The desired relationships of all the programmed spaces are shown graphically on the Adjacency Diagram. The four building access points – public, group, staff, and service –as well as doorway access within the building are shown with arrows. In some locations, an overhead door, indicated by a double line and OH, will be required to accommodate the movement of large objects. Spaces that are to be adjacent are connected with a solid line, and those that are to be near each other are connected with a dashed line.
