Singapore Grand Prix: How the supercars arrive at the tarmac - SilverKris

"This city-state night-time street circuit hosts the Grand Prix and requires months of meticulous planning: teams begin monitoring ground conditions and potential roadworks four months out to protect last-minute car parts, and cargo manifests—often hundreds of tonnes and millions of dollars in value—are timed to arrive precisely. A multi-agency arrangement simplifies temporary import permits and gives priority customs clearance for race cars and equipment, while the size and layout of the paddock determine how quickly garages and hospitality units can be broken down and packed (typically a six- to eight-hour operation when space and access allow)." - SilverKris
