TUNNELS. A "Tunnel" shall be defined as a subterranean excavation, lined or unlined, which because of its length necessitates an employee or employees working underground for a distance of ten feet or more. On all work classified as "Tunnel" the tunnel classification and rates shall apply to the entire length of the tunnel, from portal to portal. A tunnel whose horizontal grade is over Thirty Percent (30%) and less than Sixty Percent (60%) shall be defined as a "Raise". A tunnel whose horizontal grade is greater than Sixty Percent (60%), and whose depth is more than twice its largest horizontal dimension, shall be defined as a "Shaft. ' The above definitions of work shall apply also to the work of timbering and lining of tunnels (raises and shafts) as described above.

TUNNELS. When a Technical Engineer is working in a tunnel, they shall receive $3.00 over their regular rate.
TUNNELS. While the network is based on IP/MPLS, the equipment shall also support encapsulation in GRE and IP, providing more flexibility to expand the network through third party networks if required.
TUNNELS. All existing tunnels are to BG rolling stock standard clearance. Total number of tunnels: 57 Nos.
TUNNELS. Based on information from the existing Feasibility Study, dated 2008, the total length of tunnels is 7430m. Due to envisaged areas of difficult tunnelling, the Consultant shall plan the new boreholes at a maximum nominal spacing of 50m. This means approximately 150 new boreholes are required to inform the design. It is likely that some of these boreholes will be inclined or horizontal. Out of the 150 anticipated boreholes, the Consultant shall execute 75 boreholes in Phase 1 and another 75 in Phase
