<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>One of the core feature classes of the public safety database, this layer contains over 150,000 features throughout the county. It is used on all mapping products and applications. A sub-type is used to define building types; there are 13 types based on the Uniform Building Code (UBC): Assembly (1), Business (2), Camps (3), Education (4), Factory (5), High Hazard (6), Institutional (7), Laboratory (8), Mercantile (9), Residential (10), Storage (11), Miscellaneous (12), and Mixed Use (13). Most sub-types are further differentiated and controlled by asociated domians - see the Building SubType attribute and data model for details (Note: these are simplified from the earlier version based on primary subcategories of the UBC and operational input for life/fire safety).</SPAN></P><P><SPAN>The feature class is also critical to provide information about the building's characteristics. There are about 35 additional attributes intended to describe each building's construction (UBC codes I-V), roof, exterior wall and floor, building height and # of floors, fire protection, contact information, and appurtenance data. This information is used and summarized on each pre-plan's narrative.</SPAN></P><P><SPAN>All buildings that participate in a structure pre-fire plan are associated with the plans primary key PreplanID. Similarly, any appurtenance related to a building such as Rooms, Walls, FireComponents, Elevators, etc have inherent one-to-many relationships via the building features primary key, BldgID. These relationships are not explicitly defined in a relationship class as in earlier versions for performance considerations and ease of use.</SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
