PERFORMANCE TECHNICAL SPECIFICATION

SECTION D50

ELECTRICAL
09/22


NOTE:  This section is intended to be used as a guide and contains requirements that are common to many different types of facilities; however, not all requirements and equipment items will be applicable to all projects.  In addition, there may be special requirements for a particular project that are not addressed at all.  The RFP preparer may have to incorporate additional information to address these special requirements in this PTS and corresponding Part 3 ESR.  If the RFP preparer chooses to delete building elements that are not required for the project, do not change the remaining Uniformat paragraph designations (example - A102001). Uniformat designations are unique to the products they are assigned to. However, the subparagraph numerical extensions (example - 1.2 or a,b,c) of the Uniformat designations may change if subparagraphs are deleted.

This guide specification is formatted utilizing Uniformat II, an industry recognized standard, ASTM E 1557.  When the RFP preparer chooses to add a paragraph that does not apply to an existing building element already included in the specification, refer to the Uniformat/WBS located on the NAVFAC Design-Build Website for a listing of Uniformat II designations and definitions.

NOTE:  The RFP preparer may view or hide the criteria notes in this PTS section by modifying the WORD preferences for "Hidden text".  To view the criteria notes, choose "File" then "Option".  Click "Display" then check the "Hidden text" box under "Always show these formatting marks on the screen".  In the same section, check the box for "Print hidden text" under "Printing options" to print the criteria notes.


NOTE:  The Table of Contents is intended for navigation purposes only for the RFP writer and should not show up in the printed document.
