A Festival Build-and-Teardown Schedule That Keeps Corridors Open

At 16:20 on the opening Saturday, a steward closed the north corridor because a pallet of snow bags was still sitting in it. The build had finished two hours earlier. Nobody had moved the pallet, because the crew that built the display had gone to the second site and the pallet was not on anybody’s list. The corridor stayed shut for forty minutes and the organiser spent them explaining to a fire officer why his evacuation route was full of polymer.

Most festival snow problems are not snow problems. They are movement problems: material arriving through a route that is about to fill with the public, or leaving through it after the doors have opened. The fix is a schedule written in hours, not days, with the corridor as the fixed constraint and everything else arranged around it.

The build window is smaller than the booking says

Organisers book you a day. What you actually get is the four hours between the fire inspection and the first delivery of stock to the neighbouring unit. Treat the booked day as the outer limit and plan to finish in 60 percent of it, because the last two hours are always eaten by somebody else’s delay.

Sequence the build by weight of traffic, not by aesthetics. Heavy materials move first, while the floor is clear and the doors are wide. Anything that needs water goes next, because water is the slowest thing on site and the least forgiving if the supply is shared. The light decorative work goes last, when you can stand back and see it. Crews that build the pretty part first spend the afternoon walking past their own display with a trolley.

The teardown is where the corridors close

Striking a snow build produces volume. A 40 square metre display at 6 cm is roughly 2.4 cubic metres of wet material, and wet material does not go back into the bags it came in. It goes into bins, and the bins have to travel the same corridor the public used, which is now full of people leaving.

Two things prevent the 16:20 problem. First, bag and stage the material inside the display footprint during the last hour of the event, so it is ready to move the moment the floor clears. Second, book a service lift or a rear door for a named half-hour window, in writing, with somebody’s phone number on it. Verbal arrangements with venue staff dissolve at exactly the moment you need them.

A schedule that survives contact with the day

• T minus 24 hours: material on site, stored off the corridor, photographed in place
• T minus 4 hours: heavy build complete, water supply released
• T minus 90 minutes: detail work, matting down, walkway signed off
• T minus 30 minutes: tools and empty bags removed from the public route, not just stacked to one side
• T plus 0: one crew member on standby with a broom and a bin, doing nothing else
• T plus 60 minutes: strike begins inside the footprint, material staged, not carried

The standby person is the item clients resist paying for and the one that saves the day. Their job is not to build anything. It is to catch the drift that gets kicked, the bag that splits, and the child who decides the snowbank is a slide. One person, four hours, and the display still looks like the photograph at nine in the evening.

What to write on the site plan

Mark three routes on the plan and give them names the whole crew uses: in, out, and public. Tape them on the wall of the crew room. When somebody asks where the empty bags go, the answer is a route, not a direction. It sounds bureaucratic until the first year you run a festival with four builds and one van, at which point it is the only thing keeping the day linear.

Give the venue a one-page movement plan at the same time as the risk assessment. It costs ten minutes to write, and it turns the corridor conversation from an argument into a check.

Schedules, movement plans and a strike checklist for multi-site events are in the artificial snow user guides, sized for a crew that has never worked this venue before.
