Identifying and prioritizing the benefits of integrating BIM and sustainability practices in construction projects : a Delphi survey of international experts

Implementation of an interoperable process to optimise design and construction phases of a residential building: A BIM Pilot Project

The construction industry is beginning to utilize building information modeling (BIM), benefiting from the improved visualization and productivity, better coordination of construction drawings, building documents that contain embedded links to virtual information, faster delivery, and lower costs. However, construction companies often find it challenging to reorganize their company’s organizational structure to take full advantage of these benefits of BIM adoption and implementation. This study explores contractors’ transformation strategies that will enable them to successfully adopt and implement BIM for major construction projects. In-depth case studies from large contractors capture the benefits of BIM implementation, the appropriate organizational structure, the training and education program, the cost related to BIM implementation, including software and hardware investment, the relationship with other stakeholders, and the future recommendations to implement BIM for their construction proje...

Contractors' Transformation Strategies for Adopting Building Information Modeling

Architectural, Engineering and Construction (AEC) industry. There have been many changes in the past few years in the use of BIM and how to implement BIM in the AEC Industry. The purpose of this research is to examine the current status of BIM in the Middle East by exploring the extent of adoption of BIM among stakeholders in the AEC industry in this region. To this end surveys were sent out to 297 and empirical statistics have been applied. The respondents acknowledged they were aware of the benefits of BIM in terms of it being a more effective method for designing and managing construction projects by supporting collaboration, improving the quality of the design by providing the ability to closely visualize designs in 3D and rendered forms and providing a platform which would facilitate the sharing of information relevant for design, construction and maintenance of buildings over their entire lifecycle. However, only 20% of AEC organizations in the Middle East are using BIM or are in the process of adopting BIM, with more professionals beginning to adopt BIM although most professionals within this region still look at BIM just as an advanced AutoCAD tool. Raising awareness related to the benefits of BIM and increasing training opportunities in the Middle East are necessary in order to allow all stakeholders to benefit substantially from BIM.

An investigation into the implementation of building information modeling in the Middle East

Early collaboration is crucial if the final design is to be clash-free, and automation processes through Building Information Modelling (BIM) have the capacity to reduce clashes through 3D design coordination. Yet, current design practices are still dependent on clash detection and contemporary literature presents several reasons for this. This paper investigates the root causes of clashes with respect to achieving “clash avoidance” as proposed in PAS 1192-2 design phase specifications for BIM in the UK. Empirical data from BIM coordinators around the world was collected and analyzed using explanatory sequential mixed-methods. It was found that: (i) isolated working was the prime cause of high occurrences of clashes linked to mechanical, electrical and plumbing (MEP) 3D BIM systems; (ii) there is a link between non-BIM specific training (or the professional qualifications) of design practitioners with the high incidence of clashes; and (iii) the current structure of cloud-based common data environments (CDEs) does not facilitate clash avoidance and in fact, encourages isolated working in the early design stage by creating “digital information silos”. A conceptual framework for an open work in progress (OWIP) has been proposed to address this problem. These findings point to the need for more transparency during collaboration through CDE where designers from multidisciplinary backgrounds can engage in concurrent co-creation. This transparent and inclusive process could have consequences on how future architectural, engineering and construction (AEC) professionals are trained.

Clash detection or clash avoidance? An investigation into coordination problems in 3D BIM

Recently more and more Public Sectors have been paying close attention to save cost and, at the same time, improve efficiency. Usually, the Construction Industry has a relevant annual turnover, which represents an important part of the GDP for most of the EU countries and concerns in a large part the Public Sector. Thus, some Public Clients, such as UK, are adopting new strategies in order to improve the current situation. One of these strategies is Building Information Modelling (BIM), which forces all the parties involved in the process to adopt a collaborative approach reducing inefficiencies. Moreover, also the European Parliament is going to encourage the BIM adoption to ‘modernise the procurement process and ensure greater efficiencies’. The EU Directive will be an important push to reform the EU Members’ Public Construction Procurement. The aim of this M. Sc. Thesis is to analyse the possible implementation of BIM within the Public Procurement, especially how Model Checking can be applied within Tendering to verify the compliance between the Client’s requirements and the bid’s contents. The first part presents both the most widespread Public Procurement Methods, such as Design-Bid-Build (DBB), Design-Build (DB), Construction Management (CM), Design-Build-Operate (DBO) and Design-Build-Finance-Operate (DBFO), as well as innovative kinds of Procurement Procedures, such as Integrated Project Delivery (IPD), Project Alliancing (PA), Cost Led Procurement (CLP), Integrated Project Insurance (IPI), Two Stage Open Book and Early BIM Partnering (EBP). A paragraph is dedicated to the drivers and the barriers of e-Procurement, which should be part of the Public Procurement strategy. Later, the main issues related to BIM are shown, such as current BIM Authorised Uses and Permitted Purposes, Interoperability and OpenBIM, along with BIM implementation in Public Sector of several countries (Singapore, USA, Finland, UK, Norway, Denmark, Netherlands, South Korea, Hong Kong, Australia, New Zealand, Iceland, Estonia, Sweden, Germany, China, Ireland, Taiwan and Italy) and the relation between e-Procurement and BIM. Additionally, the principal possibilities and challenges dealing with BIM adoption are presented. The following chapter is dedicated to the investigation of the possible BIM implementation in Tendering. Even if integrated procedures, such as IPD, seem to be the most suitable with BIM, a discussion of the BIM role in DBB and DB or Design Competitions is carried out, showing the main Client’s requirements, benefits for Bidders and Clients, together with limitations and possibilities. Thereafter, a paragraph illustrates Model Checking in the evaluation of design proposals. First, a short description of the main commercial software, which can support BIM-based tendering (such as Solibri Model Checker (SMC), EDM Model Server, dRofus, Affinity, dProfiler, Autodesk NavisWorks, Tekla BIMsight, Bentley Projectwise Navigator, Riuska, Autodesk Ecotect, EasyBIM, Vico Cost Planner and Mitchell Brandtman) is provided. Later, a list of the most common operations, which nowadays
