For the reinstatement of natural stone modular surfaces, the following applies:
Natural stone modules within the area to be excavated must be removed and stored by the undertaker for re-use.
Modules must be reinstated in accordance with A12.
Where the authority has a policy that seeks to re-use existing modules that are damaged, the parts or fragments must be removed and stored by the undertaker for re-use. The undertaker must notify the authority and the method of reinstatement for these materials must be agreed, including any limitation on the size of the fragments.
Where it has been agreed that damaged modules are to be re-used as part of the permanent reinstatement, the surface profile at the end of the guarantee period is not required to be superior to that existing at the time of excavation.
The undertaker must use best endeavours to match existing profiles and meet the tolerances specified in S2, subject to the limitations outlined in A12.
