The objective of inspection, broadly speaking, is to provide the owner with a means of assuring quality construction. A good inspection should consist of (1) seeing that the requirements of the specifications are carried out; (2) seeing that good construction practices are used where not specifically covered by the specifications; and (3) recognizing what constitutes good concrete, how to get it, and what might happen if you don't get it. In the field of inspection, an important area is that of quality control. The proper and intelligent application of quality control can be a tremendous aid in establishing and maintaining the type of enlightened inspection that we are attempting to obtain. Quality control includes preliminary investigation of materials, construction inspection and control, and solution of special problems in connection with materials and construction. This discussion is concerned with the second item, construction inspection and control. Control means to make a product or process behave as we want it to behave. Hence, for concrete, quality control means to produce concrete having the properties and characteristics that we want. When specification state the that the concrete compressive strength, as indicated by test cylinders, shall not be less than a specified value, that concrete is clearly inferior. However, suppose the specifications were written so as to permit an occasional low break, and that strength of the concrete would be based on an analysis of a number of tests. Then the variability of concrete strength would be recognized and brought under control. This is what is meant be statistical quality control of concrete. In conclusion, the evidence indicates that inspection is not an easy job. It requires good men, will trained, adequately paid, and properly supported by their employers. It requires good, realistic specifications, properly and justly administered. It requires capable supervision on the part of the contractor. Inspection, properly applied, simultaneously assures that the owner gets the structure he is paying for while the contractor makes a reasonable profit.
