The construction industry has been practicing to achieve the quality for many years, and dependant on the cost of economy which is drastically changing over period.The cost could potentially be reduced if the construction industry were to embrace the concept of quality assurance that has been used with great success by many other sectors of the economy. For achieving better quality of work at a minor cost compared with the total cost of the project, proper Quality Control process need to be adopted for best results. For achieving QA at the site it is necessary to comply the construction specification standards exactly.This can be achieved with a properly organized well equipped field laboratory at the site and centrally located at office. A Quality Assurance System to have any credibility must comply with ISO 9000 and ISO 14000. The construction specification in similar project to be executed in future should be modified based on lessons learnt during quality control exercised on previous projects. Quality of work largely depends upon the quality of materials to be used and workmanship.The relevant specification in respect of materials/ workmanship given in various IS codes be strictly adhered to for accomplishment of QA/QC. QC should be exercised at different levels such as pre-construction, during construction and postconstruction.
