Purpose Dam industry projects have significant economic, social and environmental impacts. However, very little has been carried out to improve their lifecycle performance. The purpose of this study is to identify success criteria applicable to different stages of such projects. Design/methodology/approach This study adopted a quantitative research design where the potential success criteria for dam engineering projects were evaluated. The applicable success criteria were determined for the four phases of project lifecycle by three rounds of Delphi technique with the participation of experts from dams industry in Australia. Findings The findings of this research suggest that project success is a multidimensional notion and varies over lifecycle of projects. This study on project success criteria shows that certain criteria can be applied to measure success in different phases over lifecycle of Australian dam industry projects. Originality/value The results of this research present the first exclusive quantitative assessment of success criteria for dams industry. The success criteria presented in this study enable project practitioners to measure success at various stages of dam industry projects. This can serve as a tool to put more management efforts into achieving success on those criteria.

Purpose The reuse of timber building parts, when designing new buildings, has become a topic of increasing discussion as a proposed circular solution in support of sustainable development goals. Designers face the difficulty of identifying and applying different design strategies for reuse due to multiple definitions, which are used interchangeably. The purpose of this study is to propose a taxonomy to define the relationships between various concepts and practices that comprise the relevant strategies for reuse, notably design for disassembly (DfD) and design for adaptability (DfA). Design/methodology/approach Literature reviews were conducted based on research publications over the previous 12 years and located through the Web of Science and Scopus. Findings A taxonomy for the design process grounded on two strategies for reuse is presented: DfD and DfA. Based on previous work, the taxonomy aims to build a vocabulary of definitions in DfD and DfA to support other researchers and practitioners working in the field. Research limitations/implications The research is limited to the design phase of timber-based buildings. It does not take into account the other phases of the construction process, neither other kind of construction methods. Practical implications The application of the taxonomy can facilitate communication between different actors and provide a way for building product manufacturers to demonstrate their reuse credentials, enabling them to produce and promote compliant products and thereby support design for reuse strategies. Social implications This paper could contribute to a closer collaboration of all stakeholders involved in the building process since the very early phases of the conceptual design. Originality/value This paper contributes a comprehensive taxonomy to support the deployment of circular reuse strategies and assist designers and other stakeholders from the earliest of phases in the building’s life cycle. The proposed definition framework provided by the taxonomy resolves the longstanding lack of a supporting vocabulary for reuse and can be used as a reference for researchers and practitioners working with the DfD and DfA.

Purpose Modern human society has continuous advancements that have a negative impact on the quality of the air. Daily transportation, industrial and residential operations churn up dangerous contaminants in our surroundings. Addressing air pollution issues is critical for human health and ecosystems, particularly in developing countries such as Egypt. Excessive levels of pollutants have been linked to a variety of circulatory, respiratory and nervous illnesses. To this end, the purpose of this research paper is to forecast air pollution concentrations in Egypt based on time series analysis. Design/methodology/approach Deep learning models are leveraged to analyze air quality time series in the 6th of October City, Egypt. In this regard, convolutional neural network (CNN), long short-term memory network and multilayer perceptron neural network models are used to forecast the overall concentrations of sulfur dioxide (SO2) and particulate matter 10 µm in diameter (PM10). The models are trained and validated by using monthly data available from the Egyptian Environmental Affairs Agency between December 2014 and July 2020. The performance measures such as determination coefficient, root mean square error and mean absolute error are used to evaluate the outcomes of models. Findings The CNN model exhibits the best performance in terms of forecasting pollutant concentrations 3, 6, 9 and 12 months ahead. Finally, using data from December 2014 to July 2021, the CNN model is used to anticipate the pollutant concentrations 12 months ahead. In July 2022, the overall concentrations of SO2 and PM10 are expected to reach 10 and 127 µg/m3, respectively. The developed model could aid decision-makers, practitioners and local authorities in planning and implementing various interventions to mitigate their negative influences on the population and environment. Originality/value This research introduces the development of an efficient time-series model that can project the future concentrations of particulate and gaseous air pollutants in Egypt. This research study offers the first time application of deep learning models to forecast the air quality in Egypt. This research study examines the performance of machine learning approaches and deep learning techniques to forecast sulfur dioxide and particular matter concentrations using standard performance metrics.

Purpose Construction safety is a crucial aspect that has far-reaching impacts on economic development. But safety monitoring is often reliant on labor-based observations, which can be prone to errors and result in numerous fatalities annually. This study aims to address this issue by proposing a cloud-building information modeling (BIM)-based framework to provide real-time safety monitoring on construction sites to enhance safety practices and reduce fatalities. Design/methodology/approach This system integrates an automated safety tracking mobile app to detect hazardous locations on construction sites, a cloud-based BIM system for visualization of worker tracking on a virtual construction site and a Web interface to visualize and monitor site safety. Findings The study’s results indicate that implementing a comprehensive automated safety monitoring approach is feasible and suitable for general indoor construction site environments. Furthermore, the assessment of an advanced safety monitoring system has been successfully implemented, indicating its potential effectiveness in enhancing safety practices in construction sites. Practical implications By using this system, the construction industry can prevent accidents and fatalities, promote the adoption of new technologies and methods with minimal effort and cost and improve safety outcomes and productivity. This system can reduce workers’ compensation claims, insurance costs and legal penalties, benefiting all stakeholders involved. Originality/value To the best of the authors’ knowledge, this study represents the first attempt in Bangladesh to develop a mobile app-based technological solution aimed at reforming construction safety culture by using BIM technology. This has the potential to change the construction sector’s attitude toward accepting new technologies and cultures through its convenient choice of equipment.

