Kevin McAlpine


"I had the pleasure of working with the team Civil Geospatial Services (CGS) for many years and across multiple sectors . In my experience, project success is largely based on the accuracy of the survey set out and pick up – particularly the exceptional quality CGS provide every time! CGS are also at the forefront of ever-advancing technology and have successfully utilised drone flights for material movement reconciliation on the delivery of 85km of civil construction on the Carmichael Rail Network project in central Queensland. I am proud to consider CGS a key partner in the exceptional growth of Martinus now and into the future."

The services provided have been professional with reliable and experienced personnel with current Survey Technology always being utilised. This has benefited McConnell Dowell by eliminating costly rework during construction and the ability to provide rapid project close out as survey data quality and accuracy is always ensured."

"I have had the good fortune to work with CGS for Martinus Rail on the Adani / Bravus Carmichael Rail Project . I found CGS and their staff easy to communicate with and able to discuss the complexities of the project. Tony and his staff are hardworking and do long hours to achieve the best outcome for the project in a very professional manner. I highly recommend CGS to work on any project that requires long hours, complex challenges. I would be happy to work with them again in the future."
