NSW Restorations Case Study

MOULD CONTAMINATION THREATENS TO DAMAGE STOCK WORTH $1M+
We recently worked on a site owned by one of Australia’s largest family-owned and operated retailers selling sports clothes and footwear, surf, fashion and casual gear. The retailer operates 15 retail locations across Australia and has an active online store. In February 2017, a sprinkler pipe on the upper level of the Penrith store burst. This flooded the entire retail space and lead to mould contamination. This threatened to damage stock worth in excess of $1 million. Mould also presented a serious health risk to staff and customers. Management were forced to close their doors to customers until remediation and repairs fixed the problem. The loss of trade and income for the tenant during this period was considerable. The insurance companies were also facing substantial costs. Quick action was need to prevent any further contamination. Initially another insurance builder was appointed to the project. However, as the project’s assessor lacked confidence in that appointee, they engaged Advanced Buildings to do the job.

The Damage

Our Occupational Hygienist identified the air conditioner as the source of mould contamination throughout the store. Our investigation, using a thermal camera and moisture meter, found extensive mould contamination in the wall cavity. It was clear that water had been trapped behind the walls and had seeped into the air conditioning plant room. There was extensive contamination to the walls and floors of the building. There was also a serious threat of damage to stock worth more than $1 million. We estimated that the cost to complete the project was between $800,000 to $900,000. It would take 10 weeks to complete.

The Challenges

Communicating with multiple stakeholders on a complex project Though the property was leased by the retailer, the building is owned by Dr Ed Durmush. Advanced Buildings was enlisted to act on behalf of both the landlord and tenant in this claim. There were multiple insurers involved. Crawford & Co represented the retailer’s contents insurance. Stock insurance was represented by Triton Global Pty Ltd and insured by Berkshire Hathaway. Cunningham Lindsey represented the landlord on building insurance which was insured by CGU. We ensured all parties were kept informed of the job’s progress. A tight timeframe and limited hours of operation Every day the shop was closed for business cost the retailer thousands of dollars in lost sales. As this business interruption cost was being paid out by insurers, they were also keen to see the problem solved and the retailer back to normal. As requested by the retailer, we were only allowed to work Monday to Friday. Not a speck of mould could remain Our biggest challenge was to make sure that we remediated and treated the mould throughout the store, especially in the air conditioning ducting. Even a small amount of remaining mould could threaten the building and the retailer’s stock.

Structural Restoration and Cleaning

The project was carried out in stages. We divided the store into several zones, setting-up protection and containment areas. This process allowed us to leave the stock on-site, avoiding the additional cost of packing, removal and storage of the stock and contents.

The team installed protective walls to create containment zones throughout the premises. A walkway was also installed, running from the front to the rear of the store. This allowed for easy disposal of all debris via the loading dock.

Once all containment zones had been built, we were ready to work in the first zone. Our first step was to treat the empty section, then the section which the stock and contents had been moved to. The process of ozone treatment killed damaging mould spores and bacteria. It reduced the chance of cross-contamination as stock was being moved around the warehouse during restoration and building work.

 

  • An electrician carried out the necessary make safe requirements before we started removing the ceiling tiles and grid.
  • We installed air scrubbers and dehumidifiers to manage and control any contamination created during the cleaning up process.
  • The team removed and disposed of ceiling debris and the ceiling grid to expose the underside of the slab.
  • The air-conditioning ducting in the ceiling void was removed and disposed
  • Carpet tiles were removed and discarded.
  • All debris removed from each zone were bagged and sealed to prevent contamination.
  • Thorough decontamination cleaning of the rigid supply duct, supply air ducts, dropper boxes and all hard surfaces was carried out in each zone.
  • We removed dust and debris created by the demolition works using a high-powered HEPA (high-efficiency particulate air) vacuum.
  • We applied anti-microbial treatment to all surfaces in each zone. We continuously monitored and recorded moisture readings.
  • All mould remediation works were carried out in accordance with IICRC S500 and S520
  • As each zone was decontaminated, our colleagues at SLR Consulting took samples and tested to ascertain a clearance certification.
  • Once the Occupational Hygienists had checked that all contamination had been removed, stock and other building contents were returned to their original position.
