Problems in reconstruction projects, BIM uses and decision-making: Lithuanian case studies

The research deals with reconstruction projects investigation by applying statistical analysis and multiple criteria decision-making method, also research on application of Building Information Modelling (BIM) methodology for reconstruction projects. The implementation of reconstruction projects face a lot of problems, and the list of problems is identified when analyzing Lithuanian case studies. The analysis shows that it is necessary to monitor design, construction and maintenance stages both for quality control and information management during the whole project life cycle. According to suggested problem recognition methodology, the list of problems is analyzed in terms of occurrence in the projects and influence to the project. The complex solution is based on estimated problems significance as a result of statistical survey and expert survey by applying Analytic Hierarchy Process (AHP) methodology. Possible BIM uses for reconstruction projects are suggested to prevent the identified problems.
