Industrial automation systems and integration - Product data representation and exchange - Part 225: Application protocol: Building elements using explicit shape representation

This part of ISO 10303 specifies the use of the integrated resources necessary for the scope and information requirements for the exchange of building element shape, property, and spatial configuration information between application systems with explicit shape representations. Building elements are those physical things of which a building is composed, such as structural elements, enclosing and separating elements, service elements, fixtures and equipment, and spaces. Building element shape, property, and spatial configuration information requirements can be used at all stages of the life cycle of a building, including the design process, construction, and maintenance. Building element shape, property, and spatial configuration information requirements specified in this part of ISO 10303 support the following activities:(a) concurrent design processes or building design iterations;(b) integration of building structure designs with building systems designs to enable design analysis;(c) building design visualization;(d) specifications for construction and maintenance;(e) analysis and review.The following are within the scope of this part of ISO 10303:(1) explicit representation of the three-dimensional shape of building elements using boundary representation (B-rep) solid models, swept solid models, or constructive solid geometry (CSG) models.(2) the spatial configuration of building elements that comprise the assembled building;(3) building structures that represent physically distinct buildings that are part of a single building complex;(4) non-structural elements that enclose a building or separate areas within a building;(5) the shape and arrangement of equipment and service elements that provide services to a building;(6) the shape and arrangement of fixtures in a building;(7) specification of spaces and levels;(8) the shape of the site on which the building will be erected;(9) specification of properties of building elements, including material composition;(10) specification of classification information;(11) association of properties and classification information to building elements;(12) changes to building element shape, property, and spatial configuration information;(13) association of approvals with building element shape, property, and spatial configuration information; and(14) as-built record of the building.
