I think Gerscaff has it right, I have been at this for over 40 years and have been involved in some of the most complex scaffolds in the world in T&F and also Cuplok.
Have also been involved with some of the largest Temp roof structures using HAKI Roof a blinding piece of kit.
The last couple of years I have been involved in the uptake of HAKI Universal at QFS in London and to my great satisfaction we have completed some very complex and awkward structures, in the words of Johnny Nash "overcoming all obstacle in our way"
The future of the industry will be system, it may not be in my time but it will come. There will always be a place for T&F and there will always be scaffolds that seem easier in tube but if the roles were reversed and you started with system I believe you would think it harder to Tube a job than system.
