Supporting zero-waste building: A novel spatial explicit material flow analysis model for construction waste

The accurate quantification of construction waste (CW) is prerequisite for achieving zero-waste in the building sector. This study employs a Spatial Material Flow Analysis model considering building life cycle to estimate the spatio-temporal dynamics of CW in Nanjing, China, over two decades. Additionally, it employs an ARIMA model for forecasting CW generation over the forthcoming decade. During 2000 to 2020, Nanjing's CW witnessed a CW increase from 0.8 to 59.0 Tg, predominantly comprising non-metallic materials. Meanwhile, the spatial distribution of CW has widened, accompanied by the emergence of numerous CW hotspots, in parallel with economic and population growth. Future projections suggest a continuous yet decelerating increase in CW generation, highlighting a significant opportunity for resource recovery. The application of this hybrid approach not only enhances CW management accuracy but also supports the broader goal of fostering sustainable building practices. This research expects to enlighten the stakeholders committed to advancing sustainable construction and waste management strategies in the context of zero-waste buildings.

Enhancing a circular economy for construction and demolition waste management in China: A stakeholder engagement and key strategy approach

China's construction and demolition waste has been substantially increasing due to the country's urbanization. However, since the recycling rate of construction and demolition waste is still much lower in China compared to most developed countries, its construction industry still relies heavily on natural resource consumption and is very much a linear economy. Although a circular economy for construction and demolition waste management has been promoted by the government in recent years, the transition from open-ended to close-looped circularity for construction and demolition waste management strategies have not been fully investigated. This study therefore identifies stakeholder engagement and closed-loop key strategies as part of a circular economy for construction and demolition waste management in China. Integrated approaches are used to achieve the aim of this study including literature review, semi-structured interview, questionnaire survey, and causal loop diagram development. The stakeholder engagement and key strategies were identified through literature review, semi-structured interviews, questionnaire survey, and statistical analysis. A causal loop diagram was then developed to demonstrate the interconnection and causal effect between stakeholders and key strategies. The findings reveal that stakeholder engagement and key strategies are highly interrelated for achieving closed-loop construction and demolition waste management. Government ranks as the most important stakeholder engagement, and improving secondary material quality and value is the most important key strategies. This study provides insights for practitioners and academics alike to help understand the interrelationship between stakeholder engagement and key strategies as part of a circular economy for construction and demolition waste management in China.

Cascading failure mechanism of major drainage system in mountainous city: Taking the basin of the main urban area of Chongqing as an example, China

Failure of major drainage systems is almost always accompanied by waterlogging. Understanding the operation and failure mechanism of major drainage systems is an important prerequisite for understanding and managing waterlogging. The natural and artificial environments in mountainous cities are more complex, and the major drainage system, as an open system for excessive surface runoff discharge and storage, is more prone to local overload and cascading failure. Existing theories and methods are difficult to explain and analyze the cascading failure characteristics and principles of major drainage systems in mountainous cities. Based on the complex network technology and the principle of runoff balance, the cascade failure model of major drainage system was constructed, and the characteristics and laws of cascade failure under six kinds of terrain, six kinds of short duration rainstorm and two kinds of surface environments were quantitatively analyzed. Research has found that the cascading failure of major drainage systems and waterlogging in mountainous cities should be the same phenomenon from different perspectives, and the simulated matching degree between the two can reach 79.5%. Meanwhile, 456 potential waterlogging locations were discovered in the study area, which is much larger than the actual 73 locations. When urban construction and rainfall conditions change, these unstable potential waterlogging locations are easily apparent. Among them, terrain is the main factor restricting the cascading failure of major drainage systems. Low lying valley areas often quickly accumulate a large amount of overflow, while flat areas are prone to overflow spreading to the surrounding areas; Slope areas are not prone to overflow, but are prone to local flooding. The change of short duration rainstorm and the difference of surface environmental openness will further interfere with the cascade failure of the major drainage system. The longer the return period of the short duration rainstorm or the increase of the peak value of the rainfall pattern, the greater the discharge and storage pressure of the major drainage system per unit time, resulting in intensified waterlogging. The open and unobstructed surface environment will lead to the small-scale spread of waterlogging, but this will significantly reduce the overall degree of waterlogging in the late rainstorm. The study revealed the spatiotemporal principles and basic laws of cascading failure of major drainage systems in mountainous cities. The conclusion is helpful for mountainous cities to formulate urban construction management strategies and climate change adaptation strategies, and to cope with current and future potential waterlogging disasters.

