New Zealand is no stranger to seismic activity.

We experience over 14,000 earthquakes a year. It’s little wonder that we’ve earned the title "The Shaky Isles". While only 150 are actually felt, the structural integrity of buildings needs to be monitored meticulously and frequently.

Founded by experts in the stabilisation of earthquake-prone buildings, Seismic Performance specialise in identifying and implementing remediation works to earthquake-prone and earthquake risk buildings.

Seismic Performance will help you ensure your building is safe, and help you save significant insurance, and financing costs in the years ahead.

On 22 February 2011, New Zealand experienced its 2nd most deadly earthquake. The magnitude 6.3 quake struck the Canterbury region, killing 185 people and injuring 2000. It caused an estimated $15billion worth of damage, making it the world’s third most costly earthquake event in history.


We specialise in the identification and implementation of remediation works to earthquake-prone and earthquake risk buildings under Building Policy 2011 2016.

We assess the seismic performance of all buildings, including those deemed to have non-ductile columns, and historical pre-1933 unreinforced masonry buildings.


We can provide the following services:

  • An Initial Evaluation Procedure (IEP). This will provide local authorities with the correct information in relation to your building for their PIM file.

  • A full Detailed Engineering Evaluation (DEE). This will provide you with the scope of works to bring your building up to the minimum seismic strengthening level of 70% to meet bank and insurance requirements.

  • A design solution to retrofit your building whilst occupied so there is minimum loss to your income stream.

  • A detailed fixed cost bid to achieve the seismic retrofit of your building.

  • An excellent source of funding to undertake the seismic retrofitting of your building.

  • Full CCC signoff off for all stages of the works undertaken acceptable to your bank and/or insurance company.

  • Full indemnity insurance, and bonds upon request.


The IEP Assessment compares existing building’s % of structural earthquake strength relative to New Building Standard (%NBS). SPL’s extensive seismic retrofitting engineering experience can help access a range of options available based on IEP grade structures:


Earthquake prone (NBS less than 33%)

  • "Earthquake prone” implies high level of building damage is expected as a result of a “design” earthquake.

  • Building owners are granted five years to develop a plan, then a further 10 years to implement.


Earthquake risk (NBS 33% - 67%)

  • Councils will not insist on an upgrade but buildings between 34% - 67% NBS are listed as “potentially an earthquake risk”.

  • Implies high to minor building damage in a “design” earthquake.


Unlikely to be an earthquake risk (NBS above 67%)

  • Strengthening the structural components can be investigated.


We remove the stigma of owning an earthquake prone and dangerous building from Council records. Our experienced team are able to save you significant insurance, and financing costs in the years ahead.


Arthur has extensive expertise in seismic retrofitting, and renovating of un-reinforced masonry buildings. His expertise is in retrofitting occupied URM buildings (the reconstruction and seismic upgrade of earthquake at risk properties). Arthur has seismically retrofitted, and restored over 57 unreinforced buildings throughout Southern California and has owned, seismically retrofitted, and renovated the following historical buildings in Auckland:

  • Endean’s Building located at 2 Queen Street, Auckland.

  • Custom House, Auckland.

  • Landmark House, Queen Street and Durham Lane, Auckland.

  • 1 Kent Street, Newmarket (Lone Star Restaurant.)


Gary is the Auckland Council consult to the Building Control Group Northern as a structural and civil engineer processing their building consents. He assesses natural hazard Section 73 applications for individual sites. Gary coordinates the RDC Programme for assessing earthquake prone buildings for compliance with the Building Act 2004.
