Cost overrun in the design and build (D&B) procurement method is a significant obstacle in achieving the project goals. Therefore, it has become critical consideration over its numerous benefits when selecting this procurement method. However, applying new technologies, such as Building Information Modelling (BIM), can significantly minimise this issue. Thus, this study aims to investigate the use of BIM to manage the cost overrun issues in D&B projects. A qualitative approach based on two rounds of interviews was conducted to collect the data. The study findings revealed ten highly important causes of cost overrun in D&B projects. Continuous design and drawings changes due to incomplete initial drawings prepared with insufficient design data at tendering stage, errors or omissions revealed during construction, and inefficient planning and scheduling by the contractor were the top three causes. Further, BIM functions such as interoperability and exchange of information, clash detection, digitalised quantity take off, and cloud computing were identified as they can be used to manage highly important causes of cost overrun in D&B projects. This research assists professionals in identifying the most appropriate BIM functions to reduce the fear of price uncertainty when implementing the D&B procurement method in their projects. Further research on identifying the barriers and suitable strategies for implementing BIM in D&B projects to reduce cost overrun can be based on the present study.

The construction contract is the mainstay for the ascendancy of the construction project requiring proper contract management. The Sri Lankan construction industry has many complications associated with contract management. Blockchain, as a decentralised transaction and data management technology, can potentially address the issues related to contract management amidst the impediments to effective implementation. However, blockchain technology adaptation in the Sri Lankan construction industry lacks evidence, even though other sectors, for example, banking and agriculture, are with the initial implementation. Hence, this research aimed to identify the potential impacts of implementing blockchain technology in construction contract management in Sri Lanka. A literature review was conducted to identify the concept of blockchain technology, its applications and its benefits. A qualitative survey strategy was adopted, and data were collected via semi-structured interviews in two phases; Phase I with ICT and finance industry experts and Phase II with construction contract experts. Samples were selected purposively through snowball sampling. The data analysis revealed that the awareness and use of blockchain technology in Sri Lanka are relatively low. However, Sri Lanka has the potential to adopt Blockchain in different fields, depending on their capabilities. Furthermore, the study found associated positive impacts of Blockchain, e.g., avoiding complex procedures, providing transparency, no ambiguities, no human errors and reducing political influence to mitigate contract management issues. Besides, Blockchain may negatively impact due to, e.g., high initial and maintenance costs, lack of knowledge and expertise, unavailability of rules and regulations, and reluctance to change those need mitigations.

The construction industry in New Zealand (NZ) plays a significant role in the country's economy. Similar to many other countries around the world, the construction industry in NZ is also prone to many disputes, which sometimes end up in courts. To investigate comprehensively about the disputes in the construction industry, several researchers have analysed court cases internationally. There is only a limited number of studies in NZ construction industry that followed court case analysis. This study has been carried out in search of quantitative aspects of 35 construction industry-related court cases in NZ. Based on the studied 35 court cases in NZ, majority of them has fallen into the area of payment issues, quality of works and variation entitlements. Poor contract understanding and administration, contractor's quality of work and poor contract arrangement have been identified as the most recurring primary causes of disputes. Further, the majority of cases that were heard before NZ courts had followed lumpsum contracts and traditional procurement route. The findings of this study is beneficial to the construction industry practitioners to avoid disputes by early identification of common issues in the industry.

Construction projects involve major resource consumption, particularly in materials which can account for up to 60% of the total construction cost. Construction logistics is the integration and collaboration of several activities to plan, execute, and control the flow of physical objects from their point of origin to their point of consumption. While logistics plays a significant role in minimising material costs, the construction industry tends to pay less attention to logistic cost minimisation. This paper aims to identify construction logistic cost components and propose strategies to minimise these components on construction material cost from a contractor's perspective. Accordingly, the literature review highlighted the significance of construction materials as a resource for construction projects and the importance of material costs in total construction costs. Moreover, semi-structured expert interviews were conducted with twelve (12) experts involved in construction logistics to gather data. Both on-site and off-site experts were included in the sample. Manual content analysis was used to analyse the collected data due to its flexibility and adaptability for small sample sizes. Thirteen (13) strategies were proposed to minimise construction logistic costs on material costs, including proper knowledge of the logistic process and its cost components and implementing proper logistic cost minimisation strategies through coordination and collaboration between the head office and the site. The findings of this study are expected to contribute to the construction industry's better understanding of the importance of logistic cost minimisation strategies and their potential benefits.

