Temporary structures like event tents, marquees, and pop-up halls are essential for festivals, exhibitions, and commercial storage. However, because they lack traditional foundations, they face unique structural risks from wind, snow, and soil instability.

When installing large tents, marquees, or mobile temporary structures, ensuring structural integrity and safety is paramount. The is the definitive European norm governing the design, calculation, manufacture, installation, and maintenance of temporary structures, particularly those exceeding

Safe installation begins long before the first stake is driven into the ground. Installers must execute a rigorous site assessment. Ground Conditions and Soil Bearing Capacity

Create an on-site checklist from the standard’s requirements covering:

Assemble the portal frames (legs, rafters, and ridge purlins) flat on the ground using protective ground sheets to avoid scratching the aluminum profiles.

On concrete or asphalt where ground penetration is impossible, concrete blocks or water weights are mandatory. The total weight must strictly adhere to the manufacturer’s structural calculations for wind uplift.

The (Clause 14 of the standard) serves as the primary technical record and should be available on-site for inspectors. It typically contains: Identification of the tent. Reports of initial and periodic examinations. Records of repairs or modifications after accidents. Certificates of flame retardancy for the covers.

Following a logical, systematic assembly sequence reduces the risk of structural damage and workplace injury during setup. Step 1: Layout and Baseplate Positioning Measure and mark the exact footprint of the structure.

: Documentation of emergency escape routes, electrical fittings, and heating systems. 2. Installation Examination and Testing

Inspect all side walls, close all open curtains, and check anchor tension.

Mechanical or chemical expansion anchors rated for the specific tensile load. Asphalt, city squares

The site should be flat and level. Sloped terrain introduces uneven forces on the framework, demanding engineering approval or adjustable flooring systems to normalize the load.

If used at night, exit routes must feature illuminated emergency signage backed up by an independent power source (battery or generator). 6. Inspection, Maintenance, and Use

The stability of the marquee depends on proper anchoring to the ground. The installation manual must specify: The type of ground.

Structure must be entirely empty; secure the perimeter to protect the public from potential flying debris. Summary Checklist for Site Managers
