The presentation was concluded with advice for these budding young individuals

“the future is moving faster and faster, in my 30 years of experience things have moved from hand based estimating to fully computerised, drawings have moved from hand drawn taking days to complete to CAD drawn now to BIM, the future, 3D real time drawings that from the demonstration projects we have seen see construction time and site disputes reduced by over 20% and sees engineers of all disciplines being involved much earlier in the design process, this is the future with a massive need for well trained and competent engineers of which there is a great shortage”
