Multi -Roof Replacement Project

Description

There are several existing roofs (C50 ESAT Building/C52 PLT Power Building/C60 C Site Pump House/D45 Rad Waste Handling Facility) which are past their useful life requiring costly maintenance to upkeep. Severe water infiltration occurs regularly at failing joints, punctures, and flashing. Portions of existing metal coping have pulled away during storm events causing large sections of membrane to separate from the substrate. A catastrophic failure to one of these roofs would negatively impact the ability to conduct the top priority experimental operations in the Laboratory. 1.2. SCOPE 1.2.1.
