Applicability of bim technology for enhancing the lean construction process in Sri Lanka
(2023-07-21) Madusha, MDY; Francis, M; Liyanawatta, TN
Building Information Modelling (BIM) is widely implemented in construction industries around the world, providing many benefits. BIM has brought significant improvements in productivity, accuracy, and efficiency. Lean is an innovative construction management method that is closely linked to the overall lifecycle of a project to ensure its success. Lean and BIM are two different concepts used to enhance the value and quality of overall construction projects. The combination of these two concepts has been used to eliminate waste and encourage a streamlined workflow ensuring the delivery of value to the customers. But still, there is a lagging that can be identified in the applicability of BIM for enhancing the lean construction process in local scenarios. Therefore, the study explored the applicability of BIM technology for the lean construction process in Sri Lanka. Accordingly, a comprehensive literature survey and three case studies were conducted to collect data. Subsequently, the collected data were analysed using content analysis with the use of NVivo software. The study indicates that 12 lean techniques which have been implemented in local construction projects and 9 BIM-related software encourage the establishment of lean principles. The study further revealed, 7 common challenges while integrating of Lean-BIM and 9 solutions to overcome the challenges identified. Finally, a framework was developed based on the research findings to identify the current situation of the applicability of BIM technology for enhancing the lean construction process in Sri Lanka.

Barriers for implementing dispute review board (DRB) method to Sri Lankan construction industry
(Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Liyanawatta, TN; Abeynayake, MDTE; Sumanarathna, PMSU
In Sri Lanka, dispute resolution methods in construction contracts are Negotiation, Mediation, Adjudication, and Arbitration. Although the Dispute Review Board (DRB) method has been successfully used internationally for more than 30 years, it has rarely been applied in domestic contractual disputes. Thus, this research was conducted to identify the barriers hindering the implementation of the Dispute Resolution Board (DRB) mechanism in the Sri Lankan construction industry and to provide recommendations to overcome these barriers. This research was deemed necessary because the current dispute resolution methods could not effectively resolve contractual conflicts. Despite introducing DRB through Dispute Adjudication Boards (DAB), its potential benefits have not been fully realised in Sri Lanka. To achieve the purpose of the study, a comprehensive literature review was conducted first, and then a preliminary survey to identify the barriers to the implementation of DRB in the Sri Lankan construction industry. Subsequently, a questionnaire was administered to 44 professionals engaged in client and contracting organisations. The research findings revealed that the main barriers to the implementation of the DRB mechanism are unawareness of the concept of DRB, clients considering DRB as a burden and hassle for them, additional costs to be incurred, and lack of experience. Accordingly, the study recommends increasing the awareness of the DRB at the national level with the support of authorities to utilise it as a valuable alternative for resolving disputes in the Sri Lankan construction industry.

Building information modelling as a dispute avoidance mechanism in Sri Lankan construction projects
(Faculty of Architecture Research Unit, 2023-12) Jayarathna, HMMU; Francis, M; Liyanawatta, TN
Due to the complicated nature of building projects and the participation of several participants, disputes are inescapable in the building projects. The disadvantages of the Dispute Resolution Mechanisms (DRM) utilized in the projects have shifted the focus to conflict avoidance according to the premise that prevention is more effective than cure. On the other side, the chance of disagreements appears to be lower in projects procured by utilizing Building Information Modelling (BIM). However, there is a growing need to explore conflict avoidance from the standpoint of integrating Building Information Modelling in the Sri Lankan context. Therefore, this study seeks to investigate the applicability of integrating BIM as a dispute avoidance mechanism in Sri Lankan construction projects. A qualitative research approach was adopted to fulfil the study's goal. Specifically, the case study method was utilized, selecting suitable cases from the Colombo area that incorporate BIM in their respective building projects. Semistructured interviews were used to acquire research data from nine experienced individuals with BIM experience who were engaged in the selected cases. A strategic framework was developed based on the analysed causes of disputes in the selected cases, dispute avoidance tactics adopted in the cases, and BIM features that affect dispute avoidance strategies. The study concluded that BIM can be used as a potential dispute avoidance mechanism in Sri Lankan construction projects.
