The Invercargill System Specifications

Tiered Light Weight Seating Structure System

This modular seating system is idea for arenas, sporting venues and other facilities, where a flexible fast turn around grandstand seating solution is required.

The Invercargill features options of:

• Albany Arena and other exceptional seats
• Upholstered Albany Arena Stadia seats
• Hot dipped galvanised or powder coated steel work
• Non slip granulated carpeted walkways

Layout configurations can incorporate corners, control positions, lighting towers, hospitality boxes, side or rear stairs.

The System

• The system incorporates a number of row options up to 30 rows in varying riser and row spacing configurations.
• The system comprises a series of stackable modules, comprising a base module (BF) and an upper module (TF)
• The TF modules (TF1 – T4) are fitted with the seat and are located on top of ta series of base modules (BF1 -BF3).
• The building blocks of a TF and BF modules are fork lifted into places in sequential manner and are linked together by a quick bolt connector.
• Each module is nominally 5.3m in width and 1.7m in depth.
• The system comprises five (5) individual section nominally 5.3m in width, joined together to form one seating bank, nominally 26.6m in width.
• Removable side and rear hand rails are provided.
• Seat options are Albany or Solara Plastic Seat.
• Aisle are nominally 1.0m in width with half steps.
• All under-structure members are hot dipped galvanised for extended life protection, as well as being colour coded for ease of sequential installation.
• The system is available in varying platform and riser height configurations.
• The system features an 18mm exterior grade plywood sealed and finished with an embossed slip resistant surface finish.
• The system can be stored outdoors without any protection from the elements.
• The system is modular and designed for rapid install by a Team of 4, utilising a fort truck and with accessible access from the storage area, a 1000 seat system can be installed in four (4) to five (5) hours.
• The design and linking of the system mean unskilled labour under stadium supervision can be used.
• The system is strong, robust and meets all safety, weight and loading standards, yet because of its design, utilises light weight constructions principles.
• The system with the use of additional side and rear handrails, is ready adapted to different seating module configurations.

Design Criteria

• The occupancy class is public assembly, as specified in AS1170-Part 1 – 1981.
• Live Loading of 4k N/M2 for fixed seating.
• Live Loading of 5K N/M2 for gangways, stairs and landings.
• Bracing is designed to support 5% of the vertical load to accommodate spectator induced horizontal surge loads as specified in BS5973-1981.
• In addition for outdoor application, wind load considerations are specified in AS1170-Part 2-1983, have been considered.