Purpose The purpose of this study is to investigate the benefits and challenges of implementing circular economy (CE), as well as shed light on the influence of procurement strategy in CE implementation in construction projects. Design/methodology/approach A qualitative research approach with abductive reasoning was adopted. The empirical data were collected from the construction industry in the United Arab Emirates (UAE). Findings The results reveal that clients, consultants and contractors have limited awareness, knowledge and motivation to implement CE in construction projects. The absence of incentives to design projects following CE principles, lack of involvement of contractors and suppliers, non-use of materials that use CE principles and current procurement strategies are the main challenges for the implementation of CE in the UAE. Originality/value Previous research offers limited knowledge on CE and its implementation in construction projects particularly from a procurement strategy perspective. The findings of the study provide new knowledge of the benefits, challenges and role of procurement strategy for implementing CE. It is suggested that collaborative and partnering-based procurement methods are needed to facilitate the effective implementation of CE.

Purpose Design for adaptability and disassembly (DfAD) is an effective method to reduce construction and demolition waste generation, landfill loads and greenhouse gas generation; preserve natural resources; and increase environmental awareness in the construction industry. However, it is an underexplored strategy due to a lack of information about projects and a set of agreed guidelines to guide buildings deconstruction. This study aims to understand how DfAD can support the sector’s transition toward circularity. Design/methodology/approach Through an integrative literature review, this study analyzed the current publications and terminologies used, identified the main themes discussed and described the key criteria for integrating deconstruction in the building design stage. Findings The results showed that the term DfAD encompasses different ecodesign strategies and is concentrated in six major thematic categories (design and construction principles, tools for DfAD, components and connections for DfAD, barriers, drivers and guidelines for DfAD, existing building stock potential and selective deconstruction process). In total, 60 criteria were presented to guide the deconstruction of buildings, emphasizing standardization, modularization and prefabrication of materials and components as fundamental requirements. Originality/value The study highlighted the need to expand the knowledge and training of the design team, establish public policies and tax incentives and develop tools, methods, and circular indicators to enable the implementation of deconstruction strategies for buildings.

Purpose This study aims to explore the innovation deployment of construction contracting firms through exploratory–exploitative learning and organisational ambidexterity. Design/methodology/approach Firstly, a literature-based conceptual framework was developed to explain innovation implementation through exploratory–exploitative learning and organisational ambidexterity. A prominent Hong Kong construction contracting firm was then selected as the case study to explore its innovation deployment at different organisational levels (i.e. firm and project levels). Qualitative data were attained by conducting 12 semi-structured interviews with industry experts and document analysis. The thematic analysis using NVivo 12 software was adopted to analyse data. Findings Findings reveal that the case study firm successfully fosters innovation when ambidexterity is achieved through the balance between exploratory (i.e. radical innovation) and exploitative learnings (i.e. incremental innovation). Research limitations/implications Establishing uniform ambidexterity (i.e. 50:50) at the firm or project level is not mandatory to deploy innovation successfully. The ratio can vary based on the characteristics and requirements of construction firms. Practical implications This paper shall motivate construction practitioners to adopt radical–incremental innovation ambidexterity in firms and ultimately enhance the productivity and efficiency of the construction industry. Originality/value Previous construction innovation research has frequently explored firm or project-level innovation separately. This study identified a multi-level focus on innovation. Through the lens of exploratory–exploitative theory, different forms of innovation ambidexterity for different levels are suggested rather than one specific ambidexterity.

