- A Rigging Request form must be submitted along with a scaled rigging plot a minimum of 14 days prior to load-in. http://www.psav.com/Rigging‐Services
- Trade Shows will be subject to a $35 per point review fee.
- Production Rigging will be subject to an hourly review fee.
- Advanced Rate for plan reviews submitted no less than 14 days prior to load-in is $65 per hour with a one hour minimum.
- Standard Rate for plan reviews submitted less than (14) days before load-in is $90 per hour.
- Determination of time to review shall be at Facility’s discretion and plan re-submissions for any reason are billable.
- Rigging plots must include all flown equipment, published weights per point, final trim heights by truss line and a reflective ceiling plan.
- A weight calculation will be conducted of all rigging points and confirm adherence to the Working Load limits of the Mountain America Expo Center’s structural documentation.
- Any overweight points or unsafe scenarios will be addressed and will need to be changed, upon which the entire document must be resubmitted for approval.
- Any on-site additions or deviations from the approved plot must be reviewed and approved before implemented and flown out.
- Rigging contractor must be able to demonstrate, upon request, all equipment and labor safety requirements as detailed within this document. Any unsafe or unapproved practices will not be permitted.

- All rigging crews shall be led by an ETCP certified rigger. Evidence of current ETCP certification shall be provided to the facility at least 48 hours prior to load-in.
- Lead rigger shall be responsible for supervising crew and enforcing policies within this document.
Rigging Point Attachment & Rigging Hardware
- Rigging is only permitted on building structure that has a stamped working load limit from a PE.
- All rigging must adhere to both vertical and horizontal working load limits set by the above documentation.
- Hanging from any other objects or fabric of the facility, such as plumbing, electrical fixtures, HVAC or supporting infrastructure is strictly prohibited.
- All rigging point attachments must be created with ANSI-approved hardware.
- All hardware (shackles, pear links, STAC chain, wire rope, slings, Gacflex, etc.) must have a stamped working load limit at a minimum of a 5:1 design factor, and must be product traceable.
- Rigging Point construction standards:
- All points/ hitches require the use of either burlap or other padding to protect both facility structure and a proper D/D ratio for supporting cable. (Not needed for Gacflex.)
- Bridal points shall not exceed 120° between legs.
- All rigging points must have a minimum of 24” of clearance from every fire sprinkler head.
- All rigging points must be free and clear of any obstruction when loaded (HVAC, lighting fixtures, drywall, etc.)
Chain Hoists and Aluminum Structures (truss)
- All Chain hoists must adhere to ANSI B30.16
- Proof of annual inspection and load testing must be presented prior to load‐in

- All aluminum structures (truss) must adhere to PLASA E.1.2.5‐6
- Proof of annual inspection must be presented prior to use.
- Ground-supported systems must have known working load limits and ballast requirements in the vertical orientation.
- All truss wraps where a motor is to be attached must have a wire rope safety cable with minimal slack. (Not needed for Gacflex.)
- ALL items flown on truss must have a safety cable.
- All hardware used to suspend items must be rated hardware and used in an appropriate fashion.
Air Wall Track Hanging
- All “hangs” should be vertical “dead – hangs” only.
- The total weight of a single dead hang should not exceed more than 200lbs. Each point must be a minimum of 4ft from the next nearest point.
- No dynamic loading is permitted.
Banner & Signage Hanging
- These provisions do not apply to non‐motorized banner and aisle signs, booth lighting and signage, exhibit design, etc., whether displayed within the exhibit halls or other specified locations.
- All rigging must be completed within the confines of either a scissor lift or boom lift.
- No climbing allowed under any circumstances.
Ground Support Truss
- All trusses must be used to manufacturer’s recommendations.
- All ground support trusses must be engineered.
- All OSHA standards must be followed when working with, on or about ground support truss system.
