Bridging the theory-practice gap in value management in Sri Lankan construction industry
Mahinkanda, MMMP; Sandanayake, YG; Ekanayake, BJ
Construction process is one of the most complex and dynamic procedures. Therefore, it is vital to use resources efficiently and effectively. Considering this requirement of any construction project, creating value for money is becoming important. It contributes to the economic, social and environmental aspects of a country. The concept of value is based on the relationship between satisfying needs, expectations and the resources required to achieve them. Value Management (VM) is recognised as a suitable approach to ensure value for money in construction projects. Although, VM concept is significantly used in developed countries, its applications do not seem to be well established in the construction industry in most of the developing countries including Sri Lanka. This is mainly due to lack of understanding of VM concept. Hence, this study aims to investigate how to bridge the theory-practice gap in VM in Sri Lankan construction industry, through seven case studies. Case study data collection was based on interviews, document review and observations and analysed using content analysis. The research findings revealed that these projects employed different kinds of VM methodologies derived from standard VM methodologies with the focus of various VM objectives. The study further identified number of reasons for theory-practice gap in VM such as lack of a formal guideline and less knowledge on VM, which dilute successful VM implementation. The experts further proposed train in-house VM facilitators, proper project planning, motivate investors, train Sri Lankan professionals by foreign experts and govern VM knowledge sharing as strategies to bridge the gap in order to deliver best value for client’s money.

Significance of construction technology knowledge for quantity surveyors in expressway construction projects
Jayawardhana, SKGUK; Hadiwattage, C; Mahinkanda, MMMP
The degree of social responsibility of professionals towards public projects are naturally high. Recently, in Sri Lankan context, expressway construction is becoming one of the major public project types. Due to that, the responsibility of professionals towards a successful expressway construction seems very high. Among professionals, Quantity Surveyor (QS) is a significant team member in any kind of construction project in terms of managing cost and time aspects. Being highly technical and complex, expressway QSs essentially need a significant level of construction technology knowledge to perform the duties and responsibilities. Therefore, the research was focused on investigating the significance of expressway construction technology knowledge for QS practitioners. The scope of the research was narrowed down to Sri Lankan expressway projects. A comprehensive literature review was carried out to identify the duties and responsibilities of QSs in expressway project stages. The research methodology was mixed approached comprising a questionnaire survey and s expert interviews round. Quantitative data analysis was carried out using RII method and qualitative data subjected to content analysis. The research concludes feasibility stage as the most technical knowledge sensitive stage of an expressway construction project with respect to the QS’s role. Further, QSs with less experience make projects vulnerable for more cost and time issues due to lack of technical knowledge and such scenarios may add black marks to the role of the QS in big picture, therefore it is essential for the QSs to keep updated with the changing construction technologies.

Suitability of traditional procurement system for green buildings in Sri Lanka
Rubasinghe, K; Disaratne, V; Mahinkanda, MMMP
Green building construction is a momentous process of sustainability. It signifies the environmental credibility of sustainable. Further, it addresses the energy performance, overall cost of the construction product and conservation of natural resources. Therefore, green building concept has foremost influence on construction industry. Yet, it has core barriers in cost, knowledge, risk and government factors when involve the green construction to construction industry. Hence, procurement system can involve in reducing those barriers. Green procurement signifies both product and process of the construction. Concerning the process base, there are different procurement systems involved in different countries which depend on internal and external factors. There is high involvement in design and build procurement system worldwide which include Sri Lankan context as well. The status of applying traditional procurement system in green construction is significantly high even though it is not considered as highest. Therefore, it has high involvement on addressing the barriers through critical factors of traditional procurement system. It was carried out nine expert survey with qualitative analysis in order to identify involvement of traditional procurement system to green building construction. Accordingly, it focused on the critical factors of traditional procurement system specifically cost, time, complexity, client’s involvement, project characteristics and technology. These success factors addressed the barriers which raised through high cost, lack of knowledge, risk and other influences of green building construction. Finally, this research subsidizes to knowledge, green procurement system provides the benefits to increment of green building construction in Sri Lanka.
