The construction industry is shifting towards becoming more circular by reducing waste, reusing building materials and embracing regenerative solutions for energy generation and biodiversity conservation. Thus, construction professionals must perform diversified services to achieve a circular built environment (CBE). Implementing resource planning and waste management in CBE has already posed challenges to the quantity surveying profession; thus, quantity surveyors (QSs) should be equipped with new roles and competencies to tackle challenges in achieving a CBE. Hence, this study aimed to investigate the functions and competencies of QSs at the design and building material sourcing stages in achieving a CBE according to 3R principles.

The research apprehended a qualitative approach, including two expert interview rounds adhering to the Delphi technique with 14 and 11 experts per each round. Manual content analysis was incorporated to analyse the collected data.

The research findings revealed the important roles and competencies of QSs in achieving a CBE. In addition, essential functions and competencies were categorised according to the 3R principles (reduce, reuse, recycle) to successfully implement CBE during the Design and Building Material Sourcing stages. According to the 3R principles of CBE, cost control, cost planning, feasibility studies, measurement and quantification, risk management, value engineering and innovations and technologies were well-received by most interviewees as essential roles of QSs during the Design and Building Material Sourcing stages. Further, basic/mandatory competencies (personal, interpersonal, professional practice and business skills), economic analysis, BIM management, cost management and risk management are highly regarded by experts for QS as important competencies to achieve CBE.

With new construction trends, QSs must enhance their conventional roles and competencies and search for new skills and competencies. Those skills and competencies could be linked to the CE concept, either directly or indirectly. Since QS holds a prominent place in sustainable construction in CBE, adapting to changes in the construction industry such as CBE is timely for QSs. Further, there is a shortage of literature regarding QSs' roles and competencies in achieving a CBE; thus, this study will contribute by identifying new avenues for QSs in achieving a CBE in the practice and the research.

Construction material management is an important process in supporting construction operations that affect project performance. Previous studies attempt to identify factors influencing material management in different stages such as procurement, transportation and utilization. However, they lack a model to explain the relationship between influential factors and the effectiveness of material management. Therefore, this study aims to validate the variables and key factors influencing the effectiveness of material management processes.

A total of 42 variables were reviewed from literature in different stages of material management process. Survey questionnaires were used to collect data about participants' perceptions on these variables. The respondents were 200 project engineers and project managers from construction sites and offices in Vietnam. Then factor analysis techniques were undertaken to validate the structure of factor groups. Two methods of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were, respectively, performed to evaluate and verify the model's fit.

Factors influencing the effectiveness of material management were grouped into nine main factors, which are procurement issues, site conditions, planning and handling on site, industrial environments, contractual issues, quality control, suppliers and manufacturers' issues, transportation in and out site and security on site.

The paper has several implications for theory and methodology related to material management. It features influential factors in association with the material management effectiveness. Therefore, senior managers can more fully understand the errors in their works and propose timely solutions to limit the unwanted risks.

This research contributes on theoretical development on factors influencing effectiveness of material management processes. The key findings on influential factors can be applied to measure the effectiveness of material management processes.

This study aimed to determine the expectations of students from mathematics teachers in the planning phase of lesson study (LS) in mathematics classrooms.

This study reported only a part of large-scale action research. The participants were Grade 8 students selected by the convenience sampling method. The data were obtained through open-ended questions. The content analysis method was used to analyze the data.

Four categories emerged: connection, technology-supported teaching, use of concrete materials, practice, and teacher behavior and teaching style.

This study reveals how students in a different culture and education system, such as Türkiye, want to learn mathematics in the LS process of Japanese origin. It also gives some important clues for applying LS in a different culture.

This study may attract the attention of educational stakeholders who want to implement LS in mathematics classrooms by considering student perspectives.

Due to the nature of LS, this study may emphasize teacher–student and teacher–teacher interactions. Thus, it can draw attention to the importance of social learning environments where students take responsibility and interact.

This study emphasizes the importance of listening to student voices in LS. Some ideas about mathematics teaching in Turkey should also be given. Finally, it can provide a good basis for understanding and comparing LS practices in different cultures and understandings.

