EXHIBIT_Z_-_JMMU_SACON_Trench_System_Repairs.pdf

This document is Exhibit Z containing technical repair specifications and photographic documentation for JMMU (Joint Multinational Readiness Center) Trench System bunker repairs, presented as a construction/repair scope exhibit.

The exhibit documents damage to two bunker types within the trench system—a Machine Gun Bunker and a Command Bunker—and specifies required repairs. For both bunker structures, the primary repair requirement is to replace 2x8 dimensional lumber on damaged sides and reinstall lag bolts with washers using the existing attachment layout. For the Machine Gun Bunker specifically, additional repairs include installing plywood between wood openings and superficial SACON (Semi-Automated Construction) walls to prevent hand grenades from catching and bouncing back, with replacement of 2x4 members at the opening to match original specifications. The Command Bunker repairs follow the same lag bolt replacement protocol. The exhibit also shows that superficial SACON protective walls are to be extended to the trench line, with the reinforced walls highlighted in magenta/purple overlay diagrams. Photographic evidence includes exterior and interior views of the Machine Gun Bunker opening damage, showing deteriorated wooden structural members with visible lag bolt holes marked with circles, internal cavity damage to wooden beams and supporting framing, and exposed concrete walls. The repairs address structural degradation consistent with combat damage or extended weathering exposure to existing military fortification infrastructure.
