The success of concrete construction projects is dependent upon the following: a proper plan accompanied by effectual specifications; a design that takes into account material, labor, and equipment availability; a complete understanding by the contractor of the job's requirements as dictated by the specifications; and a thorough inspection procedure. Let us assume that the job has been properly designed, that all materials, including formwork, are as specified, and that the work will be performed by competent personnel. What, then, makes the difference between a good job and a bad job? Why do we do to obtain consistently good quality? Good quality control will eliminate shoddy work. Careful adherence to good job practices should be observed in the following seven concrete construction functions: handling, placing, consolidation, finishing, protection, curing, and inspection. Quite possibly the most important thing to remember when handling concrete, by whatever means, is that the material is being manufactured right on the jobsite. This is the major difference between concrete placed on site and other prepared construction materials such as steel, timber, glass, tile, and brick. It is essential that the concrete that comes out of the mixer is exactly what is wanted in the finished structure. To meet this requirement, it must first be determined what the concrete is expected to do. Proper handling methods require a knowledge of the use to which the concrete is going to be put. Any method that will take a good concrete mix, move it into the forms, and not unmix or change the formula is a satisfactory means of placing concrete. Placing concrete means more than just dumping the material into forms, and it involves a great deals more than just shoving the concrete around with a vibrator. The function of the vibrator is to density the mix. Proper temperature must be maintained in the mix during and after placing. Any change in slump may require a change in placing method. Reshoring is a very important part of the concrete operation and knowledge of its requirements is mandatory. You must know the number of floors of reshoring necessary in any combination of concrete strength, weather conditions, speed of floor construction, and the ratio of live load to dead load of the basic design. An old contracting adage is still true: the shadow of the boss is worth 30 men on the job.
