These are motivated in part by the remarkable improvement in computer hardware capability, the introduction of the Internet, and an extraordinary decline in cost. New concepts in computer design and in software are also contributing. For example, the introduction of personal computers using microcircuitry has encouraged the adoption of interactive programs because of the low cost and considerable capability of the computer hardware. Personal computers available for a thousand dollars in 1995 have essentially the same capability as expensive mainframe computer systems of fifteen years earlier.
Computer graphics provide another pertinent example of a potentially revolutionary mechanism for design and communication. Graphical representations of both the physical and work activities on projects have been essential tools in the construction industry for decades. However, manual drafting of blueprints, plans and other diagrams is laborious and expensive. Stand alone, computer aided drafting equipment has proved to be less expensive and fully capable of producing the requiring drawings. More significantly, the geometric information required for producing desired drawings might also be used as a database for computer aided design and computer integrated construction. Components of facilities can be represented as three dimensional computer based solid models for this purpose. Geometric information forms only one component of integrated design databases in which the computer can assure consistency, completeness and compliance with relevant specifications and constraints. Several approaches to integrated computer aided engineering environments of this type have already been attempted.

這些被刺激一部分由在電腦硬體能力的卓越的改善, 網際網路的介紹, 和一非凡decline 在費用。新概念在電腦設計和在軟體並且貢獻。例如, 個人電腦的介紹使用microcircuitry 鼓勵了交互式程式的收養由於電腦硬體的低成本和可觀的能力。個人電腦可利用為一千美元在1995 根本上有能力和昂貴的主機系統十五年更加早期一樣。
電腦圖表為設計和通信提供一個潛在地革命機制的其它恰當例子。物理和工作活動的圖解表示法在項目是根本工具在建築業數十年。但是, 手工起草圖紙、計劃和其它圖是費力和昂貴的。站立單獨, 電腦輔助的起草的設備證明較不昂貴和充分地能生產要求的圖畫。極大, 幾何學資訊必需為生產渴望的圖畫也許並且被使用作為資料庫為電腦輔助設計和電腦整合的建築。設施組分可能代表作為三維電腦為主的固體模型為這個目的。幾何學資訊形成只電腦可能保證一貫性、完整性和遵照相關的規格和限制聯合設計資料庫的一個組分。對這型的聯合電腦輔助工程環境的幾種方法已經試圖Source(s): 123
