brief

CBL were required to replace the fire-damaged roof and structural elements above a busy working waste processing area without affecting the operational activities.

sustainability

Utilising structural engineering disciplines to design a protective barrier for the workforce and live operational activities below. This was achieved by forming a physical crash-deck fixed to the underside of the existing roof structure.
90% of fire damaged materials were segregated and recycled. All new roofing materials were carefully sourced from manufacturers committed to achieving zero net carbon emissions.

works included
  • Full design of suspended scaffold and crash-deck system
  • Removal and replacement of fire damaged roof and cladding
  • Replacement of damaged structural sections
  • Installation of new ventilation
