USING CADD FOR MAJOR TRANSPORTATION PROJECTS

Developments in software and hardware have made it possible to automate nearly the entire design and construction management process. A number of products are available for collecting data in the field which is then downloaded onto a workstation to assist in creating a digital terrain model. From this model, cross sections can be created and earthwork calculations completed using traditional or advanced algorithmic methods. MOSS, a frequently used algorithmic program is described. State-of-the-art CADD (computer aided design and drafting) systems utilizing relational database management technology make it easy to create, revise, store, update and distribute a host of engineering documents, including plan and profile sheets, cross section sheets, and title sheets with key maps and tabulations. Sophisticated new scanning devices to enter hand-drafted drawing into the CADD system, and developments in coordinate geometry software are also noted.