The unstable labor productivity and periodic planning method cause barriers to improving construction logistics management. This paper aims to explore a demand-driven mechanism for efficient construction logistics planning to record the material consumption, report the real-time demand and trigger material replenishment from off-site to on-site, which is aided by Building Information Modeling (BIM) and the Kanban technique.

This paper follows the design science research (DSR) principles to propose a system of designing and applying Kanban batch with 4D BIM for construction logistics planning and monitoring. Prototype development with comparative simulation experiments of a river remediation project is conducted to analyze the conventional and Kanban-triggered supply. Two-staged industrial interviews are conducted to guide and evaluate the system design.

The proposed BIM-enabled Kanban system enables construction managers and suppliers to better set integrated on- and off-site targets, report real-time demands and conduct collaborative planning and monitoring. The simulation results present significant site storage and schedule savings applying the BIM-enabled Kanban system. Feedback and constructive suggestions from practitioners are collected via interviews and analyzed for further development.

This paper brings to the limelight the benefits of implementing BIM-enabled demand-driven replenishment to remove waste from the material flow. This paper combines lean production theory with advanced information technology to solve construction logistics management problems.

By reconsidering the concept of the historic environment, the aim of this study is to better understand how heritage is expressed by examining the networks within which the cultural performances of the historic environment take place. The goal is to move beyond a purely material expression and seek the expansion of the cultural dimension of the historic environment.

Conceptually, the historic environment is considered a valuable resource for heritage expression and exploration. The databases and records that house historic environment data are venerated and frequented entities for archeologists, but arguably less so for non-specialist users. In inventorying the historic environment, databases fulfill a major role in the planning process and asset management that is often considered to be more than just perfunctory. This paper approaches historic environment records (HERs) from an actor network perspective, particularizing the social foundation and relationships within the networks governing the historic environment and the environment's associated records.

The paper concludes that the performance of HERs from an actor-network perspective is a hegemonic process that is biased toward the supply and input to and from professional users. Furthermore, the paper provides a schematic for how many of the flaws in heritage transmission have come about.

The relevance here is largely belied by the fact that HERs as both public digital resources and as heritage networks were awaiting to be addressed in depth from a theoretical point of view.

Green building (GB) maintenance is increasingly accepted in the construction industry, so it can now be interpreted as an industry best practice for maintenance planning. However, the performance competency and design knowledge of the practice's building control instrument process can be affected by its evaluation and the information management of building information modelling (BIM)–based model checking (BMC). These maintenance-planning problems have not yet been investigated in instances such as the Grenfell Tower fire (14 June 2017, approximately 80 fatalities) in North Kensington, West London.

This study proposes a theoretical framework for analysing the existing conceptualisation of BIM tools and techniques based on a critical review of GB maintenance environments. These are currently employed on GB maintenance ecosystems embedded in project teams that can affect BMC practices in the automation system process. In order to better understand how BMC is implemented in GB ecosystem projects, a quantitative case study is conducted in the Malaysian public works department (Jabatan Kerja Raya (JKR)).

GB ecosystem projects were not as effective as planned due to safety awareness, design planning, inadequate track insulation, environmental (in) compatibility and inadequate building access management. Descriptive statistics and an ANOVA were applied to analyse the data. The study is reinforced by a process flow, which is transformed into a theoretical framework.

Industry practitioners can use the developed framework to diagnose BMC application issues and leverage the staff competency inherent in an ecosystem to plan GB maintenance environments successfully.

The purpose of this study is to develop an integrated model for the stochastic multiproject scheduling and material ordering problems, where some of the prominent features of offshore projects and their environmental-degrading effects have been embraced as well. The durations of activities are uncertain in this model. The developed formulation is tri-objective that seeks to minimize the expected time, total cost and CO₂ emission of all projects.

A new version of the multiobjective multiagent optimization (MOMAO) algorithm has been proposed to solve the amalgamated model. To empower the MOMAO, various procedures of this algorithm have been modified based on the multiattribute utility theory (MAUT) technique. Along with the MOMAO, this study has employed four other meta-heuristic methodologies to solve the model as well.

