To ensure clarity and agreement on the extent of the work to be undertaken, we would like to confirm our understanding of the scope of the neighbouring buildings survey by reference to the plan (attached below). The extent of surveys are to the outdoor property, external and internal building of Building No.171, 171/1, 176/63-85 and Building No.224/2 which are located not exceeding 5 metres from the boundary of the proposed contract site. However, internal building survey depends on the owner’s permission with the Contractor’s co-operation.
