Answered By:

It is correct that one ready mix load of concrete poured at Bond Street Crossrail station in June 2012 was the wrong specification. A non-conformance was identified and the concrete was replaced with the correct approved concrete mix.

In line with the contractual arrangements used by the Crossrail project, the standard practice is that when a contractor raises a non-conformance, and it is accepted, the cost of correction is split 50:50 between the contractor and Crossrail Ltd.
