Summary:

The concept of sophisticated digital-dynamic information modeling of buildings and their construction, known as the Building Information Modeling (BIM), has globally unified the academic, entrepreneurial and legislative circles in the expectation of reaching the full potential of the concept, like none other in the recent past. Basis and motivations of recent BIM researches lie mainly in the fact that the expected full potential of BIM has not yet been reached, and it was expected that it would already be. The fact supporting this is that it has been eight years since the European Commission's 2014/24 directive, which suggests the use of electronic information modeling tools for public construction projects, and BIM has not yet a standard for construction projects in EU. Among other things, one of the reasons is the most famous characteristic of the construction industry, i.e., reluctance in adopting new methodologies and trends. On the other hand, recent researches suggest that the awareness of the stakeholders in construction projects on BIM’s benefits is not yet at the level which would lead to its self-initiated application and development by the stakeholders. In this perspective, a step forward is found to be combination of the BIM concept and the optimization methods. The aforementioned combination in the literature is known as active BIM approach. The main goal of the approach is the synergy between the two approaches in solving the standard construction project management requirements, i.e., project performance criteria: i) minimal costs of the construction; ii) minimal duration of the construction; (iii) the longest phase of the projects’ lifecycle, i.e., maintenance and exploitation, should be strategically planned and successfully analyzed, which corresponds to the Directive 2010/31/EU and legislative in most EU members. Besides the aforementioned difficult adoption of new methodologies and technologies, construction industry is known for its low efficiency and projects with the most number of safety issues which force a constant reengineering of the industry regarding its safety issues. Researchers worldwide indicate that BIM has proven potentials to be a platform that can simultaneously deal with efficiency and safety issues of construction projects, making BIM as the “missing link” and spotlights the motivation for BIM’s application level-up. Consequently, the goals of this project proposal are as follows: 1. To develop the basis for continuous active BIM approach in all phases of the projects’ life cycle in terms of construction projects’ efficiency and safety, according to the recommendations of earlier researches. 2. To structure the methodology, constraints, and potentials in the implementation of the active BIM for cost and time planning of building construction. 3. To develop the strategy, plan, and program of the project team’s applications on EU-funded research projects, in order to team could continue to work on the subject. 4. To include young scientist, from partnership institutions, into the successful collaboration established by the project leaders. In this project proposal young scientist involved are either just recently defended their doctoral thesis or they are doctoral students (namely, in the Croatian team: Mihaela Domazetović defended her doctoral thesis in February 2022, Dino Obradović has a defined date of the doctoral disputation for 31st of March 2022, Marko Čorak is a doctoral student on the first year; Marina Blažičević, Toni Bionidć and Domagoj Demšić are students on the master level; in the Slovenian team: Borna Dasović is a 3rd year doctoral student, Mateja Držečnik is preparing the doctoral thesis disputation for this year). 5. To publish two mutual scientific articles in which the project’s results will be presented. The expected results of this project proposal arise from the fulfillment of the project objectives: 1. Defined problems and constraints of the active BIM application in all phases of the life cycle of construction projects. 2. Tested proposed methodology for applying the active BIM for cost and time planning of building construction, as well as the cost-optimal analysis of the energy efficiency of buildings during their construction, use and maintenance. 3. The project team's application plan and program for EU-funded research projects, where the team will devote to the detailed research of the issues defined in this project.
