Enhancing value engineering application in the Sri Lankan building construction industry : a framework
(2021-07) Sandupama, AVPU; Ramachandra, T; Madushika, UGD
The concept of value engineering (VE) is used to optimise the cost, time, quality, and functional performance toward achieving the best value for client money. However, the application of VE in construction industries is limited as there are differences in the use of the VE concept to developing economies, application of cost-oriented procurement systems, and lack of a practically applicable framework. In the local construction context, VE is practiced in an ad hoc manner. Therefore, the current study aimed to develop a framework including a tailored approach to enhance the VE application in the building construction industry. A qualitative approach was adapted to solicit views of twenty-two (22) construction professionals who involved in the six (6) high-rise building construction projects and practiced the VE concept. Views of professionals were synthesised using content analysis and finally developed a framework including a tailored VE approach. The findings conclude that cost and time as the main value criteria which motivate the VE application. Further, VE application in the construction industry is initiated mostly in the construction stages while professionals’ preference is laid on the initial project phases. Consequently, the contractor change proposal was identified as the sound approach to deliver VE since motivations emerge during physical construction. Finally, a tailored VE approach was developed considering concept design, developed design, and construction stages with related VE motivations to enhance the VE application in the Sri Lankan building construction context in a simplified manner.

A framework for regulatory bodies to control informal building construction in Sri Lanka
Atapattu, AHATL; Abenayake, M; Dilakshan, R; Sandupama, AVPU
Socio financial and environmental affectability due to the construction improvements and its relativity with comprehension of building property advancement leads construction to become trendy activity in the society. In order to obtain the major roles in the economy of country construction conducted in to two segments called formal and informal. When render wider perspective on construction activities, there are highly considerable rate of failing, short coming, quality deficiencies etc. Building regulations facilitates to overcome and guarantee socially adequate levels of well-being, security, welfare and convenience for building tenants. This research undertaken using mixed method approach including pilot survey, questionnaire survey and expert interviews. From fifty (50) respondents to questionnaire survey, thirty eight (38) were identified as informal building constructions. It was employed to investigate the extend of obtaining the permits in building construction projects and discrepancies, deformations, laid significances on professional selection and considerations laid on design and construction stage. From the statistical analysis of the survey conducted identified addressable key areas to minimise informal construction activities, which causes deterioration in building constructions. In order to overcome that, eight (8) expert interviews were conducted among the professionals in relevant subject area. Gathered qualitative data were analysed using content analysis techniques. Consequently, the requirement of regulatory bodies to minimise the informal construction were identified which directly or indirectly influence positively on quality of buildings and defect free environment. Finally, framework demarcates the building informality, causation to building performance due to informal construction and building defects along with the remedial actions.
