NAVFAC Design-Build Model Request for Proposal - Armory

D50 ELECTRICAL


SYSTEMS REQUIREMENTS
ELECTRICAL TEMPLATE 06/23

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.

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 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.
