Posted By Jeffrey Watt Liam No, but... I believe the designers of some of the first trains to be used in the channel tunnel got stopped/sued/prosecuted under Section 6 of the HASAWA due to the braking system being inadequate. Not very detailed,sorry, trying to remember a lecture from 6 years ago. Jeff

Posted By Jerry Lucey Hi John, Have you spoken to the Quantity Surveyor on the project, as they may be in a position to help i.e. compromise or claw back the difference in an area which is not safety critical. I have found that a Client may object where such a safety system is not considered as part of the initial design but proposed at a later stage in a project, where there is a variation in the original cost, however he may be happy enough to go along with the above arrangement. Failing this I would do what the previous post suggests and present the Client with the Design Risk Assessment, explaining the legal requirement with regard to reasonably practicable.
