Requirements for Outdoor Event Structures

Transcription

1 Requirements for Outdoor Event Structures The structure shall be a purpose built system used in accordance with its intended purpose. All aspects of the structure shall comply with ANSI E or an equivalent standard as identified by a qualified person. If a standard other than ANSI E is referenced, then a thorough justification must be provided. The event producer shall submit the required documentation including the event structure specific action plan to the artist team no later than seven (7) days prior to the commencement of the construction. Any changes, additions and modifications to the structure or the plan shall be completed and submitted no later than three (3) days prior to the commencement of the construction. Changes or modifications after this date will not be accepted. If local jurisdiction permits/approvals are required, the above timing requirements shall be submitted with reference to the permit submittal date rather than the start of construction. Compliance of the structure to ANSI E must be demonstrated by providing a Letter of Conformity/Compliance prior to the day of the event. This letter must include the following supporting documentation: 1. DRAWINGS: Assembly diagrams, plan and elevation views, identifying: a. Positions and connections for all structural elements including lifting devices (motors), lock-off devices, guy cable connections, guy cable anchorage/ballast requirements, etc. b. Areas and limits of allowable wind areas including: i. Stage covering ii. Side/back walls iii. Additional signage iv. Suspended audio, lighting, video and scenic equipment 2. CALCULATIONS: Allowable load documentation from licensed engineer indicating limits of the structure for: a. Allowable equipment loads for show equipment (live load) for audio, lighting, scenery, video, etc.; b. Environmental limits including seismic and wind loading; c. Ground conditions, capacities and foundation requirements; d. Lateral stability requirements including anchorage details i. Differences between ground anchorage and ballast requirements must be clearly identified; Page 1 of 6

2 e. Load assumptions and considerations; f. Operations Management Plan minimum requirements 3. EVENT SPECIFIC COMPLIANCE: Summary of the specific event loads (rigging plot, audio loads, etc.) and conditions that demonstrates the structure is sufficient for the intended purpose including: a. Suitability of the site: i. Access for equipment and erection of structure; ii. Ground conditions; iii. Underground interferences (sprinkler systems, utilities, etc.); iv. Condition of elevation changes affecting structure (changes in ground height); b. Overall site layout diagram showing: i. Location of structure ii. Access locations iii. Audience location(s) c. Rigging plot overlaid on structure indicating suitability; d. Copy of permit(s) from the local jurisdiction event is to be held if applicable; e. Inspection records of the structure and its components should be available upon request as needed; 4. OPERATIONS MANAGEMENT PLAN: Action plan indicating the various stages of operating conditions of the structure and the actions to be taken when those conditions are encountered. A sample of a risk assessment and Operations Management plan indicating possible stages of incidents requiring action is provided below. This sample represents the MINIMUM level of information required. a. WIND: i. Monitoring 1. A specified individual responsible for monitoring on site conditions and forecasted conditions must be identified prior to event; 2. Wind must be monitored at all times on site via anemometer or other appropriate device; Page 2 of 6

3 3. A reliable line of communication must be established with local weather resources to monitor impending conditions. This connection must be available at time of load in through the completion of the event; ii. Actions: Identify what actions will happen at the following measure wind speeds. These actions MUST consider the nature of the loads on the structure specific to this event. For example, if there is equipment on the structure that prevents it from being lowered to the ground, then lowering the structures to the ground is not an option to be considered in the action plan MPH (4 M/S) MPH (9 M/S) MPH (13 M/S) MPH (18 M/S) MPH (22 M/S) MPH (27 M/S) 7. Above 60 MPH (>27 M/S) iii. Training/Communication: It must be clear to all relevant parties what actions are to be taken and at which thresholds as identified above. This communication must take place prior to the event. b. RESPONSIBILITY: i. Individuals responsible for various tasks must be identified prior to event. This must include, but is not limited to: 1. Wind/weather monitor; 2. Stage Manager; 3. Security Personnel; 4. Artists Representative; 5. Promoter Representative; 6. Stage vendor crew lead; ii. Additionally, if a specific chain of command to any of the key responsible positions is in place, then all individuals in the chain must be aware of their immediate supervisor; iii. The contact information for key responsibility positions including names, phone numbers and work locations must be provided prior to event. c. SUSPENSION: The roof owner, Production Manager, Promoter, or state/local authorities can make the final decision to suspend the event if the public safety is jeopardized for any reason. Page 3 of 6

4 The method of initiating the event suspension must be outlined explicitly prior to the event allowing for immediate action if required. d. CANCELLATION: The roof owner, Production Manager, Promoter, state/local authorities can make the final decision to cancel an event based on inclement weather. The method of initiating the event cancellation must be outlined explicitly prior to the event allowing for immediate action if required. Page 4 of 6
