If it's a railway project they have likely booked several trucks already, doing several deliveries, so one of them having an accident is not likely to matter.

- jen729w 4y agoForgive me if I’m wrong — I have a sibling comment here and am not a construction PM — but no. This comment beautifully demonstrates the point: the disconnect between our industry and the physical world. There are not just concrete trucks just lined up down the road, waiting for a PM to say “okay we’ve got enough, you can stop now”. The amount of concrete is known. It is planned. The 3rd party concrete supplier is given an order well ahead of time. They plan their trucks and drivers. None of this is made up on the day. One of them having an accident matters. This is why IT projects are such a shambles. When we forget something — a change request, say — we just say “oh well, that’s a pity”. Some poor schmuck has a bad afternoon running around making it good and life goes on. We get away with it because it isn’t concrete in a truck.
- maratc 4y agoYou might be overlooking into what I wrote. One truck can deliver about 8 m3 of concrete. If you need 100 m3, that's about 12 deliveries. This can be done if 4 trucks make 3 deliveries each, or if 3 trucks make 4 deliveries each. The supplier has several trucks and while each one needs maintenance rarely, the fleet of them needs maintenance almost daily, so the supplier is likely to either over-provision (have a spare truck), or be able to procure one from his competitor across the street. "One of the trucks having an accident" is already planned in on the supplier level.
