T&G Corporation Pty Ltd can offer an on-site service to model part of, or a complete plant if required.  Where there are existing engineering drawings, T&G can produce a simplified model of the current plant and use it to design further modifications.  The T&G team will work on site to check the existing structure, using laser measurement to ensure the accuracy of the work.  The model can also be reviewed in 3D walk-through mode without going to site.
