The whole world is utilizing its all-non-renewable energy sources to power their social, economic, and cultural needs. Hence, the significance of renewable energy is considered all around the world at this moment. Especially compared to other renewable energy sources, solar energy shows more reliable and available in the whole world. As a result, the cleanest solar energy makes a huge contribution to the global energy balance. To power the grid with solar energy all countries around the world expanding their technologies related to solar power generation. Accordingly, the net metering concept becomes a platform to inject and strengthen the grid with solar energy. However, some conventional methods such as NCRE power generation facility, DC-AC inverter, and islanding protection system are used to expand the grid-connected solar net metering in Sri Lanka. Therefore, it is required to improve the newly applicable solar net metering expansion strategies. Hence, this study aims to propose suitable strategies for the increment in the application of grid power solar net metering in Sri Lanka. A qualitative research approach was selected to conduct this study. Initially, a literature review was completed. Then, data is collected through semi-structured expert interviews with 4 experts, who have experience and engagement in the solar industry. The collected data were analyzed through manual content analysis. Findings revealed the key driving forces and the barriers to expanding the grid power solar net metering in Sri Lanka. With regards to the identified barriers, the newly applicable strategies have shown a significant amount of importance in Sri Lanka to expand the grid power net metering concept.

The construction industry is becoming more circular by reducing waste, reusing building materials, and embracing regenerative solutions for energy generation and biodiversity conservation. The ramifications of circularity on building operations are complicated, necessitating a comprehensive assessment of the consequences before deciding on the best course of action. In addition, professionals need to perform diversified services in achieving Circular Built Environment (CBE). Thus, the investigation of the involvement of Quantity Surveyors (QSs) with the CBE is important in achieving the CBE during the Design stage. Hence, the study aimed at investigating the role of QSs in achieving a CBE. The research apprehends a qualitative approach inclusive of two expert interview rounds adhering to the Delphi technique and manual content analysis for data analysis. The research findings revealed the important roles of QS in achieving CBE at the Design stage. Accordingly, cost control, cost planning, feasibility studies, measurement and quantification, risk management, value engineering and innovations and technologies were highly agreed upon by the majority of interviewees as important roles of QS during the Design stage.

Attribute to the rapid expansion of the built environment, excessive resource consumption and waste generation aligned with the corresponding linear economy practices have impacted the preservation of the ecosphere. In addressing the shortcomings of the linear economy, the circular economy concept was introduced by prioritising the circular value streams of the resources which minimises resource extraction and waste generation. However, environmental concerns are often disregarded in construction processes where the priority is given to the cost and economic return of construction applications. Simultaneously, the absence of a proper methodology in assessing the economic aspects of circular economy principles is apparent in the built environment sector. Therefore, this study aimed to assess the importance of a proper value assessment tool in shifting to a circular built environment in Sri Lanka. Instigating from a literature survey, the existing knowledge on the study area was synthesised. A qualitative approach was followed in the empirical study where semi-structured interviews were conducted with ten experts in the field of circular economy in Sri Lanka. The manual content analysis technique was followed in analysing the collected qualitative data. The findings revealed that the extremely low maturity of circular economy practices in the Sri Lankan construction sector is mainly caused by the absence of a proper value assessment tool. Therefore, the introduction of a proper value assessment tool is important for circular built environment experts to encourage the fellow construction community towards the transition to a circular built environment in Sri Lanka.

The need to ensure construction workers have good mental health is imperative because poor mental health has an economic cost that impacts individuals, companies, and nations. The aim of this study is to evaluate construction workers' mental health during the COVID-19 pandemic in Nigeria. To achieve this aim, a survey questionnaire was developed and administered online to building environment professionals working on construction sites. The results show that stress, feeling overwhelmed, feeling unusually confused, fatigue, being unpredictable and anxiety were the top mental health challenges during the COVID-19 pandemic. The result also revealed that training on mental health and the symptoms, awareness week activities, flexible working, and working from home policies were the top support provided by organisations for mental health wellbeing during COVID-19. The study concludes that difficulty in adapting to the challenges brought about by the deadly virus and its effect on the economy makes construction workers more susceptible to mental health challenges as it impaired their work life and thereby increasing their mental pressure.

