material certificates are included with the consignment and this information shall be recorded on
the Material Receiving Reports.

6.2.2. For materials with full traceability or any other special requirements, or if required by the
applicable Inspection and Test Plan, QC inspectors will follow the material checks and carry out
inspection including checks of identification marks and traceability.

6.2.3. Items or bundles of items that are individually tagged and identified shall be stored in the
warehouse such as to ensure easy recognition; Material Controller(s) and Storekeeper(s) shall
ensure that identification marks and tags do not get erased or detached.

6.3 Issue of Permanent Materials

6.3.1 All permanent materials supplied for the project shall fulfill the requirements
specified by the contract specifications. Issue of permanent materials and
definition of WACOM.s personnel involved and their activities/ interrelations.

6.3.2 The control of non conforming materials is defined in procedure. Personnel

whose activities are defined there in shall refer to paragraph 6.4 to 6.8 for
certification and traceability requirements.

6.3.3 During construction/installation and until mechanical completion, all personnel

involved shall refer to paragraphs 6.4 to 6.8 for the definition of the traceability
requirements during processing materials including installation.

6.4 Traceability of Civil Materials

6.4.1. Traceability and approval of civil materials shall be in accordance with

specifications and QC documentation.

6.4.2. Cement shall be checked as acceptable (manufacturer’s certificate) prior to

loading into the silo, only conformant cement shall be used.
 6.4.3. Aggregates are received into a 'Bulk' storage area and sample tests taken. If
these are within specification they are then moved to the 'Feed' storage or Batch
Plant.

6.4.4. All water shall be tested before initial use both at source and storage supply.
Testing thereafter shall be in accordance with specifications. Mix water shall
conform to requirements in “Ready-Mixed Portland Cement Concrete”.

6.4.5. Additives are received with a manufacturers certificate of analysis. If stored for a
period exceeding the “use by” date specified by the manufacturer then they are
tested prior to use.

6.4.6. Reinforcement (Rebar): all rebar is supplied with a manufacturer’s mill certificate.
Coated rebar is supplied with a certificate from the coating manufacturer. Both
sets of certificates shall be checked against the tags on the bundle of bar during
receiving inspection.

6.5 Inspection, Measuring and Test Equipment Calibration

Equipment calibration traceability requirements are defined in Wacom calibration procedure

6.6 Certification and Traceability Requirements of Material

The following material traceability system will be used for the Project job site. For all
bulk material, certification and traceability requirements shall be in accordance with
contractual requirements.

6.7 Material requiring Normal Traceability.

Receiving inspection (Warehouse Inspection) of material

a) Upon receival of materials the Material Controller or his designee shall verify receipt of the QC
Data Book, type of Material Certificate and color code as applicable.
b) Color coding shall be along the longitudinal axis not on the circumference. Color coding system
for material is defined in the CONTRACTOR’s specification: “Identification of Material”.
Fabrication and installation traceability of material

a) After issuing the materials to the Construction team, the Construction team shall be responsible
for the material control. QC Inspectors and Supervisor shall check/monitor the team's quality
control activities (incl. traceability control). Materials shall be checked against the material
isometric drawings and materials lists.
b) Color coding in accordance with the specification shall be maintained during all stages of
fabrication. When cutting material, the cut material shall be identified by color coding or marking
