Foundation Plan A FOUNDATION Program is a summit view of the footings or foundation walls, showing their expanse and their location by distances betwixt center lines and past distances from reference lines or boundary lines. Actually, it is a horizontal section view cutting through the walls of the foundation showing beams, girders, piers or columns, and openings, forth with dimensions and internal composition. The foundation plan is used primarily by the building coiffure who will construct the foundation of the proposed construction. In nigh SEABEE construction, foundations are built with physical- masonry units and cast-in-identify concrete. Effigy 10-xviii shows a programme view of a structure as it would look if projected into a horizontal plane that passes through the structure slightly below the level of the top of the foundation wall. The plan shows that the principal foundation will consist of 12-in. concrete-masonry unit of measurement (CMU) walls measuring 28 ft lengthwise and 22 ft crosswise. In this program, the CMU walls are identified by the standard symbol for concrete block. Ideally, a specific note should exist added to phone call out the cloth. A girder running through the center of the building will be supported at the ends by two 4-by 12-in. concrete pilasters that will barrel against the end foundation walls. Intermediate support for the girder will be provided by two 12-by 12-in. concrete piers, each supported on xviii- by 18-in. spread footings, ten in. deep. The dotted lines around the foundation walls signal that these walls will as well rest on spread footings. Yous demand relative information about the total concept of the structure earlier y'all can draw the foundation plan. You must make a conscientious study of the materials and construction methods used, notice the blazon of foundation used, and clarify the relative position of the framing and the foundation wall or footing. You must also make reference to all of the applicative wall sections and typical sill details found in your texts and reference materials, such equally the Architectural Graphics Standards before you start the founda- tion plan. In well-nigh drafting practices, information technology is customary to utilize the footing floor plan to develop the Figure 10-xviii.-Case of a foundation programme. 10-21
