scope:
This Specification applies to all work on London Underground that contains elements that will form part of, or interface with, the deep tube tunnel and shaft assets. The definition of which assets form part of the deep tube tunnel catalogue are provided in Section of London Underground Category 1 Standard 1-055, Deep Tube Tunnels and Shafts and includes the following:
a) Running tunnels
b) Cross passages between running tunnels
c) Step plate junctions
d) Crossover tunnels
e) Depot approach tunnels (e.g. London Road)
f) Overrun tunnels
g) Siding tunnels
h) Platform tunnels
j) Concourse tunnels
k) Station passageway tunnels
l) Tunnel headwalls
m) Tunnel ringwalls
n) Tunnel openings and junctions
o) Inclined shafts (e.g. escalator shafts)
p) Vertical shafts (e.g. ventilation, access, service, lift and substation shafts)
q) Cable shafts
r) Pump shafts
s) Disused tunnels
t) Disused shafts
u) Other tunnels and shafts constructed by mining methods
Purpose
The purpose of this Specification is to specify the materials and workmanship (M&W) to be used for deep tube tunnels and shafts on London Underground. The format of this M&W specification follows that of the British Tunnelling Society and Institution of Civil Engineers Specification for Tunnelling Third Edition 2010, highlighting only any differences, clarifications or omissions that are necessary when applying this specification to works on London Underground. The aim of this document is to avoid the need for bespoke specifications to be written for each project relating to London Underground deep tube tunnels and shafts and to assist in the development of generic products and methodologies that can be applied to provide a consistent approach to the construction and maintenance of these structures.
Throughout the remainder of this document the term "BTS Specification" shall be taken refer to the British Tunnelling Society and Institution of Civil Engineers Specification for Tunnelling Third Edition 2010.
