 
• Exit signs shall be comply with Section BC 1013 of the 2022 NYC Building Code. The locations of exit signs will be indicated on the Contract Drawings by the Architect of Record. Means of egress should be clearly marked by illuminated exit signs with 8” letters to ensure that exits and path of egress are easily identifiable from any point in a corridor or Place of Assembly.  
• Exit signs placement should be so that no point in an exit access corridor is more than 100 feet or the UL1 listed viewing distance for the sign, whichever is less, from the nearest visible exit sign. Wall-mounted exit signs are preferred over pendant mounted exit signs. Pendant-mounted exit signs should be strictly limited to meet visibility requirements, and only used when additional wall-mounted units may not be suitable for the purpose.   
• Exit signs should be positioned at least five feet away from fire alarm strobes. 
• In buildings with a generator, exit signs must be connected to the emergency lighting panel through a transfer switch. 
• For buildings without a generator, exit signs should be equipped with battery packs and powered from the same source as the area lighting for the space, the exit signs shall be connected to a dedicated circuit with a locked breaker from the electrical power panel. 
• If mechanical rooms on the roof require two means of egress per Section BC 1006.2.2.1, exit signs are necessary outside of the mechanical room. If one of these exits is the exterior door to the roof, then an exterior exit sign on the exterior side of the stair bulkhead door is required to direct occupants back into the building to the required egress path. Exterior exit signs should be of the “weatherproof” type.
