Abstract
Purpose
Design cost overrun is one of the prominent factor that can impact the sustainable delivery of the project. It can be encountered due to a lack of information flow, design variation, etc. thereby impacting the project budget, waste generation and schedule. An overarching impact of this is witnessed in the sustainability dimensions of the project, mainly in terms of economic and environmental aspects. This work, therefore, aims to assess the implications of a technological process, in the form of building information modelling (BIM), that can smoothen the design process and mitigate the risks, thus impacting the sustainability of the project holistically.
Design/methodology/approach
The identified design risks in construction projects from the literature were initially analysed using a fuzzy inference system (FIS). This was followed by the focus group discussion with the project experts to understand the role of BIM in mitigating the project risks and, in turn, fulfilling the sustainability dimensions.
Findings
The FIS-based risk assessment found seven risks under the intolerable category for which the BIM functionalities associated with the common data environment (CDE), data storage and exchange and improved project visualization were studied as mitigation approaches. The obtained benefits were then subsequently corroborated with the achievement of three sustainability dimensions.
Research limitations/implications
The conducted study strengthens the argument for the adoption of technological tools in the construction industry as they can serve multifaceted advantages. This has been shown through the use of BIM in risk mitigation, which inherently impacts project sustainability holistically.
Originality/value
The impact of BIM on all three dimensions of sustainability, i.e. social, economic and environmental, through its use in the mitigation of critical risks was one of the important findings. It presented a different picture as opposed to other studies that have mainly been dominated by the use of BIM to achieve environmental sustainability.

Abstract
Purpose
Stakeholder assessment is based on attributes possessed by stakeholders, making the process heavily reliant on evaluating attribute weights. The present assessment methods are based on Analytical Hierarchy Process, Analytical Network Process, and pairwise comparisons that heavily rely on decision-makers’ skills and knowledge. An objective evaluation of attribute weight needs to be done to overcome this challenge.
Design/methodology/approach
A Multi Criteria Decision Making (MCDM) based approach, through the combined use of Criteria Importance Through Intercriteria Correlation (CRITIC) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods has been incorporated to objectively evaluate the weights of the stakeholder attributes and their ranking with a specific focus on construction megaprojects. Five stakeholder attributes and twelve commonly associated stakeholders with megaprojects were considered to achieve this.
Findings
The new model presented power, durability and legitimacy as three important stakeholder attributes, further used to determine stakeholder importance. The client, contractor and project manager were identified as the top three internal stakeholders, and customers, local community and utility service providers as three crucial external stakeholders.
Research limitations/implications
The findings from the proposed method provide the practitioners with updated information about the attributes they need to look into when planning stakeholder involvement and management. Further, it also leads them to the established framework for the provided stakeholder ranking when planning their management strategies.
Originality/value
The use of CRITIC method allowed to address the possibility of any correlation between the attributes in their weight determination. This was one of the advantages as co-relation between the attributes during their weight determination has not been addressed in previous methods.
