hi there
the biggest issue will be tupe
you may find that the cleaners have actually been on the site for years, only the cleaning company changes.
why?? cost saving all the time, a retender exercise, reduces the costs for the client in real time, and therefore reduce visible profit line for the cleaning company. eventually the cleaning company will then xut its overheads on the contract and may sometimes jeopardise quality of service by doing that.
the other point is that during term time the clean will be different to that of the holidays, therefore you need to factor that into the equation.
we did a infant and junior school flood restoration last year, actually ONE week after the new school year started. the carpets in the school were cleaner when we finished our job, didnt say much for the NORMAL cleaning specification.
