Survey & Design Operations.

In response to client's increasing requirements for accurate and detailed 'as-built' information Ching Contracting purchased a Topcon electronic total station in 2004.

We subsequently followed this up with the purchase of the Civilcad CAD software to enable us to efficiently upload and download data into the total station and to edit and format captured field data into formats required by our various clients.


We quickly saw the advantages of being able to capture as-built data quickly and accurately and it has become our preferred method of collecting and providing information to the majority of our clients, 'raising the bar' from the traditional hand drawn and dimensioned sketches or marked up contract plans.

As our staff became more familar and skilled with the survey equipment and CAD software we could see opportunities to be able to offer a number of our clients our ability to quickly and accurately capture field data that could be used in the design of proposed works. This was particularly so for contracts we undertook for the Department of Conservation in remote locations where our survey equipment was utilised to survey other nearby sites while we were in the area surveying completed works. This data enabled accurate design and scheduling of work in remote sites which would ultimately provide DOC with better pricing from contractors who were now able to estimate with less risk, having detailed designs rather than broad concept plans to estimate from.

This has now progressed further to the point where Ching Contracting are able to offer full design and build solutions to our clients on some small to meduim sized projects, giving them a 'one stop shop' option from concept to completion and the inherent efficiencies and savings this can provide.

We have now completed a significant number of small to medium design & build projects for the Department of Conservation, Tasman District Council and private clients.

In 2016 we invested in the latest of construction survey equipment with the purchase of a Leica GPS rover and GPS base station. Along with this we upgraded our software to the latest incarnation of the Civilcad programme, Magnet Office. We have since upgraded our base station to be able to operate as a second GPS Rover unit. Utilising the Smartfix GNSS Reference Station Network we are able to receive real-time kinematic (RTK) correction service over the internet providing cm level real-time kinematic corrections in NZ GD2000.


This technology has further enhanced our abilities to rapidly capture and setout information on site with the added advantage of it now being an efficient one person operation. The GPS equipment has dramatically enhanced our ability to be able to undertake earthworks with complex and varied design profiles without the need for constant external surveyor input. This has been no more dramatically illustrated by the recently completed 3 Ridges Subdivision where the earthworks was constructed almost entirely by our operators using our GPS rover.
