ESTA ES1.19 PDF

Scope, purpose and application

The scope of this standard covers any temporary structure used for special events ("temporary special event structures"), where such structures are used for presentation, performance, structural support of entertainment technology equipment, audience seating or viewing in conjunction with the event, and regardless if the event is indoor or outdoor.

The scope of this standard covers any such structure not otherwise addressed by existing standards, codes or legislation, and to the extent that such other standards, codes or legislation do not already address conditional use of those temporary structures within existing structures.

Purpose

The purpose of this document is to identify design, fabrication, operation and use, inspection and maintenance requirements for the structures included in its scope. This document provides general guidelines for structures. It is not meant to replace the advice of a professional engineer or the requirements dictated by the authorities having jurisdiction for the event site.

Intent

This document is intended for use by both users and enforcement officials in order to help establish and maintain minimum standards for care and public safety during special events. It is not intended for use as a design manual.

Application

This document is one part of a larger collection of standards relating to special event safety. The requirements of the complete collection shall be considered in relation to the application of this standard, where necessary to coordinate and correlate all related requirements into the scope of a special event.

This document provides guidance and general structural design requirements, but should not be construed as a design manual for the complete structural requirements for any given structure. The application of this standard is relevant to three primary phases of event production*: design, installation/dismantle, and operational use. Applicability of this standard may vary based upon the risks associated with each phase.
