Publication Open Access 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.NConstruction 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.Publication Embargo Issues and Challenges faced by Students from Single-Parent Households in Their Academic Performance at Senior Secondary Level.(Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Perera, L. I. SAn increase in single-Parent household is noticeable in the contemporary society. Academic performance of the students living in single-parent households is affected negatively at large. Therefore, this study aims to discover the issues and challenges that single-parented students face in their academic performance at the senior secondary level. A stratified random sampling method was used and the sample size was 100 senior secondary students from singleparent households from the Moratuwa Educational Division. Three self-developed questionnaires were administered to collect data. Secondary data was collected through test scores and school-based assessments. Descriptive statistics such as frequency counts, percentage and standard deviation were computed. The main conclusion of the study is that the issues and challenges that singleparented senior secondary students face have adverse effects on their academic performance. If these issues and challenges are addressed accurately and deliberately, the senior secondary students' academic performance can be improved. This study recommends that groundlevel stakeholders like school administration, teachers, welfare societies, and educational counsellors pay their attention and help singleparents and their children to cope with their situations and enhance their academic performance.
