If the current driveway has uneven sections, ask the survey to establish whether the base needs repair or replacement.
Why it matters for your tarmac surfacing: Photograph defects and previous patches so the retained layers and any rebuilding can be discussed separately. For tarmac surfacing, it can affect excavation, compaction, course depths, drainage, edge support and the handover programme.
Useful photograph: the whole existing surface plus close views of cracks, movement or patches.
