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.

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

Plan outcome evaluation (POE) is very significant rather than focusing on planning process, usefulness of plan, content and quality of plan. POE has been ignored in the field of planning due to lack of proper POE method.This study focuses on the ex post facto evaluation considering the outcomes of action projects of development plans and aim to develop a POE method to evaluate outcomes of development plan towards the achievement of its objectives quantitatively since no one has made such an attempt. Achieving outcomes of development plan directly affect for sustainable urbanisation. A comprehensive literature survey revealed that adaptation of the components of objective driven, theory-driven and theory-based, utilization-driven and theoretical data-driven evaluation methods will lead to overcome related issues on plan outcome evaluation and identified basic four steps suitable to incorporate in any POE method.This developed POE method comprises four steps including mathematical models. Field surveys and questionnaire surveys were carried out to identify public perception on achievement of outcomes of action projects. Developed POE method can be used as a progress monitoring tool and as an outcome evaluation tool. This POE method will be a useful tool for planners, project managers and policy makers to improve planning practices and provide necessary knowledge for revising plansin order to ensure the sustainable urbanisation. This study can be extended to evaluate the outcomes of development plan when objectives are clear and measurable further considering theory, process and objectives driven methods.

“Sustainability” has emerged as a vibrant field of research and innovation over last few decades. The concept is based on three basic factors; environment, social and economic, namely the Triple Bottom Line. Frequently, the environmental aspect, despite the social and economic aspects, is given a major emphasis in the global arena of sustainable construction. The World Green Building Council (WGBC), being the leading institute in sustainability, has initiated the first step towards assessing the socio economic factors in the field of sustainable construction, which are being neglected in rating green buildings due to its immeasurability as a tool, by developing a framework for assessing the concerns addressed in the Triple Bottom Line. The WGBC criteria presented in seven sections hold concepts developed by the expert panel representing 14 countries, for assessing the social and economic factors. Since the concepts are in contrast with Sri Lankan context, they seek readjustment in order to match Sri Lankan context. Research agenda hascommenced with a comprehensive literature survey, followed by expert interviews and a questionnaire survey. The process of developing the theoretical framework to determine the appropriate weightages between each rating has proceeded using the indicators and benchmarks of the available frameworks. Adjusted criteria of the social and economic factors would be able to improve the applicability of GreenSL to assess the green buildings in Sri Lanka. Developed framework through the evaluation process in the research would be capable of assessing the Sri Lankan sustainable constructions in a more appropriate manner, with proper compositional integration of socio-economic and environment factors. A comprehensive assessment of sustainable construction could be achieved through the developedtheoretical framework that is fitted in to the Sri Lankan context with due consideration on aspects addressed in Triple Bottom Line; economic, social and environment.
