This paper addresses critical success factors for the delivery of BIM projects. The lack of experience with BIM projects on both the demand and supply side often leads to insufficient project teams, unsatisfied clients, schedule, and cost overruns. In order to better structure and control the information delivery in BIM projects requirements, planning and delivery must be standardized. The latter was achieved by EIR (Exchange Information Requirements), new BIM roles, BEP (BIM Execution Plan), and specified digital handover, which must be supported by a common data environment (CDE). This paper provides an analysis of the characteristics of BIM project delivery and duration in Architectural and Engineering companies in Slovakia. The analysis is based on the web survey of BIM managers and coordinators, which reveals that a significant amount of BIM project efforts must be executed by BIM specialists. The results also graphically depict the scope of critical BIM activities across project phases. The presented study is relevant for various project stakeholders and allows for a deeper understanding of the resources needed for the successful delivery of BIM projects in terms of adequate project team capacity, capability, organization, and planning.

Building information modeling (BIM) brings several benefits to design and construction companies, especially in higher efficiency and quality of work. Several companies also use common data environment (CDE) systems, which speed up communication and collaboration between project participants. These can be used for occupational health and safety (HS) purposes and to increase the level of HS on construction sites. The first part of the article presents the state-of-the-art possibilities and approaches to implementing BIM in automatic or semi-automatic health and safety hazard detection. The following parts analyze the interviews with experts in BIM coordination, project management and health and safety in Slovakia and their answers to a survey, that covers the topic of safety hazard detection in BIM. The analysis shows that BIM is a suitable tool for increasing safety on construction sites, but there are several obstacles to achieving its full potential. The survey brings readers closer to the current state of the topic and the possibilities offered by BIM and CDE software in Slovakia. This paper, through the requirements and opinions of experts in BIM, project management and HS management, points out areas for further research and development of BIM software.

The building sector nowadays has come to the stage where it needs a “digital” renovation. This is to be accomplished by an introduction of change into the methodology of construction and using new tools and technologies, such as BIM technology. This paper gives an insight into the status of BIM adoption in North Macedonia. It presents the threefold actions toward introduction of BIM in the national construction industry. These actions refer to scanning the current situation regarding digitalization of the sector, then taking promotional actions to express the benefits of BIM, and finally identifying and proposing the most suitable measures, summarized in the proposal of the National Roadmap for BIM adoption. The methods used consist of a brief literature review of the global status of BIM development. Then, the results of a survey conducted on more than 300 respondents representing a sample of building professionals in the country are discussed, and the barriers for successful BIM adoption are accordingly identified. The next step is to showcase the potential benefits of BIM for assessment of energy performance of buildings. As a final point, the conclusions drafted toward identification of the most important challenges are addressed in the proposed National Roadmap for BIM adoption.

One of the fundamental issues of site plan development is the location of a tower crane which needs to be designed to meet specific criteria and specific needs of structures. With today´s traditional techniques it is quite difficult to consider optimal position and to select adequate technical parameters of a tower crane. This task is rather time consuming and complicated. With use of Building Information Modeling (BIM) this process can be simplified and the tower crane can be designed more effectively considering various criteria.This paper focuses on obtaining the data of all relevant parametric objects from IFC file and using them to compute optimal position of a tower crane. A suggested position is evaluated from the perspective of travel time of a hook, travel distance and length of jib needed to deliver all elements and materials. Data obtained from IFC model are compared with workload curve of a tower crane to ensure constructability and safety.As a result, map of criteria is done according to the coordinates of a tower crane arranged together with above-mentioned parameters to indicate differences between all possible locations.

One of the most important parts of construction work is the verification of the geometry of the parts of structures and buildings constructed. Today this procedure is often semi- or fully automated. The paper introduces an approach for the automated verification of parts of buildings, by comparing the design of a building (as-planned model), derived from a Building Information Model (BIM) in an Industry Foundation Classes (IFC) exchange format to a terrestrial laser scanning (TLS) point cloud (as-built model). The approach proposed has three main steps. The process begins with the acquisition of information from the as-planned model in the IFC exchange format; the second step is the automated (wall) plane segmentation from the point cloud. In the last step, the two models mentioned are compared to determine the deviations from the design, and the as-built wall flatness quantification is also executed. The potential of the proposed algorithm is shown in a case-study.
