To establish a system for ensuring that
Incoming items meet the specified contract and Quality requirements. Identify
material from receipt through installation, Maintain historical records of the
materials, and be able to trace assemblies and selected subassemblies through
identification and marking.
Activities such as handling, storage,
preservation, of products, systems, components, or installation material on
receipt at company sites shall follow this procedure.
2.0 SCOPE
This procedure applies to all systems,
components, and/or installation materials purchased, and/or used by the company
for fabrication and/or installation within the project.
3.0 DEFINITIONS
This procedure
uses definitions in the front of the Quality Plan and ISO 9001 Quality Management
and Quality Assurance Vocabulary.
4.0 General
It is
the responsibility of Quality Department to ensure the identification and
traceability of the item delivered for construction. System, Components and
Installation Materials, System, equipment, component or parts shall be
traceable to manufacturers’ serial number.
Responsibility
Store-Keeper: The store keeper is responsible for receiving
materials and ensure the quantity of the materials delivered comply with the
delivery note and Stored in Proper Manner.
QC Inspector: The QC Inspector is responsible for
verifying the findings of the store keeper; he is also responsible for final
approval of materials/equipment during internal inspection and ensure that the
delivered material comply with the approved material submittal.
Site Engineer: For major item, the site engineer will
participate in receiving material and inspection.
QA/QC Engineer: The QA/QC Engineer is responsible for
maintaining the database, which provides necessary identification and
traceability of Materials.
4.2 Material Receipt
The store keeper will receive and
verify all materials/equipment against the Purchase Order, count and check for
damage, and if in order and acceptable, complete and sign the delivery note.
Store keeper
notifies the Quality Team that materials/equipment have arrived and arranges
for Inspection the findings should be recorded on the Receiving Inspection
Report Form.
The INELT Quality Team will check
and verify all materials received and subject them to Goods Receiving
inspection. This check will be a physical inspection and it will be noted with
the appropriate corresponding documents and MRIR is generated.
This physical inspection will
ensure that we have received the correct product that the product is in
compliance with the materials description such as: Field tags, stamps, and any
marking of identity.
Site QC Inspector will check the
objective evidence as provided by a Supplier to determine that adequate quality
verification was exercised, for example, review inspection and test reports, MAS's,
etc....
The QC Inspector will examine all
material for conformity to the Purchase Order and drawings. This examination
should cover but not be limited to the following: Dimensions, marking and
condition. Name Plate. Quantity and Quality of Product. QC inspector also
verifies that the materials delivered are as per material submittal and
approval. Uncertified materials will be kept in quarantine and the MRIR will be
promptly and accurately filled out.
4.3 Materials Storage and preservation
Tags/labels affixed to the outer
box or storage rack identify the contents and physical characteristics of store
items.
The store-keeper and the QC
personnel shall perform regular monitoring on the material stored to verify
their condition.
INELT will store all materials
and equipment in such a way as to protect them from damage, deterioration,
contamination and loss of identification. Main Contractor will make special
provision for sensitive items such as chemical materials, electronics
equipment, paints, etc.
INELT will document receipt of
materials with their precise location within the lay down area and will ensure
that materials of different types, grades and specifications are segregated.
Materials / equipment requiring special
storage conditions shall be stored in accordance with manufacturer's
instruction.
Heat sensitive items shall be
stored under temperature control environment. Materials provided with
preservatives during storage shall be verified for proper Packaging and
storage.
The QA/QC Engineer, based on the
input from the equipment supplier, will prepare and maintain a list of all
equipment subject to preservation, including frequency and the type of
preservation to be used. Condition of equipment and material in storage will be
checked periodically to prevent deterioration and identify non-conforming
conditions
The Main Contractor shall provide
adequate storage area (Laydown Area) for storing materials and equipment. The
Main Contractor shall also provide adequate security for all stored materials
within the construction site and laydown areas. Facilities such as electrical
power shall also be provided for the internal storage. A well-constructed sun
shade shall be provided as well by the Main Contractor for externally stored
materials.
4.4 Material release/issue
INELT will use Material
Requisition to release materials or items from the Laydown/storage area for
fabrication/construction operations. These will be submitted for review and
approval by the responsible personnel prior to the subject material being
issued from INELT lay down Area or store.
INELT will ensure that the
material/equipment is correct for the intended application, that is full and
correctly documented and identified and that its issue is recorded.
