Dynamic improvements in the field of architecture programs have revolutionized the planning, but still not the building permit process of the 21st century. No matter which technological tools the architect uses, the delivery of all necessary permitting documents throughout Austria, has to be made in paper form. Few 'flagship' countries (such as Singapore, isolated cities in the USA) have begun with the use of new technologies. Delivery of required forms through the Internet, tracking of project status at any time and therefore rapid intervention if the forms are incomplete, could significantly reduce the time required for obtaining a building permit. Furthermore, the implementation of Building Information Modeling (BIM) in building permit process is a big step up to automatic checking. This paper explores possibilities of application of new Technologies in the Vienna building permit process. The research consists of an empirical and a practical part. In the empirical part, the data were collected using written and oral survey. A Questionnaire was filled in by employees of the Vienna building authority and designers working in Vienna and using BIM technologies. The survey provides an overview of possible acceptance and application of IT technology in the building permit procedure. In the practical part of the research, a BIM model of a residential building in Vienna was developed. It was then checked against a specially created ruleset in the computer program Solibri Model Checker (SMC) in order to demonstrate that input and review of building regulations is already possible with the existing software. The aim is to develop a modernization concept that could be applied, step by step, in the Vienna building permit process. This can lead to Digital Permitting Process as well as partly and fully automatically computer-assisted checking verification. Digital Permitting Process replaces paper format trough digital format in all process steps which enables optimized file management and constant permit tracking. This is a prerequisite for all other modernizing steps which could lead to a more efficient and faster process. Furthermore, computer-assisted verification is possible through the use of BIM and powerful computer programs, such as SMC. Currently some law points are not testable by SMC, which implies a partly automated computer-assisted verification carried out by Viennese building authority. Creation of a BIM-model of the Vienna city development and constant expansion of SMC ruleset makes fully automated computer-assisted check via an online platform quite possible in the future. Both scenarios should lead to improvement in quality of building checking process.
