The presented research contributes to the bulk of knowledge on the classification systems with the measures to harmonise, simplify and prepare these for the users and workflows in the smart planning in AEC industry.

This newly developed classification system simplifies the mapping processes due to its domain specific character. The proposed classification system is implemented and tested in the central building data storage, where the data exchange towards structural analysis digital tools is performed. Singular interpretation processes, which are the key element for the development of classification are described. The proposal focuses on the interpretation processes that are an inevitable but neglected part of the data exchange process between architectural and structural analysis models. Based on the review and identified deficiencies, a proposal for a comprehensive classification system is created to support the interdisciplinary exchange. This paper presents a review and evaluation of existing classification systems through a comparative study of several BIM-based tools for architecture and structural analysis, as well as the standards related to the classification, thereby identifying the deficiencies for a seamless exchange. However, there is a mismatch between the digital tools in the AEC industry and relevant standardisation due to: a) lack of standards for digital tools, and b) the standards developing slower than the digital technology thus increasing differences between numerous exchange workflows and stepping away from a seamless exchange. The digital design tools aim to meet end user needs, support existing design and construction workflows, and bring innovations in the AEC industry. Thus, it is not surprising that many companies are loyal tenants of the Tech Gates Vienna.Interdisciplinary digital model exchange in the AEC industry is faced with numerous difficulties, involving both process and technology problems. Breathtaking views, state-of-the-art technology and a terrace make the Sky Stage a unique part of the Tech Gate Vienna.

One of the highlights is located on the 19th floor. Also it is possible to darken the room by blinds.

The 113 sqm room offers optimal lighting conditions and is surrounded by a terrace. On the seventh floor is the so-called Ring Stage. The Multimedia Stage, which offers not only sufficient space but also optimum technical equipment on an area of вЂ‹вЂ‹750 sqm, is also ideal for this purpose. For meetings and conferences, for example, you can use the Business Stage rooms. There are also rooms for events, seminars, meetings, small fairs or workshops. Small offices have 30 to 60 sqm, medium to about 100 sqm and large offices are available from 200 sqm. The Tech Gate Vienna has small, medium and large office space. Shareholders are WPWS VermГ¶gensverwaltung GmbH, Wien Holding GmbH and FFG вЂ“ Г–sterreichische ForschungsfГ¶rderungsgesellschaft mbH. The carrier company is the Tech Gate Vienna Science and Technology Park GmbH. The total gross floor area is 18,000 sqm. 19 floors have a lettable area of вЂ‹вЂ‹11.00 sqm. Second stage of construction (2004-2005): During these years the 75 meter high tower was built.It has a gross floor area of вЂ‹вЂ‹36,000 sqm, of which 15,000 sqm can be rented. First stage of construction (1999-2001): During this time, the 26 meter high gate component was erected.It was built from 1999 to 2005 in two stages: The plans came from the Austrian architects Wilhelm Holzbauer and Sepp Frank. The Tech Gate Vienna is a science and technology park in the Donau City.
