The machines around the machine.
Production plant gets attention. Lighting, pumps, power, amenities, traffic gear and service vehicles are what let it keep working.
Follow the dependency
List what stops when power, water management or access support fails. Those dependencies deserve their own availability and backup checks.
Place support deliberately
Cable runs, hose routes, refuelling points and amenities should not compete with haul paths or lifting zones.
Plan consumption
Fuel, water, consumables and waste need replenishment cycles. Define responsibility before the first long shift.
