Murray Contractors was hired through the JOC contract to perform the initial phase of Central Building code upgrades.  Work included installation of risers/backflow for the addition of fire sprinklers to the entire building, isolating domestic water services from old gravity feed systems to pump systems with new VFD systems, removal of old gravity feed systems. Coordination and scheduling was key because multiple shutdowns were required.  The domestic water for the building had to be shut down 100% to make the switch so 3 crews were prepared to run the 24 hour shutdown switch over and it was completed 12 hours ahead of schedule. Shutdown of the main hospital loading dock was also required for the tank removal, which took weeks of planning and coordinating with every UAMS department to ensure all deliveries were made before or immediately after the 18 hour shutdown.  Murray Contractors understands the requirements and needs of extremely difficult projects and has the team to handle them.
