Material handing costs- at least as far as formwork is concerned- starts when the forms are first delivered to the job. From there on, each movement of forms costs money. To overcome some of these costs, try to locate the forming materials as close as possible to their first use. Forms should also be stacked in neat piles, and the various sizes kept in separate stacks. This will minimize confusion when workmen are trying to find a specific size, and it will avoid the possibility of moving forms to find a size. Hardware should also be stored in convenient containers for easy moving and to prevent hardware loss. Ties, when shipped to the job site, are separated or packaged according to size and type. If the packages are grouped according to the job schedule you'll avoid both confusion an the possibility of using the wrong size tie. Gang forming can solve a number of problems for contractors. The size of a gang is determined by many factors. One of these factors is the method by which the form will be moved or handled. Normally, most large gangs are handled by crane. The crane usually performs other operations in between the erecting and stripping. At times the individual forms will be erected in place and stripped as a gang, rather than building the gang on the ground. This is done to meet certain job conditions and leave the crane free to do other work. Rollaway sections offer another means of handling forms particularly on tunnels. The forms are mounted on scaffold frames or job built frames with adjustable screw legs and wheels. The screw legs are used to bring the section to proper grade. To move the section ahead, the screw legs are taken up, allowing the section bear on the wheels and be moved. In order for the section to come down on the wheels, a hinged corner or rib is employed so that the sides may be swung in and the section lowered. To reset, the reverse is accomplished and trench jacks used to hold the sides out to proper line.
