LUL - S1051
Civil Engineering - Bridge Structures
|Publication Date:||1 October 2011|
This Standard applies to Bridge Structure assets owned by LU.
This Standard defines the requirements for assets through the following lifecycle stages:
a) Inception and design
b) Construction, installation, testing and commissioning
d) Analytical assessment
e) Condition assessment and certification
g) Strengthening and Renewal
i) Evidence of compliance
This issue of the standard replaces S1051 A6.
The purpose of this Standard is to define the whole life cycle requirements for Bridge Structure assets. These assets comprise:
a) Rail bridges - This category of structure covers structures owned by LU carrying LU tracks, including:
V) Way beam.
b) Highway bridges - This category of structure covers structures owned by LU carrying public or private road traffic, including:
d) Underground structures - This category of structure covers:
I) Covered Ways;
II) Subsurface tunnels (i.e. cut and cover brick arch tunnel);
e) Earth retaining walls, including gabions;
f) Ancillary structures and components - This category of structure covers:
I) Cable bridges;
II) Pipe bridges;
III) Pipe crossings over / under track;
IV) Signal gantries, these are metal framed structures carrying a signal or signals. Signal posts and signal access ladders and hoops do not form part of the civil asset responsibility;
V) Gantries over railway;
VI) Crash barriers;
VII) Longitudinal Timbers.
In defining requirements specifically applicable to assets, this Standard complements LU Standard 1-050 that defines mandatory requirements generally applicable to all Civil Engineering assets including the Bridge Structure assets.
A supporting Manual of Good Practice G-051 gives guidance and explanation on Bridge Structure assets.