The outputs of the MOMAO have been put to test against four other optimizers in terms of convergence, diversity, uniformity and computation times. The results of the Mean Ideal Distance (MID) metric have revealed that the MOMAO has strongly prevailed its rival optimizers. In terms of diversity of the acquired solutions, the MOMAO has ranked the first among all employed optimizers since this algorithm has offered the best solutions in 56.66 and 63.33% of the test problems regarding the diversification metric and hyper-volume metrics. Regarding the uniformity of results, which is measured through the spacing metric (SP), the MOMAO has presented the best SP values in more than 96% of the test problems. The MOMAO has needed more computation times in comparison to its rivals.

A real case study comprising two concurrent offshore projects has been offered. The proposed formulation and the MOMAO have been implemented for this case study, and their effectiveness has been appraised.

Very few studies have focused on presenting an integrated formulation for the stochastic multiproject scheduling and material ordering problems. The model embraces some of the characteristics of the offshore projects which have not been adequately studied in the literature. Limited capacities of the offshore platforms and cargo vessels have been embedded in the proposed model. The offshore platforms have spatial limitations in storing the required materials. The vessels are also capacitated and they also have limited shipment capacities. Some of the required materials need to be transported from the base to the offshore platform via a fleet of cargo vessels. The workforces and equipment can become idle on the offshore platform due to material shortage. Various offshore-related costs have been integrated as a minimization objective function in the model. The cargo vessels release CO₂ detrimental emissions to the environment which are sought to be minimized in the developed formulation. To the best of the authors' knowledge, the MOMAO has not been sufficiently employed as a solution methodology for the stochastic multiproject scheduling and material ordering problems.

This study assessed the antecedents and consequences of tourists’ authenticity experience in a new ancient town in China. Based on Chinese cultural background and case study, this paper aims to explore this kind of tourism place making and establishes an empirical model to examine and verify the impact of tourists’ perception, authentic experience and behavioral tendency on such place making, and proposes targeted improvement measures.

Based on a Chinese cultural background and case study, this paper explored a certain kind of tourism place making and established an empirical model to examine and verify the impact of tourists’ perceptions, authentic experiences and behavioral tendencies on such place making; the goals were to try to create a new scale to measure the authenticity of the “new ancient town” in the Chinese context and to propose targeted measures for improvement.

Research shows that Chinese visitors acquire experiences that they perceive to be authentic when visiting a contrived attraction such as a new ancient town. The dimensions of cultural, functional, product, value and unique authenticity were identified as distinct dimensions of tourists’ authenticity experiences in a new ancient town. Although these dimensions have been mentioned at times in the context of traditional Western assessments of authenticity, they do not replicate exactly any category of Western objective authenticity, existential authenticity, constructive authenticity or postmodern authenticity. They instead constitute an authentic experiential dimension in a typical oriental context, which is comprehensively explicated by combining the image of a national cultural theme and the elements of functional construction created by tourist places in a new ancient town.

This study explored the path relationship among perception of place making – authenticity experience – behavioral intention, but it did not analyze relationships among the dimensions of perception of place making or among the authenticity experience variables. Furthermore, advantage was not taken of the availability of socioeconomic information to look for differences among interviewees with different attributes. In addition, there is a profound cultural and complex theoretical connotation to authenticity in the Chinese context, and the study of a single case is insufficient to fully elucidate meaning in this emerging discourse.

By verifying the path of tourists’ authenticity experiences through the perception of place making, the understanding of the effects of different elements of place making on tourists’ experiences is refined. For space producers, different elements of place making promote tourists’ authenticity experiences to different degrees. Strengthening the construction of the physical environment, marketing and scenes can promote tourists’ authenticity experiences: planning and design, marketing and scene enhancements promote tourists’ functional authenticity experiences; planning and design, the physical environment and marketing enhance tourists’ product authenticity experiences; planning and design, marketing, the physical environment and scene enhancement can improve tourists’ perceptions of value; unique authenticity experiences can be created in the marketing and scenes in new ancient towns.

