The building permit is an indispensable connection between the approval authority and the executive client within the construction process. Moreover, sustainability criteria do not have sufficient regard in the building permit process in the area of research. To lay the foundation for a state-of-the-art digitalization of the building permit process, the study identifies the information requirements relevant to implement the BIM methodology taking into consideration the available sustainability aspects relevant to the process. A detailed evaluation of the building permit process and the analysis of projects that have gained building permission in the last five years in the area of study of South Tyrol (Italy) gives us a better understanding of the organizational structure and responsibilities in the process. The authors use the data of in-depth process analysis to assess a defined catalogue of basic requirements for BIM methodology in the building permit process. As a result, the analysed BIM-integrated approach enables an early-stage identification of approval compliance, which can be evaluated in the building permit process. A good understanding of the current process must be considered a key factor of a successful introduction of BIM for the building permit procedure.
Abstract. The digitalization of the process for building permit (involving the use of 3D information systems) is seen as a priority in a wide part of the world. Since it is a very multidisciplinary use case, involving a variety of stakeholders tackling complex issues and topics, some of them joined their efforts and skills in the European Network for Digital Building Permit. The initial activity of the network, after a review of on-going experiences, was a workshop to share knowledge about the topics involved and to identify the main ambitions of the network with respect to three pillars (i.e. Process – Rules and Requirements – Technology) and the related requirements. It was achieved through a collective brainstorming activity guided by digital tools, whose results were further analysed in a post-processing phase. Such results are presented in this paper and will be the base for planning the future network activity.
Scheduling is one of the driving factors in the success of a construction project and it is a critical step for all team members as it provides guidance to where and when they should perform work. Despite its important role, scheduling is typically based on approximate time schedules, which often lead to delays and extra costs. This is due to the lack of visualizing the real effort before the construction phase starts, as well as the difficulty in managing a large number of uncertain factors using traditional approaches. According to many studies, building information modeling aims at improving the quality of construction scheduling by enabling virtual simulations and by promoting digital working space. In this context, following questions arise: How does BIM support the digitalization of the scheduling process? Which are the benefits and criticisms of applying BIM for construction scheduling in a SME environment? This paper aims at evaluating the role of BIM in the digitalization of the construction scheduling process and its suitability for SMEs companies through a real case study. The paper starts with a state of the art on relevant applications of BIM for construction scheduling. Afterwards, the paper suggests a framework for combining construction scheduling and BIM, considering a case study used to verify the feasibility of the integrated method. Finally, findings from the implementation of the proposed framework are summarized, particularly examining the role of BIM in digitalizing the construction scheduling process, as well as the benefits and criticisms of its applicability to SMEs.
Growing interest is awarded to the digitalization of the building permitting use case and many works are developed about the topic. However, the subject is very complex and many aspects are usually tackled separately, making it very hard for traditional literature reviews to grasp the actual progress in the overall topic. This paper unveils the detailed state of the art in Digital Building Permitting (DBP) by critically analyzing the literature by means of a set of coding tags (research progress, implementation, affected DBP workflow steps, ambitions addressed) assigned by a multidisciplinary team. The mainly addressed aspects of the digitalization of building permits resulted to be the technologies to check the compliance of design proposals against regulations, followed by the digitalization of regulations. Lacking aspects are instead the involvement of officers, scalability of solutions and interoperability of data, intended both as data validation and as integration of geoinformation with building models.
