hi there
99% of builders cleans will be tendered works, ie build clean, reclean and sparkle clean, per plot pricing.
you will have to price all the work from a set of drawings at the outset, they are then awarded by the quantity surveyor.
you will need to file all your method statements, risk assessments, coshh data and risk assessments, cscs cards etc.
site managers call of the work as and when required, a lot of plots are build cleaned on a friday, and then recleaned the following friday, wth sparklecleans beign completed the day before the client moves in.
a lot of sparkles done at the end of the month. rushes at quarter ends and the end of june and dec.
i would expect that when the sitesstart back up in time, then there will most likely be even more emphasis on the end of june and december build cycles.
also remeber that the work is cis deductable.
potentially very hard work.
regards
martin
