D50 ELECTRICAL


SYSTEMS REQUIREMENTS
ELECTRICAL TEMPLATE 12/08
 
Instructions for using this template: There are template files for each UNIFORMAT Level 2 Group Elements. This template is for Group Element D50-ELECTRICAL. Text such as this is hidden text that will not print when the hidden text box in "Print/Options" is un-checked.

The Electrical Designer must edit this template for the requirements of the project and wherever brackets [ ] appear. The Electrical Designer shall use UFC 3-500-10N when determining electrical system requirements.
 
It is acceptable to place all required information in the main element (such as D5010) and delete the sub-elements provided in this template.
 
The SYSTEMS REQUIREMENTS are intended to define items that are required throughout the facility or on a system wide basis that is common to several rooms. Room-specific requirements are defined in the ROOM REQUIREMENTS section. Coordinate with the lead programmer for ROOM REQUIREMENTS. Delete all building elements that are not required for the project. If additional elements or sub-elements are required for the project that do not appear in the template, refer to the NIST UNIFORMAT II publication for additional building element numbers and descriptions. The Uniformat II Work Breakdown Structure can be found at www.wbdg.org/ndbm/. Coordinate with the PERFORMANCE TECHNICAL SPECIFICATION SECTION D50 (Section D50) to ensure that performance requirements are provided for all of the Building Elements listed here and that paragraph numbering matches.
 
There may be rare occasions when prescriptive specifications may either be edited and included in Part 5 of the RFP or required in Section D50 to be edited by the Contractor’s Designer of Record.  In both cases, the Engineering Systems Requirements (ESR) must include references to these documents.

ESS requirements vary from project to project and differ at each activity.  Installation of an ESS including designating protected areas/zones shall be indicated in the Project Program.  If an ESS is required, coordinate requirements with Project Manager and Base and Regional Security Personnel.
 
The following is provided for guidance only and should be edited accordingly to suit each project. ESS shall be fully coordinated and defined by the RFP writer and not left up to the design builder.
 
For Marine Corps projects, provide infrastructure support only.  Coordination with Commandant Marine Corps (CMC) is required.

An Electronic Security System (ESS) is the integrated electronic system that encompasses one or more of the following subsystems; access control system (ACS), intrusion detection system (IDS), and closed circuit television (CCTV) systems for assessment of alarm conditions.

Do not size the generator but rather provide loads and voltages of dedicated equipment or circuits. Delete when not applicable.

[Provide an emergency generator for power for the following loads and equipment: [     ], [      ], [      ]. The generator shall provide [       ] [minutes] [hours] [days] of emergency power.]

NOTE:  UPS generally is not provided under construction but when required by the Activity should be provided for critical loads only and be limited to small (15-50 kVA) stand alone units based on scope of design build facilities addressed by this RFP. Large systems, paralleling schemes, redundant systems etc typically do not fall under the scope of the Design Build scenario. Small, individual, under desk type units are typically provided by the Government as collateral equipment and are not part of construction dollars. RFP writer shall determine when and if UPS power is required and edit accordingly. When complex systems are required, this section will require extensive modifications. Coordinate this section with the emergency generator section when both are required. Delete when not applicable.

NOTE:  RFP writer shall make preliminary calculations and determine if a lightning protection system is required in accordance with NFPA 780 Appendix L "Lightning Risk Assessment".  Beginning in 2000, NFPA 780 changed its assessment procedure to use a "Lightning Flash Density Chart" in lieu of the "Lightning Frequency Isoceraunic Chart" used in previous versions, and includes recommendations of when to include a lightning protection system. Systems covered by this specification will generally be described in Chapter 4 of NFPA 780 "Protection of Ordinary Structures".  A "UL Lightning Protection Inspection Certificate certified to UL 96A" is now required in lieu of a “UL Master Label” when a system is provided.
 
Include the bracketed option(s) when additional buildings or systems will require work in order to qualify for the Certificate.  Delete when not required.

D509090 OTHER SPECIAL SYSTEMS AND DEVICES


NOTE:  400-Hertz power requirements shall be determined by the RFP writer based on user requirements. Aircraft power requirements have changed drastically recently (kVA and power quality requirements have generally increased) and values and requirements indicated in UFC 4-121-10N and UFC 3-555-01N may not be accurate. New aircraft may contain an individual power monitor that disconnects the aircraft from ground power when voltages exceed very specific requirements and the trend is to provide individual stand-alone units per each aircraft in lieu of the original distribution system as called for in the UFCs. Several new aircraft (E2C Hawkeye 2000 for instance) now also require two separate power sources due to the power monitor requirements. RFP writer shall include specific equipment requirements including number of units, kVA, requirements, etc.
