EXHIBIT_Z_-_JMMU_SACON_Trench_System_Repairs.pdf

This document is Exhibit Z of a federal contract solicitation presenting photographic and technical specifications for repairs to the JMMU (Joint Multinational Maneuver Unit) Trench System facilities, consisting of a Machine Gun Bunker and Command Bunker with associated defensive infrastructure.

The repair scope encompasses structural restoration and defensive hardening of two primary bunker structures. For both bunkers, work includes replacing damaged 2x8 wooden beams and reinstalling lag bolts with washers according to existing layout specifications. The Machine Gun Bunker repairs additionally require extending superficial Sandbag, Concrete and Obstacle (SACON) protective walls to the trench perimeter and installing plywood panels between the wooden opening frame and SACON walls to prevent hand grenades from catching and bouncing back into the structure. The opening framing requires replacement of 2x4 wooden members consistent with original construction. The Command Bunker repair scope includes similar structural restoration with superficial SACON wall protection around the entire bunker perimeter. The document provides annotated photographs showing damage conditions from both external and internal perspectives, with detail views of the opening damage and construction specifications. All repairs are to follow existing structural layouts and material specifications without modification to original design parameters.
