Design Automation for Site Development

场地开发的设计，如商业建筑或住宅分区，整合了建筑师布置场地，一些工程师设计结构，场地分级，雨水排水和提供公用设施的工作，以及在颁发建筑许可证之前必须由市政府官员批准设计的审查。在当前的设计实践中，很少有这些个人工作的自动化集成。因此，设计、审查和重新设计的持续循环既耗时又昂贵，而且产生的设计是可行的，而不是最优的。拟议的研究旨在通过计算机集成其组成活动来使设计过程自动化：一个以场地地形模型为核心的中央数据库，使用先进的CAD图形系统将场地的现有和拟议条件可视化，使用有限元方法更准确地计算场地的雨水排水，还有一名设计审查员，将城市的条例和良好设计实践的规则结合起来，这样设计就能从一开始就按照可接受的路线进行。美国几个地点的现有场地开发将被重新设计，以展示如何使用自动化系统更快、更有效地进行设计。

The design of site developments, such as commercial buildings or residential subdivisions, integrates the work of architects laying out the site, a number of engineers designing the structures, site grading, storm drainage, and provision of utilities, and review by city officials who must approve the design before issuing a building permit. There is very little automated integration of the work of these individuals in current design practice. As a result, the continual cycle of design, review and redesign is time-consuming, expensive, and produces feasible rather than optimal designs. The proposed research aims at automating the design process through computerized integration of its component activities: a centralized database keyed to a model of the site terrain, visualization of the site in its existing and proposed conditions using an advanced CAD graphics system, more accurate computation of storm drainage over the site using the finite element method, and a design checker incorporating the city's ordinances and rules of good design practice so that the design proceeds along acceptable lines from the beginning. Existing site developments at several locations in the U. S. will be redesigned to show how design can be carried out quicker and more effectiveny with an automated system.
