This paper presents a review of academic papers analysing the work of international researchers on digital projects and their evaluation. Digital projects have many advantages over traditional (physical or analogue) solutions. These advantages stem from their flexibility, scalability and the application of technology. Four digital projects are analysed in this thesis: 1) the overhaul of a part of Smėlynės Street in Panevėžys (from the railway crossing to the city boundary); 2) the overhaul of the Klaipėdos St., Projektuotojų St., Panevėžys, Dariaus ir Girėno St. intersection into a roundabout; 3) new construction of the link of J. Janonio St. with the Via Baltica bypass; 4) reconstruction of the intersection of J. Tilvyčio St., V. Alantas St. in Panevėžys into a roundabout. The project evaluation criteria were divided into three groups: design, organisation and construction. The evaluation criteria for the project were divided into three groups: organisation of design works and construction. In order to select the significance of the evaluation criteria, a survey questionnaire was presented with questions that would help to reveal the opinion of professionals on the use of wood composite beams for the installation of building slabs. The survey was carried out with 24 respondents, 89.8% of whom work in road construction and design and 10.2% in building construction and design. The multi-criteria methods TOPSIS and COPRAS will be used. After the survey, the significance of the criteria has been established and the agreement of the expert survey has been calculated. It was found that the expert survey is concordant at all stages, with a concordance coefficient of 0,756÷0,908. The calculation of the total efficiency scores by TOPSIS method showed that the most efficient project among the selected ones is the reconstruction of the intersection of J. Tilvyčio St., V. Alantas St. in Panevėžys into a roundabout, with a total efficiency of 2.546 points. The second most efficient is the reconstruction of the intersection of Klaipėdos St., Projektuotojų St., Dariaus ir Girėno St. in Panevėžys into a roundabout, with a cumulative efficiency score of 1.704. The third is the new construction of the J. Janonio Street link to the Via Baltica bypass: its overall efficiency score is 1.496. The least efficient is the major repair of the part of Smėlynės Street in Panevėžys (from the level crossing to the city boundary). This project has a cumulative efficiency score of only 1.346. The calculation of the total efficiency percentages using the COPRAS method shows that the most efficient project among the selected ones is the reconstruction of the intersection of J. Tilvyčio St., V. Alantas St. in Panevėžys into a roundabout, with a total efficiency of 30%. The second most efficient is Klaipėdos St., Projektuotojų St. in Panevėžys, The third is the new construction of the J. Janonio Street link to the Via Baltica bypass: its overall efficiency is 24%. The least efficient is the overhaul of the part of Smėlynės Street in Panevėžys (from the railway crossing to the city boundary): the overall efficiency of this project is only 21%. |
