Sole Source Notice of Intent - Window Fabrication for ERDC GSL

The U.S. Army Corps of Engineers Research and Development Center (ERDC), Geotechnical and Structures Laboratory (GSL) intends to issue a Firm Fixed Price (FFP) sole source award to Physical Security, LLC (CAGE:

4MAJ3 / UEI: N828XLEASQN9) for four (4) type W-1 full size historic replication windows manufactured exclusively by Physical Security, LLC. The Structural Mechanics Branch (SMB) of the Geotechnical and Structures Laboratory (GSL) of the US Army Engineer Research and Development Center (ERDC) is conducting testing for the Pentagon Engineering and Architecture Division and requires type W-1 full-sized windows representative of those fielded in DoW maintained structures.

The original windows installed at the Pentagon were designed, fabricated, and installed by Physical Security, LLC. The manufacturing process, developed exclusively by Physical Security, LLC, is critical to the performance of the window and test results. Therefore, while other vendors may be able to manufacture windows with similar materials and properties, their process and materials may differ slightly.

In addition, the quality control may not be the same as that of Physical Security, LLC, causing skewed and incorrect research results resulting in mission failure by the ERDC and a potential loss of life for DOW employees involved in any future attacks on the Pentagon.

To meet the ERDC GSL’s requirement, it is essential that the testing involve accurately replicated historic window types currently installed at the Pentagon that can only be provided by Physical Security, LLC. As a result, Physical Security, LLC is the only known vendor who can provide the four (4) type W-1 full size historic replication windows. The award will be issued in accordance with FAR 13.500.

The applicable North American Industrial Classification System Code (NAICS) code is 332321, Metal Window and Door Manufacturing, with a size standard of 750 employees.
