Tunnelling surveys
Years of experience in tunnelling has placed us at the forefront
of tunnel surveying. Our reputation for excellence second
to none.
In this specialised field, we carry out tunnel surveys to
locate and/or lay out a tunnel’s position. We also use our
calculations to assist a tunnel boring machine to find the
correct direction.
Major projects include:
- Sydney’s Cross Sydney tunnel
- the Bondi RIAMP sewerage treatment tunnel
- M5 East in Sydney
- North South Baypass tunnel in Brisbane
- Transgrid cable tunnel in Sydney
- City West cable tunnel.

and tunnelling projects.
Topographical
surveys
We carry out a topographical survey to gain accurate mapping
of all types of terrain. From small lots for development application
purposes to large subdivisions and highways, we can prepare
the required topgraphical data needed for your project.
As-built surveys
We carry out as-built surveys as the project progresses
and compile reports and models to coincide with project milestones.
Upon completion of the project, we compile all as-constructed
data, reports and models and present them in final document,
such as:
- 3D CAD model of as-builts – formats: .dwg, .dxf, 12D ASCII
or .mos
- a set of as-constructed plans in hardcopy and/or PDF
- a set of conformance reports in hardcopy and/or PDF.
We will provide certified drawings to you and your client
as per your specified contractual obligations.
