Construction documents: Construction documents shall be prepared by a registered design professional in accordance with the International Building Code by a registered design professional and ANSI E1.21 where applicable. Construction documents shall include:

A summary sheet showing the building code used, design criteria, loads and support reactions. Detailed construction and installation drawings. Design calculations. Operating limits of the structure explicitly outlined by the registered design professional including environmental conditions and physical forces. Effects of additive elements such as video walls, supported scenery, audio equipment vertical and horizontal coverings. Means for adequate stability including specific requirements for guying and cross-bracing, ground anchors or ballast for different ground conditions.

Designation of responsible party: The owner of the temporary stage canopy special event structure shall designate in writing a person to have responsibility for the temporary stage canopy special event structure on the site. The designated person shall have sufficient knowledge of the construction documents, manufacturer’s recommendations and operations plan to make judgments regarding the structure’s safety and to coordinate with the fire code official.

Operations plan: The operations plan shall reflect manufacturer’s operational guidelines, procedures for environmental monitoring and actions to be taken under specified conditions consistent with the construction documents.

3105.6 Inspections. Inspections shall comply with Section 106 and Sections 3105.6.1 and 3105.6.2.

3105.6.1 Independent inspector. The owner of a temporary stage canopy special event structure shall employ a qualified, independent approved agency or individual to inspect the installation of a temporary stage canopy special event structure.

3105.6.2 Inspection report. The inspecting agency or individual shall furnish an inspection report to the fire code official. The inspection report shall indicate that the temporary stage canopy special event structure was inspected and was or was not installed in accordance with the approved construction documents. Discrepancies shall be brought to the immediate attention of the installer for correction. Where any discrepancy is not corrected, it shall be brought to the attention of the fire code official and the designated responsible party.

3105.7 Means of egress. The means of egress for temporary stage canopies special event structures shall comply with Chapter 10.

3105.8 Location. Temporary stage canopies special event structures shall be located a distance from property lines and buildings to accommodate distances indicated in the construction drawings for guy wires, cross-bracing, ground anchors or ballast. Location shall not interfere with egress from a building or encroach on fire apparatus access roads.

Add new text as follows:

3105.9 Portable fire extinguishers Portable fire extinguishers shall be provided as required by Section 906.

Reference standards type: This is an update to reference standard(s) already in the ICC Code Books

Add new standard(s) as follows:

ANSI E1.21-2013 Entertainment Technology – Temporary Structures Used for Technical Production of Outdoor Entertainment Events

Reason: This is the second proposal in a package of four Chapter 31 proposals submitted by the F-CAC to revise, update and reorganize Chapter 31.

These four proposals are intended to improve the minimum level of safety relating to all types of temporary structures and outdoor public gatherings; improve the correlation of requirements in the IBC and IFC for temporary structures and better correlate the applicability of IBC structural requirements for all types of temporary tents, membrane structures and other outdoor structures.

These proposals have been prepared by a F-CAC Work Group comprised of code officials, industry representatives and other stakeholders.  The Work Group analyzed several fatal events related to outdoor public gatherings and structural failures in the development of these new code requirements to improve the authority of code officials to ensure public safety and create a level playing field for the owners of tents, outdoor structures and the promoters of outdoor gatherings by providing a reasonable set of code requirements for these structures and events.

  1. The Indiana State Fair stage collapse – August 13, 2011
  2. Wood Dale Prairie Fest (Chicago area) – August 2, 2015
  3. Circus tent collapse Lancaster Fairgrounds (New Hampshire) – August 3, 2015

Specifically, this proposal:

  1. Changes the title and scope of Section 3105 and replaces the term “temporary stage canopy” with “special event structure”. This change in correlation with the proposed new definition for temporary special event structures is intended to expand the scope of Chapter 31 to include all structures related to temporary structures, typically used in outdoor situations.
  2. Adds a definition for special event structure to the IFC.
  3. Adds the requirement for a construction permit for all temporary special event structures

The effect of this change is to expand the scope of this section beyond strictly “temporary stage canopies” which currently excludes many types of temporary structures that should be regulated by this Chapter of the IFC.  The change will ensure that structures covered by ANSI E1.21 will be structurally engineered.  This change will ensure that all temporary structures not regulated by the IBC will be regulated by this chapter of the IFC. The addition of the construction permit requirement will ensure that all temporary special event structures will be subject to a plan review and site inspection to ensure structural stability and reliability for public safety.  The permit will also cover the safe dismantling of these structures to ensure public and worker safety.

A requirement to provide an approved fire extinguisher was to ensure a minimum level of fire safety at or near all special event structures.  This is consistent with the existing requirement in this chapter for providing fire extinguishers in tents and membrane structures.  A portable fire extinguisher at each structure would decrease travel distance to obtain a portable fire extinguisher and would ensure availability to extinguish a fire in its incipient stage.

With these package of proposals submitted by the F-CAC, any temporary structure not regulated by the IBC would be covered by Chapter 31 of the IFC.

A new definition was added to describe “temporary special event structures” to be regulated by this section,.  This requirement will ensure that all outdoor structures are regulated by the IFC with the requirements for structural engineering or analysis that is necessary to prevent collapse of these structures.

This proposal is submitted by the ICC Fire Code Action Committee (FCAC). The FCAC was established by the ICC Board of Directors to pursue opportunities to improve and enhance assigned International Codes with regard to fire safety and  hazardous materials in new and existing buildings and facilities and the protection of life and property in wildland urban interface areas.   In 2014 and 2015 the Fire-CAC has held 5 open meetings.  In addition, there were numerous conference calls, Regional Work Group and Task Group meetings for the current code development cycle, which included members of the committees as well as any interested parties, to discuss and debate the proposed changes. Related documentation and reports are posted on the FCAC website at: FCAC

Cost Impact: Will not increase the cost of construction

This proposal only addresses temporary structures and therefore does not increase the cost of building construction.

Analysis: An update to ANSI E1.21-2013 Entertainment Technology – Temporary Structures Used for Technical Production of Outdoor Entertainment Events, is part of the existing standards update proposal, ADM94-16.
