Industry 4.0 driven technological advancements have accelerated the uptake of Offsite Construction (OSC), causing the need for re-skilling, up-skilling, and multi-skilling traditional onsite construction skills and competencies. The purpose of this paper is to develop a conceptual model that predicts OSC skills as a response to the OSC demand. The paper is a theoretical presentation of a skill profile prediction model which introduces the key concepts, OSC typology, OSC skill classification and their relationships. Components, panels, pods, modules, and complete buildings represent the OSC typology. Managers, professionals, technicians, and trade workers, clerical and administration workers, machine operators and drivers, and labourers constitute the OSC skill classification. The conceptual model takes the OSC project parameters: gross floor area, OSC value percentage and skill quantities as input and provides predicted skill variations as the output. The skills are quantified in “manhours/m2” under six skill categories, for five distinct OSC types. As such, the research presents a comprehensive conceptual model for the development of an OSC skills predictor to capture the skill variations and demand in a construction market moving towards rapid industrialisation. The research contributes to the existing body of knowledge by identifying the key concepts, parameters, and mutual relationships of those parameters that are needed to develop a realistic prediction of future trends of OSC skills.

The construction sector can be identified as one of the highest energy-consuming industries in the world. The energy usage of the construction, operation, and maintenance stages is significant due to the complex nature of the industry. However, energy is one of the most undervalued resources in terms of efficiency and conservation in the construction stage. Higher energy usage and energy wastage in construction sites can be identified as significant matters, and various energy efficiency measures have massive potential for saving energy during the construction stage. Accordingly, this paper aims to investigate the sustainable use of energy practices on construction sites in Sri Lanka. A comprehensive literature review was conducted to identify principles and practices of sustainable use of energy, energy-using activities, processes, and the most applicable energy efficiency measures. The research aim was achieved through a qualitative research approach, and four case studies on building construction projects were conducted within the Colombo district. The case boundary of the study is defined as high-rise building sites. Semi-structured interviews, site observation, and document reviews were carried out as data collection techniques within each case. The collected data were analysed using manual content analysis. Key findings revealed how to use energy sustainably, what are the current energy sources and alternative sources available, construction activities and equipment used in the construction process, and reduce energy wastage by using energy efficiency measures. Rework, and workers’ behaviour highly affects the energy wastage on the site. Lack of planning, lack of information, limited space, and poor responses from the construction organisation were identified as the most relevant barriers that influence sustainable energy use on construction sites. The proposed recommendations for improving the sustainable use of energy should be adopted at the project level. Measures exceeding the scope of site management, industry-level support, and policy intervention are required.

To gain economic advantages in the competitive world, governments tend to adopt new financing methods in construction projects. Accordingly, Public-Private Partnership (PPP) projects are a popular choice mainly due to the reduction in transaction cost and innovation. PPP projects have spread from the typical use on infrastructure projects such as airports, roads, railways, ports, and water sanitation to the more recent use for projects in the higher education sector such as universities and colleges. Thus, adopting PPP for the higher education sector related construction projects in Sri Lanka is vital to consider. Accordingly, this research aims to observe the Critical Success Factors (CSF) for the successful delivery of PPP projects in the construction projects of the higher education sector in Sri Lanka. A comprehensive literature review was first conducted to identify the CSFs of PPP in higher education construction projects and 22 CSFs were identified. The survey method was used under quantitative phenomenon since this research required evaluating the identified CSFs. The identified factors were evaluated through a questionnaire survey, which was conducted among the 30 selected professionals who are aware on PPPs, such as Quantity Surveyors, Project Managers, Government Professionals, and Academic Professionals. As the key findings derived through analysis, “communication between parties”, “transparency in the procurement process”, financial capability and support”, “project technical feasibility” and “appropriate risk allocation and risk-sharing” were determined as the top five CSFs for PPP projects in the higher education sector related construction projects in Sri Lanka. Furthermore, strategies were also proposed to ensure the successful implementation of CSFs in the higher education sector in Sri Lanka.

