About the project

Challenge, approach and results.

The diploma thesis addresses the comprehensive systematisation of legal relations between stakeholders in the construction process in Slovenia, with particular emphasis on the connection between contractual principles and technical execution of construction projects. It is established that in residential projects the contractual framework is most often standardised, which ensures greater legal certainty and fewer conflicts. In contrast, contractual arrangements for viaducts are subject to multidimensional complexity, the use of specialised clauses, higher legal and technical requirements and the inclusion of public interest, which requires advanced risk management, extended insurance and multi-stage approvals.

Solution and Method

The diploma thesis addresses the comprehensive systematisation of legal relations between stakeholders in the construction process in Slovenia, with particular emphasis on the connection between contractual principles and technical execution of construction projects. The fundamental problem stems from numerous challenges on construction sites, where unclear agreements about responsibilities and obligations often occur, and a lack of clear understanding of legal provisions amongst investors, designers, supervisors and contractors. Such lack of transparency results in delays, conflicts and reduces management efficiency and construction quality.

The purpose of the diploma thesis is a comparative analysis of contractual and organisational differences between the construction of a residential building and a viaduct, with the starting point of proposing solutions for improving contractual arrangements and project organisation. In the theoretical part, a systematic treatment of contractual principles, the Construction Act, the Public Procurement Act and professional norms and standards is carried out, which together form the legal framework of Slovenian construction. The research is based on the analysis of publicly available legislative sources, professional literature and practical examples.

The practical part includes a comparative analysis of a residential building and a viaduct in terms of legal, technical and organisational aspects.

Results

It is established that in residential projects the contractual framework is most often standardised, which ensures greater legal certainty and fewer conflicts. In contrast, contractual arrangements for viaducts are subject to multidimensional complexity, the use of specialised clauses, higher legal and technical requirements and the inclusion of public interest, which requires advanced risk management, extended insurance and multi-stage approvals. The analysis confirms that legal relations with pre-agreed responsibilities and the inclusion of all key participants in the preparatory phase of the construction project are the foundation of efficient execution, reduce the number of conflicts and enable better utilisation of professional knowledge and resources.

An efficient project team, supported by an interdisciplinary approach, is the key to success in modern construction.