INELT will then issue the
material/item ensuring that no damage or loss of identification is incurred
during any loading, off-loading, slinging or other handling operation.
In the case of materials issued
and loaded for dispatch to a sub-contractor, INELT will ensure that
identification is intact prior to dispatch.
4.5
Handling
Selected employees are
instructed, as required, in proper methods of material handling before any
actual handling of material occurs.
Site
Supervisors/Foremen ensure proper handling, storage
and preservation of materials/equipment issued at work sites. Quality personnel
monitor the condition of storage and preservation of materials on site.
To prevent damage during material
handling the following devices may be used: manual or mechanical lifting
equipment, Boom Trucks or Cranes for heavy equipment.
4.6
Packaging and Delivery
Whenever materials are
transported from sites, the site supervisor ensures proper packaging and
delivery.
The site supervisor also verifies
the contents before sealing the package and prepares a Material Transmittal.
4.7 SUPPORTING DOCUMENTATION
Prior
to final acceptance of material/equipment, the QC Inspector will
verify that supporting documentation has
been received and accepted, and the number and specifications from the material
is identical to that identified on the Material Catalogue and Test Reports.
MTR's should be verified by the
QC Inspector for accuracy of Heat Numbers or Identification numbers, his
verification should cover chemical composition, physical and mechanical
properties. Approved MTR's should be signed and dated by the QC Inspector and
filed in the Quality Records.
Approved MTR's must be annotated
with Contract No., P.O. No., P.O. Item No., and Project Name.
4.8 POSITIVE RECALL
Products which are not fully
inspected may be released for construction by the QC Inspector, with the
Project Manager and Proponent’s concurrence, under the condition that they can
be recalled if the complementary Inspection shows that the items do not conform
to the specified requirements.
The use of this procedure will be
restricted to material/components for which quality documentation from a
supplier is not available for review and acceptance by QC Inspector. The
supplier will be contacted to confirm that all required inspections/tests have
been carried out, accepted and available for submission and review. The
affected item will be released from the segregated hold area but hold tags
attached will remain until final disposition of the nonconformity.
If the QC Inspector decides to release the material/component on a recall basis, he should inform the Site Project Manager in writing.
The QC Inspector records the
identification of the material components to be released, and if necessary
makes additional identification either directly on the material/components or
on a Tag in such a way that it is possible to trace and to identify, if they
should have to be recalled. If the complementary inspection shows that the
material/components do not conform to the specified requirements, the QC
Inspector will recall the material/component and inform the Project Manager.
The materials/components are
brought back to the segregated hold area and processed. Main Contractor will
provide a segregated area for storing materials found nonconforming to the
project requirements before returning to the supplier.
5.0 Material storage procedure for various electrical components:
·
Storage area should be clearly
defined.
·
Separate areas should be used for
different items (For Ease of identification)
·
Certain materials and substances
should be segregated during storage.
·
Areas should be kept Clean and
should be routinely inspected.
·
Appropriate warning signs should
be displayed where necessary( E.g where flammable materials are stored)
5.1 Fiber Optic Cable
Fiber Optic Cable handling and placing
·
Cable should never be bent below its
minimum bending radius. Doing so can result in bending losses and/or breaks in
the cable's fibers.
·
The minimum bending radius of a fiber cable
under load is 20 × D, where D is the diameter of cable; the minimum bending
radius of a fiber cable under no load is 15 × D.
·
The cable should never be loaded beyond its
maximum tensile strength. Exceeding the cable's placing tension provided in the
Cable Data Sheet/Specification, can alter cable and fiber performance and
shorten its service lifetime.
·
Broken fiber ends created during
termination and splicing can be dangerous. These ends are extremely sharp and
can easily penetrate the skin. They invariably break off and are very hard to
find and remove.
·
Be careful while handling the fibers.
Dispose of all scraps safely and properly. Do not eat or drink near the
installation area.
5.2 Fire Alarm
- Materials
shall be offloaded and stored in the designated area as per the
manufactures instruction.
- Storage area shall be barricaded
and signed off to prevent unauthorized entry of personnel or moving
equipment.
- Materials shall be protected from
direct sunlight as per the manufacturer’s recommendations.
5.3. CCTV POLE

discussed in pre-start briefing and followed.
5.4 GI Cable Tray and Trunking:
A.
Handling.
