Right People, Right Machines, Right Results


Aerial Scoping

Sesi has its own micro-light aircraft that can be used for scoping projects prior to commencement, during the construction phase and at the end of projects.
We can fly over a project to assist in ascertaining the cost of the project.
We can take aerial photographs for our clients.
At any stage of the project we can fly over the project site/sites before vehicular land access is approved to examine the terrain ahead and decide which machines we will require.
We can also identify hazards, difficult areas, water courses etc and plan for them accordingly, long before they would be usually be identified, thus reducing costly stand by time.
By using our aircraft we can ensure that your project runs as smoothly as possible and logistics are planned well ahead, especially compared to not using aerial scoping.

Additional survey marking

On our pipeline and powerline projects we do extra markings of the ROW in addition to the surveyor's pegs. Sometimes the scrub is heavy and the machine operators cannot clearly see where the next peg is situated.
By doing this extra marking not only does it save machine operator time but it also ensures and in most cases eliminates any breach of crossing the easement.
If an ROW crossing breach occurs, the environment or cultural heritage fines can be very costly, up to $1m for a company. However the cost of the fines can be minimal compared to the cost of down time a breach can cause. Costs of up to $150m are not unheard of.
Our process of extra marking is a very valuable service we provide to our clients.


At Sesi we pride ourselves on our close working relationships with other teams on your project.
We have the utmost respect for the guidelines of Cultural Heritage, Environmentalists and Fauna Spotters and maintain close communications with them throughout the project.
Through our communication with these teams and the survey team, we can learn a lot of valuable information to assist us in our scoping of a project, such as them advising us of relevant sites coming up or hazards etc.
It also assists us to ensure that we are operating within their regulations.
Communicating with us also assists them by informing them of any items we uncover during our scoping, such as a sacred site or an unmarked water course etc.