Megaprojects are an essential part in social, economic, and environmental developments and they attract a consortium of stakeholders ranging from governments, communities, international consumers, and suppliers. Hence, stakeholder management in these projects contributes significantly to projects’ success and sustainability. The research project, on which this paper is based on, aims to identify key challenges and propose suitable strategies to manage stakeholders in megaprojects for better sustainability outcomes. In achieving this aim, the research re-viewed key concepts related to project stakeholder management in megaprojects, explored sustainable challenges and analysed appropriate stakeholder management strategies through a secondary review of two major case studies of megaprojects in Sydney, Australia. The key findings discovered that the main factors influencing stakeholders were related to social, economic and environmental impacts of the project and, the need for managing them through proactive stakeholder management strategies. The implications of this research guide project managers on managing stakeholders on megaprojects and inform on possible challenges and solutions to achieve sustainable outcomes. Further research could extend and replicate on other case studies in different contexts and project types.

Whole life costing plays a major role in ensuring that value for money is attained from the inception of a building to its end of life. Availability of reliable cost data is essential ensuring that whole life costing is undertaken with utmost precision. This study explores the availability of reliable cost data for whole life costing in the Tanzania building construction industry. It aims at realising the key sources of cost data as well as analysing their reliability. It will also suggest ways to improve cost data availability in the industry. The research involved the use of questionnaire survey and structured interviews to collect data from quantity surveyors and other industry professionals respectively in Tanzania. The study revealed that in-house and market survey as the most familiar and most used sources of cost data in the Tanzania building construction industry. It also realised that running cost data, which are crucial for undertaking whole life costing, did not have a source in Tanzania which is contrary to other countries. The study also revealed that despite cost data sources being considered reliable, they still lacked credibility as most respondents still had doubts about them. To improve the availability of reliable cost data for whole life costing, the study suggests that the Tanzania building construction industry should adapt to the online information service which will ensure easy and fast access to reliable cost data. The industry should also engage in the collection and sharing of running cost data which is essential for whole life costing.

Infrastructure sector is a backbone of economic development for most of the countries worldwide. Indian AEC (Architecture, Engineering and Construction) industry is one of the leading sectors in terms of Gross Domestic Product (GDP) and employment. With the increasing demand for infrastructure and continuous development in field of technology, the speed of construction has been improved in various countries. But most of the projects still face the issues of cost and time overruns due to un-exploitation of digital tools and technology. Building Information Modeling (BIM) is one such promising technology that spans several levels of maturity (Level 0, 1, 2, and 3) and dimensions (3D, 4D, 5D, 6D and 7D). Many studies have shown that the construction industry is still lagging behind the rate with which technology should have been adapted, particularly in developing countries including India. This paper, therefore aims to answer systematically about various dimensions and level of maturity and its current status in Indian construction industry and the key factors responsible for un-exploitation of BIM’s features due to low maturity. Finally, the paper presented some future research agendas. The study’s findings may be of significant value to the practitioners and policymakers in incorporating mandatory BIM based framework for Indian construction industry and also in other developing nations.

Health Care (HC) is one of the most polluting industries and recognised as the second energy-intensive sector. Integrating sustainability into Facilities Management (FM) is imperative and could significantly contribute to reduce energy consumption, waste and day-to-day operational costs. However, operations of FM vary upon facility types, business sector, organisation characteristics, cultural context and organisational scale. Thus, this study examines the current practice of sustainable FM and its perceptions in HC organisations in Sri Lanka. A Delphi survey was administered to 10 experts in two rounds, who are specialised in FM practices in the HC organisations. A semi structured questionnaire was deployed and collected qualitative data were analysed using content analysis whilst quantitative data were analysed through mode, mean and quartile ranges to reach consensus. With respective to FM practice in HC it was found that 8 out of 10 organisations had no separate departments for FM to conduct FM practices. The functions were collectively carried out among departments namely; engineering, quality assurance and housekeeping. Operations delays incur additional costs and disputes were reported constantly. Also, building services was found to be the topmost FM service practiced. Integration of sustainability is at a moderate level and FM practitioners face higher level of constraints of which “high costs” obtained the highest rank. The study is novel in offering the state of the art of FM practice in HC organisations and adds values and provides recommendations for further research to maximise the contribution of FM towards sustainable practice. It thus directs FM practitioners to support the future enhancement of HCFM.

