Conceptual framework for effective implementation of ‘project management institute’s standard for earned value management’ in Sri Lanka
Deniyage, CJ; Palliyaguru, R
Successful accomplishment of a project requires effective management of its performance. The performance of the most construction projects is tracked utilizing planned cost vs. actual cost measures only. Earned Value Management (EVM) technique came into existence as an effective performance measurement and a feedback tool for managing projects by emphasizing more on the Earned Value (EV) of projects. Regardless of the immense benefits of EVM, there are significant deficiencies in the process of implementation of the EVM technique in Sri Lanka. Therefore, this study aims to develop a conceptual framework for effective implementation of EVM in the Sri Lankan construction industry with specific reference to the Project Management Institute’s (PMI’s) standard for EVM. A qualitative research approach was used to accomplish the aim of the study. The empirical findings were analyzed using the manual content analysis technique to determine the degree of implementation of the PMI’s standard for EVM in Sri Lanka. The deficiency of professionals and inadequate conceptual knowledge were identified as the most critical barriers associated with the implementation process of the EVM technique. Allocating a separate team to execute the EVM technique, arranging short courses on EVM, developing a standard master format for project performance measurement are the measures that this study recommends promoting the adoption of the EVM technique in the Sri Lankan construction industry.

Workers’ behaviour towards noise pollution control on construction sites
Kaluarachchi, MS; Waidyasekara, KGAS; Rameezdeen, R
Noise pollution is a noticeable hazard in construction sites, which can cause severe damage to the health and safety of workers and the neighbouring community. Number of studies have investigated control measures for noise pollution, majority proposing regulatory and engineering control, which are expensive and mostly ineffective. While behavioural changes of workers could contribute to effective noise control, very few past studies have dealt with behaviour of construction workers. To fill this knowledge gap, this study used a questionnaire survey and analysed the responses using structural equation modelling by testing several hypotheses developed using the Norm Activation Model that investigates the relationship between attitudes and behaviour of construction workers. The sample belonged to a wide range of worker categories of major construction firms in Colombo, Sri Lanka. Results revealed that a positive relationship exists between personal norms and environmental behaviour. Furthermore, these personal norms are significantly informed by the awareness of consequences and a sense of responsibility to act to mitigate noise pollution in their sites. Thus, while workers are aware of the negative consequences of noise pollution and are responsible to act, an increase in environmental behaviour will occur via the activation of personal norms. Hence, workers tend to alter their behaviour when having altruistic moral norms. As a practical implication arising out of this research, these worker attributes could be strategically used by construction companies to create a conducive work environment where workers themselves take initiatives to deal with environmental destruction caused by construction activities.

What differentiates a smart city? a comparison with a basic city
Samarakkody, AL; Kulatunga, U; Bandara, HMND
Distinctive nature of the problems a city holds, baptise a “smart city”, which is a term, at the same time, is blamed for being befogged. Although defining the term “a smart city” is worth taking a risk, the maturity of the smart city definition in terms of practical use and research has not been reached. Even if it is defined, it would highly depend on the context and unique nature of cities. Yet there are city components that are only found in smart cities. A study of these components would be the most practical way of understanding “what make a smart city”. Therefore, this study aims to analyse literature, review definitional elements of smart cities, and derive a comprehensive list of smart city components. Not being a one size fits all, smart city definitions are often interchangeable with other well-defined city conceptions. Those conceptions are a source to outline what smart cities are. Therefore, the terms digital city, intelligent city, ubiquitous city, global city, and sustainable city are compared with smart city characteristics. In the same way, definitional elements from ten latest literature sources were identified. Smart city components identified in the literature were then reviewed and combined to form a list of components under the themes; smart economy, smart people, smart living, smart environment, smart mobility, and smart governance which were supposed to integrate with Information and Communication Technology (ICT) infrastructure. While these components are the frontline, smart cities also intent to ensure urban, public services, and citizen development. With this, the paper presents a holistic summary of the characteristics that define the smartness of a smart city.

