Authors: Klungseth Nora Johanne , Nielsen Susanne Balslev , Alves Da Graça Moacyr Eduardo , Lavy Sarel 
Published: December 2022

Abstract
Standards for products, processes and management systems are important tools for the much-needed sustainable transformation of the built environment. With standards, we refer to documents coming from standardisations bodies such as ASTM/ANSI (USA), BSI (UK), CEN (Europe), and ISO (global). The purpose is to investigate the role standards play in current research to exemplify various ways CIB and standardisation bodies can combine efforts for a sustainable transformation of the built environment (BE). Scientific journal articles were identified though literature review. The paper focuses on the building’s use and operation phase and especially the new Facility Management (FM) standards (ISO 41000 series) developed by the technical committee ISO/TC267. Our findings are based on a closer analysis of 10 journal articles from 2010-2021 after identifying 198 relevant articles. The articles refer to a broad range of standards which proves the relevance of standards in building research. There are no proves of how research has influenced standards, only examples of research aiming to enhance standards. Improving and implementing international FM standards is a driver to improve the BE sustainability. CIB and the standardisation bodies have an important role to accelerate the societal transition processes and contributing to society’s demands of sustainability and resilience.

Abstract
When planning to build greenways in jungles, accurate topographic information of the target area is significant. The traditional topographic survey is usually manually conducted with several tools, which is not only labour-intensive and time-consuming, but also has limitations in accuracy and efficiency. Therefore, this paper presents a method to generate a digital elevation model based on unmanned aerial vehicle (UAV) and ground equipment supplements the ground area covered by vegetation where UAV-based equipment cannot reach. Iterated Closest Point (ICP) is first used to register the point cloud data from UAV and ground mobile equipment. Then, point cloud classification is used to non-ground point cloud. Finally, the digital elevation model and contour line are obtained. A real experiment is conducted to validate the presented method. The results show that this method not only overcomes the UAV’s limitation of having difficulty in collecting point cloud data from the covered area, but also realizes large-area point cloud data collection that ground mobile equipment cannot. Compared with the traditional base station and multi-person assistance measurement, the presented method is more efficient and effective.

Authors: Yao G , Sun W T , Yang Y 
Published: December 2022

AbstractIn order to reduce the number of building construction accidents (BCA) and ensure construction activities safety, investigators analyzed BCA in China with recent representative 10 year data. Firstly, the investigators collected BCA information in the research period, determined accident trend and pattern in various dimensions. The development of safety management strategies for tower crane accidents (TCA) and collapse accidents (CA) was essential for construction safety control. Secondly, the investigators collected major construction accident (MCA) information in China in the research period, established AHP models for TCA and CA respectively. The second-level accident causes of the AHP model can provide targeted evaluation feedforward factors for quantitative checklist. Finally, the investigators formulated an audit method for TCA management measures and CA prevention management measures. It was found that there were specific trend and pattern in the occurrence of BCA, such as hourly trend, monthly trend, annual trend, regional pattern, type pattern, and cross pattern. Two MCA, TCA and CA, were screened out in this study. The corresponding feedforwards were obtained by analyzing the MCA.
A Socio-Technical System (STS) Framework for Modular Construction of Cognitive Buildings
Authors: Ghansah F A , Lu W , Chen J , Peng Z 
Published: December 2022

Abstract
The cognitive building provides promises if its social and technical requirements are considered holistically, but these have not been consciously explored, particularly within modular construction, which offers an unexploited opportunity. This study, therefore, aims to develop a framework for the modular construction of a cognitive building as a socio-technical system to ensure effective human-technology interaction, stakeholder acceptance and engagement. The framework is examined with a mock-up project of a student smart residential building in Hong Kong, similar to a cognitive building, which adopted a modular construction technique. The case demonstrated that the framework effectively ensures multi-perspectival involvement of key stakeholders at the design and manufacturing phase to produce modular units cleanly embedded with appropriate and operable cognitive building technologies for users and facility managers before transported to the site. The study is based on a single case study; hence, there could be a little scientific rigour providing little basis for the generalisation of the results to a wider space. As buildings are technologically advancing, future studies are encouraged to look at other possible case projects that utilise modular construction principles and evaluate them by adopting this study’s STS framework or its enhanced form.