A wealth of studies has demonstrated the significance of adequate or quality housing on occupant’s productivity, performance, comfort and health. However, insufficient data on the conditions of existing housing stocks and a lack of consensus measures of housing quality hinder housing developments from achieving residential needs. Due to the lack of quality indicators, the quality of housing is not often assessed. Therefore, this paper presents a systematic review using the PRISMA protocol to provide an overview of the housing quality indicators that can be employed to evaluate housing quality. The review consisted of 62 studies investigating 66 housing quality indicators. Each fall into one of eight categories, namely 1) dwelling unit architectural design characteristics and features; 2) user comfort; 3) housing site location and neighbourhood; 4) building services; 5) construction quality and stability; 6) economic aspect; 7) building maintenance; or 8) sustainability. The results show that investigating housing quality indicators is a growing research field where adequate ventilation was the most critical indicator of a quality home. Since the identified indicators are essential determinants of a quality house, architects and engineers can integrate these features at the design and construction stages in upgrading the conditions of dwellings while satisfying occupant’s comfort and quality of life. Further, governments can develop housing quality standards or regulations using these indicators to improve the quality of new housing constructions.

severely due to the Corona Virus Disease (COVID-19) pandemic. Unbalance of the Irontriangle which refers to key Construction Project Goals (CPG) (i.e., time, cost, and quality) is one of the phenomena that can be addressed while Sustainable Development (SD) (i.e., economic, social, and environmental sustainability) has been streamlined to worse condition. Even though, sustainability must be prioritised in developing countries e.g., Sri Lanka, where significant construction works are currently underway, especially during this situation. Further, the appropriate construction and implementation in a construction project can make a dramatic contribution to the mandate of sustainable development. Hence, this research intends to investigate how the Iron triangle would be unbalanced during the new-normal situation where it has a significant impact on SD simultaneously. A qualitative survey strategy was used to achieve the research aim. A semi-structured interview survey was conducted to solicit the perception of experts. Nine experts were selected purposively, who had experience in both Sustainable Construction (SC) and project management, especially proceedings during the new-normal condition. To analyse the empirical data, the manual content analysis method was used. As the decisive outcome, the ‘Iron-star’ model was developed by merging the Sustainable triangle and Iron-triangle which pertained to the interrelation between SD and Construction Project Goals (CPG). Initially, interrelations between SD measures and CPG were cogitated by literature findings. Economic depletion, health-related issues, supply chain disruption, and cash flow issues were identified as interventions to achieve CPG through SD measures. Further, it revealed that the Iron-star can implement as the way forward for the construction industry in the Sri Lankan (SL) context.

The construction industry is increasingly under pressure to improve environmental performance and reduce environmental degradation, which often results from carbon emissions and a high volume of waste generated from unprecedented levels of development associated with urbanisation and industrialisation. Construction projects consume a significant amount of water at the same time; they generate liquid waste (LW) from several wet processes during construction on-site, which is often unmetered. At the same time, LW or wastewater generated from construction projects is detrimental to the environment and human health, adversely polluting the surface and groundwater as well as the ground soil. It is, therefore, indispensable to manage LW appropriately while utilising the water efficiently. Limited studies have paid attention to explore the importance of effective liquid waste management (LWM) practices in construction projects and their implications on environmental sustainability. This study aimed to investigate the current practices of LWM in construction projects through the analysis of expert user views and quantitative data analysis while providing an account of LWM related legislative requirements. Moreover, this study estimated the average volume of water consumed for tool washing and water saving for different types of projects and compared it against the use of sustainable LWM systems, notably a closed-loop washout system employed in construction projects. The outcome of this study has the potential to add new and under-measured factors to the current LWM systems and to promote sustainable LWM practices in construction projects. While it highlights issues related to LWM, it provides criteria that can be considered for the green rating of buildings.

