Usually we take samples for laboratory to test or we confirm the quality from the source of materials like the factory, but we still need to make in-situ test for each time we receive materials or even a visual observation. If there is some kind of tools or machines that we should have in the site please mention it.
Contractor must send Material Inspection Request (MIR) of duly approved materials in compliance with Contract Specifications, BOQ and passing Factory Acceptance Test (FAT) with full details at least 24 hours prior to delivery. On the said date, Delivery Notes must be provided specifying quantities. Conduct a visual check if materials to be received are properly handled and in good condition.
There are types of tests or inspections to be considered for materials checking, (1) Visual (2) Measurement-does it meet the requirements or standards? (3) Functional tests -does it do what it is supposed to do? (4) Non-destructive testings. Suppose pipes are to be inspected, commonly cross checking the received materials are being done along with the purchase order/Material approval request and material tests certificate with the details printed/stamped which we call traceability printed on the pipe. Obvious damage like a dent, ovality, pitting, etc can be identified by visual taking into consideration the acceptance criteria. Randomly checking the thickness by the use of a caliper. Another example is a batch of welding electrode, again MTC, traceability and purchase order are to be cross-checked. Packaging shall be intact to avoid absorption of moisture and coating damage. Inspection of different types of materials are all stated in the QCP. I hope this gives you an insight, moallem.
