Mt Bold Inclinator Project

The project was delivered under an ‘Early Contractor Involvement’ (ECI) delivery model and involved the design and construction of a personnel access system to the lower valve chamber at the Mt Bold Reservoir Dam.


  • ECI services including options analysis, design and costing of a suitable access system
  • Design of a monorail personnel access lift fixed to the existing dam wall at 36 degree slope angle
  • Fabrication, installation and commissioning of the new monorail lift (inclinator)
  • Fabrication and installation of upper and lower access platforms
  • Lighting upgrades to platforms


  • Safety in Design considerations for access, maintenance and personnel safety and recovery
  • Construction to take place on steep batter – working at height safety controls
  • Geometric analysis for fixing of the structure to the existing dam wall – 3D analysis