The construction industry is labour-intensive, and any conflict involving workers affects the project's overall performance. The present study identified potential conflicting factors and assessed the relative influence of those factors on the performance of workers. A total of nine conflicting factors were identified based on relevant literature. A questionnaire survey was prepared, and responses were collected from workers by visiting four construction sites in India. The data was then analysed using descriptive statistical methods. It was found that payment delay and overworking were the most influential conflicting factors on worker performance. Inadequate resources, lack of communication, lack of education/training, time pressure, and factors related to workplace environments such as noise and dust were also identified as contributing factors to worker conflicts. In contrast, lack of safety and low-risk perception were identified as the least impactful on performance. Addressing these conflicting factors can improve worker performance and job satisfaction, improving the project's overall performance. The study's findings can serve as a guide for employers and managers to create a positive work environment and address the difficulties faced by construction workers at job sites.

This research study aims to explore the necessity of implementing desalination plants as a solution to address water scarcity in the dry zones of Sri Lanka. Water sustainability is crucial for ensuring the availability and preservation of water resources to meet the needs of current and future generations. Various innovative methods, including rainwater harvesting, irrigation efficiency, sewage water treatment, and desalination, have been employed to minimise water scarcity. Desalination, in particular, plays a vital role in meeting the growing water demands by removing salt and harmful elements from drinking water, making it safe for consumption. The primary objective of this research is to identify the specific need for desalination plants in the dry zones of Sri Lanka, while also examining the underlying reasons for water scarcity in the region. The methodology employed in this study involves template analysis, utilising data collected through expert surveys. Six experts were selected for semi-structured interviews, ensuring saturation in information gathering. The findings of this research reveal nine crucial factors that necessitate the implementation of desalination plants in the dry zones of Sri Lanka. These factors include irrigation inefficiency, groundwater depletion, the prevalence of waterborne diseases, insufficient rainwater harvesting systems, limitations in current water distribution methods, the impact of climate change, population growth, and challenges faced by industries operating in the region. The findings underscore the importance of implementing appropriate strategies to mitigate water scarcity and ensure a reliable and secure water supply for the region's present and future needs.

Buildings have a significant impact on climate change. The building industry is the world’s biggest energy consumer and the building's operation accounts for 80–90% of its total energy consumption over its lifetime. Data-driven solutions for the management of carbon footprint in buildings have great potential due to the data science field's rapid growth and the expansion of operational building data availability. Therefore, this study's aim is set as to investigate the potential applications of data science for the management of carbon footprint in buildings. The study adopted a systematic literature review as a research methodology. Accordingly, 31 publications were reviewed using the content analysis technique. The study revealed that facilitating pre-process of the operational data of buildings, fault detection and diagnosis, implementing waste management in buildings, conducting the building energy performance modelling, conducting the parametric analysis at the design phase, evaluating the energy efficiency of building designs, benchmarking evaluation, control optimisation and retrofitting analysis are the major applications of data science to the management of carbon footprint in buildings. Moreover, the study suggested carrying more studies should be done on automating and building operational data pre-processing tasks, gathering sufficient labelled data for all possible faulty operations and applying modern big data management tools and advanced analytics techniques lead to improve the applications of data science in the built environment. The results from this study provide better guidance to building sector stakeholders, information technology sector stakeholders, academic persons, non-governmental organisations (NGOs) and other relevant authorities to address the carbon footprint in buildings using data science applications.

