of the premises to “provide an installation specification
in accordance with BS EN 50174-1 for telecommunications equipment
and telecommunications cabling.”
BS EN 50174-1:2009, clause 5.1.1, requires that “the installation
specification prepared by the premises owner or an appointed representative
shall be agreed before the installation commences.”
BS EN 50174-1:2009, clause 4.1.3.1.1, requires that “the
scope of work shall detail requirements for … any building
work required on each pathway” and “additional surveys
to be undertaken to supplement information in the scope of work.”
BS EN 50174-1:2009, clause 4.1.3.2.2, recommends that “the

BS 6701:2004,
clause 5.1.2, states that it is the responsibility of the owner
of the premises to “provide an installation specification
in accordance with BS EN 50174-1 for telecommunications equipment
and telecommunications cabling.”
BS EN 50174-1:2009, clause 5.1.1, requires that “the installation
specification prepared by the premises owner or an appointed representative
shall be agreed before the installation commences.”
BS EN 50174-1:2009, clause 4.1.3.1.1, requires that “the
scope of work shall detail requirements for … accommodation
of the terminating devices for external and internal cables at building
entrance facilities” and “additional surveys to be undertaken
to supplement information in the scope of work.”
BS EN 50174-1:2009, clause 4.1.3.2.2, recommends that “the
scope of work should contain site plans that are marked up to show
the works required.”
BS 6701:2004, clauses 4.1.4.2 and 4.4.2, state that it is the responsibility
of the installer to ensure that "telecommunications cables
intended for use external to buildings and which contain flammable
material (e.g. polyethylene sheaths, petroleum gel) shall be either:
terminated,
inside the building, within 2 m of the point of internal penetration
of the
floor/ceiling/wall
fire barrier of the building; or
installed
in trunking or conduit that has a fire resistance agreed with local
fire authorities …:"
This requirement has been modified in BS EN 50174-1:2009, clause
4.2.2.1, and EN 50174-2:2009, clause 4.1.8.2, to read “Information
technology cables that do not comply with EN 60332-1-2 shall either
be:
terminated
inside the building, within 2 m (or an alternative distance if specified
by local
regulations)
of the point of internal penetration of the fire barrier (e.g. floor/ceiling/wall);
or
installed
within trunking or conduit that is considered as fire barrier in
accordance with local fire
regulations.”
BS EN 50174-3:2003, clause 5.9.7, contains requirements and recommendations
for the treatment of cables and their earthing. however, these are
replaced in the UK by the requirements of
BS EN 50174-1:2009, clause 4.2.2.1, and EN 50174-2:2009.
BS EN 50174-3:2003, clause 5.5 and 5.9.6, state that "cabling
management systems at the entrance into a building shall be sealed
to prevent the ingress of dust, water, animals, gas, etc."
BS EN 50174-3:2003, clause 5.9.6, states that "incoming cabling
management systems shall ensure continuity of cabling, and be connected
directly by the shortest possible distance to the equipment room
of campus or building, without exceeding constraints (e.g. bending
radius or ducts of constant cross sectional area)."
BS EN 50174-3:2003, clause 5.9.6, also provides recommendations
for the location and configuration of ducts at the building entrance
facility.
BS EN 50174-3:2003, clause 5.9.6, states that the segregation of
mains power and information technology/telecommunications shall
be, by implicit reference, in accordance with BS EN 50174-2:2001,
clause 6.5, and BS EN 50174:2003, clause 5.9. In the UK the requirements
of BS 6701:2004, clauses 4.4.4.2 and 4.4.4.3 also apply.
BS EN 50174-3:2003, clause 5.9.6, states that "metal pipes
(e.g. for water, gas, heating) and cables should enter the building
at the same place" and "metal sheets, screens, metal pipes
and connections of these parts shall be bonded and connected to
the main equipotential bonding of the building with low impedance
conductors" and external reference is made to BS EN 50310.
BS EN 50174-1:2009, clause 4.1.3.2.2, recommends that “the
scope of work should contain site plans that are marked up to show
the works required.”

to contain modified requirements concerning treatment of cables
in entrance facilities as follows:
“Information technology cables that do not comply with the
minimum recommended performance requirements of EN 60332-1-2 shall
either be:
terminated
inside the building, within 2 m (or an alternative distance if
specified by local
regulations)
of the point of internal penetration of the external fire barrier
(e.g. floor/ceiling/wall);
or
installed
within trunking or conduit that is considered as external fire
barrier in accordance with
local
fire regulations.”
NOTE: this also applies where the cable has to pass through a
space between two external fire barriers within a building.
BS EN 50174-3:2011 is also expected to contain the above text.
BS EN 50174-1:2009 Amendment 1 (2010) and BS EN 50174-2:2009
Amendment 1 (2010) are expected to redefine “mains power”
cabling as “power supply” cabling - with a definition
that excludes PoE applications of information technology cabling.

The
risk element explained |
|
BS
6701:2004 and EN 50174-1:2009 require the production of an installation specification that includes a scope of work.
Failure of the scope of work to accurately specify
the cables to be installed in each pathway represents a self-evident
risk in terms of potential for confused instructions, delays and
associated cost. This risk is based on potential for:
incorrect
routing in terms of connectivity;
physical
incompatibility (loading, bend radius, cross-sectional area etc);
environmental
incompatibility of cables and protection provided by pathway systems. |

and telecommunications cabling.”
BS EN 50174-1:2009, clause 5.1.1, requires that “The installation specification prepared by the premises owner or an appointed representative

The
risk element explained |

BS
6701:2004 and EN 50174-1:2009 require the production of an installation specification that includes a scope of work.
Failure of the scope of work to accurately specify the layout of
cabinets/frames/racks and the closures (both within cabinets/frames/racks
and in dispersed around the premises) represents a serious risk
to the operability, maintainability and repairability of the infrastructure.
Correction of errors is generally impossible without total re-work
of the installation.
No installation should ever be undertaken
without a formal layout drawing or instruction for each closure/cabinet/frame/rack. |
