General: Fabricate all boom gate components to designs and sizes indicated. Sizes of gate and profile requirements of fittings and hardware are indicated on the drawings.

Prefabrication: Complete fabrication, assembly, finishing, hardware application and other work to the greatest extent possible before shipment to the project site. Disassemble components only as necessary for shipment and installation.


General: Automation of boom gates if required will be to required operation standard based on top or mid tier equipment. Top tier relating to automation equipment with the boom gate arm weight, speed and operation frequency well within specification. Mid tier relating to less stringent or frequent operating environments.

Standards: Equipment is to comply with all relevant and electrical and safety for the legal jurisdiction of installation.



Examine footing with the installer, present for compliance with requirements indicated, installation tolerances and other conditions that affect the installation of all gates such as wind loadings.

Correct unsatisfactory conditions before proceeding with the installation.

Do not proceed with installation until unsatisfactory conditions are corrected.


Install boom gate and associated components in accordance with manufacturer’s printed instructions and recommendations.

  1. Verify units level, plumb and true line.
  2. Lubricate hardware and other moving parts.


Concrete and reo foundation design must be certified by a qualified structural engineer to meet relevant portions of the Building Code of Australia and relevant Standards Australia codes for structural adequacy in particular AS 1170, AS 2870, and AS 3600.