Use of shipping container housing concept as a low cost housing solution for resettlement projects in urban areas
Ishan, JRP; De Silva, N; Withanage3, KT
Today, one-third of the world’s urban population live in slums and shanties., while prioritizing adequate housing as their basic need. They face a lack of basic needs such as clean air, water, sanitation and healthy foods. Rapid urbanization leads to increased demand for condominiums and focused on slum-free cities to get maximum utilization of high potential prime lands. As a solution, shipping container housing (SCH) concept has been successfully practiced in many countries in all over the world to promote low cost housing (LCH) for resettlement projects. Therefore, this research intends to explore the use of SCH concept as a LCH for permanent resettlement projects in urban areas of Sri Lanka. A comprehensive literature synthesis emphasizes the suitability of SCH concept as a LCH solution and it proved that approximately 60% of construction cost can be saved by using this SCH concept over the traditional construction methods. Selected case study for this research was “low income permanent resettlement programme in Colombo city”. Finally, the study revealed that use of SCH concept as a LCH solution for resettlement projects in Colombo will not be a feasible solution due to the specific retarding factors from the low income groups, specific characteristics of shipping container boxes and climatic conditions of Sri Lanka. Moreover, this study was very useful for the governing authorities to identify the leading alter factors between the theoretical concept and practical implementation of low income permanent resettlement projects in Sri Lanka.

Use of bim solutions to facilitate value management
Punnyasoma, JAG; Jayasena, HS; Tennakoon, TMMP
Value management is a practice of generating innovate alternative ideas to improve the value of a project where the goals are to achieve a more efficient design, identify alternative methods of constructions, identify and omit unnecessary cost components and managing the whole life cycle cost of the project. The aim of this research is to find the ability of BIM in incrementing efficiencies of value management process within Sri Lankan context. Case study method was used. The selected case is considered as a benchmark on sustainable buildings of the Sri Lankan construction sector. The sevenstep value management approach following the Client’s requirements identified for the project was first documented. BIM tools and features applicable for each step of value management process was then identified followed by clarification of the effect and the efficiency of each step of the process. A value management plan was built up with the use of BIM solutions for the studied case. BIM was identified as one of the most efficient and accurate media to extract the basic and detailed project information for value management process. Simulating, comparing and contrasting the information of rainfall, wind flow, daylight, cost, designs and resources for the implementation of passive cooling systems, lighting control systems, green roofing and alternatives to reduce grey energy was effectively analysed in this paper using BIM solutions.

Untapped potentials of built environment professionals in national disaster resilience action plans in Sri Lanka
Palliyaguru, R; Nawarathna, A; Jayalath, C
Even though many governments have ambitious plans for speedy and effective post disaster recovery a less success rate has been recorded in many parts of the World including Sri Lanka. In light of this situation, a growing call has been evident for greater engagement of the construction industry in the global effort of disaster resilience. This research is therefore aimed at recognizing the specific role(s) of built environment professionals previously unidentified in disaster resilience action plans in Sri Lanka. The research commenced with a literature review including the Sendai Framework which was the first major agreement of the post-2015 sustainable development agenda. A detailed desk review involved mapping the currently defined roles of the public sector in disaster resilience building in the National Disaster Management Plan (NDPM) in Sri Lanka with the open-source guideline called “The Built Environment Professions in Disaster Risk Reduction and Response” co-authored by Lloyd- Jones et al. (2009) that defines 29 distinct roles of built environment professionals. This research reveals that the built environment professionals in Sri Lanka have been heavily unrecognized and underutilized in the cause of disaster resilience where only 10 roles have been earmarked

Understanding liveability: related concepts and definitions
Tennakoon, TMMP; Kulatunga, U
The rapid unplanned urbanization of metropolitan areas has manifested number of challenges in terms of infrastructure, energy consumption, health care, waste management and resilience. Thus, forming “liveable” city for its citizens is an aspiration of the policy makers, designers and city planners. Yet, a detailed exploration of the concepts of liveability and liveability indicators has not been carried out. Thus, to this end, this paper advocates to define liveability and related concepts. For that an exhaustive literature synthesis has been conducted which simultaneously follows two different paths to define liveability. Firstly, it has reflected number of direct definitions from indexed literature related to liveability and contrasting the definitions of associate fragments of accustomed concepts such as sustainability and urbanization misapprehended as liveability. Secondly, a definition for liveability was derived through considering the liveability indicators of different liveability indexes According to the indicators, liveability represents social and economic approach. Yet, the concepts of sustainability was based on social, economic and environmental aspects when discussed along with liveability. Hence, Liveability is the balanced and favourable living conditions within a geographical area and liveable cities are such centralized communities with comparatively high population to the rest of the region. The policy making, planning, and political authorities need to ensure the balance of the habitats by defining liveability to reflect the social, economic aspects emerged through the existing indicators and the environmental focus of sustainability concepts.

