Highway England state none of their ASC (contracts) has a schedule of defined costs.
8/04/2019 A FoIA request @ WDTK received the reply:
As none of the ASCs contain schedules of rates, and Highways England considers that the lack of transparency applies equally to above threshold claims (i.e. those above £10,000) claims as well as claims below threshold it was considered that a review covering all areas was required.
This, like much emanating from the Authority, is simply untrue. The evidence is here.
