hi there,
david,
we are a build clean company, as things are moving on, you will find more and more FIRST window cleaning to be done from scaffold. i expect that you are talking about the top pelmet tape, where the mastic line inserted.
I have seen people standing on milk crates etc, but if Health and safety see you, you will be off site no questions.
more and more developers are coming down a rise at a time, to accomodate trades that need extermal access, and to make sure that they are H@ S legislation.
we get as many tapes off from scaffold as possible, a lot of developers are putting cherry pickers on site for aerial installation, gas and rain pipe installation,
basically then just jump on and away you go. We have a benefit there because we have IPAF trained operatorsd aswell. you will also require harnesses for cherry picker use.
any tapes that are inaccessible from scaffold, or cherry picker not available we get them from internal access.
regards
martin
