The project took place in Tuzla, Bosnia and Herzegovina. It is an office building with a gross area of 2500 m2. This building has 3 levels, and the structural system is a frame structure with shear walls. All slabs are monolithic reinforced concrete slabs with a total thickness of 18 cm, with the exception of the slab on ground, which is 15 cm thick. We provided our client with structural design and drafting and for our purpose we made a BIM model with Revit.
