Do you want to see undergound
Seeing is believing….
It has always been an elusive concept to see what is immediately beneath our feet.
As beings that generally inhabit the surface, we rarely consider what a valuable asset the underground offers us going forward into the future.
It is now being proposed within infrastructure planning as a serious option for future expansion and development whilst providing many benefits which are not usually considered. From an environmental point of view, the underground has the ability to provide advantages such as constant temperature, security, availability, engineering integrity, to name but a few.
This is one of the primary functions of the ATU program to determine location and condition of subterranean assets, ground condition, accurate global mapping, and geophysical issues relating to engineering, construction, transport, utilities, and street-works where advanced technologies are now being made available.
As a result, there are many new and innovative technical advances that will assist stakeholders and undertakers in making informed decisions on engineering and construction methodologies directly relating to specific geographic location. Research into passive electromagnetic techniques, non-contact electrical resistivity, vibro-acoustics, and multi sensor applications are making considerable headway in allowing engineers to capitalise on these new and significant advances.
Along with these emerging technologies we now have the opportunity of physically “looking” at materials throughout depth tied in with penetrographic information on ground resistance and materials identification. This also allows for classification of materials, determining particle size distribution, angularity, integrity, stability, moisture content, and many other applicable considerations such as reverberation, viscosity, cohesiveness, and the like.
Users will soon be able to determine and equate resistance values to a linked video allowing visual representation of encountered materials.
