The University of Queensland Saint Lucia proposed joining levels 67 and 69 together of one of their buildings via an external stair. This project involved 3D scanning/surveying technology to obtain accurate existing conditions to suit the new build. The stairs were tacked together and pre-assembled in our workshop, then through the use of Virtual Reality (VR) robotics, we were able to perform our quality assurance/inspection examinations to achieve appropriate tolerances etc prior to welding together. The installation involved utilising a 100T crane, with a 51m boom extension, 26T counterweights.
