| Abstract | Nepal has favorable condition to develop numerous hydropower plants yet it is facing eighteen hour load shedding per day during dry season. Traditional approach adopted in Nepal for hydropower construction involves many problems such as design changes, reworks, poor safety practices, time delays, cost overruns, disputes, claims which hampers constructability of the project. In this context, it is worthwhile to conduct research which focuses on investigation of the degree of importance and level of application of constructability concepts and identifying the major barriers hindering effective implementation of those concepts. The findings would be appropriate for the preparation of baseline required in constructability improvement guideline for hydropower construction in Nepal. Thirty-six constructability concepts and forty-nine implementation barriers related to hydropower construction in Nepal were selected for detail study after extensive literature review and expert verification. Through questionnaire survey, opinions on those constructability concepts and implementation barriers were collected from fifty-three managers/engineers associated with hydropower developers, consulting firms and construction companies involved in hydropower construction in Nepal. The quantitative data gathered were then analyzed using various statistical techniques to conclude and recommend further studies. The result of this study revealed that six constructability concepts were accepted as very important concepts by overall respondents and the remaining concepts were considered to be important. To the contrary, none of the concepts are being highly applied in hydropower construction in Nepal. Further, ten major constructability implementation barriers were identified and grouped as ineffective communication and coordination, socio-political influences, and insufficient resources using factor analysis. The effective implementation of constructability concepts in hydropower projects in Nepal can be attained by developing guidelines for the application of those concepts. For preparation of the guidelines the concepts identified by the study need to be verified with hydropower projects of various sizes and different financing models and detail procedures for applying those concepts should be documented. Also, identification of specific barriers for each constructability concept is necessary in milieu of developing guidelines for hydropower projects. |
