A courthouse can't close for a re-roof. A library branch stays open to the public, a fire station has to roll apparatus at any hour, and a public-safety building runs three shifts a day. We sequence work on occupied government facilities so the building keeps functioning underneath us. That means staging tear-off in sections small enough to be dried-in the same day, never leaving an open deck exposed to an afternoon thunderstorm, and protecting interior spaces and equipment below from dust and debris. Crews and material loads are routed away from public entrances, drop-off lanes, and emergency-vehicle bays. Where a department is sensitive to noise or vibration - a courtroom in session, a 911 floor, a clinic - we schedule the loudest phases around it.
Coordination with the facilities staff runs through the whole job. We agree on roof access, lay-down areas, crane and lift placement, and security and badging requirements before mobilization, so a crew on a secured campus isn't an interruption to operations. On buildings with restricted or sensitive areas, we plan our access to respect them.
