The Architecture Engineering and Construction (AEC) sector has been working on an increasing number of mega projects having large scale investments worldwide. The majority of these mega projects are infrastructure projects that are comparatively more difficult to manage in terms of yielding an expected return of investments while increasing quality and productivity. Today’s construction technology landscape offers a wide variety of innovative digital solutions for optimizing the project constraints of scope, time, cost, quality, and resources. Despite being one of the least digitized sectors, the AEC sector is currently ripe for adopting innovative digital solutions. It is observed that Building Information Modeling (BIM) has been rapidly adopted to tackle the ever-evolving challenges of mega infrastructure projects. This study investigates the challenges and enablers of utilizing an end-to-end BIM strategy for digital transformation of mega project delivery processes through a mega airport project case study, in order to contribute a solid strategic understanding in BIM implementation for mega infrastructure projects. The case study is followed with two-phased semi-structured interviews. Based on the findings, major challenges are sustaining continuous monitoring and controlling in the project execution, engineering complexity and aligning stakeholders’ BIM learning curves whereas strategic control mechanisms, incentivizing the virtual collaborative environment, and continuous digital delivery are major enablers.
Purpose Building information modeling (BIM) and lean construction are two practices that are developed in order to increase productivity, efficiency and quality in construction by implementing various procedures. However, the practical execution of both BIM and lean is mostly limited with the tasks performed in the office environments in the design phase. The purpose of this paper is to examine the benefit realizations in terms of lean interactions resulting from mobile BIM processes through a framework by focusing on digital transformations performed on the construction site. Design/methodology/approach This paper examines the benefit realizations in terms of lean interactions resulting from mobile BIM processes through a framework by focusing on digital transformations performed on the construction site. To describe the case, BIM project management processes during construction phase have been explained by a participatory research. With a comprehensive literature review, interactions between site BIM processes and lean principles have been defined and the case has been evaluated accordingly. Findings By focusing on the mobile BIM delivery of project information via tablets to construction site, it has been identified that through the use of technology enabled by BIM practices, lean construction principles are also simultaneously accomplished. This achievement is not only realized with technology but also with the strategic implementation and transformation of organization with the proper BIM practices. Research limitations/implications The research is focused on mobile BIM processes applied on-site to enhance traditional project management processes. With the findings of this paper, practitioners may identify research questions to resolve real-life implementation challenges. Practical implications This research will enlighten construction practitioners regarding site BIM application capabilities and lean achievements with the utilization of improved project management processes enabled by BIM. Originality/value Through the implementation of project management processes enabled by BIM practices on construction site, lean principles are achieved and bottlenecks are identified.
Purpose The purpose of this paper is to develop a solid understanding of how integrated building information modeling (BIM) is implemented in a mega project such as the (Istanbul Grand Airport IGA) construction project, which is the main case study in the research methodology. Design/methodology/approach The paper examines and identifies the lean efficiency gains achieved in the IGA project and highlights the synergies between BIM and lean concepts based on the facts and figures from the case study analysis. In complex projects, there is a vital need for a comprehensive approach that would enable successful managing of design and construction information via accurate modeling, collaboration and integration throughout the project lifecycles covering various disciplines. Findings The research findings in the paper make a significant impact in understanding the strategic perception for BIM as a new way of working methodology for the construction industry in Turkey, since the IGA project has become not only a key learning hub for the Turkish construction industry, but also a global landmark for digital construction and project delivery. In addition it proves the mutual synergies between BIM and lean practices. Originality/value The IGA project is a mega-scale airport construction project with features beyond building industry challenges, and it should be designed and constructed with tight deadlines and budgets and be operated afterwards in an effective and efficient way. Can lean and BIM help for timely and on-budget completion of the project and could they support the management of the airport facility after handover? The paper also discusses the lean and BIM implementation in the project in relation to the BIM Level 3 requirements.
