    Lean integrated circular economy in the Sri Lankan construction industry: a qualitative Delphi study
    (Ceylon Institute of Builders, 2025) Vijayakumar, H; Ranadewa K.A.T.O; Weerakoon, P; Weerakoon, P; Jayanetti J.K.D.D.T
    The construction industry is known for its significant environmental impact and waste generation. To address this issue, the concept of Circular Economy (CE) has emerged, aiming to minimise waste and maximise resource utilisation. However, there are several barriers which impede the implementation of the CE concept in the construction industry. Therefore, this research aims to incorporate the lean concept to overcome the barriers of CE implementation in the construction industry. Therefore, this research develops a framework for a lean-enabled CE in the construction industry. The qualitative approach is used for this paper, and the Delphi technique was adopted. Purposive sampling was used to select the experts for the study, and data were analysed through manual content analysis. The findings revealed 10 benefits from CE and 12 benefits from Lean were identified, along with 8 benefits of CE and Lean integration. Furthermore, 19 barriers were identified towards this integration, and 12 strategies were identified to overcome these barriers. This study also provides a comprehensive mapping between CE and Lean implementation benefits, their integration benefits and barriers, and strategies. In addition, integrating lean and CE for the construction industry can lead to many significant benefits, such as cost savings, improved environmental performance, and enhanced stakeholder engagement.

    THE APPLICABILITY OF CARBON EMISSION ESTIMATION WITH BIM ENVIRONMENT: SRI LANKAN CONTEXT
    (Ceylon Institute of Builders, 2025) Perera D.A.M.V; Allis C; Perera B.K.C; Lokuge A
    The global construction industry is increasingly adopting sustainable practices and advanced technologies to enhance efficiency and reduce environmental impacts. Within this context, managing carbon emissions has emerged as a critical component of sustainable development, with Building Information Modelling (BIM) serving as a pivotal tool in this pursuit. While developed countries have already integrated BIM and carbon emission estimates, there is a notable opportunity for similar advancements in developing countries, potentially leading to significant progress within the industry. Hence, this paper aims to explore the applicability of implementing BIM for carbon emission estimations in the Sri Lankan construction industry. A comprehensive review of existing literature identified the importance of carbon emission simulations, BIM implementation strategies and estimation procedures in other countries. Further, this research involved a survey to assess the familiarity and experience levels of construction professionals with BIM tools for carbon emission estimations in Sri Lanka. Findings from the research point to Autodesk Insight as the primary software tool used within the industry. While the industry demonstrates an awareness of these processes, its progress is hampered by a lack of experience in using these technologies for carbon emission estimation scenarios and the absence of crucial databases such as Environmental Product Declarations. The study recommends enhancing industry capacity through targeted training and the adoption of advanced tools. It also encourages further research to assess the compatibility of BIM technologies in the local context, aiming to bridge the gap and drive sustainable transformation in Sri Lanka’s construction sector.

    TOWARDS SUCCESSFUL IMPLEMENTATION OF OFFSITE CONSTRUCTION IN SRI LANKA: BARRIERS AND STRATEGIES
    (Ceylon Institute of Builders, 2025) Manodya L.P.T.; Bandara R.P.H.S; Buddhini P.H.Y
    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

