Much has been said about the advantages of gang forming and handling, as well as for hand setting and its advantages. But very little had been said about combining the two operations for greater profits. One successful method is to erect one side and erect the other as you place. Depending on whether it's a straight or curved wall, the gang for one side can be made up on the ground or built up in place. The first lift of forms is erected on the opposing side, ties inserted, placing started at one end. As the placing progresses down the wall, the second lift of forms can start and follow up the placing. This cycle is repeated until the top of the wall is reached. This method helps provide a more continuous cycle without delays and none of the men are idled between operations. An integral part of any forming system is the tying and this can be a problem due to design. To solve this problem, a specially made flat tie with a hole in the center can be used. Forms can be set for the first wall on both sides. A third setting of forms completed the outside forming of the second wall. The tie was connected at each end for the outside forms of both walls. The hole or slot in the center of the tie allowed for forms for the first wall to be connected. Pier forming of the deck and two step drophead caps can be easy if planned carefully. If the pier contains a quantity of pile caps, it is best to design a fast, re-usable system, as done with one contractor. The prestressed concrete piles were 20 inches square. Fillers of proper depth and length were assembled into a rigid square with connecting hardware. Above this standard prefab, inside corner forms were mounted to the previously connected fillers. Larger forms were connected to the corner forms. The whole assemble formed the platform or formwork of the upper drophead cap section. Smaller, flat gang sections were assembled and set between the lines of piles to form the flat areas. These could be handled manually and were set on supporting timbers. This method proved to be quite fast and allowed much of the work to be accomplished from above, where the men could work safely and with more room. This spotting technique was devised for placement and erection of small diameter tanks, and where the footer is to be cast integrally with the wall itself. Having a fairly smooth and markable ground surface, a template was used to mark off the prescribed area. The first step was to establish a center point of the tank with a stake.. Next the pre-cut plates, cut to the exact curvature, are positioned and forms for the inside can be erected. After this is completed, secure the cantilever brackets over the top of the forms, since the footing will be placed with the wall.
