We have just been audited by Land Information New Zealand (LINZ).
It went well.

Land Information New Zealand (LINZ) audits approximately 30 Licensed Cadastral Survey practices every year. This is on behalf of the Surveyor General and required by Section 7(1)(j) of the Cadastral Survey Act 2002. Firms are randomly selected for audit each year, and this is the first time Warkworth Surveyors Ltd, or our Licensed Cadastral Surveyor, Graeme Smith, has ever been subject to a LINZ audit!

It involved a field audit of a rural (Class B) survey and an urban (Class A) survey. They randomly selected these from the 44 survey datasets we’ve submitted to LINZ in the previous 12 months. A month later, when they’d analysed their own measurements and compared the results, they visited our office to audit our cadastral survey office procedures. This included reviewing hard copy and electronic files of the two previously selected surveys, plus two other files, selected randomly.

We won’t receive the audit conclusions for a week or so, but feedback on the day, from the two LINZ auditors, was very pleasing and very reassuring. The two surveys that were fully audited passed with flying colours (2 points on one and 3 on the other – 0 is a perfect score and 10 is a fail). The auditors were very complimentary about our office files, systems and infrastructure.

We are confident that the Surveyor General will receive a glowing report about Warkworth Surveyors Ltd!


  The Oaks on Neville   Our Surveyors Shane Sutton (left) and Simon Knight (right) have been heavily involved in the Oaks on Neville Project for the last few years. They are pictured with our Sokkia SDL30 digital level and bar-coded fibreglass staff. This equipment was used to accurately monitor the height of references pins in the pavement and buildings surrounding the project site. This was to make sure there were no issues while de-watering was being carried out during construction of the underground carpark. This level monitoring commenced in November 2014 and has been repeated at regular intervals until now. Small fluctuations of a few mm in height were observed and in general these mirrored the fluctuations in groundwater levels that the geotechnical engineers were recording at piezometer borehole locations. This enabled management of the volume of water being pumped out of the basement excavation.  Simon and Shane were also responsible for setting out grid positions, reference benchmarks and other specific features during the construction process. This was mainly for the project managers, Kalmar Construction Ltd and for the piling contractor CLL Ltd. There were also numerous requests from both Kalmar and the Oaks on Neville Ltd for urgent topographic surveys to facilitate design changes.  Warkworth Surveyors Ltd gave the Oaks on Neville project top priority in our day to day programming. We made sure there was flexibility in Simon and Shane’s weekly tasks to ensure they could be available at short notice to meet construction demands.  We are proud to have been involved in the Oaks on Neville Project.

Our latest hardware update

The Sokkia SHC5000

This new tablet recorder, incorporating Real Time Kinematic (RTK) data collection allows us to improve efficiency out in the field. Better screen illumination makes it easier for our operators to see what they are doing in bright light. Just part of our drive to stay ahead of the curve on technology.

Along with updated hardware comes software improvements. We have installed BricsCAD software at the office to improve our CAD capability. This software will improve the presentation of our final plans and improve efficiency. We like something that makes us look good.

We have also updated our Mail Manager so that all our e-mails can be referenced to individual jobs. No more hunting around trying to find an e-mail that came in about a particular project. It's all neatly filed and easily available now and in the future. That's better for us and our clients.

There have been exciting developments with drone mapping in the surveying industry. It getting easier and more affordable to get very accurate aerial surveys of our projects which can be converted to 3D fly-throughs, and other applications. We've now utilised such technology for two of our projects and are pleased with the results. The future has arrived!

And, lastly, on the project front, there is still an awful lot going on locally to keep us busy. We are just finishing up on The Oaks retirement village in central Warkworth, doing finishing touches to projects in John Andrew Drive, Warkworth, and closing off Stage 2 and opening Stage 3 of our work in Torea Rd, Matakana. There are many more projects in the pipeline so expect to see our utes and staff out and about in the field.
