Dignitary Protection Service building in Vilnius (BIM)

An administrative building of the Dignitary Protection Service (T. Ševčenkos g. 13, Vilnius) was designed. The purpose of the reconstruction was to reconstruct the existing building of the Institute of Geology and adapt it to the activities of the Dignitary Protection Service. The designed administrative building with special purpose premises is located in the new part of Vilnius city. The building has 5 floors and a superstructure. The building consists of two blocks. The part of the building along the street harmoniously blends with the buildings the architecture of which is typical for the new part of the city. For the façade decoration clinker was used. The higher block in the yard is bigger. The biggest challenge was to accommodate in the reconstructed building all the spaces that meet the expectations of the building user that had very specific needs.

According to the project solutions, existing building of energy class E had to be reconstructed into an administrative building of energy class A (dynamic modelling and energy efficiency calculations were performed when preparing the project). Inside the designed building, it was indicated to install secured premises of security zone II, the installation and security requirements of which were specified in the Description of the Requirements for the Physical Protection of Classified Information and the Procedure for their Implementation. On the 5^th floor of the building, a 24 m long and almost 15 m wide shooting range (area of the shooting range: almost 350 m²), which had to be intended for the activities of the Dignitary Protection Service, was designed. Within the scope of the project, recommendations for the improvement of the sound insulation of the shooting range, printing premises, and meeting rooms/cabinets have been prepared according to which the project solutions have been prepared. When planning and modelling the internal spaces of the building, the connections between the premises were carefully analysed taking into account their functions specified in the design task, movement flows were studied, and possibilities of adapting innovations to various functions and changing needs were analysed. Due to the specifics of the activity performed by the building user, the building had to have many different premises (weapons storage, training premises, archives, short-term detention premises, printing, meeting, and inspection rooms, etc.). Interior design solutions were prepared for part of the premises. The building under reconstruction was surrounded by residential buildings, and therefore, in order to ensure that the reconstruction solutions would not violate the legal requirements for natural lighting and would not harm the interests of third parties, calculation of solar insolation was performed. The project also envisaged solutions of the use of renewable energy resources, i.e., the project involved the installation of a solar power plant on the roof (the power generated by the solar power plant can be used in the building). The land plot (cadastral No. 0101/0056:98), where the building is located, is in the historical part of Vilnius, Naujamiestis (unique code: 33653, block No. 63), and therefore the part of the project related to the cultural heritage protection was prepared. The territory of the object to be reconstructed and the entire building were adapted to the needs of people with disabilities.

The project was prepared by applying the building information modelling (BIM) process which allowed to generate digital representations of the objects. The BIM project was coordinated by the BIM coordinator, who was entrusted with the preparation of the BIM plan, coordination of the process and model development, and analysis of intersections. The BIM model was developed at LOD 300.
