Key takeaway
How we deliver stage & truss fabrication
Structure is the one department where getting it wrong is not an aesthetic problem. Every stage and truss build starts from a load case: the dead load of the structure itself, the live load of performers and crew, the suspended loads of lighting, audio and LED, and — outdoors — wind load on any banner, roof or solid surface. We specify from manufacturer load tables for the exact truss type and span, with chain hoists rated well above the working load and point loads calculated per leg. Decks are Layher or aluminium framed systems with a published uniform load rating, and a performance stage is typically designed for 500 kg per square metre of distributed live load.
Ground support and roof systems are where wind becomes the governing factor. A solid or banner-clad roof is a sail, and the force on it rises with the square of wind speed, so every roof design comes with a wind management plan: a speed at which banners are removed, a higher speed at which the roof is lowered or the show stops, and a ballast or ground-anchor scheme calculated for the site's surface. Ballast is not a number we guess — concrete blocks or water ballast are specified against the structure's overturning calculation, and soft ground needs load-spreading plates or a different anchoring approach entirely.
The rigging discipline on site is what turns a design into a safe build. Hoists are inspected, chains checked for wear, steels and shackles used within rated capacity with a safety factor appropriate to lifting over people. Every hang point is bonded, every hoist is controlled from a single position, and nothing moves while people are underneath. We run a pre-show structural check after the full rig is loaded and again before doors, because a structure that was correct when empty can reveal a problem once 2 tonnes of lighting and LED is on it. The build sequence, the bolt torque, the hoist inspection and the final sign-off are all documented.

Crew
Who turns up on show day
- Structural designer
Produces the load case and the calculations, specifies truss and hoist capacities and signs the point-load report.
- Crew chief
Owns the build sequence and the clock, and holds the authority to stop the build if anything departs from the drawing.
- Lead rigger
Inspects hoists and hardware, controls all lifting from a single position and signs off before anything goes to trim.
- Stage carpenter
Builds decks to level, fits stairs, handrails and edge protection, and closes every gap a heel or a cable could find.
- Competent person on site
Performs the structural checks after loading and before doors, and owns the wind management decisions on an outdoor roof.

Risk control
What goes wrong, and how we stop it
What can go wrong
How we prevent it
- What can go wrong
Departments add lighting, LED and audio beyond the load the grid was designed for.
How we prevent itA single suspended-load budget is published at T-4 weeks and every department's weight is booked against it; anything added later triggers a recalculation before it is hung.
- What can go wrong
A banner-clad roof becomes a sail and the structure approaches its overturning limit in a squall.
How we prevent itThe wind management plan sets a numeric speed at which banners come off and a higher one at which the roof is lowered, with an anemometer on site and a named person empowered to act.
- What can go wrong
Ballast is placed on soft or wet ground and begins to sink, taking the structure out of plumb.
How we prevent itGround bearing capacity is assessed before the build, load-spreading plates are specified for soft surfaces, and plumb is re-checked after the first night.
- What can go wrong
The venue quotes a rigging capacity that turns out to be an assumption rather than a calculation.
How we prevent itWe require written sign-off on point loads and, where it is not forthcoming, quote a ground support system that carries its own load to the floor.
- What can go wrong
Stage gaps and unprotected edges become an injury risk once performers and guests are moving fast.
How we prevent itDeck gaps are closed and taped, edge protection and handrails are fitted to code, and the carpenter walks the whole deck surface before anyone is allowed on it.
- What can go wrong
Lifting continues while other crew work underneath because the build is behind schedule.
How we prevent itAll lifting is controlled from a single position with the area cleared, and the crew chief has explicit authority to stop a build that is being rushed.
Honest comparison
Is this the right choice for your event?
- Ground support towers instead of flying from the venue structureOur verdict
Ground support costs more and eats floor space, but it carries its own load to the floor and removes any dependence on a venue capacity you cannot verify. Where the venue has documented, engineered rigging points, flying is cheaper and cleaner.
- Scaffold stage instead of a modular deck systemOur verdict
Scaffold is cheaper and infinitely adaptable, and for a long-run outdoor build on uneven ground it is often the sensible choice. Modular decks are faster, flatter, quieter underfoot and look finished without extra cladding.
- A roof system instead of a tent or shamiana over the stageOur verdict
A fabric structure is cheaper and keeps rain off people, but it will not carry lighting or audio load and its own wind behaviour is usually undocumented. If anything needs to hang above the stage, it needs an engineered roof.
- Lower stage height to save cost and build timeOur verdict
Often a good call indoors where the audience is close. On a deep standing audience, a 0.6 m stage means the back two thirds see nothing, and IMAG screens become the only reason they stay — which costs far more than the deck did.
