An integrated approach of Lean-Green construction: Sri Lankan perspective

Abstract

Purpose

Construction industry hesitates to associate Green concepts on building projects mainly due to its high initial investment cost. Even if it is economical in the long run, often the benefits are suppressed with the costs generated through non-value-adding activities in the construction process. Lean construction principles have proved to eliminate such waste while enhancing the construction process. Thus, the purpose of this paper is to explore the applicability of the integration of Lean and Green concepts in the construction industry.

Design/methodology/approach

The fundamental principles of both Lean and Green construction were evaluated through an extensive literature survey. A qualitative approach was adopted, and thus, based on the literature findings, expert interviews were conducted with professionals having experience in both Green and Lean concepts. Furthermore, the findings were validated through experts to analyse the adaptability of the integration. Content analysis technique was utilised with NVivo software programme to analyse the findings.

Findings

The integration of the Green concept was found to alter the traditional application of Lean concept, considering the social and environmental aspects without limiting to economic considerations. The study revealed that the perception of the Sri Lankan stakeholders towards the application of integrated Lean-Green concept is focussed on a positive direction. As a result, the identified enablers to implementing the integrated concept supersede the barriers by confirming the appropriateness of the application in the local construction industry.

Originality/value

A framework was developed through the findings to guide the implementation of integrated Lean-Green application in Sri Lankan context.
