Asbestos rules weigh on owners
New measures to prevent asbestos contamination during renovations and demolitions could prove costly for building owners, but industry leaders say change is well over due.
From 4 April new asbestos regulations come into force under the Health and Safety at Work Act 2015.
Health and safety consultants report a big jump in demand for asbestos surveys of commercial buildings, but they’re also struggling to find suitably qualified staff to do the work.
The original draft regulations included a requirement that all buildings built before 2000 had a register showing where asbestos was located, but Cabinet is awaiting the results of further consultation before it decides whether to make registers compulsory.
Asbestos consultant Mike Cosman was a member of a WorkSafe stakeholder advisory group that consulted on the new regulations.
They include a two-tier licensing system to remove more than 10 square metres of non-friable asbestos, or any amount of the more dangerous friable (powdery or easily crumbled) asbestos.
Class A licences will eventually replace existing Certificates of Competence needed to remove the more hazardous material. To date Worksafe has received 457 registrations of interest for Class B licences to remove non-friable material.
Cosman said the changes were long overdue because New Zealand had been 20 years behind international best practice when it came to handling asbestos.
The onus was now on owners to find out if their buildings contained asbestos, and on contractors to ensure their processes were up to scratch. Intrusive testing might be necessary before refurbishment or demolition could start.
‘‘You might have to make holes in the cladding in order to see what lies behind,’’ he said.
‘‘It can be very expensive, but not as expensive as not doing the survey, and discovering you have spread asbestos all over your construction site, and have to stop work and clean it up.’’
Quenton Dowdell, managing director of Dowdell and Associates occupational health and safety consultants, said compulsory asbestos registers would put New Zealand on a par with the United States, Britain and Australia.
Dowdell said asbestos survey costs ranged from under $1000 to tens of thousands for multi-story buildings. He has recruited five British surveyors to meet demand, which had more than doubled in the past year.
Asbestos removal and management company ATL has also been recruiting in Europe and chief executive Brett Pietersen said it was extremely difficult finding sufficient competent staff.
‘‘In our business alone we could hire another three or four surveyors tomorrow and have them busy by the end of the week.’’
ATL’s asbestos manager, Ray Payne, said changes to the regulations could result in additional monitoring and clearance testing, adding significantly to the cost for asbestos removal.
‘‘It could be as much as $500 to $700 a day for the air monitoring. The swabs [for surface testing] will be $110 per swab ... if an independent assessor says five [swabs], that’s how many will need to be done.’’
The New Zealand Property Council’s advocacy director, Matt Paterson, said building owners with small portfolios may struggle to meet the added compliance costs. The Stonewood Homes franchise was established in 1987 by Brent and Sue Mettrick with 21 franchise locations across New Zealand. It has built close to 6000 homes.
All branches are independently owned, however, Stonewood Homes New Zealand (based in Christchurch) is the master franchisor of the Stonewood Group.
Who owns what now?
Wellington’s millionaire property magnates Michael and John Chow now own the troubled firm, with plans to turn the business around. In March, receivers confirmed the sale to Inno Capital, a com-