Purpose This study aims to build on a contextualised approach for revealing the particularities of social sustainability indicators on the building scale within the particular context of Jordan, focusing on the buildings of the Dahiyat Al Hussein suburb. Design/methodology/approach This study relied on a review of the relevant previous research as well as global, regional and local rating tools, followed by working with a diversified participant base comprising experts as well as users through Delphi rounds and analytic hierarchy process-based assessments. Findings This study resulted in several key indicators that were classified into three main categories: environmental friendliness, comfort and convenience and social blend. It resembled a step on the path towards the standardisation of context-specific social sustainability indicators, an effort that would be further supported by future research addressing other development within Jordan. Originality/value The sustainability debate has, for long, acquired the undivided attention of its key stakeholders. With the continuous rise of global attention, the conceptualisation of sustainability has grown more specialised in both function and scale, and sustainable measures have been developed at the macro and micro levels. With the further spread of the concept, recognition of its contextual differences between various countries became more vivid, where the social dimension attains particular importance.
目的本研究旨在基于情境化方法，揭示约旦特定背景下建筑规模上的社会可持续性指标的特殊性，重点关注Dahiyat Al Hussein郊区的建筑。设计/方法论/方法本研究依赖于对相关先前研究以及全球、区域和地方评级工具的审查，然后通过德尔菲轮和基于层次分析法的评估，与包括专家和用户在内的多元化参与者群体合作。研究结果本研究得出了几个关键指标，分为三大类：环境友好性、舒适便利性和社会融合性。这类似于在实现特定环境的社会可持续性指标标准化的道路上迈出的一步，约旦未来针对其他发展的研究将进一步支持这一努力。独创性/价值长期以来，可持续性辩论一直受到主要利益相关者的关注。随着全球关注度的不断上升，可持续性的概念在功能和规模上都变得更加专业化，并在宏观和微观层面制定了可持续措施。随着这一概念的进一步传播，各国对其背景差异的认识变得更加生动，社会层面变得尤为重要。

Purpose Building defects are becoming recurrent phenomena in most high-rise buildings. However, little research exists on the analysis of defects in high-rise buildings based on data from real-life projects. This study aims to develop dashboards and models for revealing the most common locations of defects, understanding associations among defects and predicting the rectification periods. Design/methodology/approach In total, 15,484 defect reports comprising qualitative and quantitative data were obtained from a company that provides consulting services for the construction industry in Victoria, Australia. Data mining methods were applied using a wide range of Python libraries including NumPy, Pandas, Natural Language Toolkit, SpaCy and Regular Expression, alongside association rule mining (ARM) and simulations. Findings Findings reveal that defects in multi-storey buildings often occur on lower levels, rather than on higher levels. Joinery defects were found to be the most recurrent problem on ground floors. The ARM outcomes show that the occurrence of one type of defect can be taken as an indication for the existence of other types of defects. For instance, in laundry, the chance of occurrence of plumbing and joinery defects, where paint defects are observed, is 88%. The stochastic model built for door defects showed that there is a 60% chance that defects on doors can be rectified within 60 days. Originality/value The dashboards provide original insight and novel ideas regarding the frequency of defects in various positions in multi-storey buildings. The stochastic models can provide a reliable point of reference for property managers, occupants and sub-contractors for taking measures to avoid reoccurring defects; so too, findings provide estimations of possible rectification periods for various types of defects.
目的建筑缺陷正在成为大多数高层建筑中反复出现的现象。然而，很少有研究基于真实项目的数据来分析高层建筑的缺陷。本研究旨在开发仪表盘和模型，以揭示最常见的缺陷位置，了解缺陷之间的关联，并预测整改周期。设计/方法/方法总共从一家为澳大利亚维多利亚州建筑业提供咨询服务的公司获得了15484份缺陷报告，包括定性和定量数据。数据挖掘方法使用了广泛的Python库，包括NumPy、Pandas、Natural Language Toolkit、SpaCy和Regular Expression，以及关联规则挖掘（ARM）和模拟。调查结果显示，多层建筑的缺陷往往发生在较低的楼层，而不是较高的楼层。细木工缺陷被发现是底层最常见的问题。ARM结果表明，一种类型缺陷的发生可以作为其他类型缺陷存在的指示。例如，在洗衣房中，发现油漆缺陷的管道和细木工缺陷发生的几率为88%。针对车门缺陷建立的随机模型表明，车门上的缺陷在60秒内得到纠正的可能性为60% 天。独创性/价值仪表盘提供了关于多层建筑中不同位置缺陷频率的独创见解和新颖想法。随机模型可以为物业经理、住户和分包商提供可靠的参考点，以采取措施避免缺陷再次发生；研究结果也为各种类型的缺陷提供了可能的整改周期的估计。

Purpose The construction industry shows an increased interest in how to manage logistics within construction projects. Often construction logistics is outsourced to a logistics service provider (LSP). However, construction logistics is normally approached either as a strategic decision or as an operational issue and rarely as a tactical concern. The purpose of this study is to explore how to organize the logistics outsourcing decision at strategic, tactical and operational levels. Design/methodology/approach This study is performed as a single-case study within a construction corporation, containing (amongst others) a building contractor (BC) and a construction equipment rental company (CERC) offering logistics services. Findings The study shows that to procure construction logistics service successfully, BCs need logistics capabilities at strategic and tactical levels to maintain an alignment between the use of logistics services and operational characteristics. Simultaneously, CERC’s need to design their service offerings to correspond to the needs of the BC. Research limitations/implications This study builds on a single-case study of a Swedish construction corporation. Further research is needed to better understand current logistics outsourcing and development practices and how these can be improved to foster better logistics management at the project level. Practical implications BCs find suggestions of different logistics organization structures and suitable outsourcing arrangements. CERCs and LSPs can use the findings to understand their customers’ needs and adapt service offerings. Originality/value To the best of the authors’ knowledge, this study is one of the first studies of how two companies within a corporation can work together to develop construction logistics service offerings.
