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.
