Computer-aided design (CAD)

  The designing of Phase 1 of the Central Terminal was begun with GDS software in 1992. The help of an AutoCAD program was also required to create the necessary profiles and detail drawings. As both the special designers and the Civil Aviation Administration employ also other CAD softwate, a separate conventer programme was needed to make CAD integration possible.

By the time the designing of Phase 2 began, the situation had changed - thanks to recent developments in hardware and software alike - to the degree where AutoCAD could be adopted as the basic software for the entire designing process, at the moment (1995) in its current version 13. Co-operation between different designers has become much simpler now that files can be used directly without the trouble of conversion.

A design project of this size involves team work combining the efforts of several architects and, consequently, several computers all connected to the local network. The vast numbers of design documents further require clearly defined rules for creating and maintaining CAD drawings. The design application of AutoCAD software has been the Kivi menu, and the tool used for data management the AutoManager Organizer software.

In addition to the local office network, it is essential that connections with other designers work as fluently as possible. The prerequisite of CAD integration is a databank which is open to all designers in the project, in this case an Internet-based service provided by the architect. At the core of this is a server with a high-speed connection to the Internet web. This means that the rate of data transfer depends solely on the Internet connection chosen by the user, e.g. a fast modem, ISDN or fixed network connection. In principle, this enables designers to work anywhere in the world, as long as there is a computer, suitable softwate and an Internet link at hand. This databank solution has proved faster and more reliable in active use than the traditional modem-based BBS type of model.
