About this file
This document is a technical drawing specification for pipe penetration through a fire-rated partition at Mansfield Lahm Air National Guard Base, Ohio, as part of Contract FA877006 for Repair B403 for Cyber. The drawing, prepared by Jacobs Government Services (2600 Michelson Drive, Suite 500, Irvine, California 92612), depicts the installation details for a PTB (pipe through boundary) secured to non-secured boundary pipe penetration at a 3-inch scale (3" = 1'-0").
The specification details the materials and installation requirements for the pipe penetration assembly. Key components include a metal conduit/pipe with RF (radiofrequency) shielding mechanically bonded to the flange using conductive tape, RF shielding around the metallic pipe with sealed seams, a pipe clamp to secure the shielding, a firestop pipe collar installed per manufacturer's instructions, and a PVC to EMT adaptor or dielectric coupler extending minimum 6" or 7 times the pipe diameter. The assembly requires insulation tightly packed in void space on both sides of the partition, fire-rated/acoustic sealant applied to all sides of the pipe penetration, and wire wheel cleaning of the metal surface for proper shielding contact. The document includes a note that the above specification is intended as an example only and that the contractor ultimately determines means and methods of installation while taking ownership of the work. The drawing sheet reference is RFI 03, Q.7., with project number PBXP222050.
