The Works consist in constructing a Tunnel of the size necessary for a single line of Railway and lining the same with Brickwork as shewn on Drawing No. 7.
The contractor will be at liberty to open cut the ground at each end of the tunnel to the extent of not more than twelve yards from the front for the purpose of building the end lengths. The width of the Excavation is on no account to be greater than the outside of the Masonry or Brickwork and the sides shall be well supported and kept open by suitable timbering until the Masonry or Brickwork is completed. The open space is then to be filled up to the original surface by layers of clay not more than One foot in thickness, each of which is to be well and carefully punned <ref group="note">"Punned" is similar to "puddled", clay that has been rammed hard to make it water tight.</ref> before laying on the succeeding layer. When completely filled, the surface to be neatly trimmed to the surface and inclination of the Excavations and to be properly turfed or soiled and sown with seeds.
The Work is then to be continued from the open ends by mining in the usual way. The Excavation obtained from the Tunnel is to be tipped into the Embankment or run to spoil at the ends of the Tunnel and dressed and soiled as directed by the Engineer.
Should any portion of the Tunnel in the opinion of the Engineer not require to be bricked the same shall be excavated as nearly as possible to the net size shewn on the Drawings and no portion of the Tunnel will be permitted to be of less dimensions than shown on the drawings at anpoint but no allowance will be made for any Excavations in excess of the drawings. If on the completion of these portions of the Tunnel, the Engineer should on examination be of opinion that any pieces of rock have been so far loosened by the blasting and other mining operations as to be in danger of falling out, the Contractor shall remove such pieces of rock on being required to do so without any additional payment therefor.
