World crisis has heavily affected slovenian economy. It forced slovenian companies to find
work in foreign markets where the competition is on higher level. On those markets the BIM
has already been demanded by contractors, which leads integrated delivery method. To
demonstrate the use of BIM I used structure with combined underground garages. On the
ground floor the structure is separated into three small towers with four floors. The structure
has approximately 8500 m˛ of net floor area. Existing project documentation was made for
preliminary design with a lack of information about the structural system. With use of BIM
tools I created architectual and structural model and model of the construction phase.
ArchiCAD was used to make parametrical 3D building information model, from which I
prepared project documentation. In addition I was able to extract quadratures of net area and
full lenght of the Schöck Isokorb elements. Model that was created in ArchiCAD helped me to
create a structural model in Tekla Structures. Furthermore I scheduled the project using gantt
chart and imported it into Microsoft Project to make detailed scheduling easier. Due to typical
cyclic operations of construction crews that I used in the graduation thesis MS Project was
further exported into the Vico Control scheduling software, where a detailed flowline chart
was developed along with network schedule. Construction of the load bearing structure was
distributed into cycles and further into horizontal and vertical components that require
location based dependencies of formworks, reinforcements and concrete pouring activities.
On the basis of both charts in Vico Control I speed up the construction with an optimization of
the charts creating optimal intervals between proceses and made resource graph. In the end
I created an animation of organization of constructional site in SketchUp.
