Temporary Demountable Structures, Guidance on Procurement, Design and Use.
Third Edition published in 2007 by the IStructE.
"This Guide is concerned with the structural safety and adequacy of demountable structures used for temporary purposes and also with the overall planning and management of events".
Technical Standards for Places of Entertainment.
Published in April 2001 and reprinted with revisions in January 2002 by The District Surveyors Association and The Association of British Theatre Technicians.
"The District Surveyors Association (DSA) and the ABTT with valuable assistance from the Fire Service have produced these new Technical Standards for Places of Entertainment. They are offered for the use of both licensing authorities and licensees nation-wide. They form a guide to good practice for anyone concerned with the building and maintenance of places of entertainment."
Whilst both of these publications refer to themselves as Guides, their adoption by the industry has seen them set the standards that all reputable companies work to.
