Dumas House in West Perth was constructed in the mid 1960s and is Heritage Council of WA listed. The building has two basement levels, a ground floor with entry lobby and support areas and 14 office accommodation levels.
Over 49 years, the heat, cold, wind and rain had deteriorated the building’s exterior in its exposed position north of Kings Park, the materials had reached the end of their useful life and needed to be repaired or replaced.
Duratec and DDR were awarded the contract to complete the repairs which included the replacement of all spandrel panels, ASR treatment to all columns, improvements to the soffits, waterproofing, drainage repairs and gutter improvements.
On the narrow east and west faces of the building, damage to the glazed terracotta blocks was remedied.
Repairs were also required to the building podium which leaked rainwater into the uppermost of two basement levels underneath the building and forecourt.
