Direction curved panels must be carried after being formed (F).
Level area required to lay panels on the ground for seaming. Building will not be consistent if panels are not straight when seaming (G).
Space required for crane operations (I-I).
The design of the foundation for a K-span building depends on the size of the building, the existing soil conditions, and the wind load. 'he foundations for the buildings are simple and easy to construct. With the even distribution of the load in a standard arch building, the size of the continuous strip footing is smaller and therefore more economical than foundations for more conventional buildings.
The concrete forms and accessories provided are sufficient to form the foundations for a building 100 feet long by 50 feet wide. When a different configuration is required, forms are available from the manufacturer.
The actual footing construction is based, as with all projects, on the plans and specifications. The location of the forms, the placement of the steel, and the psi (pounds per square inch) of the concrete are critical. The building panels are welded to the angle in the footer before the concrete is placed. Because of this operation, all of the aspects of the footer construction must be completely checked for alignment and squareness. Once concrete is placed, there is no way to correct errors.
As mentioned above, forms are provided for the foundation. Using table 8-1 as a guide, figure 8-15 gives you a simple foundation layout by parts designation. As noted in figure 8-15, the cross pipes are not provided in the kit. They must be ordered when the project is being planned and estimated.
