Abstract

Purpose

The increasing urbanization of the built environment has bolstered the need to promote green Building Information Modeling (BIM) initiative in new construction projects and the rehabilitation of old premises. This study aims to explore and examine the key benefits of the implementation of BIM and sustainability practices in the built environment.

Design/methodology/approach

The study gathered the worldwide perceptions of 220 survey participants from 21 countries which were analyzed using descriptive and inferential analytical methods. The identified individual benefits of green BIM were further categorized into their underlying clusters using factor analysis.

Findings

The key benefits are related to enhancing project efficiency and productivity, ensuring real-time sustainable design and multi-design alternatives, facilitating the selection of sustainable materials and components, together with reducing material wastage and project’s environmental impact, among others. The study analyzed and compared the perceptions of the diverse groups of the respondents as well.

Practical implications

Effective blueprints and insightful recommendations for enhancing the various stakeholders’ capacities to implement green BIM in their construction projects were put forward to achieve the aim of sustainable smart urbanization.

Originality/value

The study identified salient benefits of the adoption of BIM and sustainability practices. The proper integration of these concepts and the execution of the recommended useful strategies by construction stakeholders, policymakers and local authorities will enable the built environment to reap the gains of its implementation.

Abstract

Purpose

This paper aims to assess the level of awareness of quantity surveyors in material management and their key roles in waste minimization during the post-contract stage of the project with a view of achieving value for money in their roles.

Design/methodology/approach

This involves administering a questionnaire survey to registered members of the Nigerian Institute of Quantity Surveyors, the only recognized professional body of quantity surveyors in Nigeria, within Lagos state. The empirical questionnaire survey succeeds a literature review that isolates the key strategies used by quantity surveyors in material management and waste minimization at the post-contract stage. The validity of the questionnaire was carried out by two experienced construction industry researchers and three experienced professional quantity surveyors to ensure that the questionnaire was not ambiguous and that it consists of the right questions in tandem with the research. The respondents were grouped into consultant’s QS and contractor’s QS.

Findings

Key roles of quantity surveyors during the material management process are proper material storage, and material inventory and accounting are the most important material management and waste minimization practices during the institute stage. It revealed that there is a lack of material waste documentation practices during the construction stage. In addition, there is no statistically significant difference in the responses of the two groups. This may be because there is no clear compartmentalization between the practices of the two groups. In addition, these two groups had the same education training, as there is no difference between the educational training of the consultant’s QS and contractor’s QS.

Originality/value

This study assessed the quantity surveyors’ roles with regard to material management and waste minimization. It would add to the scanty research work in this area. The study has also successfully revealed the strategies that are to be adopted by the quantity surveyors to achieve value for money during the post-contract stage.