    IMPACT OF ECONOMIC CRISIS ON EMPLOYEES OF CONTRACTORS’ ORGANISATIONS IN THE SRI LANKAN CONSTRUCTION INDUSTRY
    (Ceylon Institute of Builders - Sri Lanka, 2023-07-21) De Silva, S.S.; Wijekoon, W.M.C.L.K.; Kalugala, C
    The construction industry contributes more than 6% of the GDP of the Sri Lankan economy, employing workers at different levels of the value chain. The economic crisis in the country from 2019-2022 has had a significant impact on contractors’ organisations in the Sri Lankan construction industry, resulting in job losses, pay cuts, and reduced working hours. Hence this study aims to investigate the impact of the economic crisis on the employees of contractors’ organisations in the Sri Lankan construction industry, the most affected level of employees, and propose strategies to minimise the impact on the most affected level of employees. This study has been done using the mixed-method approach. Thirty-three (33) employees participated in a questionnaire survey and seven (7) managerial-level professionals were interviewed who are currently engaged in construction projects. This study has explored the levels of employees including technical, supervisory, and similar levels, professional level, administration, and managerial level. Further, this study provides the strategies adopted by the employees and the contractors to overcome the impact of the crisis, including measures to enhance productivity, cost reduction strategies, and access to financial support. The findings of the study will provide insights into the impact of the economic crisis on the construction industry in Sri Lanka and inform policy recommendations to support affected workers and ensure the long-term sustainability of the industry in a resilient way

    Modelling the Implications of Delayed Payments on Contractors’ Cashflows on Infrastructure Projects
    (Salehan Institute of Higher Education, 2023-01-01) Chadee, A; Ali, H; Gallage, S; Rathnayake, U
    The consideration of payments to contractors is not only a legal obligation but a necessity for assuring the continuity and completion of a construction project. However, consistent payments to facilitate project cash flows are uncommon in the construction industry. Within the context of a small island developing state, this paper aims to uncover leading risks factors contributing to implications of delayed payments, on contractors’ cash flows and uncover causalities and effects on relationships among these factors. A two-tiered quantitative approach was adopted. Firstly, a compiled list of delay factors was collated from the literature review. Semi-structured interviews were conducted with experienced construction professionals to determine the factors’ relevance and applicability in Trinidad and Tobago. A closed-ended survey questionnaire was subsequently developed and administered to primary construction stakeholders. Secondly, the responses obtained were collated, validated, and ranked using the relative importance index. A confirmatory factor analysis (CFA) was carried out using SPSS, and thereafter, SPSS Amos was used to determine the best-fit Structural Equation Model (SEM). The results strongly indicate that the issue of delayed payments is very prevalent within public sector projects. Unstable political climates and the delay in employers’ issuance of variation orders were found to be the main causes of delayed payments within the industry. Delays in sub-contractor and supplier payments as well as an increase in the contractor’s debt were the leading effects of delayed payments on the contractor’s cash flows. Based on these findings, a risk response framework was outlined to assist small to medium-contracting enterprises to cope with payment delays, both locally and internationally. This research contributes to the advancement of construction management knowledge by informing construction professionals and policy makers of the implications of delaying approved payments, the consequential causes and effects, and a risk response technique to mitigate the negative effects on contractors’ cash flows.

    Factors influencing the timely completion of construction projects in Sri Lanka
    (Public Library of Science, 2022-12-15) Abeysinghe, N; Jayathilaka, R
    Timely completion is a crucial factor for the success of a construction project, especially in the Sri Lankan context. This study aims to identify the most influential factors that affect the timely completion of construction projects in Sri Lanka. Thirty-nine factors were identified through a comprehensive literature review and experts’ opinions. A questionnaire incorporating the 39 project delay factors was distributed among 163 Civil Engineers, and responses were obtained. Random sampling method was adopted to select the sample. The Relative Importance Index (RII) analysed and ranked the project delay factors. The top ranked significant project delay factors were identified as shortage of skilled subcontractors/suppliers, shortage of labourers (Skilled, semi-skilled, unskilled), financial difficulties of contractors, delay in delivering materials to the site, and Covid-19 pandemic situation. According to the main three respondent types, i.e., clients/owners, contractors and consultants, the contractor related factors was the key group among others that delay a construction project. The scientific value of the study includes assisting the Sri Lankan construction industry to identify the factors affecting the timely completion of construction projects, and developing mitigation methods and strategies. Also, the stakeholders could duly schedule the construction work by identifying areas that need more attention. The contribution of this study would assist stakeholders to adopt a proactive approach by identifying mistakes on their part and minimising potential issues that lead to construction project delays in Sri Lanka.
