The flooding made the cinema look like an “Olympic swimming pool”

Events Cinema Complex, George Street, Sydney
The Event Cinema complex is on one of Sydney’s busiest streets – George Street.

The Damage

On August 1, 2017, a burst waterpipe caused extensive flooding at the Events Cinema complex. Around 8 million litres of water flooded into Cinema 12, the foyer and the adjoining production offices.

The client’s loss adjustor first contacted Advanced Buildings with the project’s instructions on August 1, 2017.

Their main concerns were interruption to trade and damage to building’s interiors from damp and mould.

The Damage

Floor coverings, furniture, walls had all been either completely submerged and needed removal and repair. Mould contamination was a particular threat and the Advanced Buildings and

Restoration team were charged with ensuring the problem was resolved.

Cost of Building and Restoration

We estimated the initial works amounted to about $750-800K and the rebuild works to cost approximately $1.2 million.

The Challenges

Council Approvals were required before any work started

Approvals were needed for access and water removal. A temporary works permit was required to allow us to park, drop, load bins on road. This was done in conjunction with a traffic management plan and traffic and pedestrian controls.

Access difficulties

The building’s downtown location meant it was surrounded by heavy vehicular and pedestrian traffic. Our thorough approach to safety required that our people and equipment worked while avoiding any traffic interruption and ensuring pedestrian and worker safety.

Working in damp, confined spaces

The extreme damp and the risk of cross-contamination of mould was a real issue. The team used containment walls and room sealant to reduce cross-contamination between work areas. To ensure a safe work environment as remediation works took place, the team wore full-face respirators. A fresh air supply was pumped through the affected rooms to reduce the effect of contaminants.

Decontamination was a 3-step process:

  • The use of an anti-microbial
  • Application of a fungicide (Oxalic acid) to kill the mould and fungus
  • Full removal of all residues after treatment

 

Lack of good lighting

None of the affected rooms had any natural lighting. We needed to use portable, rechargeable lights before the electricians could restore the permanent lighting.

Different surfaces need to be treated in different ways

We used diluted sodium hypochlorite (bleach) to remove mould and proteins on concrete surfaces. To eradicate mould contamination on coated beams (in the roof and walls), we used an anti-microbial spray. All metal and horizontal surfaces were treated by using abrasive cleaning methods with an anti-microbial chemical. A hard surface cleaner was used to clean concrete surfaces.
