Looking for some advice (again).
On a massive new site we are tendering (past the first stage - next is interview with agent and 7 directors!) there is a small amount of marble that will need regular monthly buffing. The additional notes/requests we have just received want us to include purchasing a "small maneuverable machine suitable for monthly buffing of marble areas (circa 1000 sq feet) - machine should be expected to have operational life of approx 3 years. Please note storage space is of a premium."
Any suggestions? - the areas concerned are a couple of lobbies and mainly long straight corridors.
