NZIS Report Released - Review of Survey Practices in Relation to the Canterbury Rebuild

The New Zealand Institute of Surveyors (NZIS) has released a report titled: Review of Survey Practices in Relation to the Canterbury Rebuild.

In February of this year, NZIS formed a Working Party (WP) to look at survey practices after concerns were raised about the measurement of earthquake damaged buildings in Canterbury.

The WP was led by Emeritus Professor of Surveying, formerly of the University of Otago, John Hannah and consisted of Registered Professional Surveyors who provided a strong mix of academic and professional practice experience.

The Working Party focused on reviewing the Ministry of Business, Innovation & Employment (MBIE) guidelines relating to the measurement of floor levels of earthquake damaged buildings and an investigation of the measurement methodology and practices that have been applied in Christchurch.

Extensive consultation was undertaken with the MBIE, NZIS members and various interested industry groups.

The report outlines the Working Partys findings and describes best practice procedures for levelling, including those needed for using the Zip Level Pro-200 Altimeter.

Andrew Stirling, NZIS Chairman, is pleased at the results gained around a very technical issue.

The Working Party has focused its efforts on practical solutions to what is a complex issue for practitioners involved in the Canterbury rebuild. We are pleased with the recommended methodology and guidelines resulting from sector input and fully support the content of the final report said Mr Stirling. It contains important guidance, from the experts in measurement, to anyone involved in earthquake damage assessment.

Adrian Regnault, General Manager, Building System Performance, MBIE, supports the institutes initiative to review measurement procedures.

The Ministry welcomes practical suggestions on how the guidance may be improved and will give careful consideration to all recommendations made by the working party.

The original intent of the guidelines was to get information out to the sector as soon as possible to facilitate the rebuild but the guidelines have evolved considerably since the first edition in December 2010. Ongoing sector input ensures our guidance will continue to give robust and well-balanced engineering solutions that will reduce the risk of injury to people and damage to homes in future earthquakes.

The entire report can be viewed on the NZIS website Advocacy page.