Innovative solution: soil cement column walls as a temporary retaining structure for excavation in soft Bangkok clay

The installation of temporary retaining walls for excavation activities is considered a crucial and costly aspect in the realm of geotechnical engineering construction. Several past studies have been undertaken on the stability aspects of the deep mixing method for soil–cement column walls in soft Bangkok clay are available. However, there has been a lack of research focusing specifically on the relationship between execution time, cost, and stability of these walls, a topic on which this study is focused. The principal aim of this research was to investigate and make a comparative analysis of the stability, construction cost, and construction duration of retaining walls under varying construction site conditions. This study placed particular emphasis on shallow excavation conducted in the context of soft Bangkok clay, and its focus was to determine the most effective construction management strategies within the given contextual parameters. The investigated wall systems comprised of soil–cement columns (SC), stiffened soil–cement columns (SSC), and sheet pile walls. The SC had a diameter of a diameter of 0.6 m, while the SSC was composed of an embedded steel pipe with a diameter of 0.2 m (SSC-IRow Wall). The stability of the walls under investigation was assessed through the utilization of finite element (FE) simulation. The finite element model was initially calibrated through a comparison between the simulation results and the data obtained from field measurements. For a 4.5 m deep excavation with a required factor of safety > 1.3, the SCC and SSCC Walls were found to have an advantage over the conventional sheet pile wall. The SC Wall, consisting of two rows and measuring 7 m in length, demonstrated superior efficiency in terms of both time and cost, regardless of whether it was implemented in unconfined or confined construction sites. The utilization of the SSC-IRow Wall was suggested as an alternative in cases where the use of a thick SC Wall was prohibited. A systematic approach for the selection and design of the SC and SSC Wall systems was proposed, drawing upon a thorough examination and evaluation of the study findings. The results of this study possess the capacity to be utilized in excavation endeavors encompassing diverse depths in the context of soft Bangkok clay and comparable soil conditions.

Sustainable construction strategies for building construction projects in the Kingdom of Bahrain: a model

Sustainability is defined as meeting the demands of the present without compromising the ability of future generations to meet their own needs. This study focuses on the sustainable construction strategies used in the Kingdom of Bahrain in terms of sustainable construction technologies and management strategy linked to the environment and the significant relationship between the management strategy and construction technologies used for sustainable building construction. This study employed the descriptive-correlational method of research using a questionnaire for gathering data about the sustainable construction strategies used in Bahrain. The data gathered were analyzed using the weighted mean and Pearson’s correlation coefficient to determine the degree of correlation between construction technologies and management strategy. SPSS software was used in the calculation. Results show that management strategy linked to the environment is often practiced in around 75% of all projects delivered while general sustainable construction methods, energy and material-based techniques, and waste-based techniques are sometimes utilized in around 50% of all the building projects delivered. In addition, the utilization of these sustainable construction technologies is the result of a management strategy linked to the environment which the respondents rated as often practiced for all projects that were delivered. This implies that management strategy in protecting the environment in Bahrain is often practiced in construction for 75% of the projects. From the results of the study, a model of sustainable building construction in the Kingdom of Bahrain was derived to achieve sustainable building construction. This includes the management strategies needed by the different stakeholders like construction firms and government agencies to carry out the implementation of sustainable construction and sustainable construction techniques (e.g., waste management, insulating materials, building envelope with thermal properties, building management system, and efficient fixtures).

Applying the Tier II Construction Management Strategy to Measure the Competency Level among Single and Multiskilled Craft Professionals

Various contemporary studies have revealed a heightened need for the implementation of effective strategies to reduce labor shortages in the construction industry. The subsequent investigation outcomes have identified multiskilling labor strategies as viable solutions to alleviate labor deficiencies in the construction sector. These strategies aim to train single-skilled craft professionals so that they can acquire different skills and complete tasks in addition to their primary duties in the workplace; however, limitations exist in terms of measuring competency levels among single-skilled and multiskilled craft professionals. Thus, a workforce management strategy, referred to as Tier II strategy metrics, is used in this study as a comprehensive approach to evaluate the construction workers’ competency levels among more than 2740 workers in the industry. Furthermore, multinomial logistic regression was applied to explain the variability in both the project craft technical and project craft management Tier II score. The overall average Tier II score for multiskilled workers was 6.27, whereas single-skilled workers scored 5.17. The results show that multiskilled craft professionals have higher competency levels compared with single-skilled craft professionals. The outcome from the regression model demonstrates that craft workers who are experts and multiskilled are competent in terms of their project craft technical skill, and years of experience is the most important variable for predicting high competency levels.

Integration of the green and lean principles for more sustainable development: A case study

To advance sustainable development techniques, this study examines how lean construction and green building might work together at all stages of project development. The construction sector is now dealing with a variety of issues, including cost overruns, completion delays, low productivity, and subpar quality. These underlying issues must be addressed to bring about a general change and improvement in the existing state of the construction industry. Only a lean construction and lean project management strategy can address the demand for transformation. The 4 R's—Reduce; Recycle, Reuse, and Regulate—are causing people to become concerned. Eliminating the “idea of waste” and fostering a healthy environment via design and management have recently emerged as major objectives, bringing sustainability in building into focus. Through case studies, the attempt to link green and lean ideas is implemented in a successful way. The report would highlight the close ties between the lean and green ideologies, both of which aim to cut down on waste. It would investigate how a green and sustainable built environment is produced in the building sectors.

