Radar Tower Repairs, Supply and Installation of Two Ablutions Blocks

Project Overview

The works consisted of full encapsulation, abrasive blasting and re-coating of the radar tower structure.

The works covered the supply of two unrelated ablutions blocks at RAAF Base Darwin: one within Transit Camp 2 (ie. “Tin City”); and the other adjacent to a training room recovered from IDC Berrimah.

Challenges

• Radar Tower
  • Complex scaffolding including offset standards and cantilevered platforms above 20m required to access the tower structure
  • Pressurisation of the pedestal (lube) room to eliminate ingress of grid dust and grains
  • Care around operating RADAR waveguide
  • Maintaining maintenance access for RAAF RADAR technicians
  • Managing RADHAZ while working just below the radome itself
• Ablutions
  • Implementing PWD within the existing site layout including maintain required clearances
  • Relocate a working fire panel without an outage

Successes

• No LTIs
• No impacts to air traffic control operations
• Delivered PWD enabled facilities at RAAF Base Darwin
