Architects prepare the technical or "working" documents (construction drawings and specifications), usually coordinated with and supplemented by the work of a variety of disciplines [i.e., with varied expertise like mechanical, plumbing, electrical, civil, structural, etc.] engineers for the building services and that are filed for obtaining permits (development and building permits) that require compliance with building, seismic, and relevant federal and local regulations. These construction drawings and specifications are also used for pricing the work, and for construction.
