Repair Roof Collapse Building 52, Bay 2 at DLA Distribution Susquehanna PA

On the evening of June 24, 2018, a section of roof (approximately 20' x 40') collapsed on Building 52, Bay 2. The Installation experienced a significant rain event the evening of June 24, 2018 and an excessive amount of water built-up on the roof as a result of multiple clogged roof drains not allowing the roof to properly drain. A deteriorated beam broke from the excessive rain/water build-up on the roof and the section of roof collapsed. The roof must be repaired and all remaining existing beams inspected immediately before mission can resume. This work is deemed an Emergency Repair for the following reasons:
The roof damage has resulted in the decision to close the entire building to DLA Distribution Operations. The area had to be tested for asbestos before anyone could enter. Only after Installation Operations has the entire building's structural systems inspected and deemed safe for use by a Structural Engineer may Mission Operations resume. The damages adversely affect DLA Susquehanna Warfighter Mission First and must be repaired immediately to secure the building and make it safe, so the building can be reopened as soon as possible.
Building damages extend beyond those for the roof structure. Additional building systems damaged by the collapse and critical to resumption of Mission operations include the Fire Suppression, Steam Heating, Interior Lighting, Telecommunications, and Interior Electrical Distribution.
