BIM for flood mitigation: A survey-based case study

The construction industry is increasingly adopting digital technologies, with Building Inform- ation Modelling (BIM) gaining attention for enhancing flood mitigation planning. However, in Johor Bahru, where flood risks rise due to rapid urbanisation, BIM adoption for flood mitigation remains limited by knowledge gaps, technical and policy barriers, and weak stake- holder collaboration. This study aims to determine current BIM adoption levels, investigate barriers, and propose strategies to improve implementation in flood mitigation projects. A quantitative approach was employed using a questionnaire survey within a case study con- tractor organisation. Findings show 66.7 % of respondents frequently use BIM, with 60 % applying it at Level 3 maturity (fully integrated collaboration). Key barriers include high investment costs, lack of expertise, and limited access to accurate data. Proposed strategies include leadership support, training, financial incentives, and regulatory alignment. While adoption shows positive trends, wider implementation requires coordinated efforts to enhance BIM’s role in flood-resilient urban infrastructure.
