17 Project information Short project description Nemetschek Engineering User Contest 2011 - Category 1: Buildings 1 Winner - Special Jury BIM Prize Owner Europolis Orhideea BC Architect BEHF Ebner Hasenauer Ferenczy ZT - Austria General Contractor MIMO Group Engineering Office Inginerie Structurala s.r.l. Location Bucharest, Romania This project comprises two adjoining office buildings in the shape of a butterfly. The site is located on the left side of the Dambovita River where three underground aquifers had to be dealt with. The composite structure will be made out of steel and reinforced concrete. As Romania is lying in a seismic zone, the most important and decisive verification was the checking of the structure against earthquake. The basements were analyzed together with the superstructure. In this way the entire behaviour of the building was taken into consideration. The soilstructure interaction was taken into account by modelling the soil as a Winkler elastic support area. Orchidea Tower Bucharest, Romania Quote of the Jury “The spatial tall Orchidea tower structure (butterfly plan) was a nice demonstration of integrated design from the dynamic earthquake computation of the composite steel and reinforced concrete structure. Good use of 3D modelling and 3D structural analysis software. The entire behaviour of the structure, also soil-structure interaction, could be taken into account.”
