    VMS Gantries

    This project involved the design of a new 6m high gantry/bridge to span approximately 55m, supporting two variable signs (VMS) and one static sign for Vic Roads. An extension to an existing gantry was also designed (see photograph). The gantry/bridge included a walkway along the entire span, and comprised the following:
    • Structural steel design to AS 5100 and AS 4100 for gantry structure for dead, live and wind loads
    • Dynamic analysis of the structure to ensure safe operation
    • Steel connection design to AS 4100 and AS 5100
    • Provision of assembly and fabrication drawings for steelwork
    • Concrete footing/pile design to AS 3600 with construction drawings
    • Provision of structural certification for the gantry/bridge
    • Design and drafting of access ladder and cage, including shop drawings for fabrication purposes
