THESIS ABSTRACT

Abstract

Building Information Modelling (BIM) is an integrated solution withbetter project visualization, coordination, information management, cost control and lifecycle asset management. Although BIM is widely used in many developed countries, the use of BIM in Nepal is still at an early stage. Especially in government-led construction projects challenges like technical, organizational, financial and policy-related challenges affects the use of BIM. This study aims to explore the challenges in the adoption of BIM in the planning and design, construction, operation and maintenance phases of government building projects in Nepal. Also it aims to identify the potential benifits of BIM and strategy to enhancing project performance and asset management with the adoption of BIM. A mixed-method approach was adopted, combining quantitative and qualitative methods. Primary data were gathered using structured questionnaire survey to technical professionals working on government building projects and Key Informant Interviews (KII) with BIM experts. The results indicate that the most important challenges in the planning and design phase are the limited availability of BIM-capable designers and consultants and the lack of awareness and knowledge of BIM. The major hurdles in the construction phase were found to be limited BIM skills of site personnel and hardware and technology limitations at construction sites. Limited skills and awareness of facility management personnel, limited awareness of lifecycle benefits and high initial investment were identified as major obstacles in operation and maintenance phase. The overall findings suggest BIM adoptionchallenges in Nepal are mainly related to the lack of capable human resource, lack of training, technological constraints and weak institutional support systems. The study shows BIM can enhance project planning, design visualization, costmanagementand early detection of design conflicts. BIM can eventually reduce mistakes and rework, improve efficiency and management of government assets 2 throughout their lifecycle.Developing national BIM standards, providing training, improving digital infrastructure and introducing BIM requirements in government policies, procurement and contract procedures can enhance adoption of BIM. Taking these measures can help Nepal move towards a more modern and digitally enabled construction sector.
