Industrialisation has led to a massive increment in resource consumption and waste generation, which demands improved management strategies for Waste Management (WM), especially in Industrial Zones (IZ). Thus, Industrial Symbiosis (IS) concept was raised as a suggestion for WM in IZs through resource optimisation. IS concept being a sustainable solution focuses on waste elimination by creating a network of firms for the purpose of exchanging waste, by-products, utilities, infrastructure, and knowledge. Sri Lankan IZs still have not yet established a proper method to manage IW, which has led to heaps of waste. Since IS is an effective and timely solution for this issue, this paper was intended to analyse the enablers which will be vital in facilitating the application of the concept of IS for better WM of IZs in Sri Lanka. Despite the abundant research on IS concept, a gap in literature could be identified when it comes to exploring enablers to adapt IS for better WM of IZs in Sri Lanka. A qualitative research approach with two case studies were used in this study. A total of 12 interviews were conducted and collected data was analysed using code-based content analysis. The enablers were extracted through the analysis of case findings using an abductive analysis. The empirical findings revealed 34 enablers under environmental, economic, social, regulatory, organisational, technology, and market categories. Reduction of environmental deletion, reduction of WM cost, public pressure, environmental regulations, social relationships, availability of technology and recognition from buyers were some of the key enablers identified in this study. The knowledge generated through this research can be used by respective industry practitioners in Sri Lanka in adapting IS concept for better WM of IZs in Sri Lanka.

Living wall systems are the vegetated wall systems where growth layer is located behind the plant and integrated onto the wall. They started to be used widely due to their many benefits such as increasing the energy efficiency of the building. Living wall can contribute to wall’s thermal performance by its shading, insulation and wind protection effects. However, there are limited studies which is done by simulation to investigate its insulation effect. In the previous studies, its shading effect is usually simulated, and evaporation and transpiration were not taken into account which are the major effect of being a live mechanism. In this study, it is aimed to see the effect of living wall’s orientation and the plant types on interior thermal conditions, by using a microclimate simulation program ENVI-met. ENVI-met provides a vegetation model that simulates evapotranspiration and interaction between the outdoor microclimate with indoor climate. In this context, the temperature differences that occur between the wall layers and interior surface temperature of the living walls are compared with those of bare wall for two cities in Turkey which are representatives of hot and humid climate and temperate climate. Thus, it has been seen especially the west and south facades of the building and also the plant types according to their leaf area index (LAI) affect the efficiency of the building depending on the climate.

Green roof is a building envelop embedded concept to compensate the consequences of green losses due to building constructions with its numerous benefits in all environmental, economic and social aspects. But the application of green roofs in Sri Lankan buildings is seemed to be limited due to the deficiency in comprehensive awareness of the benefits of the green roof concept among construction stakeholders. Though the global studies on green roof application are widespread among different green roof types, their results do not indicate any consistency between green roof application and climate. This warrants the current study to investigate the benefits offered by green roofs in the local context. A thorough literature synthesis had initially conducted to review the green roof concept, types of green roofs, and benefits offered. Subsequently, a preliminary investigation was performed to identify the green roofs available in Sri Lanka. Thereafter, the case study strategy was adopted to evaluate the benefits of intensive and semi-intensive green roof types through interviews. The collected data were analysed using manual content analysis. Analysis revealed that both intensive and semi-intensive type offers key benefits such as energy conservation, and stormwater run-off reduction in the Sri Lankan context. In addition, the intensive type offers benefits such as carbon emission control, and absorption of urbanized noise which can be aligned with the main criteria of sustainable sites, energy & atmosphere, and indoor environment quality of green rating systems. Therefore, the study suggests that an adequate recognition to green roof implementation in the green rating systems would enhance the green roof application and thereby contribute to achieving sustainability of buildings in terms of these criteria.

Selecting the most appropriate construction industry consultant (CIC) is a crucial process if projects are going to be successful. However, poor performance of CICs and failure to meet a client's needs are common, and the CIC selection process has not been adequately analysed in previous research. A systematic literature review of the CIC selection process will help to clarify the different approaches and methods. The study concluded with three common approaches for selecting the appropriate CIC: pricebased selection, qualification-based selection, and qualification-price-based selection. The selection approach is conducted either by using a direct or a comparative method. The direct approach is based on reputation or past experience with the client, while the comparative selection method occurs through an evaluation process and a list of selection factors. There are two processes involved in the comparative selection method: interview-based selection process and Multi Criteria Decision-Making (MCDM)-based selection process. However, while there are different opinions about what is the best way to select a consultant, the authors assert that the ideal process depends mainly on client and project conditions. Future study is recommended on this topic. This study contributes to the literature on the CIC selection and open the door to further studies such as developing a new selection approach or method and studying factors and criteria of CIC selection.

