    Water as a basic need of all humans, their ultimate expectation is to have health and well-being life fulfilled with social and economic development through getting access to use of safe drinking water. Subsequently, providing adequate drinking water to all poor living areas has become a major challenge in developing countries like Sri Lanka. Community engagement in rural water supply (RWS) projects should become essential as the client and end-users are not involved in the project management process during a typical project. Therefore, the aim of the research is to investigate the factors which are significantly affect for effectiveness of Community Based Organisation (CBO) management in both client’s perspective and community perspective. A mixed approach was utilized for the study. A comprehensive literature review was intended to explore factors which are affecting for effectiveness of CBO management. Significant factors were observed through semi structured interviews based on Delphi technique to collect data on client’s perspective. Questionnaire survey was carried out based on close ended questionnaires to collect CBO perspective data. Data was analysed via content analysis to generate qualitative outcome while RII technique was utilised to analyse statistical data. Effective revenue, effective billing to collection ratio, effective CBOs’ managerial level, effective stakeholder relationship and monitoring quality of water were identified as both perspectives agreed factors. The most significant factor on CBO perspective was considered as effective CBOs’ managerial level while client perspective factors such as effective CBO involvement in operation and maintenance phase, development of CBO performance and relationship between National Water Supply and Drainage Board (NWS&DB) and CBOs was considered as most significant. Outcome of the study can be recommended to use as a tool before commencing the water supply project for aware about which factors are mostly assist to increase the effectiveness of CBO management.

    Strategies to improve the productivity of site level building contractors in Sri Lanka
    (Ceylon Institute of Builders, 2017-06) Dadallage, S; Abeynayake, M; Pilanawithana, N; Sandanayake, YG; Ramachandra, T; Gunatilake, S
    The construction industry is widely recognised as a laggard in terms of productivity improvement. Site level construction productivity is a major influential factor to reduce the overall productivity in the construction industry. The main reason behind this is the critical site level construction productivity problems faced by Sri Lankan contractors. Therefore, aim of the study is to identify the possible solutions to enhance the site level construction productivity of building contractors in Sri Lanka. Accordingly, a mixed approach was used for the research. Initially, an extensive literature review was carried out to identify the site level construction productivity influential factors which was followed by a preliminary survey to investigate the critical problems influencing the site level construction productivity of contractors in Sri Lanka. A questionnaire survey was carried out to identify the most critical site level problems faced by the building contractors in Sri Lanka. Finally, expert interviews were conducted to identify the possible solutions to enhance the site level construction productivity of building contractors. Findings revealed that the most critical site level problems include worker skills problems, worker motivation problems, unavailability of skilled labours, and material management problems on sites. Accordingly, introducing proper training programs, implementing incentive, rewards and appreciation schemes as per the workers’ performance, training unskilled workers, educating site workers on proper usage of materials are the possible solutions for the identified four most critical problems.
