Publication Open Access The Impact of Labour Motivation on Project Performance with an Insight into the Sri Lankan Construction Industry(Sri Lanka Institute of Information Technology, 2023-03-25) Lakshan, H.G.S; Wijesinghe, T; Perera, B.K.CConstruction labour is a vital resource in the construction industry as they mostly reshape the raw materials into skyscrapers and other living enclosures. In Sri Lanka, the construction industry has been constantly exposed to many uncertainties and challenges. Being a developing country that lead to many socio-economic issues and constant changes in the living standards caused demotivational impacts on the Sri Lankan labour force. Thus, optimizing labour productivity through labour motivation is a significant challenge due to the various category and type of labours. This study aims to identify and evaluate different labour motivational factors in improving the building construction project performances. In accomplishing the aim, the mixed method approach was used and 5 number of interviews, 39 questionnaire responses were taken into the analysis. After the analysis there were 14 most significant labour motivation factors which applicable for Sri Lankan building construction industry. Cost centers for those were collected from the expert interviews and their cost on motivation factors were analyzed the data collected from the questionnaire. After the analysis financial and time cost centers have been identifies as the major cost centers that have been incurred when implementing labour motivational factors. Moreover, checked the association between labour motivational factors and project performance in terms of time saving, cost saving and quality improvement. As a result, they were associated with them. A framework was developed to aid in the selection of best motivational factors in optimizing project performance. As the last part of this study, the motivational recommendations were made to increase the labour productivity. Furthermore, these findings will be useful in optimizing building project performance.Publication Open Access 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, MThe 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.Publication Open Access Critical Supply Chain Problems In Contractor - Subcontractor Interface Of Sri Lankan Building Construction Projects(SLIIT, 2022-02-11) De Silva, P; Panagodage, T. LAs a developing country, construction industry provides considerable contribution to the Socioeconomic growth of Sri Lanka. However, successful completion of a construction project is yet a challenging task. It requires coordination, collaboration and management of different stakeholders with different objectives. While achieving the objectives of a construction project, a proper management of supply chain is vital as improper management of the supply chain impacts negatively on the construction project delivery process. Prior studies have identified several interfaces which impact on the successful project delivery. The mechanism related to contractor-subcontractor interface highly impacts the ultimate project outcome as it is directly linked with the delivery of the project. This study set out to identify the critical supply chain problems in contractor-subcontractor interface in Sri Lankan building construction projects. The study was derived through a mix method approach. Semi structured interviews were carried out among the industry expertise to identify the supply chain related problems. Thereafter, to identify the critical problems of supply chain, a questionnaire survey was carried out among the industry practitioners in the building construction projects. The data was analyzed using Relative Important Index in order to rank and identify the severity of each identified problem in the contractor – subcontractor interface. The study indicates that, using verbal information, lack of reference to the main contract and nonresponsible responses as the critical problems in the Information flow. In terms of the Material flow: deliveries are not according to the plan, poor labour management and noncompliance with material and components are ranked as the critical problems. Delay in payments, back-to-back payments and payment interest charging as the critical problems under the Capital flow. These findings may assist the industry practitioners to identify the criticality and monitor supply chain problems in contractor- subcontractor interface and to minimize them in building construction projects.
