    Strategic implementation of PPP for small-scale infrastructure in Sri Lanka: a comparative analysis of alternative PPP models
    (Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Guruge, K; Coomasaru, P; Weeraman, C
    This study aims to provide a thorough comparison of Private Finance Initiative (PFI), Build-Operate-Transfer (BOT), and Joint Venture (JV) models for Small-Scale Infrastructure Development (SSID) in Sri Lanka and devise innovative, tailored recommendations to maximise efficiency, effectiveness, and compatibility. Employing a mixed-methods approach, the research systematically examines the key features, benefits, and limitations of PFI, BOT, and JV models in the context of SSID. A compatibility assessment is conducted, focusing on financing approaches, stakeholder engagement, and other critical success factors. The findings reveal that the BOT and JV models are superior to the PFI model due to their balanced stakeholder engagement, risk sharing, and alignment with critical success factors. Based on these insights, the study formulates novel, customised recommendations for optimising the selected model's efficiency, effectiveness, and compatibility with SSID in Sri Lanka, with the aim of informing policy and practice. Furthermore, the study highlights the need for future research exploring alternative financing models and emerging technologies in SSID, opening new avenues for innovative approaches to infrastructure development in Sri Lanka. In conclusion, this comprehensive comparison offers valuable guidance for academics, industry professionals, and policymakers seeking to enhance small-scale infrastructure development in Sri Lanka, emphasising the importance of selecting the most suitable financing model.

    AN IOT-BASED ELECTRICAL AND ELECTRONIC APPLIANCE MANAGEMENT SYSTEM FOR SRI LANKAN RESIDENTIAL BUILDINGS
    (Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Liyanage, D.L.C.P; Anuradha, I.G.N; Kumarathunga, J.U; Kalugala, C; Samarakoon Arachchige, D.S
    Sri Lankan household energy consumption was accounted for around 34% of national energy consumption in 2017, and residential applications were accounted for 36% of national energy waste in 2018. Therefore, reducing the energy wastage in the household environment is essential. Researchers from all around the world are working to develop IoT-based solutions to reduce energy wastage, but there are certain challenges in adapting them to the local context as those techniques were developed for foreign domestic usage. As a result, it is crucial to come up with IoT-based solutions which are appropriate for the local environment to assist the reduction. Therefore, this article examines the importance and feasibility of adopting IoT-based electrical and electronic device control systems for household use in Sri Lankan environments. Further, a mobile application was developed to monitor and control the system, which was installed for a residential building after an analysis of the domestic requirements. This system may simply fix into an existing building, making it a cost-effective application for reducing energy wastage in developing countries.

    POTENTIAL IMPACTS OF BLOCKCHAIN TECHNOLOGY IMPLEMENTATION ON CONSTRUCTION CONTRACT MANAGEMENT IN SRI LANKA
    (Construction Contract Management, 2023-07-21) Karunaratne, B.C.T.M.; Abeynayake, D.N.
    The construction contract is the mainstay for the ascendancy of the construction project requiring proper contract management. The Sri Lankan construction industry has many complications associated with contract management. Blockchain, as a decentralised transaction and data management technology, can potentially address the issues related to contract management amidst the impediments to effective implementation. However, blockchain technology adaptation in the Sri Lankan construction industry lacks evidence, even though other sectors, for example, banking and agriculture, are with the initial implementation. Hence, this research aimed to identify the potential impacts of implementing blockchain technology in construction contract management in Sri Lanka. A literature review was conducted to identify the concept of blockchain technology, its applications and its benefits. A qualitative survey strategy was adopted, and data were collected via semi-structured interviews in two phases; Phase I with ICT and finance industry experts and Phase II with construction contract experts. Samples were selected purposively through snowball sampling. The data analysis revealed that the awareness and use of blockchain technology in Sri Lanka are relatively low. However, Sri Lanka has the potential to adopt Blockchain in different fields, depending on their capabilities. Furthermore, the study found associated positive impacts of Blockchain, e.g., avoiding complex procedures, providing transparency, no ambiguities, no human errors and reducing political influence to mitigate contract management issues. Besides, Blockchain may negatively impact due to, e.g., high initial and maintenance costs, lack of knowledge and expertise, unavailability of rules and regulations, and reluctance to change those need mitigations.

    A STUDY ON THE PHYSICAL AND MENTAL HEALTH ISSUES TO THE NEIGHBOURING RESIDENCES DUE TO THE CONSTRUCTION PROJECTS IN SRI LANKA
    (Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Arjuna, M.P.; Edirisinghe, V.; Manoharan, K.; Herath, S.S.
    This study investigates the physical and mental health issues experienced by neighbouring residences as a result of construction projects in Sri Lanka. Specifically, it examines the impact of these projects on respiratory distress, hearing impairments, traffic congestion, lack of landscape, and flooding conditions. Additionally, the study explores the psychological effects on residents and emphasises the importance of health and safety measures in project management. Data collection involved conducting interviews with project managers, site safety officers, and a male nurse from three selected construction sites, followed by a questionnaire survey administered to 30 neighbouring residents. The study provides recommendations to mitigate adverse impacts, raise community awareness, and promote environmentally friendly practices in the construction industry. The findings enhance understanding of the health challenges faced by neighbouring residents and offer insights to policymakers and project managers to improve the well-being of affected communities.

    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