The waste generation due to the plumbing work substantially influences the total waste. Waste management is one of the most critical processes to achieve effective and productive construction projects successfully. Lean is a philosophy that is adopted in several sectors to mitigate waste. Thus, this paper intends to identify the adaptability of lean concepts to reduce plumbing waste in high-rise building construction in Sri Lanka. Data collection was done through two Delphi round interviews. The collected data were analysed using manual content analysis. As a result, comprising a total of twenty-seven barriers were identified under five sets of barrier groups for implementing lean concept to reduce plumbing waste in high-rise building construction in Sri Lanka. The strategies to successfully overcome each challenge and barrier were identified. Conducting CPD programmes, training programmes, showing the benefits of lean implementation and providing knowledge about lean through universities and other higher education institutes are the most common strategies to overcome the barriers to lean application. This study paves the path to lean professionals to align their strategy with lean practices by understanding and identifying the major obstacles.

The construction industry creates a considerable impact on the country’s economy. The current economic crisis has severely affected the Sri Lankan construction industry whereby also affecting the entire construction supply chain. Researchers have mentioned that a project abandonment has an overall negative impact on both economy of the country and the construction industry. Thus, this research paper aims to explore the reasons for the abandonment of construction projects during the current economic crisis in Sri Lanka and identify the remedies to avoid in the future. A comprehensive literature review, a questionnaire survey, and semi-structured interviews were conducted to gather data in both qualitative and quantitative procedures. Semi-structured preliminary interviews were conducted to gather preliminary data before developing the final questionnaire. The empirical findings revealed that the material import restrictions imposed by the government, price increments in materials due to restrictions, disruptions in machinery operations due to scarcity of fuel, rising labour costs, and shutdowns in government-funded projects are the main reasons for the projects to be abandoned during the economic crisis. Encouraging foreign investments, controlling inflation and keeping on track of the country’s economy, easing tight import restrictions, and proper pricing mechanisms for construction materials are some of the remedies proposed to avoid projects being abandoned during the crisis. The research findings deliver valuable evidence to the practitioners with an in-depth understanding of the remedies to take over during a period of a crisis and thereby minimize the projects being abandoned.

Infrastructure development can be identified as a key driver of economic growth. Most developing countries have prioritised implementing new procurement arrangements to execute public infrastructure projects throughout their life cycle efficiently. Private Public Partnership (PPP) procurement arrangement is one of the popular procurement arrangements, which can be classified as solicited proposals (SPs) and unsolicited proposals (USPs). Most countries have adopted USP for infrastructure projects among those two arrangements. Nevertheless, USPs have several drawbacks than SPs, such as corruption, low social and economic benefits, low value for money, and lack of transparency. However, governments are still developing their infrastructure projects as USPs due to the government's motivational aspects towards them. Therefore, it is controversial how those motivations have a huge impact than drawbacks in implementing USPs. Thus, this study aims to investigate the motivation for implementing USPs specific to the Sri Lankan context. Accordingly, a qualitatively based extensive literature synthesis has been conducted concerning the practices of USPs. Following the qualitative approach, data were collected through twelve (12) semi-structured interviews with industry professionals familiar with USPs implementation. The findings revealed that governments often choose USPs due to limitations in their capacity to identify and evaluate large-scale projects. These limitations can be financial and technical, including a lack of expertise. While speculation exists about corrupt practices associated with unsolicited PPPs, it is difficult to validate such claims. However, it is acknowledged that unsolicited PPPs, in their current state, offer higher opportunities for corruption. Nonetheless, accessing private financing quickly and efficiently for PPPs is also a positive motivation for choosing the unsolicited approach.

Therefore, it is controversial how those motivations have a huge impact than drawbacks in implementing USPs. Thus, this study aims to investigate the motivation for implementing USPs specific to the Sri Lankan context. Accordingly, a qualitatively based extensive literature synthesis has been conducted concerning the practices of USPs. Following the qualitative approach, data were collected through twelve (12) semi-structured interviews with industry professionals familiar with USPs implementation. The findings revealed that governments often choose USPs due to limitations in their capacity to identify and evaluate large-scale projects. These limitations can be financial and technical, including a lack of expertise. While speculation exists about corrupt practices associated with unsolicited PPPs, it is difficult to validate such claims. However, it is acknowledged that unsolicited PPPs, in their current state, offer higher opportunities for corruption. Nonetheless, accessing private financing quickly and efficiently for PPPs is also a positive motivation for choosing the unsolicited approach.","PeriodicalId":221447,"journal":{"name":"11th World Construction Symposium - 2023","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116898638","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}
