This paper presents a comparative study of commercially available BIM-based estimating software, and an investigation of the changes in work practices and workflows incurred by the adoption of such software by a construction company. Due to the fragmentation of the construction industry and the linearity of the design process, cost estimating is typically performed at a time when the conceptual design is quite advanced or even completed, which is much too late in the design process to help the different stakeholders make informed decisions. Performing value engineering and cost estimation from the beginning of the design process would potentially enable a faster and more cost-effective project delivery process, higher quality buildings, and increased control and predictability for the owner. This research examines the changes in work practices and work flows within a construction company as they move towards adopting Building information Model (BIM) estimating process. To conduct this research, we: (1) tested several BIM-based cost estimating software tools to support different phases of design, (2) evaluated the benefits and challenges of working with this software, and (3) analyzed the work practices and workflows of a BIM-based estimating process within the firm. Finally, we propose a multi-stage technology adoption scenario.

In recent decades, municipalities around the world have been developing community policies and seeking to apply them in their cities. They use methods for exchanging information and opinions on decisions, policies, plans and strategies and involve and consult with the community and stakeholders in all aspects of the decision-making process. The application of methods for thoughtful planning has become the goal of policy makers to improve the lives of citizens and stop the expansion of the city into the countryside. The aim of this article is to integrate the notion of sustainability into a methodological approach, taking into account the actors involved in the decision-making phases, the objectives, and the local indicators in an urban redevelopment project (brownfield). Our approach is based on an analysis of 21 articles and on a transversal and cross-cutting view of the interdisciplinary themes of sustainable development by inserting the main actors into decision-making in urban projects and by selecting local indicators. We put in place a methodological approach for the evaluation of urban projects that takes into account local expectations. The goal is to identify and classify the elements that are needed for decision making, including the indicators related to environmental and socio-economic components, in order to develop an effective evaluation tool. This research contributes to the knowledge of project evaluation tools in the specific context of a city.

Purpose: Given the ongoing digital transformation, building information modeling (BIM) has great potential to create a collaborative environment in the whole lifecycle of the built asset, from inception to decommissioning. The paper aims to discuss this issue. Design/methodology/approach: This paper relates current developments in Québec with regard to the use of BIM for asset management (AM). The steps taken by three public organizations to develop their capabilities and take advantage of new possibilities are presented. The main methodological approach is based on participant observation, through case studies complemented by a questionnaire. Findings: This paper reports on results and analysis of an important module of a broader research project on the impact of new technologies and collaborative methods for projects and AM. The results of this first research module points to the importance of using pilot projects to develop a continuous improvement approach, where feedback loops from projects support the development of AM capabilities and culture. Another important finding is the importance of sharing experience for the three public organizations involved. Originality/value: The main contributions of this paper are to document this overarching research program and to gain deeper insights by reflexively considering the steps taken and the ones ahead for the quest to enhance the transfer of information for built assets at the end of projects to the operations and maintenance phase and to use BIM for operation.

Building Information Modelling (BIM) was introduced in the Architecture, Engineering and Construction (AEC) industry as a shared information platform that aims to improve productivity through better collaboration. The assumption is that a virtual integration of information among project stakeholders would reduce the issues around the fragmented nature of the processes that still prevail in the construction field. This paper aims to highlight the sources of waste in the information flows between an architecture firm, a Mechanical, Electrical and Plumbing (MEP) engineering firm, a general contractor (GC) and a MEP subcontractor (SC) in a BIM project – an aspect of waste little covered in the Lean literature. The focus is on the MEP process from early design to the final product. This research contributes to the identification of the main barriers to information flow, including the conflicts and waste sources that emerge from using BIM, as well as to the identification of emerging successes. Moreover, the findings offer practical implications by providing a visual of the patterns emerging from the use of BIM. Finally, by providing potential waste reduction strategies such as Value Stream Mapping (VSM) this work allows construction actors to identify and reduce sources of waste in their processes.

Purpose: The purpose of this paper is to investigate a case of collective sensemaking about the project success of the multifunctional amphitheater of Quebec (Canada). Design/methodology/approach: For this explorative and qualitative research, the authors started from the post-mortem document and complemented their comprehension with six semi-structured interviews with the main project actors and other public documents regarding this project. Findings: According to the respondents, the main success factors of this project can be attributed to: a clear governance structure; proven project management and construction methods; the use of emerging collaborative practices in construction (such as building information modeling (BIM) and lean construction); an adapted policy for procurement; as well as a code of values and ethics shared by all stakeholders. Originality/value: The sensemaking perspective has been scarcely mobilized in project management studies, emerging from a constructivist view of reality and being sensitive about material-discursive practices. This exploratory study explores a case of collective sensemaking of a major project success and suggests avenues for major and megaprojects research. Lessons learned and implications for practice are also outlined. The conclusion allows a synthesis and an opening to consider how practitioners and researchers can build on this (and other successful) case(s) for future projects and research.

Universities are facing many challenges to their efforts to introduce building information modeling (BIM) in engineering education. Many research efforts have been dedicated to the subject and addressed some specific aspects of the issue. Thus, there is no comprehensive framework to provide decision-makers with practical and neutral guidelines. The framework proposed in this paper identifies the main challenges to address. A case study from a Canadian engineering school is used to evaluate and to validate the proposed framework, and to illustrate the challenges. The strategy of integrating BIM in engineering education should be based on the specific skills the students are expected to acquire. It is then possible to define the appropriate teaching approaches. An effective implementation strategy should be gradual to progressively raise community awareness, learn from mistakes, and identify best practices. A particular emphasis should be placed on the needs of the local industry.