·
Trays/Trunking shall be packed in bundles
using adequate banding and balanced at the center.
· It is recommended
that where possible non-metallic banding is used in order to avoid rust stains
forming on galvanize products.
· Where products of
three meter lengths or above are packed in bundles, they shall be supported
with a minimum of three timber bearers which provide sufficient clearance to
accommodate the forks of a forklift truck. Bearers shall be spaced evenly along
the length of the bundle.
· Where shorter
length products are packed in bundles, they shall be supported with a Minimum
of two timber bearers which provide sufficient clearance to accommodate the
fork of the trolley. Bearers shall be spaced
evenly along the length
B. Loading and Off-Loading recommendations.
· Site deliveries should preferably only be made where
suitable mechanical handling equipment is available on site.
· The delivered material must be treated with care. Lifting
must only be carried out from the sides and the forklift truck tines must pass
below a complete bundle, or manually lifted if delivered in singles.
· The tensioned
banding used for securing bundles of equipment during transport is not suitable
for lifting purposes. When cutting this banding appropriate eye Protection must
be worn to avoid injury.
·
Sheared steel (particularly pre-galvanized)
does have relatively sharp edges and protective gloves must be worn during
handling.
C. Storage
In order to store Cable Tray Systems and
Cable Trunking Systems safely and maintaining them in their delivered
condition, the following guidelines should be considered:-
·
Products which are either Hot Dip Galvanized
(HDG) after manufacture or non-metallic can be stored outside without cover
(excluding boxed items). When stored outside products should be stacked in a
method that ensures adequate drainage.
·
However outside storage is not recommended for
galvanized products due to wet storage stain.
·
Ideally, all metallic products should be
stored undercover in a dry, unheated environment and be loosely stacked off the
ground to ensure adequate ventilation.
·
It
is important that products that have different finishes are kept apart.
Products Pre Galvanized (PG) before manufacture should always be protected and
stored in a well ventilated and dry location, and well stacked.
·
Any
components packaged in degradable bags, boxes, cartons etc. should always be
stored in a well-ventilated and dry location.

Cables:
GUIDANCE ON HANDLING, STORING &
INSTALLING POWER CABLES
HANDLING:
Damage to cables can occur due to incorrect
handling of drums and cables leading to the breakdown of the drum flanges. In
exceptional cases, movement of the drum barrel may also take place. Once this
breakdown of the drum occurs, the cable is immediately exposed to damage.
For guidance on handling, please refer to
the sketches and notes contained in this booklet, which should be followed
closely. We have no objection to the use of fork-lift trucks provided that care
is exercised not to damage, or remove, the protective battens when pushing the
forks under the drum flanges. Unloading can also be safely accomplished by
means of ramps and winches.
Under no circumstances should a drum be rolled
off a vehicle on to a „cushion of‟ sand, tarpaulin, etc. This action could crumple the
flanges and barrel of the drum, driving splinters and/or nails into the cable
STORAGE:
If
at any time the drums of cables are required to be stored for reasonably long
periods, e.g. prior to shipment or installation, the following points should be
noted.
1) The site for storage of drums should be
well drained, hard packed soil, or preferably a concrete surface, which will
not allow the drums to sink and so give rise to damage due to the extreme
difficulty in moving drums when they are sunk into the ground.
2) All drums should be stored with the
battens intact, and in such a manner as to leave sufficient space between them
for air circulation. Check and tighten tie bolts on the drums at regular
intervals.
3) Tier stacking of drums is not
recommended. Under no circumstances must the drums be stored „on the flat‟ i.e., with flanges horizontal.
4)
All drums, during installation (i.e. when the battens have been removed),
should be „scotched‟
so that there is no danger of the flanges of drums coming into accidental
contact with unprotected cable on other drums. The cables should not be left
unprotected.
5) Cables should be protected from direct
rays of the sun by leaving the battens on or covering the cables with thick
black polythene sheet.
IMPORTANT: Cable ends must be sealed with end
caps during storage and transportation.
5.6 DB and Feeder Pillar:
Storage / Protection: DB, Feeder
Pillar and Accessories shall be unloaded with care to avoid any damages. If
they are shipped in packs or pallets, each pack of pallet shall be lifted
individually with suitable lifting equipment. Every precaution shall be taken
to preserve their cleanliness before installation. Store in accordance with
manufacturer’s instructions, properly protected from construction activities
and weather conditions.
