Edges and adjoining features
If the property has historic walls or paving that will remain, specify how the new surface should meet those features.
Why it matters for your tarmac surfacing: Show each boundary and adjoining feature so restraints, protection and junction details can be priced clearly. For tarmac surfacing, it can affect excavation, compaction, course depths, drainage, edge support and the handover programme.
Useful photograph: all borders, walls, planting, gates, trees and surface junctions.
