NAVFAC Design-Build Model Request for Proposal - Standard Template

G40 SITE ELECTRICAL UTILITIES


SYSTEMS REQUIREMENTS
SITE ELECTRICAL UTILITIES TEMPLATE 09/22

Instructions for using this template: There are template files for each UNIFORMAT Level 2 Group Elements. This template is for Group Element G40-SITE ELECTRICAL UTILITIES. Text such as this is hidden text that will not print when the hidden text box in "Print/Options" is unchecked.

The Electrical Designer must edit this template for the requirements of the project and wherever brackets [ ] appear.  Use UFC 3-501-01 when determining electrical system requirements.

It is acceptable to place all required information in the main element (such as G4010) 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. Delete all 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 G40 (Section G40) 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 G40 to be edited by the Contractor's Designer of Record.  In both cases, the Engineering Systems Requirements (ESR) must include references to these documents.


NOTE:  Consider site electrical utilities relative to Part 2 UFGS Section 01 33 29, Sustainability Requirements and Reporting and UFC 1-200-02, High Performance and Sustainable Building Requirements.

SYSTEM DESCRIPTION


NOTE:  This specification is generally written around projects that will tap into existing telecommunications and medium voltage power systems. These systems may be overhead or underground. Generally the taps will be radial in nature but may require some switching and tie networks based on the existing system. It is not the intent of this ESR to provide extensive modifications, switching and circuiting to overhead and underground electrical systems. Provisions are included for simple networking but if major changes to the existing systems are required, this ESR and Section G40 will require extensive modifications.

This specification assumes a project will utilize installation-owned utility systems.  Should the utilities be owned by a non-installation entity, RFP Editor will need to coordinate with the utility owner for system requirements and make necessary modifications to this ESR and corresponding PTS G40.

Address scope and ensure the system description clearly describes the existing system, designated connection points, and any other information needed for the Contractor to understand the existing system and how the new project will connect to it.

[Demolish the existing [   ] system [and provide a new [   ].]

The site electrical utility system consists of all power and telecommunications and fiber optic cabling from the existing distribution system point of connection including all connections, accessories and devices as necessary and required for a complete and usable system. This section covers installations up to within 5 feet (1.5 meters) of new (or existing) building location.

GENERAL SYSTEM REQUIREMENTS

Provide an Electrical System complete in place, tested and approved, as specified throughout this RFP, as needed for a complete, usable and proper installation.  Install all equipment in accordance with PTS Section G40 and the manufacturer's recommendations. Where the word "should" is used in the manufacturer's recommendations, substitute the word "must".

Provide site electrical utilities systems and components that support project sustainability goals of Part 2 UFGS Section 01 33 29, Sustainability Requirements and Reporting.


NOTE:  Requirements for Government Furnished Equipment (GFE) are provided in ESR E10, Equipment.

G4010 ELECTRICAL DISTRIBUTION


NOTE:  Edit voltage characteristics to match voltages for the project. All medium voltage work will generally be exterior to the facility and will not extend into any buildings. If medium voltage is required inside a building, ESR D50 will require extensive editing.
 
Coordinate with local activity utility branch to determine the closest point of connection for the electrical distribution. Preliminary load calculations will be required by the RFP writer for the activity to assure that the existing system will not be overloaded. A site plan and simple one line diagram will generally be required to direct the design builder and coordinate properly with the existing electrical power system if switching and or tie networks are involved.

Connect to the existing [         kV], [480Y/277 volt] [208Y/120 volt] [120/240 volt], [three] [single] phase, [four] [three] wire, [60] [50] Hertz electrical power system.

NOTE:  Provide available fault current when it is known. Use second option below for all other cases. Assuming an infinite bus will assure a conservative design but may result in connections of medium voltage equipment being oversized or inadequate for the conditions. Consult with the activity. When accurate data is not available, choose infinite bus.

The available fault current at the point of connection [is [     ]] [must be assumed to be an infinite bus.]
