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.
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.
Building Information Modeling (BIM) is one of the main tools of digitization and enables the achievement of higher process efficiency, introducing new procedures to which companies on the market must adapt. There is a need for new professions that will ensure correct procedures and control mechanisms within the scope of defining, executing, and handing over BIM projects. This article focuses on the analysis of the rate of BIM adoption in Slovakia, especially in the field of BIM management and coordination in order to monitor the situation regarding the operation of specialized positions such as BIM managers and coordinators, based on data from industry research performed in the form of anonymous on-line survey.
Nevyhnutným predpokladom na kvalitné vyhotovenie stavebných konštrukcií aktíva je komplexný manažment kvality založený na efektívnom plánovaní, vyhotovovaní a archivácii jednotlivých kontrol stavebných prác, surovín, výrobkov a zrealizovaných konštrukcií. Takýto manažment je možné dosiahnuť digitalizáciou kontrolných a skúšobných plánov (KSP), ktoré sú založené na princípoch a možnostiach, ktoré ponúka Building Information Modeling (BIM) a Common Data Environment (CDE). Príspevok na konkrétnych príkladoch popisuje možnosti, postupy a výsledky vytvárania KSP v CDE systémoch založených na BIM.
