Satish, I agree with Ralph, but would add, depending
on the configuration of the pipework .... I am
assumming the pipework is above grade. A vertical
flanged sacrificial spool piece could be incorporated
into the piping system. When/if the pipework is over
stressed due to the settlement a new length of flanged
spool piece can be inserted to account for the
settlement.
regards.
