Start with the fleet inventory and record the length, width, height and turning needs of each vehicle. Include mirrors, raised equipment, mounted tools or other projections that affect clearance. Plan parking positions with enough room to enter and leave without moving neighboring vehicles. A dense arrangement can reduce the number of bays on paper but slow every dispatch if drivers must reposition equipment first. Review the layout against the busiest shift, not just average occupancy. Vehicle queues, late returns and equipment temporarily held for inspection can all reduce usable space. A planned overflow or staging position gives dispatchers somewhere to place a vehicle without taking another unit out of service.
Decide whether vehicles reverse into spaces, drive through, or use a separate staging apron. If several vehicle types share a garage, group them according to size and how frequently they are dispatched. Keep walkways, personnel doors and access to equipment storage free from parked vehicles. Airport traffic rules and airside routes must be coordinated with the operator. Leave a buffer position for vehicles that return with a fault or require cleaning before re-entry into service; otherwise, the garage can become congested when a shift change creates the most movement.