Certain aspects of the space production in new ancient towns can be used to strengthen tourists’ perceptions of value. First, the scene system at scenic spots can be strengthened, catering to tourists’ visual, olfactory and other senses so that they are available in all kinds of weather. Second, the local cultural characteristics of the material environment can be strengthened and the installation of inappropriate cultural symbols can be avoided. Thus, a physical environment that is of local ethnic cultural significance can be created so that both local residents and tourists can perceive the value of the place. Third, the rational layout of the new ancient towns should be established and maintained through the ongoing involvement of professional planning and design teams. Local cultural attributes that are of national significance should be included in the layout and design of the physical environment. Fourth, daily marketing and management actions influence how tourists influence scene value. Therefore, managers of scenic places need to make prudent decisions about and integrate local folk and ethnic characteristics into their marketing, which can promote the sustainable development of tourism effectively (Saarinen, 2018).

First, this study constructed and validated the model and path relationship of the “perception of place making, authentic experience, and behavioral intention,” and it confirmed that the perception of place making had an important impact on tourists’ authentic experiences. Second, the exploratory factor analysis extracted five dimensions of the tourist authenticity experience (i.e. cultural, functional, unique, product and value authenticity) based on China’s context of ming shi, which enriched the connotations of the authenticity experience. Third, this study effectively linked the perception of place making with the real experience and behavioral intention of tourists and expanded the theoretical research boundary of place making to a certain extent.

本文以中国文化背景和案例研究为基础, 对“新古镇”旅游的地方营造进行了探讨, 并建立了实证模型。利用SPSS 23.0和Smart PLS 3.0进行数据分析, 检验和验证游客在类似场所的地方营造感知、真实体验和行为意向的路径关系。

以现代技术手段再造（创造）遗产旅游目的地已经成为一个全球性的现象。本文基于中国的文化背景和案例, 考察和验证了游客对地方营造的感知、真实性体验和行为意向的影响, 尝试创造一种新的尺度来衡量在中国语境下“新古镇”的真实性内涵, 并以此提出了针对性的改善措施。

研究表明, 中国游客在参观新古镇等人造景点时, 会获得他们认为真实的体验。文化真实、功能真实、产品真实、价值真实和独特真实是新古镇游客真实性体验的不同维度。它们构成了一个典型东方语境下的真实性内涵, 全面阐述了一个民族文化主题形象与新古镇旅游地方营造功能建设要素的结合。

本研究探讨了地方营造知觉-真实性体验-行为意向之间的路径关系, 但未分析地方营造感知各维度之间及真实性体验变量之间的关系。此外, 没有利用社会经济信息的可用性来寻找不同属性受访者之间的差异。此外, 在中国语境中, 真实性有着深刻的文化内涵和复杂的理论内涵, 仅对单个案例的研究不足以充分阐明这一新兴话题的意义

对于空间生产者来说, 加强物理环境、营销和场景的建设可以促进游客的真实体验:规划设计、营销和场景的增强可以促进游客的功能真实体验;规划设计、物质环境、营销提升游客的产品真实性体验;规划设计、营销、实体环境和场景提升可以提升游客的价值感知;在新古镇的营销和场景中应创造独特的真实性体验。

新古镇地方营造的某些方面可以提升游客的价值感知。首先, 通过迎合游客的视觉、嗅觉和其他感官, 加强景区的场景系统。其次, 可以创造一个具有当地民族文化意义的物质环境, 使当地居民和游客都能感受到这个地方的价值。第三, 通过专业规划设计团队的持续参与, 建立和维护新古镇的合理布局。第四, 日常营销和管理行为影响游客的价值体验。

首先, 本研究构建并验证了“地方营造感知、真实体验与行为意向”的模型和路径关系, 证实了地方营造感知对游客真实体验的重要影响。其次, 基于中国语境, EFA提取了旅游真实性体验的五个维度(文化真实、功能真实、独特真实、产品真实和价值真实), 丰富了真实性体验的内涵。第三, 本研究将游客的地方营造感知、真实体验和行为意向进行了有效地连接。

Basándose en un contexto cultural chino y en un estudio de caso, este artículo exploró la creación de lugares turísticos en la “nueva ciudad antigua” y estableció un modelo empírico. Se utilizaron SPSS 23.0 y Smart PLS 3.0 para el análisis de datos, con el fin de examinar y verificar la relación entre las percepciones de la creación de lugares, las experiencias auténticas y las intenciones de comportamiento de los turistas en dichos lugares.

