    Ability of bim to satisfy cafm information requirements
    (Ceylon Institute of Builders - Sri Lanka, 2013-06) Gnanarednam, M; Jayasena, HS; Sandayake, YG; Fernando, NG
    Facilities Management (FM) and Building Information Modelling (BIM) are contemporary day concepts that have modernised the way built environment behave. In modern day, FM concepts are moving towards to sustainable FM (SFM). Incidentally, Facilities Managers (FMs) become responsible for assuring the sustainability of facilities of the business. Modern day buildings are increasingly sophisticated and the need for information to operate and maintain them in sustainable manner is vital. Currently FMs rely on the information of the facility retrieved from conventional Computer Aided FM (CAFM). However, FM professionals face challenges from existing information inefficiencies resulting in unnecessary costs, productivity, efficiency and effectiveness losses where these leads to failure of SFM. Considering its favourable features, BIM had been identified as promising solution to effectively reach SFM goals. BIM conceptually has been developed to overcome the inefficiencies in conventional building information systems and recording methods. Combined data would enable the art of making any building more intelligent and sustainable. Significant efforts were found which had focused on getting the benefit of BIM for FM. However, there was no certain answer to “how far could BIM satisfy the information needs of CAFM?'' This paper proposes a methodology to theoretically answer this question, which had been proposed for the next step of the study being conducted in Sri Lanka

    Approach to sustainable development through architectural education: insight to the perceptions of sri lankan students
    (Ceylon Institute of Builders - Sri Lanka, 2013-06) Samaratunga, M; Sandayake, YG; Fernando, NG
    Sustainable development is considered as a multi-dimensional problem for integration of economic, environmental, institutional, political, social and personal human problems. Therefore, interdisciplinary interaction will be essential to reach the ultimate goals of sustainability. Architecture, as a key profession in the construction sector, plays a significant role in promoting the interdisciplinary interaction and a holistic approach to sustainable development. This approach requires a high amount of knowledge, skills and attitude which could be obtained through architectural education. The need of approaching sustainable development through education was accepted by the United Nations and has declared 2005 to 2014 as the decade of Education for Sustainable Development (ESD). Therefore, this paper intends to explore the relationship between the architectural education and sustainable design practice in the Sri Lankan context. Architectural educational content on sustainable development has two folds, such as, the technical component and non-technical component. The technical components mainly focus on providing knowledge and skills, which are more applicable towards the latter parts of the design process (design detailing). Non-technical components not only provide knowledge and skills but also attitude and could be applied from the early stages of the design process (Concept development, brief interpretation, etc). The methodology adopted is a survey (structured) research approach where data generated through a social survey and a literature survey would be analysed to reflect some thoughts. Social survey would be conducted through a structured questionnaire given to undergraduates and young practitioners of architecture from the two main schools of Architecture in Sri Lanka (City School of Architecture, Colombo and Department of Architecture, University of Moratuwa). Student perception on Sustainability would be explored through the parameters of personal interpretations, application frequency and satisfaction to non-satisfaction ratio. Reflections would include that the technical knowledge and skills need to be in equilibrium with the non-technical knowledge and attitudes given in architectural education to obtain a more holistic sustainable design approach.

    Assessing the bim maturity in a bim infant industry
    (Ceylon Institute of Builders - Sri Lanka, 2013-06) Jayasena, HS; Weddikkara, C; Sandayake, YG; Fernando, NG
    Building Information Modelling (BIM) is rapidly gaining acceptance of building industries internationally, and is likely to become the primary industry standard for AEC information exchange in near future. The built-in intelligence of BIM offers the highest potentials for adopting lean approaches for project delivery, and minimizing of risks and uncertainties; enabling highly sustainable procurement systems for the building industry. While it is accepted that BIM is in its infant stage in Sri Lanka and BIM technologies are rarely present, adoption of BIM has been identified to be timely. Use of inappropriate BIM adoption strategies would waste valuable resources and time. This will also hinder the industry acceptance of BIM. Development of reliable strategies requires information on current BIM maturity in order to identify the gaps. Wider gaps in a BIM infant industry give rise to the number of potential alternative BIM adoption strategies. Thus, a coherent assessment of current context is crucial to chose most suitable strategies. Bew- Richards BIM Maturity Model and Succar's BIM Maturity Stages were the widely referred models used to ascertain the BIM maturity of an industry or an organization. However, these were found to be less useful to assess a BIM infant industry. The study proposes framework comprising four components, viz. collaborative processes, enhanced skill, integrated information and automated systems, and knowledge management.

    A framework for environmental rating schemes for infrastructure projects
    (Ceylon Institute of Builders - Sri Lanka, 2013-06) Jayawickrama, TS; Ofori, G; Pheng, LS; Sandayake, YG; Fernando, NG
    Infrastructure plays a vital role in a country's socioeconomic development and there is a growing demand for infrastructure in developing countries. However, infrastructure development impacts the natural environment significantly. Therefore, it is important to consider the environmental sustainability of infrastructure projects. In the built environment sector, Environmental Rating Schemes (ERS) play an important role in evaluating and encouraging the implementation of sustainability at the project level. While ERSs have gained widespread attention worldwide, less attention has been paid to infrastructure, and it has tended to focus on the building sector. Furthermore, no ERSs for infrastructure are found in developing countries so far. It is important for an ERS to be type-specific and many building rating schemes have considered this. However, no type-specific ERS for infrastructure has been published so far. Moreover, the existing ERSs have been criticized for the absence of any theoretical bases. To address these gaps, this study aims to propose a theoretical framework for infrastructure ERSs in developing countries. The literature on environmental sustainability was reviewed to identify the important aspects which should be applied at the project level to achieve environmental sustainability in those countries. The factors were analyzed using Analytic Hierarchy Process (AHP). Results show the highest importance for minimising impacts of waste disposal and non-renewable energy sources followed by avoiding corruption. The study provides a theoretical basis for developing ERSs for infrastructure projects and a path for developing sector-specific ERSs.
