How many earthquake prone buildings are there in Wellington?
eight earthquake-prone buildings
There are currently eight earthquake-prone buildings in Wellington with expired deadlines. The council is focusing its efforts on the highest risk buildings, being the two before the courts. Five of the buildings have work underway and one, a car repair shop on Coutts St, is considered relatively low risk.
Is Wellington earthquake prone?
It is well documented that the Wellington region has potential earthquake risk, with a number of active faults identified in the area. In particular, how buildings perform during earthquakes.
How do you know if a building is earthquake proof?
Using the Department of Building and Safety website, you can easily check to see if your building is on that list. Just enter your address into the search tool and click on the “Soft-story Retrofit Program Information” button once your building’s information appears.
How do I find my NBS rating?
Not sure what your building’s NBS rating (or Earthquake prone rating) is? You can now easily find it out online, as The Ministry of Business Innovation and Employment has released a new online tool called the Register of earthquake-prone buildings (EPB Register). You can check it out here.
What does 67 NBS mean?
Earthquake Risk Building
A building rating less than 67%NBS is considered as an Earthquake Risk Building (ERB). They can be occupied, it’s just a question of safety and managing risks. There are consequences under the Health and Safety in Employment Act if owners or occupiers don’t take practical steps to minimise ‘hazards’ in the workplace.
Is Palmerston North earthquake prone?
Palmerston North is classified as a ‘High Seismic Risk’ area, meaning it has the shortest timeframes in the country to address earthquake prone buildings. As well as being a landowner, Council is responsible for the administration of these earthquake prone building provisions of the Building Act 2004.
What is an earthquake prone building?
A building, or part of a building, is earthquake prone if it will have its ultimate capacity exceeded in a moderate earthquake, and if it were to collapse, would do so in a way that is likely to cause injury or death to persons in or near the building or on any other property, or damage to any other property.
Do buildings collapse during earthquakes?
Most collapses that occur during earthquakes aren’t caused by the earthquake itself. Instead, when the ground moves beneath a building, it displaces the foundation and lower levels, sending shock waves through the rest of the structure and causing it to vibrate back and forth.
What does 34% NBS mean?
What does an NBS rating mean? “The 2004 Building Act states an Earthquake Prone Building is one that would be likely to collapse in a modest earthquake. Existing buildings must be at 34% of New Building Standards (NBS) when it comes to earthquake strengthening – anything lower than that requires an upgrade.”
Whats a good NBS rating?
The basics A building with a 50%NBS seismic rating would be expected to withstand, to a similar level of reliability, a one-in-100-year quake (the scale is exponential). Above 67%NBS, a building is considered to be an acceptable seismic risk by the New Zealand Society for Earthquake Engineering (NZSEE).
