About the Department
Department History
1922-03-24
After the Statute of the University of Lithuania was approved, 17 departments were established within the Faculty of Technology. At that time, there were no separate departments for structural engineering, and structural design was considered part of bridge engineering. The closest related unit was the Department of Bridges, which was responsible for teaching stone, wooden, steel, and reinforced concrete bridges.
1922-03-24
The Department of Bridges was established. The head of the department until 1940 was Ord Prof Silvestras Grinkevičius.
1923-02-01
Privatdozent Pranciškus Markūnas joined the Department of Bridges. He taught reinforced concrete, supervised design projects, and designed 19 reinforced concrete bridges and 16 buildings, including four churches.
1928-10-01
J. Gabrys was appointed Junior Assistant.
1930-09-01
J. Gabrys was promoted to Senior Assistant. He supervised the design of bridges and reinforced concrete structures, taught culvert design, and authored the textbooks “Culverts” (1930) and “Reinforced Concrete and Concrete Bridges” (1931).

Thesis abstract (EN)
The final Master’s thesis examines the possibilities for automating design clash detection processes by applying artificial intelligence (AI) methods in a BIM environment. The aim is to assess how AI can contribute to the digitization of design processes, increased efficiency and the growth of data value. The objective of this work is to analyze the literature, documents and technological solutions applied to automated clash detection in BIM projects using AI technologies, with the aim of increasing detection accuracy, reducing time costs, and improving the efficiency of the design process.
The analysis highlighted the importance of information integrity, structuring and effective data management, as well as the growing role of advanced technologies in this field. This study empirically investigates the potential applications of AI technologies in the specific context of BIM clash detection, evaluating their applicability, resource requirements and effectiveness. It was found that AI methods effectively solve mathematical and geometric tasks, but high-quality and consistent data preparation is essential for semantic data analysis. The importance of socio-technical factors-specialists’ competencies, trust in technology and organizational readiness - also became apparent.
To address the research problem, an experimental study was conducted, during which an AI model was developed and tested by analyzing different combinations of features and evaluating the results. The study identified key challenges, areas for improvement, and prospects for AI application in the field of BIM clash detection.
The thesis consists of an introduction, analytical-theoretical, methodological, and research-analytical sections, conclusions and recommendations, and appendices.

To ensure precise visualization and project coordination, a 3D model of the residential building is developed. In the structural analysis section, the internal forces of the load-bearing structures are calculated based on dead and live loads, and the required reinforcement for the structural elements is determined. A comprehensive set of graphical documentation is prepared, consisting of architectural-structural drawings and detailed working drawings of the load-bearing structures. Finally, the technological part of the thesis includes a technological card for the cast in place columns installation, defining the construction processes, quality control requirements, and occupational safety measures on site.

The final Bachelor's thesis designs a multi-storey residential building with administrative premises located at 12A Žygimantų Street, block C, Vilnius. The aim of the thesis is to develop the main architectural, structural, and technological solutions for the building, taking into account the loads acting on the structure and ensuring the load-bearing capacity, stability, and serviceability of the structural elements. The thesis consists of three main parts: architectural-construction, structural, and technological.
The architectural-construction part presents the initial project data, climatic conditions, loads, main structural materials, and design solutions for the foundations, columns, floor slabs, walls, roof, stairs, expansion joints, fire safety measures, indoor microclimate, and engineering systems. It also includes calculations of the thermal resistance of the building envelope.
In the structural part, a three-dimensional computational model of the building is developed using the finite element software SCIA Engineer 25. Permanent, imposed (live), snow, and wind loads are calculated, load combinations are established, and the internal forces acting on the structural elements are determined. Based on the obtained results, a monolithic reinforced concrete flat slab, reinforced concrete columns, and a pile foundation are designed. The technological part includes the preparation of a technological specification for pile foundation installation, the selection of construction equipment, a description of the pile installation process, permissible tolerances, occupational safety requirements, and technical-economic indicators.
The graphical part contains architectural drawings, structural working drawings, and a technological scheme for pile installation. Thesis volume: 206 pages.