Typologies of offsite construction
Ginigaddara, B; Perera, S; Feng, Y; Rahnamayiezekavat, Payam
In the 21st century, where smart and modern technologies are developed at an expeditious rate, construction industry has survived over centuries, despite its slow rate of technology adaptations, poor productivity, lower sustainability and vastly reported skill shortage. Technological advancement is the catalyst to solve these issues attaching extreme significance to transform the construction industry in line with industrialisation, digitalisation and globalisation. Sequential industrial revolutions have evolved to the present day’s Fourth Industrial Revolution which is also known as Industry 4.0, under which offsite construction leads to the reduction of onsite labour intensity and shift the tasks to factory based manufacturing paradigms. Study on offsite construction revealed different types of offsite construction available in literature; none of which specified a logical method of offsite construction types development to suit the current technology advancements in the global construction arena. Available literature rather mention types of offsite construction based on examples and not the construction technology or combination of onsite to offsite work component. Therefore, this research was carried out to develop typologies of offsite construction using 10 available types of offsite construction. Literature was analysed using content analysis method through the NVivo 2012 (QSR) computer software. Findings revealed six typologies of offsite construction with incrementing portions of offsite construction in the order of; Components, Panels, Pods, Modules, Complete buildings and Flat pack. Therefore, this research contributes to knowledge by the development of typologies of offsite construction through a scientific approach while addressing the 21st century technology advancements available in the construction industry worldwide.

The concept of value engineering and its assimilation in Sri Lankan construction industry: a literature review
Hyderaly, H; Thayaparan, M; Aarifkhan, F
Value is an ideational thought by which a worth of a good or service is expressed. Value Engineering is one of the tools used to evaluate such value and provide solutions for best fit value in real time. The core principle of practicing value engineering is to achieve value for money in construction projects, but it also bestows practitioners with added advantages such as innovative alternatives and enhanced quality. Even though value engineering is practiced globally, application of value engineering in Sri Lanka is highly limited due to lack of knowledge and awareness of the concept of value engineering, lack of realisation of the benefits it can bring to the construction projects and lack of government support. Hence, Sri Lankan construction industry lacks initiatives to pursue integration of value engineering in construction projects. The objective of this paper is to explore the idea behind the term “value” through value engineering and manifest previously identified causes and mitigation strategies to enhance value engineering practices within Sri Lanka. A comprehensive literature review has been carried out to disclose facts and cues of value engineering identified globally and to contextualise the concepts of value engineering within Sri Lankan construction industry. This paper emphasises that value engineering enhances the total value of the project while irradiating unnecessary costs associated with the projects. However, Sri Lankan construction industry is not practising value engineering in its full potential due to barriers identified above. Recommendations were, therefore, proposed to reveal the importance of standardising value engineering practice in Sri Lankan construction industry. .

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.

Stakeholders’ involvement in successful implementation of waste to energy projects: case studies in Sri Lanka
Kumarasiri, DMGBT; Dissanayake, MPP
Same as to many countries, Sri Lanka is also facing a waste crisis due to the issues in municipal solid waste management. As a solution, Waste to Energy (WtE) concept was aroused, which transforms waste to energy in the form of electricity. Although it was a successful strategy for many of the countries, in Sri Lanka, most of the instances, WtE projects were resulted in failures due to issues provoke in the implementation. Poor stakeholder management has been one of the key contributing issues behind these failures. Hence, there is a timely need of identifying key stakeholders and their role to pledge project success. Despite the abundance of research on WtE projects, a gap in literature could be identified, when it comes to exploring stakeholders’ involvement in successful implementation of WtE projects in Sri Lanka. Thus, this study is aimed at bridging this knowledge gap. A qualitative research approach with two case studies were used in this study. A total of 12 interviews were conducted and collected data were analysed using content analysis. The empirical findings revealed that government, community, central environmental authority, engineering procurement and construction contractors, municipal council and central electricity board are the most influential stakeholders involved in the implementation of WtE projects. Although their level of contribution is varied to each other, all stakeholders along with their interests and involvement collectively thrive to assure the successful implementation of WtE projects in Sri Lanka. The knowledge generated through this research can be used by respective industry practitioners in Sri Lanka in implementing future WtE projects successfully.

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.

