(d) In any case in which any house or building shall have been underpinned or strengthened under the powers of this section the appropriate authority may, from time to time after the completion of such underpinning or strengthening, and during the execution of the work in connection with which such underpinning or strengthening was done, or within five years after the opening for traffic of that work, enter upon and survey such house or building and, after complying with the foregoing provisions of this section, do such further underpinning or strengthening as they may deem necessary or expedient;

(e) The appropriate authority shall be liable to compensate the owner, lessee and occupier of every such house or building for any loss or damage which may result to them by reason of the exercise of the powers of this section;

(f) Nothing in this section nor any dealing with any property under this section shall relieve the appropriate authority from the liability to compensate under section 10(2) of the Act of 1965, as applied by this Act, or under any other enactment in respect of loss or damage arising from the execution of any works, other than works of underpinning or strengthening authorised by this section;
