Towards successful implementation of offsite construction in Sri Lanka: barriers and strategies

Abstract

The construction industry has significantly progressed by incorporating modern construction technologies. Offsite building is growing in popularity, yet it continues to face resistance from the built environment market and the construction industry. Offsite construction (OSC) is gaining recognition globally as a sustainable, efficient, and innovative alternative to traditional construction methods. In Sri Lanka, despite the evident benefits but OSC adoption remains limited due to several barriers. This research aims to investigate and identify strategies to overcome the barriers that hinder the successful implementation of OSC in building projects in Sri Lanka. Accordingly, the literature review highlighted the feasibility of OSC for the Sri Lankan construction industry and the advantages and barriers of OSC in the Sri Lankan context. Moreover, semi-structured expert interviews were conducted with 10 experts to gather data, and thematic analysis was used to analyze the collected interview data. Findings reveal that the primary barriers include high initial capital costs, lack of skilled labour, insufficient governmental support, limited public awareness, and a reliance on conventional construction practices. Additionally, logistical challenges, such as transporting prefabricated components, and the absence of standardized design codes further constrain OSC implementation. Despite these obstacles, the study emphasizes the transformative 5 potential strategies proposed for promoting the adoption of OSC in building projects in Sri Lanka. This strategy strives to empower Sri Lanka towards a more innovative, productive, and sustainable construction industry
