Laser Scanning

Cheal provides fast efficient data capture for design and modelling in 3D. This leading edge technology collects massive amounts of data over complex structures or surfaces in very short time frames. The technology is used for dam face and crest surveys, draft tube as-builts, steam pipe as-builts, deformation modelling, tunnelling, mining surveys, airport runways and buildings, as-built refits for ships as well as existing buildings and high rise commercial blocks, as-built data for archival record and set out of complex structures.

Steamfield Engineering

Civil and structural design of geothermal steamfield developments including grading design for the pipe corridor, stormwater design for the resulting corridor, culvert and bridge structures where conflicts occur, retaining or fill embankments as required, foundation design for steam pipes and the design of service roads and their stormwater controls.


Specialist survey services including; laser scanning, engineering survey for power station and infrastructure setout, deformation monitoring, erosion monitoring and hydrographic survey.

Cheal and Iron Man

Cheal has a long association with Iron Man New Zealand on a volunteer basis and our employees, their friends and family get involved every year for the event in Taupo. It is not unheard of for the occasional employee to decide to participate as an athlete and in the past, Ian Gray and Tom Bland have both crossed the finish line.


Gareth Dunn

The Diploma is provided by Infratrain and endorsed by the NZIS and is aimed at candidates who are employed within the industry, gaining credits through practical experience and studying for unit standards. Gareth Dunn from the Cheal Taumarunui office was recently awarded a Scholarship by the New Zealand Institute of Surveyors for his studies toward the National Diploma in Surveying.
