- item: Conference-Full-textApplicability of green roofs in Sri Lankan high-rise buildings: drivers and barriers(Ceylon Institute of Builders, 2018-06) Subaskar, C; Vidyaratne, H; Melagoda, DG; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGASSri Lanka is experiencing a construction boom and there are many high-rise building constructions coming up. Thus, many adverse effects are associated with high rise buildings. Greenery provides several benefits to the environment and reduces these effects. However due to limited space in urban areas it is impossible to plant new plants, trees and vegetation around the buildings. As a solution green roofs can be adopted as they provide many environmental and sustainable benefits from rooftops. Though this concept is more popular across many countries over the past few decades, still implementation of this technology in Sri Lanka is new and scant. Due to the lack of past researches, awareness on green roofs is very low for professionals, developers, government authorities, building owners and general public. The aim of this research is to identify and analyse the potential of green roofs in high rise buildings in Sri Lanka. A comprehensive literature review was carried out on popularity of green roof in global context, types of green roofs, components of green roofs, barriers and drivers in implementing green roofs. The data collection was conducted through expert interviews and questionnaire survey. Expert interviews were carried out to validate the barriers and drivers identified through literature review in Sri Lankan context and questionnaire survey was used to identify the most significant barriers and drivers. Purposive sampling techniques was used for selection of the respondents. The data collected from expert interviews were analysed through manual content analysis and the data collected by questionnaire were analysed using RII method. The final outcome of this study finds that green roof is an applicable concept for Sri Lankan high rise buildings.
- item: Conference-Full-textModel for analysing the drivers and barriers of e-procurement adoption to enhance the performance of procurement system in Sri Lanka(Ceylon Institute of Builders, 2018-06) Fayasa, AF; De Silva, L; Dissanayake, DMPP; Gunatilake, S; Waidyasekara, KGASThe growing need and competitive nature of firms in the modern world have been directed the organisations in discovering new solution to improve their business value and performance. E-procurement (EP) system is realised as an innovative technique by most of the practitioners and rate of adaptation is intensely increasing around the world. However, key literature findings revealed that organisations are struggling with EP system due to the lack of knowledge on factors influencing the successful implementation. This situation is similar to the Sri Lankan context as well. In this context, it has become a timely requirement to develop a mechanism for analysing such factors to facilitate a successful implementation. Therefore, this study attempts to develop a model for analysing the drivers and barriers of EP adoption to enhance the performance of procurement system in Sri Lanka. A qualitative approach was followed in which multiple case study was selected as an appropriate method for the research which allows to analyse within each setting and the evidence created from this type of study is considered robust and reliable. Accordingly, semi-structured interviews were conducted among the selected three respondents from each case to collect the data. Captured data was structured and analysed by using manual content analysis method with the support of NVivo software. Empirical investigation validated twenty-four drivers and seventeen barriers which are influencing the successful EP adoption. The research findings further disclosed six strategies to strengthen the drivers and weaken the barriers of EP adoption. Finally, a model was developed based on the research findings in order to facilitate the adoption of EP system in Sri Lankan context.
- item: Conference-Full-textPotential of applying earned value management (evm) as a performance evaluation technique in building construction projects in Sri Lanka(Ceylon Institute of Builders, 2018-06) Ekanayake, MGC; Jayasena, HS; Kolugala, LMBN; Sandanayake, YG; Gunatilake, S; Waidyasekara, KGASConstruction industry has some unique characteristics that brings specific challenges in achieving required performance. Currently majority of construction companies evaluate the project performance by program review method, which can identify the performance after the activity accomplishment or action is accomplished. The project should have begun to use the existing performance technique. Earned Value Management (EVM) is a more robust, internationally recognized and adhering process to evaluate the project performance. EVM considers the performance in Time, Cost and Quality aspects. EVM compares the project Planned Value (PV), Earned Value (EV) and Actual Cost (AC). Current knowledge showed no evidence of EVM in Sri Lankan construction projects. This research was conducted to identify the potential of applying Earned Value Management (EVM) as a Performance Evaluation Technique in Building Construction Project in Sri Lanka. The research followed a qualitative approach. The researcher could be able to identify the facilitators, barriers and the challenges of applying EVM in current context. Semistructured interviews were conducted to investigate status and key challenges for the implementation. After analysing the data, the researcher could conclude major barriers and challenges on implementing EVM as a performance evaluation technique for Sri Lanka construction industry. Its consumption of considerable extra cost, need to train staff, reluctance of some qualified employees to adhere to the technique due to various constraints could be identify as common bottlenecks.
