JMB was called to site recently when suspect mould was identified during renovations of an iconic Sydney property. The construction company engaged to upgrade the building internals had uncovered visible growth behind wallpapers and partition walls.
Our initial inspection identified widespread mould issues, with elevated quantities of mould types associated with water damage, such as aspergillus like and Stachybotrys, the latter of which is known to produce Mycotoxins and is regarded as harmful to building occupants. The cause of the mould was isolated to roof leaks and poor sealing of wet areas.
Following our inspection and report, JMB prepared a thorough Mould Remediation Control Plan (MRCP). The document provided details such as large-scale negative pressure containment set up, number of air changes, transit routes for waste, correct Personal Protective Equipment (PPE) etc, plus highlighting the process of remediation that would lead to successful Post Remediation Verification (PRV) at the property.
The MRCP was successfully delivered to the contractor engaged to undertake the works. As it was necessary to keep parts of the property open to the public, during remediation JMB were engaged to conduct grab sampling and pressure testing to qualify controls and confirm visual integrity inspections of the containment. Similar to correct asbestos control monitoring, this sampling program provided extremely useful data and allowed us to identify any containment leaks quickly. It also kept the project on track and assisted by mid-PRVs or ongoing assessments within the enclosures led to successful PRVs.
If you suspect that you have a mould and moisture issue, contact JMB Environmental Consulting Pty Ltd and we can send out an experienced indoor environment professional to assess your property, quantify and risk assess the mould to surfaces and in the air, and identify potential causes to assist with rectifying the problem. Alternatively, our in house EmPAT accredited mould laboratory can provide analysis for your mould sampling needs.