An increase in demolition activities has led to the generation of large amounts of glass waste. Due to its non-biodegradable nature, glass can stay in landfills for longer periods without decomposition; thus, it occupies a large volume of landfills. This study aimed to analyze the potential reuses and repurposing of glass waste in the construction industry. A systematic review of the literature was conducted, and secondary data were extracted. The data were analyzed qualitatively to achieve the objective of the study. The generation of glass waste in four different parts of the world, namely: Hong Kong, Australia, Europe and the USA has been studied to get an estimate for the increase in glass waste trends. The generation of glass waste saw a downfall from 2006 to 2010, was then steady from 2011 to 2016 and then slightly rose. A high volume of glass waste in landfills and its non-biodegradable nature has made it essential for the discovery of new methods of reuse and recycling of glass waste. Some of the potential reuse and repurposing options include Aggregate for Concrete, Filtration Media, Glass Fibres, Blast Abrasive, Roof Coating, Ceramic Based Products, Burnt Bricks, Low-Temperature Stoneware Tiles, Insulation, and Decorative Materials. The paper provides useful information to various stakeholders in the construction industry to understand how and where glass waste can be reused.

Effective and efficient waste management plans/systems are vital in reducing and maintaining the generation of construction and demolition waste. It was proved in previous research, proper rules and regulations affect the effectiveness of the waste management strategies used in disposing of construction and demolition waste. Therefore, this research aim is to identify the regulations applicable for the disposal of construction and demolition waste in Sri Lanka to propose improvements in the available rules and regulations. Comprehensive literature and document review were conducted to approach the aim of this research. Questionnaire surveys and expert interviews were carried out to validate the findings of the literature survey and to gather required data in identifying the issues related to current rules and regulations and proposing improvements. The findings revealed that many gaps can be identified with the current regulations used in the disposal of construction and demolition waste. The results of the research identified a lack of intention in government regarding recycling, avoiding improper landfilling, and avoiding illegal dumping of construction and demolition waste as major issues. The study finally concluded the necessity of modified rules and regulations regarding the disposal of construction and demolition waste.

The Covid-19 pandemic has created a new norm in which technology is at the forefront of keeping the globe running and rebuilding better after the crisis. Several countries practiced virtual ADR during the pandemic than in the pre-pandemic situation, and the virtual shift has gained traction. The research aims to explore the potentiality of the ADR methods in the virtual platform for the settlement of the dispute and make recommendations for effective legal implementation of those methods in the Construction Industry in Sri Lanka. The research aim was achieved through a qualitative approach; collected data through two stages: a preliminary interview and a semistructured interview with experts and finally analysed with manual content analysis. Key research findings are the opportunities and challenges to implement and conduct ADR in the virtual platform in the Sri Lankan construction industry. In addition, the strategies were collected to identify the potentiality of virtual ADR. The research concludes that the blended approach is suitable for Sri Lanka and the entire virtual ADR is not suitable. The entire virtual ADR shall be potential for Sri Lanka if all the opportunities are utilized and all the strategies are followed.

Several countries practiced virtual ADR during the pandemic than in the pre-pandemic situation, and the virtual shift has gained traction. The research aims to explore the potentiality of the ADR methods in the virtual platform for the settlement of the dispute and make recommendations for effective legal implementation of those methods in the Construction Industry in Sri Lanka. The research aim was achieved through a qualitative approach; collected data through two stages: a preliminary interview and a semistructured interview with experts and finally analysed with manual content analysis. Key research findings are the opportunities and challenges to implement and conduct ADR in the virtual platform in the Sri Lankan construction industry. In addition, the strategies were collected to identify the potentiality of virtual ADR. The research concludes that the blended approach is suitable for Sri Lanka and the entire virtual ADR is not suitable. The entire virtual ADR shall be potential for Sri Lanka if all the opportunities are utilized and all the strategies are followed. As the virtual ADR is a game-changer for the SL construction industry, regulatory bodies and arbitration institutions must take initiatives to implement and conduct virtual ADR successfully in the future.","PeriodicalId":356554,"journal":{"name":"Proceedings of 10th World Construction Symposium 2022","volume":"19 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":"134081126","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}
