ICD are brownfields engineering specialists

driving innovation in energy, resources and heavy

industry.

Our in-house Geospatial team conducts

cadastral, civil & construction surveys, 3D laser

scanning and drone inspection, both as part of

larger ICD projects, and as stand-alone projects.

Scan data can be integrated with CAD designs

for enhanced designs and forms a basis for VR

models.

Project overview

The reason for this presentation is to

encourage other surveyors to participate in

similar projects to produce positive outcomes

for people adversely affected by bush fires

and other natural disasters.

Any Surveyor, at any time, anywhere in the

world, after any natural disaster can repeat

this project and achieve the same results.

Project Achievements • Protection of sub-surface survey marks,

• Sharing the history of the cadastre with the

residents,

• Demonstrating the use of surveying equipment

old and new

• Discussing the hardships endured by the early

surveyors

• Engaging the fire affected residents in such a

way to get their minds away from the

destruction that surrounds them - providing a

distraction and some breathing space

• Listening to their stories and experiences, giving

where possible, providing encouragement

Project Achievements • Taking the GPS and an owner on an adventure to

find the rock mark,

• having a couple of covid safe BBQ’s whist

demonstrating survey equipment and techniques

used by surveyors over many generations,

• Providing survey specific reading material so the

residents can discover more about how their land

was measured & marked

• Placing and coordinating permanent survey marks to

AUSPOS requirements for inclusion in the state coordinate data base

• Preparing a 'plan of survey information only' showing

the relationship of all survey marks found and placed

• Allowing others to engage in the project through

their generosity by providing materials and resources.

Conclusion

Some of the owners and residents of Mt

Tomah, who were adversely affected by the

bush fire on 15th December, 2019 have re-

engaged with their land through their

involvement with surveying and the discovery

of the cadastral history of their properties.
