Business model concept for construction businesses: a literature synthesis
(Ceylon Institute of Builders, 2018-06) Abeynayake, DN; Perera, BAKS; Hadiwattege, C; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGAS
Despite the importance of a business model (BM) to an organisation’s success, clearing up the fuzziness of the concept of BM before applying it to any business or sector is worthwhile. Since definitions are expected to bring clarity, this paper attempts to analyse various definitions given to BM by different authors. Accordingly, eight notions around which 31 definitions of BM have been centred were identified. These notions are based on stakeholders, value, revenue, strategies, process, causality, elements and dynamicity of the business with which all the BM definitional views are associated. In addition to its two key roles, value creation and value capture, BM plays several other roles as well. Some of these roles relate to being an opportunity facilitator; a common language; a source of industry change; a source of competitive advantage and an exemplar. The paper also distinguishes the term BM from the other commonly used term in the business language, ‘strategy’. Once the basis on which the preliminary views expressed by past researchers on the concept of BM is understood, it will be necessary to review the literature once again to get an understanding of the BM elements, BM design, BM changes and BM innovations, so that the concept of BM in the construction business environment and culture could be fully grasped.

Effects of premature termination: case studies of sri lankan construction projects
(Ceylon Institute of Builders, 2013-06) Abeynayake, DN; Kumara, RNMU; Sandanayake, YG; Fernando, NG
Construction projects are inevitable. But they should be in proper way. However some of projects/contracts come to end before their actual completion. This is an adverse effect to the construction industry and it can be identified as a barrier for sustainable construction. Therefore there is a requirement of avoiding occurrence of adverse premature contract/project termination and mitigating their effects while promoting sustainable construction practices. Hence, the aim of the research is to investigate effects of premature contract/project termination before minimizing adverse effects. In accordance with existing literature, mainly three types of Contract termination can be identified as, termination due to default of client, termination due to default of Contractor and termination for convenience of Employer. But, contract/project terminated prematurely due to whatever reasons, their issues affect on many ways to project stakeholders. Further, less attention is given to some issues relating to project/contract termination like impacts of termination, relationship among parties after termination and steps to prevent premature termination. This research is conducted through three case studies of terminated construction projects in Sri Lanka. To gather data, semi structured interviews were carried out with professionals and unstructured interviews were held with technical employees. Further, three experts were interviewed to clarify compatibility with termination concept. The findings were revealed that there are good impacts as well as bad impacts on stakeholders due to premature project/contract terminations. Most of the time, it results in breaking the relationship among parties, creating disputes, blacklisting the contractor…etc. Further, the research is explored good practices for prevent adverse termination effect which can be implemented in construction industry.

Potential impacts of blockchain technology implementation on construction contract management in Sri Lanka
(Ceylon Institute of Builders - Sri Lanka, 2023-07-21) Karunaratne, BCMT; Abeynayake, DN
The construction contract is the mainstay for the ascendancy of the construction project requiring proper contract management. The Sri Lankan construction industry has many complications associated with contract management. Blockchain, as a decentralised transaction and data management technology, can potentially address the issues related to contract management amidst the impediments to effective implementation. However, blockchain technology adaptation in the Sri Lankan construction industry lacks evidence, even though other sectors, for example, banking and agriculture, are with the initial implementation. Hence, this research aimed to identify the potential impacts of implementing blockchain technology in construction contract management in Sri Lanka. A literature review was conducted to identify the concept of blockchain technology, its applications and its benefits. A qualitative survey strategy was adopted, and data were collected via semi-structured interviews in two phases; Phase I with ICT and finance industry experts and Phase II with construction contract experts. Samples were selected purposively through snowball sampling. The data analysis revealed that the awareness and use of blockchain technology in Sri Lanka are relatively low. However, Sri Lanka has the potential to adopt Blockchain in different fields, depending on their capabilities. Furthermore, the study found associated positive impacts of Blockchain, e.g., avoiding complex procedures, providing transparency, no ambiguities, no human errors and reducing political influence to mitigate contract management issues. Besides, Blockchain may negatively impact due to, e.g., high initial and maintenance costs, lack of knowledge and expertise, unavailability of rules and regulations, and reluctance to change those need mitigations.
