Double Decker Construction Guidelines

The following guidance serves to help identify the main elements of safe construction of a Double Decker stand. The following considerations must be addressed by the designer of a double decker stand.


  • 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 


  • 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 


  • 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. If you have any questions, please email licenses@rai.nl.


  1. Method Statement and Risk Assessment of the stand build must be provided and must be followed. All persons involved with the work must be competent to undertake the work and have read and understand the method statement and risk assessments and erection sequence(s). 
  2. Competent supervision is required, and supervisors must be trained and understand the work they are to supervise. They must be able to read and understand the drawings and method statements and ensure that they are appropriate for the structure and its location. Where the methods are changed, the designer shall authorise the change, in writing, prior to the documentation being changed and these must be re-submitted to the Organiser and Amsterdam RAI structural engineer for approval. 
  3. Weights of components should be clearly marked and where necessary, lifting points indicated. Components should be stacked and delivered so that they can be removed in the desired order. 
  4. Deliveries must consider the Floor Loading in the area of erection or unloading. 
  5. Hard hats and steel toe-capped boots are necessary personal protection equipment (PPE) for working with steel structures. It may be necessary to cordon off the area of the build when overhead working is taking place. 
  6. Welding and cutting (fabricating) is not allowed within the RAI Amsterdam without the prior written consent of the venue. Please refer to Fire Regulations for Hot Works and Naked Flames
  7. Plant and equipment must only be operated by a competent person and copies of their licences or certificates must be available for inspection at any time. 
  8. Lifting the main deck using several forklift trucks is acceptable provided a Method Statement has been accurately filled out and approved by Abraxys. 


Please see Double Decker Stands for important information regarding the submission of build approval documentation and obtaining a build permit. 


Hard hats and safety shoes are compulsory for anyone in the halls during the build-up period of Thursday 1 to Wednesday 7 September. Depending on conditions within halls, exhibitors may be required to wear PPE on Thursday 8 September. PPE can be ordered through the RAI Webshop or purchased onsite at the RAI Hospitality Crew Centre (subject to availability). For more information, please see Health & Safety Rules for Working Onsite.


  • Seal off the area
  • All necessary PPE (Personal Protection Equipment) to be worn
  • Construct upper deck first at ground level - install as much flooring as possible before lifting
  • Install handrail or temporary handrail before lifting
  • Lift upper deck with suitable and checked equipment or official lifting contractor
  • No live edge work at all
  • Assemble ladders and towers to undertake work on the upper deck
  • Follow plans/Risk Assessments and Method Statements precisely - any changes must be pre-approved
  • Await structural inspection before cladding or flooring steelwork
  • Maintain a clear and tidy site at all times
