3 Identification of safety good practice in the construction and deconstruction of temporary demountable structures Annex A Suggested model for the safe management of temporary structures ES/FE/11/01/A Paul McCann BEngEngineering Safety Unit iii ACKNOWLEDGEMENTS HSL would like to thank all of the individuals and companies that have provided their advice and support in the compilation of this report.

4 HSL would like to extend particular thanks to those who made us welcome on their sites, often during periods of high activity and to those who facilitated those visits by making initial contacts. iv FOREWORD Each year, the UK holds a number of large events including sports, musical and corporate events. These events require extensive provision of temporary demountable structures (TDS) such as staging, seating, temporary buildings, video screens, camera platforms, etc.

5 In 2012, London will host the Olympic and Paralympic Games. The requirement for temporary demountable structures will be beyond anything undertaken in the UK for previous events and is likely to extend beyond the venues to include cultural and other events. This will put pressure on the associated supply chain in terms of capacity and experience. The provision of temporary demountable structures is influenced by factors that may have less significance in other industries such as speed of erection and deconstruction, limited use, adaptability of design, transportability and use by public.

6 management structures in the events industry are often less formalised than in other comparable industries. There have been failures of these types of structures, in the UK and beyond, including a recent incident in France, in which two died when a temporary stage roof collapsed during erection. HSL have undertaken a review of current management practices in the events industry, which is published in tandem with this work (HSL report ES/FE/11/01). This review identified potential weaknesses in some areas of the event management . This Suggested model seeks to clarify the good practice standards required for the safe design and construction management of temporary demountable structures.

7 The model includes recommendations for designers, clients, event managers and those workers involved in erection/deconstruction. v CONTENTS 1 1 2 DEFINITION OF 2 3 MANAGING THE 4 Selecting the 4 management Hierarchy .. 4 Time and 5 The Event Site or 5 4 DEVELOPING THE CONCEPT OF THE STRUCTURE .. 6 Determining the Design Concept .. 6 Time and 6 Managing the Location.

10 These can take place at a range of locations from city centres to remote green field sites. Sports stadia and arenas are commonly used as venues for events other than sports. Event organisers are frequently required to provide infrastructure as well as extensive provision of temporary demountable structures (TDS) including staging, seating, temporary buildings, video screens and camera platforms. The providers of temporary demountable structures are influenced by factors which may be far less significant to other industries, such as ease of erection and deconstruction, limited use, adaptability of design, transportability and use by public.
