Most responsible contractors inspect their own work for shortcomings and errors regardless of whether it is subject to scrutiny by others. The builder's own financial interests, his responsibility to his customer, and his obligation to protect the safety of the public- all these considerations argue for careful inspection procedures as a matter of simple routine. For this reason, then, these comments are directed mainly toward the self-scrutinizing type of concrete inspection activity rather than the strictly professional variety, even though it is recognized that the two have very much in common. Let's start with forms. Forms should be checked as they are being placed to see if they are tight, true to line and dimensions, and well tied and braced. They should be cleaned out at the bottom before concrete is placed of all foreign materials- paper, shavings, snuff boxes, etc. The reinforcing steel should be checked also to see if it is the grade specified and sample bars should be cut and tested. They should then be carefully placed using chairs and spacers as necessary. For inspection to be fully effective, the inspector should be on hand to observe carefully the handling and placing of the concrete from start to finish. Every effort should be made to prevent segregation of the concrete on its way into position. Vibration should be done properly by an experienced workman. Depending on the magnitude of the project, the inspector may also make the required test cylinders. Proper inspection always demands careful attention to the important details of joints. They should be properly and adequately made and have a keyway incorporated. A good inspector will also be particularly insistent that the concrete be promptly and properly cured. Cold or hot weather precautions should be taken to insure a first class job of curing. Most builders will agree that a good concrete inspector will be soundly and thoroughly grounded in both the theory and practice of quality concrete construction. It is literally true then that an effective concrete inspector adds in every hour of every work day to the fund of knowledge and information which he brings to his exacting and challenging job.
