Bogong High Plains Road Landslip Remediation

Principal: VIDA (formerly MRPV) Value: $88 million Location: Alpine Victoria Delivery: 2023–2024 Sector: Roads & Transport Infrastructure

Project Overview

In October 2022, a significant active landslip was identified on Bogong High Plains Road between Mount Beauty and Falls Creek, resulting in the closure of a critical alpine transport corridor. The failure—estimated at approximately 70 metres high and 100 metres wide—represented one of the largest landslips experienced on Victoria’s road network in more than 40 years.
Following initial stabilisation by the Department of Transport and Planning, Whelans Group was engaged to deliver interim remediation works and ultimately restore safe, two‑lane access to this essential regional and tourism link.

Scope of Works

Large‑scale geotechnical remediation and earthworks

Removal of approximately 600,000 tonnes of unstable material

Drainage reconstruction and stabilisation works

Temporary traffic corridors and staged access management

Environmental protection and site rehabilitation

Permanent infrastructure upgrades supporting long‑term resilience

Delivery Challenges

Highly active landslip zone within a dynamic alpine environment

Significant geotechnical complexity and ongoing ground movement

Environmentally sensitive terrain requiring strict controls

Programme pressure to restore access ahead of the winter ski season

Restricted access and weather‑driven constraints

Whelans Approach

Whelans Group deployed a disciplined, integrated delivery approach combining self‑performed earthworks, in‑house plant capability and structured environmental management.

Safe multi‑front construction was maintained through detailed geotechnical monitoring, staged excavation and robust drainage controls. The project was supported by Whelans’ internal haulage capability and experienced project management team, ensuring flexibility and responsiveness within a highly constrained alpine setting.

Environmental management plans were embedded across all work fronts, with ongoing monitoring and rehabilitation delivered alongside construction activities.

Outcomes & Results

Temporary single‑lane access reinstated in April 2023

Full two‑lane access restored on 27 May 2024, ahead of the ski season

Delivery of one of Victoria’s largest landslip remediation programs

Restoration of a critical connection between Mount Beauty, Bogong Village and Falls Creek

Long‑term stabilisation and resilience improvements to the corridor