A disaster is known as an unexpected hazardous event that impacts the communities through extensive damage, disruption and potential fatalities, which makes the affected communities seek external assistance to recover from the impact. Post-Disaster Resettlement (PDR) has been identified as a good option to convert the destructive zone into a sustainable society with long term developmental guidance. PDR projects can be defined as a complex process that deals with uncertainty and change the facility partially or entirely by replacement. The success of PDR programmes highly influences the mitigation and preparedness phases of the next disaster. Currently, PDR projects in Sri Lanka are not at the required success level due to different types of social and economic challenges. This study, therefore, aimed to identify and develop suitable post-disaster resettlement strategies for the successful development of PDR projects in Sri Lanka. A qualitative research stance was used for the proposed research as it requires in-depth inquiry into the PDR strategies. The research developed twelve strategies to succeed with PDR projects in Sri Lanka. The required knowledge sharing among parties of the PDR project, and using disaster-affected communities for managing and controlling of the PDR project are the main key strategies. The study highlighted the importance of PDR strategies to Sri Lanka, factors considered when developing PDR strategies, the shortcomings that have been witnessed in past PDR projects, and the possible ways of developing appropriate PDR strategies for Sri Lanka. Further, the study identified the levels that each strategy must implement in the resettlement process.

Green walls are becoming an interesting solution to address the potential issues due to loss of greenery in the urban built environment. Even though green walls offer numerous benefits, the application pace of this concept seems slow in many parts of the world including Sri Lanka, which could be primarily due to the perception that the construction of green walls may involve additional costs compared to conventional walls and due to lack of awareness of its performance. This has driven the recent researchers to investigate the economic performance of green walls. However, those studies are limited to given local contexts, thus, the knowledge is scattered. Therefore, this paper aims to explore the economic performance of green walls in the global context collectively using a systematic review towards understanding the differences. Filtering the search for the period of 2010 to 2022 offered 15 out of 103 research articles suitable for the analysis. The cost data extracted shows high variability related to different characteristics of green walls, building envelopes, and climatic conditions. According to the review, the maintenance stage accounts for the highest portion of the Life Cycle Cost (LCC) in any type of green wall. The direct green façade is the cheapest option with lowest LCC compared to the indirect and living wall types while the living wall is the expensive type due to presence of more components. The review further confirms that in most instances, the economic benefits of green walls; increase property value, façade longevity, tax incentives, and energy-saving tend to offset the cost of green walls. It is expected that this collective review outcome would better guide the decision-making process of green wall implementation in a given context.

Buildings require maintenance for their continuous operation at a higher level through their extended life. Early prediction of maintenance costs (MC) would enable efficient maintenance and smooth operations of the buildings and thereby ensure achieving value for the investment. The effects of factors on MC provide a chance to refine the design to ensure the optimisation of MC during early design development. Thus, this study aims to analyse the MC of high-rise residential apartments along with the effects of factors influencing MC in Sri Lanka. Initially, a questionnaire survey was conducted to assess the factors’ impact on the MC elements based on a 1-5 Likert scale. Then, a case study approach was employed using three high-rise residential apartments with above 30 floors located in Colombo to analyse the costs of MC elements. The data collected from semi-structured interviews and document review were analysed manually as a percentage of MC. The findings revealed that MC accounts for 30% of running costs (RC). According to Pareto analysis, 11 out of 29 sub-elements including lifts and escalators, maintenance management, repairs and replacement, and electric power and lighting contribute to 80% of MC. Further, most of the building design factors and technical factors highly affect the MC. The annual MC per GFA is about Rs. 350.00. It is expected that these findings would enable the designers to forecast the MC and focus on the relevant design and technical factors to optimise the maintenance costs of highrise residential buildings at the early design stages.