Herath, AGTL; Mallawaarachchi, H; Rathnayake, RMDIM
Service consistency acts as a key media to achieve sameness and fairness in service delivery. Service consistency is vital to attraction of new customers, enhanced corporate image, reduced costs, and increased business performance. Nonetheless, struggle in developing and applying measurements for service quality can be commonly identified with service consistency failure situations. Hence, to better manage changes as well as to overcome such issues, organization should adopt a proper methodology to improve service consistency for Facilities Management (FM). Thus, this study aims to improve the service consistency of FM service proving organizations in Sri Lanka. Case study method was adopted in qualitative phenomenon. Under the case study method, three cases (FM service providing organisations) were studied. Twelve (12) semi-structured interviews were conducted among the FM related professionals in the selected cases to collect the data. Case study data were analysed by using the content analysis and crosscase analysis techniques. Direct interaction with customers, complain handling procedures, conduct skill development programmes, collect customers feedback and recruit experienced professionals were identified as some of the existing strategies used for service consistency. Different customer expectations, employee turnover, communication errors and lack of customer experience about FM services were revealed as major issues for service consistency. Accordingly, the suggestions, including sharing information with each employee, improving decision making skills, developing customer care strategies and implementing better recruitment system, were proposed to overcome the identified issues of service consistency in FM service providing organisations in Sri Lanka.

Real-virtual synchronisation: a review on the state-of-the-art geometric digital twinning of infrastructure
Ariyachandra, MRMF; Samarakkody, A; Perera, BAKS
In the United Kingdom (UK), recent developments in the construction industry have increased the demand for digitised infrastructure, which facilitates the investigation of the as-is performance of assets. This establishes the need to create and maintain up-todate digital copies of infrastructure assets, often labelled as Digital Twins. Digital twins are obtained by converting the unstructured data formats of the real-world assets, such as point clouds, into high-level digital representations. Yet, only few assets today have usable digital twins because of the high costs of the latter. This counteracts the benefits of the twins and reduces dramatically their true potential. Hence, there is a pressuring need to automate the process of creating digital twins. Geometric digital twin, the most basic form of the twin, contains only the geometry of the physical asset. This paper reviews the work done in computer vision, geometry processing, and civil engineering fields to determine the potential that exists for automatically producing geometric digital twins of infrastructure.

Potential of using big data for disaster resilience: the case of Sri Lanka
Rathnasinghe, AP; Kulatunga, U
The epoch of big data is evolving new possibilities for Disaster Management (DM). The concept of Big Data has been constantly scrutinised in terms of data creation, storage, retrieval, and analysis where professionals have identified its significance upon the volume, velocity and variety. Big Data provides the opportunity to gather more information in less time. Hence, analysis of Big Data can substantially enhance various disaster resilience activities such as issuing early warnings for evacuations; help emergency response personnel to identify areas that need urgent attention; coordination of disaster management activities; and to identify the most effective response methods for various situations. Therefore, Big Data is identified as a great catalyst for disaster response and, for better understanding of the damage situation and decision-making. Moreover, Big Data has the potential to improve disaster resilience by connecting people, processes, data and technology. However, it is essential to understand the type of Big Data that needs to be generated, to develop the data analysis as in necessary to help with real time responses, decision making and tracking of disaster victim. In order to accomplish the aim, a qualitative research approach was followed. This topical study marked the importance of big data in predicting human behavioral patterns during a disaster. Accordingly, the effective management of human and physical resources in habitual disaster territories was appraised through existing case studies in developed countries. Further, the research has successfully identified the challenges in employing Big Data upon its legal and technological barriers.

Policy gaps that deter fostering sustainable construction in Sri Lanka
Jayalath, C; Perera, BAKS
One of the guiding principles used for structuring the policy of construction in Sri Lanka is to ensure achieving sustainable development. Though the construction practitioners in Sri Lanka are aware of sustainable construction practices, there is lack of verification as to enthusiasm of the state policy that has been extended to this noble cause. A desk review was carried out to demystify the existing policy directions. A comprehensive literature survey was carried out to identify the drivers and barriers of its implementation. A structured questionnaire survey was conducted among 100 individual practitioners to gauge their perception and experience. 80 responses were received, 62 were considered valid for analysis. Data collected were then analyzed using the relative importance index. It was revealed that the key driver is end user requirements and the crucial barrier is lack of policies. Only 3 out of 17 dimensions have been at least superficially earmarked within the policy framework. The study suggests that the uptake of enhanced policies would indeed help in fostering sustainability. The outcome will be valuable for the government officials to formulate a policy that truly promotes strategic direction. This is the first local research on identifying policy gaps related to the subject arena.

