The evolution of Quality in projects began with Inspection. Inspection involves measuring, examining, testing products, processes and services against specified requirements to determine conformity. The use of inspection has been evident throughout the history of organised production.
Inspection has an important role in modern quality practises. The process of inspection helps to satisfy customers which is one of the primary goals of quality management and also contributes to continuous improvement. Inspection, test and measurement helps in validating the conformity of products and services.
Inspection and testing typically vary, based on the particular scope and needs of construction, this therefore should be customised to individual projects. The type and complexity of the project is dependent on the content of an inspection plan. The inspection plan also is dependent on the special features involved, desired quality level, and the responsibilities of the inspecting organisation that performs the work. To evaluate future acceptance of the work and material products for quality-control purposes inspection may be employed. The inspection process is a part of quality control of a product. The status of inspected items relative to specified requirements is simply established by the inspection. The information derived from inspections and tests, on the other hand, when appropriately evaluated, with conclusions and decisions implemented, can result in the enhancement of the quality of the product or process. The implementation of an adequate plan is achieved by the specialised quality. Such a plan affects the complete project from planning through design and construction to acceptance by the owner. During the construction phase the quality of work is achieved almost entirely by the contractor or producer's quality-control program. This quality-control program combines everyone from management to field supervisor's workers. Quality assurance and quality control should have strong, vigorous support from top management and the active concern and participation of everyone involved in the construction process. In case of quality assurance and quality control programs inspection and testing are a very important part.
