Renowned for innovative engineering and experience in earthquake zones around the world, Dr Miyamoto says the industry needs to take a new approach to make it more affordable for property owners to meet the new earthquake strengthening standards.
“New Zealand needs to seriously consider the need to seismically upgrade building stock in an economically feasible way,” Dr Miyamoto says.
“The Government’s initiative to tighten building standards is absolutely the right thing to do, but there will be landlords who will struggle to find the funds to afford the upgrade.
“We need to devise an action plan that achieves the right balance, and get on with the work for our buildings that do not meet an acceptable standard, as well as new construction.
“The economic viability of industrial and commercial buildings nationwide rests on turning seismic requirements into opportunities.”

At the first seminar held in Wellington recently, case studies of cost-effective and commercially viable seismic strengthening projects were discussed.
These included a Christchurch City Council heritage building — the Cashmere Hills Presbyterian Church, the Catholic Archdiocese of Wellington’s “Project Stronger”, a six-storey Hereford Street building in Christchurch’s red zone, and Napier’s Co-operative Bank building.
International examples were also presented, including the California Unreinforced Masonry (URM) ordinance, and a high-tech approach in Asia and Americas.

Dr Miyamoto also discussed public and commercial projects led by the Miyamoto team, such as the University Gateway at the University of Southern California, and the seismic risk management of the Los Angeles World Airports.
Dr Miyamoto says it is imperative that any change in seismic requirements also addresses concern around return on investment, financing and insurance for building owners.
“With proposed legislation requiring buildings that fail a seismic test be strengthened or demolished, we need to look at ways that owners and investors can manage their asset, meet the new standards and protect their buildings,” he says.

“The Canterbury earthquakes have prioritised earthquake strengthening in New Zealand, but the seismic dilemma is not new. By looking at global solutions, we are able to make the most of lessons learned in earthquake-prone regions around the world.
“There are various options that have worked abroad that have enabled investors to bring buildings up to requirements, while helping to manage the economic cost.
“Some of these have been Government-led, but many are examples of building owners and industry working together successfully to take a cost-effective, proactive approach.”
