Implementing lean practices in the construction industry remains challenging, particularly due to the lack of effective mechanisms to assess lean construction maturity. Despite the presence of limited literature on lean maturity models, no model has been developed specifically for the Sri Lankan construction sector. Addressing this gap, the present study takes an initial step toward developing a Lean Construction Maturity Model tailored to the Sri Lankan context by identifying the essential components required for its assessment. Adopting a pragmatic stance, the research employed the qualitative Delphi technique, involving 73 expert interviews conducted over three iterative rounds, followed by five validation interviews. Directed Content analysis was used to extract key elements for the model. The study identified three core components necessary for assessing lean construction maturity: attributes, process areas, and indicators. Specifically, eight attributes were revealed including Production Efficiency, Waste Elimination, Quality Management, People, Customer Focus, Lean Leadership, Transparency, and Lean Philosophy. These attributes are supported by 28 process areas and 140 indicators. Together, these elements form a structured, layered framework for assessing lean maturity. The study contributes original insights by considering the cultural, economic, and institutional dynamics influencing lean implementation in Sri Lanka. While the findings establish foundational components, further research is needed to develop and validate a complete maturity model. Practically, the study enables a more systematic and locally relevant approach to lean adoption, supporting improved industry performance. Socially, it promotes resource efficiency and project success, contributing to more responsible and sustainable construction practices in the Sri Lankan context.

Negotiation as an ADR Technique in the Sri Lankan Construction Industry
(Sri Lanka Institute of Information Technology, 2023-03-25) Deshabhi, K.A.G; Edirisinghe, V; Dahanayaka, G; Siriwardana, M
The construction industry is complex, and disputes are common in this industry. One primary method used in dispute resolution in the Sri Lankan construction industry is negation. Negotiation is considered a cost and time-effective alternative dispute resolution method. However, the contracts formed based on Construction Industry Development Authority (CIDA) do not include negotiation as a dispute resolution (DR) method. Therefore, this study aims to find the reasons for the failures in dispute negotiation and develop a framework to improve dispute negotiation in the Sri Lankan construction industry. There were two methods applied in this research. Because to avoid being based on a limited set of construction industry-related disputes. Five interviews were conducted by construction industry professionals to organize the data collection through documentaries and selected construction industry professionals are one projects director, one Chartered quantity surveyor, one engineer, one project manager, and one quantity surveyor to cover management level, chief level, and senior level. Then 250 claims were collected relevant to design changes, payment-related issues, time-related issues, documentation, and work quality. Out of those five types of claims, the majority of payment and timerelated disputes were resolved unsuccessfully through negotiation. Reasons for those disputes to fail in resolving through negation are negotiation outcome do not have statutory powers, the attitude of disputing parties, lack of negotiation skills, lack of trust towards negotiation, and less documentary information. The study recommends CIDA improve negotiation practices in the Sri Lankan construction industry by providing proper training, including negotiation as a compulsory DR, provide awareness programs to the industry stakeholders on dispute negotiation and its benefits.
