(2021-07) Senarathna, DR; Perera, BLSH
Material waste is one of the main reasons for the client to suffer due to increments in unnecessary costs. Among all construction material wastes, concrete waste highly draws expenses to the project stakeholders. As a main component in construction, the volume of the concrete waste in Sri Lankan construction projects are considerably high, when comparing with the other material wastes. Currently, most of the countries are moving towards the sustainable developments while minimizing concrete waste. Therefore, applying traditional practices to minimize concrete waste have not been successful over the years. The aim of this research study is, to minimize concrete wastes by implementing contemporary practices that assists to reduce the project cost in Sri Lankan construction industry. In order to achieve the aim, comprehensive literature review, a questionnaire survey and semi-structured interviews were conducted to gather data in both qualitative and quantitative procedures. The empirical findings revealed that concrete waste has a positive relationship with the project cost. Same time, discovered the drivers and barriers that gains while implementing contemporary practices in Sri Lanka. Concrete recycling, precast elements, lean construction techniques, value engineering methods and few more other contemporary practices were identified that leads to minimize concrete waste. The results from the interviews found that many projects are willing to implement mentioned contemporary practices within their construction projects although there are few barriers. These findings deliver a valuable evidence to the practitioners with an in-depth understanding about the essential necessity of contemporary practices to construction projects.

(Ceylon Institute of Builders, 2018-06) Senarathna, DR; Abeynayake, M; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
The basic characteristics of built environment activities are complexity and disputability in its own nature. This complexity drives most of the construction projects and contracts towards disputes between parties. Construction contracts in the industry are more complex than all other type of business contracts by its nature. This complexity itself has paved the path for disagreements between parties of such contracts. Although disputes are common in Sri Lankan construction industry as elsewhere in the world, dispute resolution mechanisms are not admired in Sri Lanka. The litigation process is the traditional mode of dispute resolution, drawbacks of litigation process have opened up the ‘Alternative Dispute Resolution’ (ADR) methods. Literature based on the process of Arbitration in Sri Lanka and other countries reveal that using Arbitration as an alternative method to the court system will be more beneficial than court litigation. It is evident that there would be a high possibility to ensure the efficacy of the process of Arbitration by minimising the interference of the judiciary. At present Arbitration as an ADR method does not efficiently resolve the disputes. This research examines the usage of Arbitration as an ADR method to resolve the construction disputes instead of traditional litigation. However, the current arbitration method and its practice hinders the advantages by irregular judicial interferences which prolong its efficiency. The aim of this research is to recommend effective amendments for current Arbitration practice in Sri Lanka by reviewing the impact of judicial interference. This research proposes a well-planned Arbitration method which can avoid pitfalls in the current legal regime of the Arbitration practice in Sri Lanka. Further it seeks to suggest positive amendments for the Act to avoid loopholes and minimise the challenging grounds of arbitral awards.
