Mt Hotham Resort – Tank Access Bridge Project

First Scaff was engaged by Mt Hotham Resort Management to design and construct a scaffold system providing safe access into a new water tank during construction.

The project required a complex scaffold bridge with a stair system that rose approximately 6.5 metres over the tank wall before descending internally, complete with a working platform, handrails and edge protection.

This structure enabled trades to safely carry out critical works within the tank during the build phase. Once complete, the scaffold bridge was craned out to allow civil crews to pour concrete and install formwork before being lifted back into position for further internal access.

Technical Scope

Scaffold Type

Stair and bridge scaffold system

Height

6.5 m above tank wall

Equipment Used

Crane, harness systems, preassembled scaffold bridge

Compliance

CM3-certified OH&S Management Plan; AS/NZS 1576, AS/NZS 4576, AS/NZS 4994 and AS 1657:2018 standards

Access Method

Crane-assisted installation and removal

Application

Safe access for internal tank construction

Site Type

Alpine construction site (Mt Hotham)

Key Challenges / Constraints

High winds, variable weather, precision craning requirements

Environmental Control

Weather monitoring and site safety procedures for alpine conditions

Project Environment

  • Precision engineering: The scaffold required exact measurements to ensure it could be craned in and out without modification or adjustment.
  • Environmental exposure: The site’s alpine location presented high winds, cold temperatures and variable weather, increasing complexity during installation and lift operations.
  • Craned positioning: The entire access bridge was pre-assembled and lifted into place using a crane, requiring careful weight distribution and sequencing to maintain structural integrity.

Project Outcome

The scaffold bridge was successfully installed, removed and reinstalled without incident, providing stable and compliant access throughout each phase of construction. Despite the challenging site conditions, the project was delivered safely, efficiently and within the tight tolerances required for crane-assisted positioning. The system enabled uninterrupted work for multiple trades while maintaining site safety and compliance standards.
