About this file
This is a site utility plan drawing for Building 631 demolition at Malmstrom Air Force Base in Great Falls, Montana, under contract NZAS 23-0030. The drawing details the utility disconnection and removal requirements for the demolition project.
The plan specifies key tasks including: terminating natural gas service and removing above-ground gas equipment; removing and capping water service lines while repurposing some for new irrigation; removing sanitary sewer services; pulling and storing fiber cable; demolishing HTHW lines to the valve station; coordinating with the 341 CES Electrical Shop for transformer removal; removing storm sewer laterals; removing the chiller and utility trench; and removing headbolt heaters while protecting certain infrastructure like light posts and a transformer. General notes require contractor notification of utility companies, obtaining work clearance permits, asbestos testing prior to demolition, and installation of a new irrigation system with backflow preventer and relocated control panel for the newly seeded area after demolition.
