ALUMINIUM BROADBAND TRANSMISSION TOWER FOR ELCHO ISLAND ARNHEM LAND, NORTHERN TERRITORY.
The article was published in Engineers Australia magazine in the December 2009 issue.
The tower had to be lightweight, and easily transported with small 4WD vehicles (on a roof rack) and erected without cranes. The tower was 24metres high with a 6metre wide base. It was a lattice tower designed of aluminium circular extruded tube. The tower was designed to be supported either on a concrete pad base or alternatively, on MEGA ANCHORS. Because the tower was designed to be erected in remote locations, soil testing was planned to use geophysical methods of Refraction and MASW seismic, with confirmation of the soil profile to rockline by using hand augers.
