Interconnection of Construction-Economic Systems with BIM in the Czech Environment

The need to use Building Information Modelling (BIM), which brings multiple benefits, including sustainable construction, in the Czech Republic is also reflected in the area of construction-economic systems. Construction-economic systems include building cost estimation, LCC calculation and facility management. The Czech construction sector is hampered by the diversity of these systems, despite the need for them to be interconnected and share data amongst themselves. For this reason, previous research has proposed a general connecting database to integrate data from the individual systems and effectively share them also within the framework of BIM designing. This paper generally describes further possibilities of expanding the connecting database to include another level. Specifically, this is demonstrated on one of the functional parts, i.e. the wall. A more detailed classification with attributes necessary for conclusive listing in the price database is proposed for the selected functional part.
