Quick Reference - Rigging and Engineering Stamp Guidelines

Understanding and following proper rigging regulations is essential for exhibitor safety and compliance. These guidelines can vary significantly between venues, cities, and even counties, so always consult your specific show services kit for the most accurate information. Local jurisdiction codes will always take precedence over general contractor standards.

Engineering Stamp Requirements

Revised regulations state that a structure’s engineering stamp is valid if the following conditions are met:

• The stamp is issued by a structural or civil engineering firm in the United States.
• The structure has not been modified since the original design stamp was issued.
• Crucially, venue, municipality, or state codes will take precedence over General Contractor standards. If a local code is more stringent, it must be followed.

This revised rule provides much-needed flexibility, allowing exhibitors to use their existing stamped components across different shows without needing a new stamp for each event, as long as local rules don't mandate it.

Hanging Signs and Graphics Requirements

• Weight Threshold - Signs over 250 lbs may require secondary lifting devices (chain hoists)
• Assembly Restrictions - Only official General Service Contractors (GSC) can assemble, install, and remove overhead hanging elements
• Supervision Only - Your team or Exhibitor Appointed Contractors can supervise but cannot perform rigging work
• Lift Access - Only GSC employees are permitted in lifts
• Custom Elements - Lightboxes, headers, and video wall surrounds require stamped certification from licensed U.S. engineers
• Structural Integrity - All signs (except cloth banners and signs under 100 lbs, typically) must have structurally engineered rigging points
• Safety Review - All signs may be reviewed for structural integrity pre-show and during installation
• Manufacturer Compliance - Modular signage systems must use approved manufacturer hanging hardware

Video Wall Regulations

• Engineering Certification Required - All non-serially manufactured LED and video display systems need stamped engineering certification
• Standards Compliance - Must meet ANSI E1.50-1 standards
• Assembly Plan - Detailed assembly and disassembly plan must be submitted to GSC for review

Tie-Off Requirements

• Stamped Certification Needed - Required for booth elements needing venue structure support (headers, seismic lines)
• Pre-authorization Essential - Contact GSC in advance if anticipating tie-off services
• Structural Integrity Verification - Licensed engineer must affirm structural soundness.