La recreación moderna de lugares como atracciones turísticas patrimoniales es un fenómeno mundial. Partiendo de un contexto cultural chino y de un estudio de caso, este artículo examina y verifica el impacto de las percepciones de los turistas, las experiencias auténticas y las tendencias de comportamiento en dicha creación de lugares; los objetivos eran intentar crear una nueva escala para medir la autenticidad de la “nueva ciudad antigua” en el contexto chino y proponer medidas específicas de mejora.

La investigación muestra que los visitantes chinos adquieren experiencias que perciben como auténticas cuando visitan una atracción artificial como una nueva ciudad antigua. Las dimensiones de autenticidad cultural, funcional, de producto, de valor y única se identificaron como dimensiones distintas de las experiencias de autenticidad de los turistas en una nueva ciudad antigua. Éstas constituyen una auténtica dimensión experiencial en un contexto típicamente oriental, que se explica de forma exhaustiva combinando la imagen de un tema cultural nacional con los elementos de construcción funcional creados por los lugares turísticos de una nueva ciudad antigua.

Este estudio exploró la relación entre la percepción de la creación de lugares, la experiencia de autenticidad y la intención de comportamiento, pero no analizó las relaciones entre las dimensiones de la percepción de la creación de lugares, ni entre las variables de la experiencia de autenticidad. Además, no se aprovechó la disponibilidad de información socioeconómica para buscar diferencias entre entrevistados con distintos atributos. Adicionalmente, en el contexto chino, la autenticidad tiene profundas connotaciones culturales y teóricas complejas, y el estudio de un solo caso no basta para dilucidar plenamente la importancia de este tema emergente.

Para los productores de espacios, reforzar la construcción del entorno físico, el marketing y las escenas puede promover las experiencias de autenticidad de los turistas: la planificación y el diseño, el marketing y la mejora de las escenas promueve las experiencias de autenticidad funcional de los turistas; la planificación y el diseño, el entorno físico y el marketing mejoran las experiencias de autenticidad de los productos de los turistas; la planificación y el diseño, el marketing, el entorno físico y la mejora de las escenas pueden mejorar la percepción de valor de los turistas; se pueden crear experiencias de autenticidad únicas en el marketing y las escenas de las nuevas ciudades antiguas.

Ciertos aspectos de la creación de lugares en las nuevas ciudades antiguas pueden mejorar la percepción de valor de los turistas. En primer lugar, puede reforzarse el sistema escénico de los lugares de interés, atendiendo a los sentidos visuales, olfativos y de otro tipo de los turistas. En segundo lugar, se puede crear un entorno físico que tenga un significado cultural étnico local para que tanto los residentes locales como los turistas puedan percibir el valor del lugar. En tercer lugar, el trazado racional de las nuevas ciudades antiguas debe establecerse y mantenerse mediante la participación continua de equipos profesionales de planificación y diseño. En cuarto lugar, las acciones diarias de marketing y gestión influyen en la experiencia de valor del turista.

En primer lugar, este estudio construyó y validó el modelo y la relación entre la “percepción de la creación de lugares, la experiencia auténtica y la intención de comportamiento,” lo que confirmó la importante influencia de la percepción de la creación de lugares en la experiencia auténtica de los turistas. En segundo lugar, basándose en el contexto chino, el análisis factorial exploratorio extrajo cinco dimensiones de la experiencia de autenticidad turística (autenticidad cultural, funcional, única, del producto y del valor), que enriquecieron las connotaciones de la experiencia de autenticidad. En tercer lugar, este estudio vinculó eficazmente las percepciones de los turistas sobre la creación de lugares, con la experiencia real y con las intenciones de comportamiento de los turistas.

