Generally defined as large span aluminium frame or tensioned pole tents that are in excess of 25m wide. A giant structure is considered a specialist structure.

These can be 30m, 40, or 50m span frame tents usually needing the aid of telescopic plant or cranes to erect and dismantle. Giant pole tents can usually be erected manually, thus differentiating them from big tops that require plant.

Very few hirers are competent to deliver them safely.

What structural challenge becomes increasingly critical in wide-span temporary structures?

Controlling deflection (bending or sag) under loads, since bending movements grow rapidly with span.

How does the scale of anchoring and ground support change for giant structures compared to smaller tents?

Anchoring and foundations must resist much larger loads (uplift, lateral wind, shear) proportional to roof area.

What logistical challenges arise when moving or installing very large-span structures?

Transporting long frame elements, cranes, coordination of erection sequencing, and higher cost in labour and rigging.