COVID-19 pandemic affected people in many ways. To prevent the spread of the virus, governments-imposed travel restrictions. This became the main reason for many sectors to adopt work from home (WFH) concept. Although WFH grew prominently with the COVID-19 pandemic, it was already practiced in several sectors even before the pandemic. However, there was lack of evidence regarding the quantity surveyor’s practice in WFH. This research therefore attempts to investigate how the quantity surveyors WFH during COVID-19 pandemic and factors that affected the successful functioning of their job. To achieve the aim, a mixed method research approach was undertaken. Initially, a comprehensive literature review was carried out and an interview guideline was developed as the data collection instrument. Subsequently, 30 semi-structured interviews were conducted to collect data. Collected qualitative data was analysed through code-based content analysis using NVivo 10 and quantitative data was analysed by using descriptive statistical analysis. Results shows that nature of job role, personal qualities, technology, organization related factors, gender, home-work interface, and economic condition of the country affects the QS’s function during WFH. Further, age, location of home, weather condition, job experience and performance of other employees were identified as factors that have a potential to affect QSs during WFH.

Post Disaster Reconstruction (PDR) projects are currently facing many issues. The highly demanding construction process of PDR projects that involves a number of different and well-coordinated courses of action can be simplified through integrating lean construction. Hence, Lean Iceberg Model (LIM) implementation for PDR projects will eventually minimise the issues in PDR projects. However, there is lack of research on implementation of lean construction to PDR projects. Therefore, this study aims to develop a framework to minimise PDR issues through LIM. This research adopted interpretivism stance and uses the qualitative survey strategy. Semi-structured interviews were conducted with ten experts, selected based on purposive sampling. The code-based content analysis was used to data analysis, which was supported by NVivo12. The findings of the study revealed that lack of quality, lack of budget and delays as the main issues in PDR projects. The essential part, therefore, was to identify invisible elements which were most of the times neglected rather than the visible elements of LIM. Finally, a framework was developed by systematically mapping the identified PDR issues for both visible and invisible elements of the LIM. In addition, the "LIM for PDR" mobile application has been developed as part of the framework which deals with educating and guiding users on a successful implementation of lean in a PDR project through LIM. The results of this research contribute to overcome the PDR issues which can be derived from the LIM. Hence, industry practitioners can use the outcomes to successfully implement lean in PDR projects.

A maturity model is critical in analysing an entity as it evaluates the current situation and provides insights on enhancing the capabilities to reach higher maturity. Maturity models are being used in many industries and proven to have a positive impact on organisational development. Definition of a context specific maturity model is vital as it brings clarity to the model identification and better understanding relevant for a respective industry. Even though several construction maturity models exist, a clear and a comprehensive definition is not noticeable. A comprehensive definition for maturity models in construction sector would assist industry stakeholders to understand the components and key areas of construction maturity. Consequently, it would provide accurate and impactful results for construction firms to achieve higher maturity levels. Thus, the main aim of this paper is to establish a new definition for construction maturity models. In the process, the methodology included a systematic literature review adopting PRISMA literature review method and a content analysis using thematic analysis. The study analysed fifteen construction maturity models and identified nine overarching themes which were fundamental in developing the definition. The proposed definition would facilitate a better understanding among end users of construction maturity models, and it would assist the readers to distinguish it from other various models. Therefore, the derived definition would promote application of the concept of construction maturity in the industry. Further research could be conducted for diverse types of construction to enhance the effectiveness of the maturity models.

Maturity models are being used in many industries and proven to have a positive impact on organisational development. Definition of a context specific maturity model is vital as it brings clarity to the model identification and better understanding relevant for a respective industry. Even though several construction maturity models exist, a clear and a comprehensive definition is not noticeable.
