CPD Code : Formal Events
Speaker : David de Dios is an engineer hailing from Benidorm: the city with the most skyscrapers per capita in the world, towering over the sunny beaches of eastern Spain. Originally an alumni of the University of Alicante in Spain, he has travelled the world in over twenty countries spreading the word about the benefits of Open BIM technology in the AEC sector. With a cross-discipline approach, he found Open BIM a natural fit. Since his incorporation, he has presented in many conferences and seminars about Open BIM Quantities, highlighting the possibilities of new workflows in the industry and its implications for ongoing sustainability and digitalization efforts.

According to the CIC BIM Dictionary, the term Open BIM generally refers to the process of exchanging non-proprietary BIM models and other data. Open BIM is a universal approach to the collaborative design, realisation and operation of buildings based on open standards and workflows.

Thanks to technological advances in the construction industry, the Building Information Modelling (BIM) methodology has become a powerful tool that goes beyond the mere visual representation of architectural designs. As well as revolutionizing how projects are designed and implemented, BIM also offers an innovative approach to developing accurate and detailed Bills of Quantities. Through the use of intelligent data and 3D models with a high volume of information, construction professionals can now take advantage of the benefits of BIM modelling to automate the extraction of properties and quantities from project elements, this allows for quantities to be measured more efficiently and a direct correlation with cost databases.

Open BIM Quantities is an approach to prepare Bills of Quantities under the Open BIM environment. The speaker will explain with illustrated examples on how to take quantities and prepare Bills of Quantities in projects adopting Open BIM.