Optimising the industrial symbiosis (is): the proposed redevelopment
Mallawaarachchi, H; Sandanayake, YG; Karunasena, G; Liu, C
Industrial symbiosis (IS) has been emerged aiming the integration of industrial complexes, in which by-products of materials and energy are using as feedstock instead of being wasted. Since organisations cooperatively increase their mutual sustainable benefits simultaneously through IS, a number of IS projects have been initiated across the whole world. However, most of the projects have been failed and discontinued in long term undermining the expected collaborative gains and efficiencies. Hence, recent studies articulate the necessity of having a standardised mechanism towards implementing the resource efficiency optimised IS designs. Thus, this paper aims to present the issues in the current process of IS development in order to propose a mechanism for redeveloping the process through resource flow efficiency optimisation. A systematic review of key literature was conducted in the areas of IS, its design and implementation procedures. The data collected through the secondary survey was then analysed manually to identify the different stages of the IS development process and related issues. As many scholars recognised, most of IS projects have been discontinued due to the shortcomings and the inefficiencies of the IS development process. Thus, the necessity of having a standardised and more robust model for optimising IS is recognised. Finally, the proposed redevelopment is conceptualised by introducing a new phase of re-evaluation and optimisation modelling to evaluate the symbiosis relationships prior implementation to consider them either for implementing or for replanning.

Mechanical and electrical (m&e) training for quantity surveyors to contribute to carbon reduction in buildings
Seidu, RD; Young, BE; Thayaparan, M; Rodmell, S; Robinson, H
Estimates on the level of carbon emission varies but it is generally accepted that buildings consume about half of energy and contribute to greenhouse gas emissions. Mechanical and electrical (M&E) services accounts for a significant proportion of building projects. Apart from the cost effect, a reduction in carbon footprint can be achieved through M&E services as the capital allowances system and tax relief provides the mechanism to promote sustainability through innovation in green technologies and energy efficiency. However, the training of quantity surveyors in M&E is often ad hoc making it difficult to realise the maximum potential in carbon reduction. The aim of the study is to enhance the M&E trainings to the Quantity Surveyors (QSs) in order to better contribute to carbon reduction and sustainability of buildings. The objectives were formulated as to examine the opportunities for carbon reduction through capital allowances and tax relief and the training implications for QSs. Using an explorative survey and semi-structured interviews, the study found significant gaps in knowledge of the quantity surveyors as limited attention is given to training in M&E services. There is need for a review of training programmes to ensure that the QS professionals can maximise the potential in reducing carbon emission through the provision of appropriate cost advice on M&E services that will benefit from capital allowances and tax relief. Other countries can learn from the experience of the UK Government policy, statutory and regulatory framework that underpins the development of capital allowances and tax relief to change behaviour by providing tax and fiscal incentives that will have a positive impact on carbon reduction to mitigate climate change.

Mapping and improving sustainable construction management through social network analysis: a review
Madhusanka, N; Pan, W; Kumaraswamy, M
Social Network Analysis (SNA) has been used in multidisciplinary research during the past two decades due to the unique nature of network visualisation and extensive analytical capabilities. This tool has also gained increasing attention among the researchers in the sustainable construction arena in recent years. Nevertheless, a thorough review has not yet been done to review the application of SNA in the sector of sustainable construction. This paper attempts to address this gap through a comprehensive review of previous journal publications. Accordingly, 73 journal papers were initially identified for review through the “Web of Science “publications database. Subsequently, a bibliometric analysis was done through “VOS viewer” software package to identify the research trends throughout the past years. The results show significant progress in relevant publications during 2014-2018 and a major contribution to research from China. After an extensive filtration process, 17 particularly relevant journal papers were identified which have applied both social network visualisation and analysis techniques for the sustainability aspects of construction. The contents of these papers were comprehensively analysed in terms of data collection methods, network analysis techniques, network structures and sustainability knowledge areas. Finally, this paper contributes to theoretical knowledge in this domain, by suggesting a future research direction through a SNA conceptual model to analyse stakeholder collaborations for project life cycle sustainability initiatives. The findings of this paper will serve as a good source for future researchers to comprehensively identify, compare and contrast the applications of SNA techniques for sustainability related studies in the construction sector.
