    Whole Life Costing Awareness and Implementation Challenges in the Sri Lankan Construction Industry
    (SLIIT, Faculty of Engineering, 2024-03) Jayasinghe, D.I.C; Abeynayake, D.N
    Construction industry is highly demanding, especially with regard to the project cost as a significant aspect. However, more informed cost advice can be produced considering the project’s life cycle that begins with the conception and ends with its disposal instead of using a conventional initial capital cost basis. Thus, Whole Life Costing (WLC) and Life Cycle Costing (LCC) concepts are essential. Though many LCC research studies exist, WLC studies are minimal in the Sri Lankan construction industry context. Therefore, this study aims to explore WLC awareness and implementation challenges in the Sri Lankan construction industry. A literature review was conducted to search for the concepts. Empirical data were gathered using questionnaires by implementing a quantitative survey strategy. Findings depict that the awareness of WLC in the Sri Lankan construction industry is poor, preventing its benefits. Moreover, this research identified difficulty in identifying includes and excludes for calculating WLC, lack of details at early stages, lack of awareness of WLC benefits, lack of understanding of WLC tools, lack of reliable data and lack of expertise/knowledge on WLC as the primary challenges in implementing WLC in the Sri Lankan construction industry. Therefore, these challenges must be mitigated for the beneficial WLC implementation in the Sri Lankan construction industry while enhancing awareness and knowledge of the WLC concept among professionals, especially quantity surveyors, to facilitate responsible initiation of WLC practices in the Sri Lankan construction industry.

    Off-Grid Wind-Solar Hybrid Energy System for Analaitivu Island in Sri Lanka
    (SLIIT, Faculty of Engineering, 2023-10) Liyanagama, N; Ravindra, D; Bopitiya, P; Guruvita, K
    The objective of this project is to implement an off-grid wind-solar hybrid energy system with a battery bank system for Analaitivu island in Sri Lanka, which has no connection to the main grid. The hybrid model is developed by analyzing the wind-solar weather pattern of the island to fulfill the energy demand by choosing the ideal combination of solar cells and wind generators

    Strategies Used by the Sri Lankan Construction Industry to Overcome the Challenges Posed by the Covid-19
    (SLIIT, Faculty of Engineering, 2023-03-02) Fernando, P; Gunarathna, N
    The global outbreak of the COVID-19 pandemic has thrown the world's political, social, economic, religious, and financial structures into disarray. COVID-19 has a broad range of effects on numerous industries, including construction. Sri Lanka as a developing country is also affected by the pandemic and many sectors of the Sri Lankan economy such as construction, education, tourism, imports and exports, agriculture, and health etc are experiencing negative consequences of the pandemic, Construction industry as one of the key sectors of the economy was also severely affected by the COVID-19 global pandemic in various ways. Construction companies and government institutes are taking action to face these challenges. This study describes how COVID-19 impacts the local construction industry throughout the construction process. Furthermore, the impact was evaluated with regard to several aspects namely, financial, human resources, supply chain and logistics, legal, and completion and handover of the project. The strategies which are used by the construction industry participants to face the challenges of the pandemic are also discussed. A mixed research approach was used in the study and questionnaires which comprised of both qualitative and quantitative questions were used as a data collection tool. This research revealed new knowledge about the construction industry in relation to the COVID-19 pandemic. The study's most important finding was that the spread of the virus influenced the entire construction process. The pandemic had a major impact on the construction stage as well as the human resources aspect of the industry.
