2.07 Raised Platforms – A Client’s Guide

All scaffold, raised floors, grids or similar platforms should comply with BS 5973 ? 1993 ?Code of Practice for Working Scaffold Structures in Steel and Special Scaffold Structures in Steel?. The Scaffold Contractor should supply drawings and calculations in writing prior to installation and a certificate of conformity upon completion.

When a marquee is being erected on a scaffold/raised floor, or similar platform it is for the Marquee Contractor to supply the Scaffold/Platform Contractor with a drawn plan showing points of load and weights at those points. Additionally the Marquee Contractor should show additional weights from anchorage and method of anchorage (e.g. dead weight or ratchet straps attached to additional foot plates outside of the platform).

It should also show any additional cross bracing that may well be required due to the additional height of the overall structure when completed. It should also show the height of the eaves and ridge of the proposed marquee.

The Event Organiser will have the responsibility of selecting a suitable (or unsuitable) location for such a structure. For example slope, softness of ground. However, these are possibly the reasons you are looking for this type of raised platform and you should make your Scaffolding/Raised Platform Contractor aware of the particular details of the location. The Event Organiser should also inform them of the maximum occupancy levels.

Platforms, stages and ramps that are accessible to the general public and are over 30 cm high should have hand rails fitted of at least 90 cm high of the platform and should have a mid way rail fitted.

Ramps that are accessible to the general public shall be of a non-slip finish and should not exceed a gradient of 1 in 12.

No storage of equipment or rubbish is permitted under stage or platforms.
