GOLDEN RULES OF QUALITY CONTROL - C M Dordi - 06-11-2022

GOLDEN RULES OF QUALITY CONTROL

Before we deal with any aspects of QC there are eleven golden rules one must remember for successful QC System implementation.

The TOP MOST MAN in the organisation must be convinced that quality must be had.

The great Mr. F. R. McMillen in the foreword to the first edition of his famous Concrete Primer had written "Many who have been interested in the case of better concrete have noted the difficulty of making any real progress until someone in authority has been convinced that good concrete CAN be had, that it SHOULD be had and having been so convinced, has sent out the word that it MUST be had'.

The reporting system of QC Department must be direct to the TOP MAN and not through the person or persons in any manner connected with the Project Management.

Every worker or supervisor in the project team plays a vital role in the QC and hence it is improtant that everyone is aware of the QC System and
inspection procedures.

Quality must be always given preference over Speed and Economy. Good Quality Construction will never be deterrent to project's speed nor will it be uneconomical. In fact time consuming repairs and modification due to poor quality work generally delay the job and cause additional financial impact on the project.

Timely inspection and timely corrective action thereafter, can be the key to successful QC System. Delays in inspection or delays in corrective action and
the main causes of failure of QC System.

Good Quality Construction cannot be carried out by using poor quality materials but it is often possible that poor construction is done using good quality materials.

We must learn from mistakes we make during construction but the mistakes should not be allowed to be repeated under any circumtances .

QC inspector must not only be skillful enough to point out non-conformities but he must also be capable enough to give suggestions to resolve them as well. He should also be able to give suggestions to prevent their future occurrence. The QC Inspector should be observant and watchful. He should not go by hearsay and believe what others have seen. He must believe in what he has inspected or seen personally.

Ignorance, negligence, carelessness and greed lead to construction failures. Hence QC Inspector must have good technical knowledge, must be very watchful, must be very alert and above all must be honest and a person of high integrity.

Totally reject the first concrete member which is found to be unacceptable. Any compromise by way of repairs will encourage the Constrution agency to continue to do poor quality work. If at first instance instructions are given to demolish the defective concrete member then all precautions will be taken to prevent future occurence of unacceptable concrete quality.

Essential Material testing and concrete testing must be carried out at site. It is not possible to control quality of concrete work if the testing laboratory is located far away from site.