The phenomenon of COVID-19 has introduced critical challenges in the architecture, engineering, and the entire construction industry. A safe Working Cycle is a Japanese concept. It incorporates to enhances the effective implementation of safety management systems, thereby helping to prevent health and safety issues. This research mainly aims at identifying the strategies for overcoming barriers to implementing the Safe Working Cycle (SWC) concept during the COVID-19 pandemics in Sri Lanka. The research study focused more on reducing health-related illnesses caused by COVID-19 than on the other physical safety issues at the construction site. In such a critical health issue, the protection of human resources, an essential part of the construction industry, should be prioritized. The aim of the Study was reached through the sequential mixed method. The semi-structured expert interviews were initially conducted, and after that questionnaire survey was achieved among health and safety officers in construction projects in Sri Lanka. In the semi-structured interviews, data were analyzed using Nvivo thematic analysis software and questionnaire survey; M.S. Excel analyzed the collected data. Following the findings, several potential barriers were arisen to implementing the SWC concept in the Sri Lankan construction industry: including limited Budget allocation, poor safety attitude, limited land space, strict project schedules, and unawareness of workers. Further, this Study also indicated several potential practical strategies to overcome these barriers identified for SWC implementation. Such as; Implementing the COVID-19 bio bubble concept, Organizing regular toolbox meetings, demonstrating sign boards specific to this new concept, arranging separate systematic time slots, buildup a good communication network. The safe Working Cycle (SWC) is not currently practised in Sri Lankan construction culture. However, health and safety professionals are familiar with almost every aspect of the Safe Working Cycle (SWC); therefore, it is possible to put this into practice in the Sri Lankan construction industry.

Skilled staff turnover plays a wide role in continuous knowledge loss in manufacturing organizations. The result of staff turnover impacts organizational performance, productivity, effectiveness, employee performance and knowledge. The importance of managing an organization’s knowledge is a need in organizations. This research identified the importance of knowledge management in the trailer manufacturing sector with high staff turnover. This enables project managers to take project knowledge management into practice within the organization. This study uses a qualitative research approach. The aim of the study was achieved by a case study research strategy along with 16 semi-structured interviews, which were performed as a data collection technique. Data were collected from the case study organisation, focusing on knowledge management methodologies used during the project phases and identifying the impact of staff turnover on organizational knowledge. The knowledge management techniques vary from one project phase to another project phase. Based on the outcome of this research, project managers can identify the most effective knowledge management techniques to be used at each phase. According to the study, the most frequently used KM techniques in the planning stage were “Learning & Idea Capturing” and “Refer Knowledge Base”. The most prominently used KM techniques in the designing stage were “Brainstorming” and “Learning & Idea Capturing”. While the most frequently used KM technique in the building, testing, and launching stages was found to be “Refer Knowledge Base”. From this research study, project managers can identify the critical areas affected by skilled staff turnover, how to prepare in advance and minimize knowledge loss.

The most prominently used KM techniques in the designing stage were “Brainstorming” and “Learning & Idea Capturing”. While the most frequently used KM technique in the building, testing, and launching stages was found to be “Refer Knowledge Base”. From this research study, project managers can identify the critical areas affected by skilled staff turnover, how to prepare in advance and minimize knowledge loss.","PeriodicalId":356554,"journal":{"name":"Proceedings of 10th World Construction Symposium 2022","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121662046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Apartment market can be recognized as one of the marketplaces severely affected due to the unprecedented global pandemic of COVID-19, which is currently driving towards a disequilibrium state. Hence, this paper aimed to investigate the impact of COVID-19 pandemic on the demand and supply of apartment projects in Sri Lanka. The qualitative research approach was followed in order to accomplish the research aim. A comprehensive literature review followed by fifteen semi-structured interviews were conducted with apartment industry experts during the empirical investigation. Collected data was analyzed using manual content analysis. The findings revealed, how each market determinant affected the demand and supply of apartments respectively during the COVID-19 pandemic resulting numerous challenges on the market participants, directing the apartment market towards a disequilibrium state. Urban living fears, demographic shifts, unemployment shocks, consumers’ financial concerns, tourism crisis along with several other factors caused demand to be dropped while approval delays, lesser investments, lack of funding, developers’ failures, market imperfection and construction delays majorly affect the supply of apartments. Although demand for apartments in some market segments showed recovery with the new normal adaptation followed by several positive market aspects, demand dropped within the rental market and upper tier remains constantly. However, supply side is worsening overtime since financial losses are lessening developers’ supplying capabilities, while the crisis within the construction sector getting more affected due to the country’s economic downturn.
