The Client had expected that the gasket materials along the pipework would be either completely asbestos containing or not so the survey scope required that gaskets only be representatively sampled, rather than in their entirety. However, of the 100 gaskets sampled, 50% contained asbestos in a random distribution and it was not limited to single specific pipe runs. This presented a challenge for the project in that it was envisaged that sampling and testing requirements would not be so extensive and Client did not want to cause a delay to the project programme.
