The big problem here is that without the actual hands on experience of pumping, spreading, leveling and all that that entails is not for the faint heart, if only one large or small component fails or is not in place then you are left in total limbo, with a full truck of wet concrete with no where to go?
I have been on sites when someone forgot to go and get the petrol to run the vibrators, we had four or five concrete trucks lined up in the street, a tower crane waiting, the concrete crew on stand down, need I say more?
Even worse I recall on a November night, as I recall was later than 1800 hrs. on a Multi-Million £ Government site in Milton Keynes with a critical Concrete pour over running on time, the Concrete plant had shut down we had exhausted its entire stock of Cement, with five or more Concrete trucks stacked, all perilously close to being out of their tachograph times when the Concrete pumps engine water pump failed, the pump overheated and the engine cut out. No spare pump, no where to go. pour water over the pump engine, cool it down get it started and put in an emergency stop end to finish the pour of a suspended floor in a safe position.
NOT A GOOD DAY!!
