Quality control is the process of quality management. Quality control is achieved by stage-wise as inspections covering the complete process and applied at various stages of operations to minimize the number of non-conformities. Quality control is basically based on the detection concept and is reactive in nature. Quality control in addition to inspection involves the use of the following methods in order to get it off the poor quality products.
Other tools of quality management are
Basic Statistical methods :
Statistics is the science that deals with the collection, classification, analysis and making of inferences from the data or information. Statistics as divided into 2 categories namely
1. Problem Solving techniques :
Any problem in the process of manufacturing is rectified and solved immediately in order to obtain a quality product.
2. Satisfaction in the inspection and testing methods :
By employing modern techniques in testing methods the speed in the inspection can be increased accuracy can be well maintained and the percentage of errors can be minimized to greater extent Tools like testing plan, inspection schedule etc.
Should be mandatorily imposed in the quality management system in order to obtain for better quality product and also speed up inspection.
Golden rules of quality control:
For the successful quality control implementation, the following rules has to be followed strictly:
- The topmost man in the organisation must be convinced about the quality of a particular construction site.
- The reporting system of the quality control department must be connected to the topmost man of the organisation directly and not through any person connected with a project management
- Every worker or supervisor in the project execution team places a critical role in the quality control system. He should be aware of various inspection procedures and training must be provided at the root level.
- Quality must always be given preference over speed and economy. In fact time consuming for repairs and modifications due to poor quality work generally delay the work and cause additional financial impact on the project and timely corrective action can be a key for sucessful quality control system.
- Good quality construction cannot be carried out by using poor quality materials Proper involvement in the construction must learn from the mistakes which has happened previously during the construction and also a keen supervision is required in order and not to repeat the mistakes at any circumstances.
- The quality control inspectors should not only be skilful enough to point out the non-conformance of the project but must also be capable enough to give suggestion to resolve them and prevent their occurrence in the future.
- The quality control inspectors should be observing and watchful and he should never believe in what others have seen but he must believe in what he has inspected and seen personally.
- Ignorance, negligence, carelessness and greed leads to construction failure. The quality control inspectors in addition of having a good technical knowledge must be very alert and should be honest.
- The quality control inspector should totally reject the concrete members or even any other structure which is found to be defective in any part, any compromises of repairs will encourage the construction company to continue to do poor quality work.
- Strict instructions in the beginning of the construction should be given in order to demolish the defective concrete members and only then all precautions will be taken to prevent future occurrence of the unacceptable concrete structures or other construction.
- Essential material testing and concrete testing must be carried out at construction site. It is not possible to control quality of work if the testing lab is located far away from the site and hence it should located in each and every site.
QUALITY ASSURANCE refers to the systematic and planned efforts that are required to provide adequate assurance that a product or service will meet the specified quality requirements.
QUALITY ASSURANCE refers to all of the planned and deliberate efforts required for QUALITY. Give enough assurance that a company will achieve quality criteria A quality audit is an example of quality assurance.
