- Stability at all stages of construction and dismantling
- Identifying the point at which the structure can support itself
- Identifying the permanent elements that ensure stability
- The sequence of construction and the sequence for the removal of any temporary parts
- Calculations indicating the relevant forces and load capability of the structure
- The floor loading capacity of the venue
CONSTRUCTION AND DISMANTLING
- Drawings must clearly identify the sequence of construction, e.g. construction of frame; insertion of legs; fixing of bracing
- A clear plan for dismantling the stand must be identified
- The time available for construction and dismantling of the stand must be taken into consideration
- A safe system of work must be identified within the methods for construction and dismantling, i.e. work equipment; temporary handrails; fall-arrest system
ASSESSMENT OF LOADS
- A realistic assessment of the loads and forces at each stage should be made in consideration of the erection sequence.
- The design should consider the safest means of connecting components and, where appropriate, indicate the necessary provision of access equipment and the safe system of work
- Connections shall be simple and effective to reduce the time spent working at height
- The design should take account of the safe handling, lifting, storage, stacking and transportation of the components relevant to their size, shape and weight
The preparation of a construction Method Statement is a vital step in the planning of a safe system of work. The Method Statement must detail the steps taken to build and dismantle the stand i.e. the sequence of construction and the sequence of the removal/breakdown of the stand, identifying the critical controls and procedures to avoid accidents. A safe system of work must be identified within the methods for construction and dismantling of the stand.
The Method Statement for a double decker stand should include:
- Construction sequences i.e. the build and the dismantling of the stand, noting the starting point. Clear identification of the sequence of construction e.g. construction of frame; insertion of legs; fixing of bracing. The time available for construction and dismantling of the stand must be taken into consideration.
- Methods to ensure stability, including the use of temporary components and systems
- The detailed construction scheme that identifies the lifting, alignment and connection requirements of the stand.
- The preferred system to prevent falls from height, the safe means of access and any special platforms or equipment used e.g. temporary handrails, fall-arrest system etc.
- The provision of suitable personal safety equipment and construction equipment with which to construct the structure safely.
IMPORTANT: Work on site will be checked against this information and will be stopped where it does not comply; dangerous work practices will not be tolerated and persons may be removed from the venue if necessary. As much of the construction as is possible should be completed at floor level, then lifted into position. This should include decking and the erection of handrails to ensure a safe place of work on the upper level once lifted, to avoid the need to provide additional safety measures such as temporary edge protection and fall restraint or arrest systems. Please note that 'live' or 'open edge' working at height is strictly prohibited.
Please familiarise yourself with the relevant Dutch Building Standards for Double Decker Stands such as strength, stability and point loads including railings and stairs. It is highly recommended that exhibitors and/or their contractors contact the RAI Amsterdam structural engineer for further details before designing their Double Decker stand.
