Alpine MDF Annual Shutdown 2024

As part of Alpine MDF’s annual maintenance shutdown program, the First Scaff team was engaged to provide access for the relagging of the multicyclone flue section located 36 metres above ground level.

The project required an intricate spurred and hung scaffold system to allow safe access for multiple trades while ensuring full debris containment through encapsulation. All works were planned and executed under First Scaff’s CM3-certified OH&S Management Plan and in compliance with AS/NZS 1576 and AS 4576.

36 m

Containment

Full encapsulation for debris and dust control

Safety Systems

Static line and harness used for initial access setup

Equipment Used

Crane, EWP, rope lifts

Compliance

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

Access Method

Staged installation via static line and harness

Application

Access for relagging the multicyclone flue section during annual maintenance shutdown

Site Type

Manufacturing plant (Wangaratta)

Key Challenges / Constraints

Limited access, restricted shutdown windows, high-heat environment

Environmental Control

Full encapsulation for debris and dust control

Project Environment

  • Limited initial access: There was no safe point from which to take accurate measurements, so much of the design and planning was completed through estimation prior to entry.
  • Restricted shutdown window: Access was granted for only one day each month while the plant was offline, requiring staged installation over several months.
  • Extreme operating conditions: The flue section reached high temperatures when operational, preventing continuous work and demanding strict safety sequencing.
  • Complex logistics: Scaffold components were lifted into place using a combination of EWP, crane and rope systems to overcome limited ground access.

Project Outcome

Despite the challenges, the scaffold was completed safely, efficiently and fully to code. The system enabled maintenance crews to complete relagging works on schedule, providing stable, debris-free access at height within the client’s shutdown constraints. The project received positive feedback from on-site supervisors and exceeded expectations for both build quality and trade usability.
