DCC releases earthquake-prone buildings register

█ Electronic copy of the register (via LGOIMA) can be viewed at Comments.

Owners of all non-residential, pre-1976 buildings had until the end of next year to have their buildings assessed and report results to the council.

Tip of quake iceberg released
By Chris Morris
A register of Dunedin’s earthquake-prone buildings has been made public for the first time, but it is likely to represent only the tip of the iceberg, the Dunedin City Council says. Council staff, responding to an Otago Daily Times request, have released details of four earthquake-prone buildings in Dunedin, as well as another 44 considered likely or possibly so.

DCC webpage: Earthquake strengthening
‘Earthquake strengthening’ improves a building’s ability to withstand the effects of earthquakes and, most importantly, improves the safety for those in and around the buildings.
Due to the age of Dunedin’s building stock and the large number of unreinforced masonry buildings in the city, many of the city’s heritage buildings are currently ‘earthquake–prone’. In 2012, owners of buildings in Dunedin will receive letters to advise them of the need to have their buildings inspected by a qualified structural engineer to assess their potential performance in an earthquake. These assessments will be recorded in a Council register. Building owners will be given a set timeframe in which to upgrade their buildings. Notwithstanding this timeframe, building owners undertaking other significant improvement work or a ‘change of use’ of a building will be required to complete earthquake strengthening as part of that work….

Claudio Modena 2Claudio Modena is a Professor of Structural Engineering at the University of Padova, Italy (1994–). He has presented the course of “Structural Problems of Monumental Historical Heritage” in Architectural and Building Engineering and is Director of the Masters course in ‘Structural Restoration of Historic Monuments and Buildings’.

Author of over 200 papers in international journals and attendances at conferences, Claudio Modena is interested in analysis and design of construction, with particular attention on:
– masonry of historical and monumental structures
– strengthening/retrofitting in seismic areas
– retrofitting of metal and masonry arch bridges, and
– safety evaluations.

The professor has maintained a balance between academic and practical experience, combining with mutual benefit both research work and technical consulting. Most of his consulting activity is in the field of restoration and conservation of historic masonry structures.

Claudio Modena is a member of several technical and scientific committees: Cultural Heritage Ministry, Protection of Cultural Heritage from Seismic Hazard Committee. He is currently a member of the High Risks Committee – Seismic Risk Sector of the national Civil Protection Agency and of the special committee established by the Ministry of Infrastructures and Public Works for re-drafting the national codes system related to structural safety of both new and existing structures.

Enhancing building performance #eqnz

Knee-jerk reactions to government proposals are hardly necessary at Dunedin, the DCC’s earthquake-prone buildings policy has already been launched.

DCC Earthquake Strengthening + Policy

ODT 8.12.12:
Dunedin City Council [policy planner – heritage] Glen Hazelton said the Government’s proposals were “pretty much in line” with the council’s existing policy. That policy required owners whose buildings were found to be less than 34% of code requirements to upgrade. Owners had between 15 and 34 years to do so, depending on the state of their building, meaning some would face shorter timeframes under the Government’s proposals than they had expected, but not extra costs. The most earthquake damage-prone buildings had faced the shortest timeframes anyway under the council’s policy. The council had warned owners of the possibility timeframes would be reduced from 34 years.
The council’s own buildings – including the likes of the Town Hall, Municipal Chambers and Railway Station – were already having their earthquake strength tested, council city property manager Robert Clark said. That work began early this year and up to 30 written reports on individual buildings were expected by mid-next year. Some, such as the Municipal Chambers, had already been strengthened, while others, like the Railway Station, were considered to be of sturdy construction, but were being checked, he said. Results were yet to be made public, but buildings appeared to be “measuring up at the moment”, reaching 66% of the building code or even better, he said. The council already faced extra costs, having initiated its own checks, but it was “appropriate” to do so and ensure the health and safety of staff and the public. He expected the checks would meet the requirements of the Government proposals, although detailed information was yet to be received. Mr Clark doubted buildings would need to be abandoned or demolished.

Earthquake changes could cost $1.7bn
By Isaac Davison
Uncompromising proposals to eliminate or strengthen earthquake-prone buildings could change the face of character areas such as Mt Eden’s Dominion Rd, and cause complex disputes in high-rise apartments owned by multiple parties. The Ministry of Business, Innovation and Employment has proposed seismic assessment of all commercial and high-rise, multi-unit buildings in New Zealand – believed to be 193,000 properties.
Those that were not upgraded to withstand a moderate-sized earthquake within 10 years of assessment would be demolished.
The Government proposals were in response to a Canterbury Earthquake Royal Commission report on quake-prone buildings, released yesterday. The ministry broadly agreed with the Royal Commission’s recommendations, but it proposed more lenient timeframes for strengthening and did not agree that the minimum threshold for remedial work should be raised. Housing and Construction Minister Maurice Williamson said to do so would impose “catastrophic” costs on society.
The Government proposals have been released in a consultation paper. If they are adopted, the cost of the changes would be borne by councils and property owners.

Only 39 people died due to unreinforced masonry buildings at Christchurch, that’s remarkably few given the age and size of the city, the population size and concentration, and the extent of devastation caused by the quakes.

Most NZ buildings to be quake assessed
By Isaac Davison
All non-residential buildings and high-rise, multi-unit apartments in New Zealand will be assessed for earthquake risk and the results made public under Government proposals released this morning.
Any building found to be at risk of collapse will have to be strengthened or demolished within 15 years under the proposed changes, which form the Government’s response to a Royal Commission investigation into earthquake-prone buildings after the Canterbury quakes.
The Government planned to adopt many of the commission’s recommendations, but has chosen longer timeframes and lower minimum standards of building strengthening than the report proposed.
The commission found there was poor information on earthquake-prone buildings in New Zealand, lack of central guidance on defining and repairing these structures, and variable council approaches to fixing the problem. Only 23 of 66 local authorities were able to tell the commission how many earthquake-prone buildings were in their area.