The purpose of this study is to get a clearer knowledge of the reasons for, approaches to and challenges associated with integrating sustainable development concerns into pipeline construction projects in New Zealand. To achieve this, this study delves deeply into sustainable construction to understand the reasons behind and incorporate sustainable development trials into their newly established product management and development procedure. As a result, this study looks at identifying key elements of sustainable construction practices and various interpretations of sustainability in the construction industry; offering a strategy for incorporating sustainable construction practices into the pipeline construction project in New Zealand; and benefits and difficulties that the construction industry encounters when implementing sustainable construction. Finally, a framework is developed to help in understanding the issues and potential solutions for integrating sustainable building methods into the pipeline construction project in New Zealand.

This study followed a four-step method (Figure 1), beginning with the identification of the data, continuing with the first screening of the data, determining eligibility and, finally, including the data. This data collection is being done to provide knowledge and direction for further research. Data were collected from various websites on the Web of Science and from Scopus databases. Additionally, data were gathered with the assistance of aggregator databases such as Scopus (scopus.com) and publishing databases such as Elsevier (sciencedirect.com), Inderscience, Taylor and Francis (tandfonline.com), Emerald Insight (emeraldinsight.com) and Google Scholar. These databases have been considered by a number of scholars to be reputable databases.

This research provided a thorough description of the key justifications for sustainable construction. This study demonstrated how the idea worked in practice by reviewing the literature on the relevance and analysis of sustainability in construction. This body of research identified crucial components of sustainable construction techniques and varied interpretations of sustainability in the construction industry. To better grasp the current application considerations in the construction sector, it also offered literature on sustainable construction methods. To determine the most effective strategy to make certain adjustments to the current construction processes, the literature also includes a wide range of sustainability-related topics in both developed and developing country contexts. This study also demonstrated the many perspectives and strategies for sustainable behaviors. Because the purpose of this study was to develop a strategy for implementing sustainable construction in New Zealand, it was of the utmost importance to shed light on the most well-known and prominent sustainable construction applications from across the world. The output of this aim provided the literature on construction practices to acquire insight into the ongoing conversations on sustainable practices and systems in the construction industry. This was done to obtain insight into the existing talks.

This research's contribution to the body of knowledge is demonstrated by the fact that this study has led to a better understanding of sustainable construction practices in the construction industry as well as the identification of the most significant challenges that businesses, organizations, educators and policymakers must face to improve their ability to put these strategies into practice. This research has provided a solid foundation for future research that aims to advance knowledge in this field by providing options for future research to evaluate the influence that the approach has had on enhancing the implementation of sustainable construction. Additionally, this study presents options for future research to evaluate the influence the approach has had on improving the implementation of sustainable construction. The successful completion of the research aim in the more traditional forms of higher education in the built environment can contribute to a better representation of new trends in the practice area associated with expanding and improving the construction industry sustainably.

The purpose of this review is to comprehensively consider the material properties and processing of additive titanium alloy and provide a new perspective for the robotic grinding and polishing of additive titanium alloy blades to ensure the surface integrity and machining accuracy of the blades.

At present, robot grinding and polishing are mainstream processing methods in blade automatic processing. This review systematically summarizes the processing characteristics and processing methods of additive manufacturing (AM) titanium alloy blades. On the one hand, the unique manufacturing process and thermal effect of AM have created the unique processing characteristics of additive titanium alloy blades. On the other hand, the robot grinding and polishing process needs to incorporate the material removal model into the traditional processing flow according to the processing characteristics of the additive titanium alloy.

Robot belt grinding can solve the processing problem of additive titanium alloy blades. The complex surface of the blade generates a robot grinding trajectory through trajectory planning. The trajectory planning of the robot profoundly affects the machining accuracy and surface quality of the blade. Subsequent research is needed to solve the problems of high machining accuracy of blade profiles, complex surface material removal models and uneven distribution of blade machining allowance. In the process parameters of the robot, the grinding parameters, trajectory planning and error compensation affect the surface quality of the blade through the material removal method, grinding force and grinding temperature. The machining accuracy of the blade surface is affected by robot vibration and stiffness.

This review systematically summarizes the processing characteristics and processing methods of aviation titanium alloy blades manufactured by AM. Combined with the material properties of additive titanium alloy, it provides a new idea for robot grinding and polishing of aviation titanium alloy blades manufactured by AM.
