Secretary for Development Bernadette Linn on Saturday said that more than 10,000 new pieces of mesh netting were currently undergoing laboratory testing and would be distributed to building contractors next week for use if they pass muster.

The government ordered the removal of all mesh netting on buildings undergoing major renovations across Hong Kong last month, citing public safety following the deadly fire at Wang Fuk Court in November. The blaze's rapid spread suggested non-fire retardant netting was a contributory factor.

It introduced testing requirements for every batch of mesh netting, with the Construction Industry Council tasked with verifying directly with laboratories on its suitability under a new tracking system.

Under the new regulations, contractors must submit new testing results for mesh netting to the Buildings Department within 12 months.

Speaking on an RTHK programme, Linn said such a time frame was adequate given the responsibility contractors bear for ensuring the safety of the materials they use.

"Contractors monitor site operations at buildings daily. If they see a net that has suffered damage for any reason whatsoever, they should not wait until the 12-month limit to do testing," she said.

'We hope contractors will pay attention to construction materials used, such as whether they are still safe to use."

As for netting samples taken in December from more than 400 buildings undergoing major renovations, Linn said no results were available yet due to the repeated testing procedures they had to undergo in case they might be used as evidence in prosecutions.

Separately, Linn said the government was putting together a management board for the company to oversee an industrial park in Hung Shui Kiu, which would be part of the Northern Metropolis project.

Linn said the company would be expected to submit a development plan and work report yearly, and report to the Legislative Council.

Another two pilot sites in the area will be put up for tender in the second half of the year, she said, while the administration expects to pass dedicated legislation to accelerate development of Northern Metropolis this year, following public consultation and Legislative Council readings.
