PERFORMANCE TECHNICAL SPECIFICATION

SECTION G30

SITE CIVIL/MECHANICAL UTILITIES
05/14


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 in the document pull down menu for "Hidden text". To view the criteria notes choose "Tools, Options, and View," then check the "Hidden text" box, to print the criteria notes choose "Tools, Options, and Print," then check the "Hidden text" box.
