2. General
References to standards, guidelines, etc. used in this document will include all referenced standards
and all associated updates and reviews.
The installation shall conform to the standards as defined in the following

BS EN 50173

ISO/IEC 11801

TIA/EIA568

IEE Wiring Regulations, 16th Edition / BS7671: 2001.
Generally the contents of this Specification will take precedence over the above standards unless
otherwise agreed except where this may cause a Health and Safety issue and then generally the
requirements of the IEE Wiring Regulations will take precedence over all.
Should the Contractor require any guidance regarding conflicts between any of the above standards
or the contents of this specification they should consult with the Authority Design Consultant
immediately.
The locations of the data outlets as indicated on the Contract Drawings is indicative to the extent
that where limited deviations from the indicated positioning would be practical to accommodate
specific local conditions this will be acceptable.
For clarity “specific local conditions” would include avoidance of other services, ability to use existing
appropriate containment, constraints imposed by F&E, etc.
Where the Contractor has any concerns or requires guidance on alterations to data outlet
positioning they should consult with the Authority Site Representative.
The Contractor shall be responsible for the removal of all redundant cabling, containment and other
equipment which is being directly replaced by the new installation works including making good all
finishes ready for decoration.
3. Asbestos
The Tender documentation includes details of the most current asbestos surveys for the Schools.
The Contractor will not drill, cut, fix to or in any way damage or alter any of the materials identified
as having asbestos content.
Contract Ref 564 ITT Schedule 2
-2-
Where there is any doubt as to whether a building element contains asbestos the Contractor shall
assume there to be asbestos present and shall contact the Authority Site Representative for
clarification.
In all cases the Contractor will comply with the HSE regulations and guidance on working with
Asbestos.
4. Builders Work
Wherever possible the Contractor will utilise existing cableways.
All new cableways in masonry and concrete will be core cut and located to avoid damaging any
reinforcement or other structural elements.
Cores in masonry walls to be machine drilled and sized to allow the passage of the containment.
Where cables pass through cores the edges of the cores shall be made smooth to avoid damage to
the cables and particular care is to be taken when "pulling in" cables.
Core drilling will be carried out outside School hours at times to be agreed with the Schools.
The contractor shall ensure all Health and Safety requirements and recommendations are fully
adhered to during the coring operations.
All cableways either new or existing in masonry and concrete will be fire stopped on completion and
as a minimum to the same rating as the wall or ceiling with intumescent mortar, putty or other equal
and approved material.
All cableways in timber or timber stud partitions, screens, etc. will be cleanly cut to suit the profile of
the containment and located to avoid damage to structural elements.
The Contractor shall make good all cableways to match the building finishes to leave a smooth joint
with the surrounding finishes.
The Contractor shall make good all existing cableways which are not required for the installation
with appropriate fire stopping to match the fire integrity of the building element and finished to
leave a smooth surface with the surrounding finishes.
Generally the installations shall be surface mounted and the requirement for cutting chases
minimised, however where such builder works are required the Contractor shall make good all
effected finishes and leave the property in a complete state and ready for decoration.
5. Containment - Design
The suggested containment runs and drops are indicated on the Contract Drawings.
The Contractor is invited to review these proposals and amend to reflect the Contractor’s tender and
the blend of containment types being proposed.
Contract Ref 564 ITT Schedule 2
-3-
The Contractor shall include in his Tender a brief summary of the Containment types being proposed
for each of the main areas within the Schools in a table to be submitted with the Tender.
The successful Contractor shall be required to Provide Working Drawings (in AutoCAD format or 3
paper copies) showing the detail of the Containment routes being proposed, the sizing of the
Containment and the proposals to utilise existing, all for agreement prior to commencing the works.
The Contractor is encouraged to use existing Containment where it is appropriately positioned, sized
and in Serviceable Condition. Where existing Containment is utilised this will have been deemed to
have been adopted by the Contractor for the purposes of post contract defects liabilities.
It is fully expected that during the works the Contractor may wish to amend the Containment design
proposals as the local anomalies and constraints become evident. This will generally be acceptable
where adherence to the design criteria is maintained and will be subject to the agreement of the
Authority Site Representative.
For clarity the tender cost for the containment will be provided on a fixed cost basis and any
subsequent deviation from the design post tender will be at the Contractor’s risk except where the
amendment is the result of an Authority act or omission and constitutes a contractual change.
The general requirement of the Containment design is that:
Containment shall be sized to ensure no more than 80% capacity.

