Before the
Guests Arrive.

The build window

The build window is the period between the venue handing over an empty space and the doors opening. It is usually shorter than it should be, because venue hire for build days is a cost nobody wants and because the show date never moves.

Three things make a window workable. A sequence that respects physical dependencies. A crew sized for the sequence rather than for the budget. And a technical rehearsal protected at the end of it, not squeezed into whatever is left. If any one of those is missing, the window is not short — it is misplanned, and the difference matters because only one of those is fixable with money.

This guide covers that window. For the project lifecycle around it — listen, plan, prepare, execute, review — see the event execution timeline.

Load-in sequencing

Sequencing is not only vertical. It is also a traffic problem: the dock, the lift and the corridor are shared, and several contractors are working to the same clock. A load-in schedule should therefore be written by vehicle and by hour, not by day.

• Vehicle-by-vehicle call times, so the truck carrying the structure does not arrive behind the one carrying the furniture.
• Dock and lift slots booked with the venue and with any other contractor sharing them.
• A marshalling position for vehicles waiting, off the access route.
• Crate storage identified before anything is unloaded, because crates occupy more floor than people expect and have to come back out.
• A named person controlling the dock, with the authority to hold a vehicle.
• Contingency in the first day, not the last. Slack at the front absorbs a late delivery; slack at the back is already spent.

Logistics and support is where this sequencing is planned and controlled.

Power and rigging go first

These two determine what is possible, and both are frequently discovered to be inadequate on the first morning rather than during design.

• Power demand calculated in kilowatts against the real load, not the equipment list's headline figure, with the venue's available capacity confirmed in writing.
• Distribution planned on the drawing: where the boards sit, what runs from each, and how cable gets across routes people walk.
• Standby decided. Generator, UPS on control positions, or accepted risk — stated, not assumed.
• Rigging points confirmed against the venue's load limits before anything is ordered, with a ground-support alternative designed in case points are refused.
• Point loads documented and signed off, with the paperwork on site.
• Overhead work completed and cleared before the floor below is built, because coming back for it means dismantling what is underneath.

AVL systems covers the technical specification these two enable.

Install, then finish, then dress

The second half of a build is where quality is either protected or quietly lost. Three habits protect it.

Finish before dressing. Paint, edges, joins and cable management are invisible once furniture is in place — and they are exactly what reads as cheap in a photograph. A build that is dressed before it is finished never gets finished.

Proof every graphic with fresh eyes. Someone who has not read the artwork before should read every sign, screen and panel. Names, titles, dates and both language versions. This single step catches the most visible class of error at the lowest cost, and it has to happen while a reprint is still possible.

Protect what is finished. Covers, barriers and a rule about who walks where. A finished stage used as a walkway during the last day of install is a stage that needs touching up at midnight.

Production and fabrication covers the build and finish standards this applies to.

Technical rehearsal

Rehearsal is the only part of the build that produces no visible output, which is why it is the first thing a late schedule takes. It is also the cheapest risk reduction available, by a wide margin.

• Every cue run, in order, at the real pace. A cue that has been described has not been tested.
• Every piece of content opened on the machine it will run from, at full screen, in the room.
• Every microphone tested in position, with the doors in the state they will be in and the room's air handling running.
• The opening sequence run twice. It is the only moment with no recovery time behind it.
• Failures drilled: switch to the backup machine, lose the main screen, lose a microphone mid-sentence, lose house power.
• Comms tested with everyone on channel, including the people who will be furthest away.
• Run of show reissued afterwards, version-dated, carrying the changes rehearsal produced.

The documents that run the day

By the final build day the event should exist on paper in four documents, printed and carried.

• Run of show. Times, cues, owners, version and date. The single source of truth for what happens next.
• Contact sheet. One page, mobile numbers, every supplier and lead, no titles without names.
• Floor plans. Final positions, including the ones that changed during build, which is most of them.
• Staffing roster by shift, with positions and break times.

Printed, because the day you need them is the day several hundred phones saturate the venue's network. And version-dated, because the most expensive error on a show day is two people working from different versions of the same plan.

The final walkthrough

Done by the person who will make decisions during the show, not by the person who designed it. The designer sees what was intended; the operator sees what is there.

• Walk the guest journey from the car park or the drop-off, through registration, into the room, to a seat — at a guest's pace, not a crew member's.
• Sit in the worst seat and look at the stage and the screen.
• Walk the back of house: crew routes, green room, storage, catering access, waste.
• Check every threshold a steward will hold, and confirm they know what comes through it.
• Look up. Rigging, cable, gaffer tape, anything that reads badly in a photograph taken from the floor.
• Look down. Cable crossings, trip hazards, tape lifting, floor marks.
• Confirm emergency routes are clear and that the crew knows the venue's procedure, not only its own.
• Note everything and close it before doors, with one person holding the list.

What the crew does during the show

To an audience, nothing visible. That is the point. Operationally the show is four simultaneous jobs.

Calling. One person on comms reading the run of show, holding, extending and cutting. Everyone else executes rather than decides, which is what keeps a room coherent when the programme slips.

Operating. Audio, lighting, video and show control running cues; stage management moving people; registration handling late arrivals.

Watching. Someone whose only job is to notice: a door propped open, a queue forming, a microphone not switched on, a guest who needs help. Most recoveries start as an observation, not an alarm.

Preparing what is next. The next speaker found, the next cue checked, the next room reset. A show that is only ever handling the present moment is already late.

Crowd and site operations and event management are where the live command structure sits.

Dismantle and site recovery

Dismantle happens tired, at night, against a venue deadline, and it is where damage and loss occur. Plan it with the same seriousness as load-in.

• A dismantle sequence, which is not simply load-in reversed — technical and hired equipment leaves first, because it is the most valuable and the most likely to be charged for if late.
• A site-recovery standard agreed in writing before build, including who removes carpet, waste and fixings, and the condition the venue expects.
• Fresh crew where possible, or a rest break before dismantle starts. Damage correlates with fatigue.
• Hired equipment counted against the delivery note as it goes out, not back at the warehouse.
• A documented handover, photographed, so a later claim about the condition of a space has an answer.
• Lost-property and left-items process for guest belongings.
