The successful concrete contractor today must above all else be an expert on problems connected with the movement of concrete on the job site, and the know-how to use the method or methods of handling on any particular project which will result in the lowest cost. There is no single pat answer to the selection problem, and each job must be scrutinized with considerable care before a decision is reached, and even more particularly before a firm bid is offered. Undoubtedly the ideal way to handle concrete is to make it possible for ready mix trucks to discharge directly into forms. Just a little time spent readying the site, when no road or driveway is adjacent to the forms, frequently enables the trucks to drive up to them. It can save time, money and headaches. Unfortunately, the size or height of the project or the condition of the ground often renders it impossible to make such direct discharge of the ready mix. In these cases, the means of transporting the concrete from truck to forms becomes a question to consider. Buggies or carts are in effect just a variation on the wheelbarrow theme. They are becoming increasinly popular because of their speed and high capacities. Wheelbarrows long served as the standard materials handling unit in construction. It is now mainly used for short hauls and relatively small amounts of material. Elevator loaders and front end loaders are, in effect, power buggies that have the added ability of lifting the concrete hopper veritically. Fixed hoists are most frequently used for transporting concrete for high-rise buildings and towers. Buckets (also called hoppers) are usually employed when concrete must be lifted vertically (or lowered veritically) a considerable distance; for example, in the construction of a high-rise building frame. Chutting is not as common a practice as it once was but it still finds application, especially when used in conjunction with other concrete handling techniques. Belt conveyors have proved themselves valuable, especially on large jobs with extensive floor areas. Pheumatic equipment can also be used for handling and placing concrete.