Current construction and demolition waste management strategies for Philippine construction sector – A systematic literature review

The construction industry continues to be one of the primary drivers of a country's economic progress. As of 2022, the Philippines’ construction sector had an annual growth rate of 9.2% and continues to increase due to the Build! Build! Build! (BBB) program. However, the construction sector is globally known for regularly consuming more raw materials, resulting in natural resource scarcity and environmental implications. Construction activities also generated a massive volume of construction waste from construction, demolition, and renovation. The need to impose construction and demolition waste (CDW) management strategies and policies in all stages of construction is crucial in attaining a more sustainable construction. This study aims to explore the current CDW management practices and policies from existing literature. The findings of this research will present many potential strategies and solutions that the Philippines can adopt to create more sustainable construction while also assisting in combating environmental issues and concerns in attaining sustainable construction. The study will utilize a Systematic Literature Review (SLR) to identify relevant studies in CDW management to gain the best practices and current trends in CDW management. The study's findings show that at least 26 strategies have been implemented in the construction industry. These can be grouped into 6 major groups: information technology, policy, design, operations, knowledge, and procurement based.

Disputes and Claim Management during the COVID-19 Crisis: The Lessons Learned

The COVID-19 crisis has presented the construction sector with challenges that the world has never seen before. Productivity is down, costs have increased, conflicts and claims are increasing, delays are high, health and safety practices are increasing, and profit margins have been reduced. The challenges require unprecedented, sudden, and unplanned changes to construction management practices and strategies. Through an open-ended survey questionnaire, this research investigated how COVID-19 causes disputes in construction projects and the measures that quantity surveying firms take to resolve the disputes in construction contracts due to the pandemic. The data revealed that disputes and claims have increased by some 80% due to the COVID-19 pandemic. In addition, the data revealed that the COVID-19 pandemic has increased project costs by more than 40%. Shortages of materials, compliance with standard operating procedures, social distance, fluctuation, and shortages of labor are the causes of disputes. Unlike prior to the COVID-19 crisis, disputes are not caused by variations, ambiguous contract clauses, mistakes, errors, and competencies of the parties to the contracts. To resolve COVID-19-induced claims, contract clauses, negotiations, conciliation, trust management, and contingency provisions are the most effective. This research provides new information on claim management during a crisis. From an ontological standpoint, the main findings of this study are generalizable to construction projects in and outside of Nigeria.

Study the delays and conflicts for construction projects and their mutual relationship: A review

Delays and conflicts (D&Cs) are adversely affecting the performance of construction projects. They have separately been addressed by many authors but the mutual relationship among them is still a key grey area. Therefore, this study aims to explore this hidden relationship. Literature was reviewed to identify the previous ranking of D&Cs causes to develop a global ranking and to explore other hidden aspects of mutual relationships. Data were classified through Jenks optimization that resulted in the identification of, the top five causes of D&Cs in a global perspective and commonality among them. Among the top five identified global causes of D&Cs, the common causes are; (1) financial problems on behalf of the owner, (2) Change orders/ Variations, and (3) Lack of communication/ Poor relationship. Such exploration of hidden relationships among D&Cs will not only improve construction management strategies but will also define new pathways for future research to secure project success parameters.

Impact of concrete waste management by using life cycle assessment

The rapid expansion of Dubai and the United Arab United infrastructure in the Middle East over the past twenty years has resulted in a large accumulation of concrete waste in landfills and dumping sites. The subsequent hasty increase in the construction and demolition of the infrastructure has outstripped effective waste management facilities, posing a serious natural challenge. This concrete waste greatly endangers human health, property, and biological systems when buried. To find effective solutions to this issue, different waste management methods were researched and compared to find the most effective. This paper aims to differentiate the most appropriate waste management strategies and determine their impact on the environment. These methods included reducing the waste, reusing those wastes that can be reused, recycling, and disposal in landfills and government dumping sites. This paper opens the door for future studies to determine the impact indicators and specific waste management methods that substantially influence the environment and the cost of damage. In addition, a Life Cycle Cost Assessment (LCA) may be carried out to supplement this research and determine the financial benefits of the various specific waste management options and the cost of damages. The study predominantly assesses the different construction and demolition waste management strategies. It primarily adds valuable knowledge concerning these waste recycling management techniques and their environmental effect. This study also suggests directions for future exploration, such as identifying key impact indicators and management strategies that have a significant impact on the environment. Alternatively, LCA can complement the results by assessing the financial benefits of different physical waste management options. To sum up, the exponential growth of infrastructure in Dubai has led to a considerable challenge regarding concrete waste. The LCA-based comparison between landfill and recycling methods highlights the urgency of adopting sustainable waste management practices. This study not only broadens the understanding of damage cost models but also provides a comprehensive assessment of practical waste management options, contributing to informed decision-making to minimize environmental impact.