Authors: Ferraro C , Esposito M A 
Published: December 2022

Abstract
This contribution investigates research opportunities in the field of architecture and design management focusing on user health in high traffic spaces. The field of application is Airport Passenger Terminals. Looking at the COVID-19 pandemic and anticipating the possibility of events of the same magnitude, it is necessary to approach the problem of the safety in public spaces. Based on the State of the Art about antimicrobial material studies, Science of Architecture could propose innovative solutions that are compliant with health safety and prevention for high-use surfaces. These solutions will combine antimicrobial materials with a digital solution that could manage data about surfaces, allowing the maintenance team to valuate and optimize operations. After few hours the hygiene level of copper-based surfaces is higher than any other material. Copper-based furniture could be paired with sensors that send data to management software. Combining the use of scientifically demonstrated antibacterial surfaces with high-performance management tools could be the best option to achieve health safety and contribute to social sustainability. Airport terminals are the ideal high-traffic buildings to use as test model because they have all the characteristics that could be analysed concerning the safety and the perception of safety of architectural spaces by users.
The Application of the Best Value Approach in Purchasing Card Services
Authors: Kashiwagi Jacob , Kashiwagi Dean 
Published: December 2022

Abstract
A US State’s Office of State Procurement (OSP) was seeking to procure Commercial Card services. The OSP was challenged with a lack of competition in previous procurements. The OSP identified that the vendor centric approach of the Best Value Approach (BVA) would improve the result of their procurement. OSP enlisted the help of the Performance Based Studies Research Group (PBSRG) to identify how to integrate the BVA into their current process. PBSRG identified the States’s procurement approach as client centric. The State and PBSRG ran the BVA to procure the State’s Commercial Card program showing that the vendor centric approach did not require the client to be an expert in the service they were procuring. The results showed that the State was able to attract more vendors to bid on their service, increased the value of the service and minimized the time and effort of the OSP in procuring the service. The State did not implement the project management component of the BVA.

Published: December 2022

Abstract
Construction industry is currently facing challenges such as a high number of occupational injuries and a somewhat weak connection between design and construction phases. One way to amend the situation is to increase data availability to construction professionals. Information about the structure and features of the building to be built should be shared so that various professionals can use the so-called digital twin model of the building for his/her purposes. We have created a concept for delivering the building information model (BIM) that can be viewed in various ways from various devices. We tested the viewing and using of BIM in augmented reality (AR), with high-end eXtented Reality (XR) technology (Microsoft HoloLens 2) and a tablet. Briefly, according to our test results, AR seems to be good when user needs to be perceived him/herself as if inside the building model, and tablet suits for viewing the digital model from the outside of it. Novice users of the AR technology need much more support in using the technology than the experienced ones. All test participants found the concept good and the technology with which to use it as promising.

Authors: Chen X , Chang-Richards A 
Published: December 2022

Abstract
New and emerging technologies such as digital technologies and new construction techniques have altered the way buildings are designed and constructed. However, to what extent they are practically implemented in the construction sector remains unknown. By employing a qualitative interview approach, this study attempts to examine the current status and perceived benefits of technology implementation in the New Zealand construction industry. The results manifest high adoption rates of technologies for basic design, group collaboration, and data visualisation, acquisition and management. Benefits of improvements in work efficiency, productivity, quality, and health and safety are highly appreciated by the interviewees as being primary. The findings of this study contribute to an improved understanding of the practical needs, trends and motivations for technology adoption among construction organisations in New Zealand. Such knowledge and understanding can inform the decision making of government agencies and industry body organisations in facilitating technology adoption, allocating resources for effective technological transformation in the sector.
Implementing and Sustaining the Best Value Approach in an Organization
Authors: Kashiwagi Joseph , Kashiwagi Dean 
Published: December 2022

Abstract
In recent years, construction companies have lost millions of dollars due to poor project management performance on projects. The Best Value Approach (BVA) is one of the only documented systems to show an increase in the performance of project management. It has been used on over 2000 projects with a 98% customers satisfaction to cut costs, decrease time, reduce effort, and improve quality on projects. The BVA system is also the most licensed technology at Arizona State University with 65 licenses. The issue with the BVA is that professionals have struggled to implement and sustain the system in their own organizations. Research was conducted at SKEMA Business School as part of a Doctor of Business Administration (DBA) to resolve the sustainability issue. The research included a complete literature review of the BVA and 32 other buyer/supplier systems along with a practitioner’s survey (107 participants) and 10 test projects from a large organization that has been utilizing the BVA for over three years. The result of the study is 11 unique BVA characteristics, 6 identified issues by practitioners, and 15 modifications to improve the sustainability of the BVA. The research provides a foundational framework for how organizations can implement and sustain the BVA that has been tested and used with a large organization.
An investigation into the relationship between diversity, leadership and innovation in the South African construction industry
Authors: Madikizela K , Michell K 
Published: December 2022

Abstract
Without a diverse leadership and workforce, in the South African construction industry innovation is hindered and slowed, resulting in a weakened ability to respond to a fast paced and technologically driven market and economical changes, which has a direct impact on organisational growth. Little is known about the role of leadership in managing the relationship between diversity and innovation in the South African construction industry. The construction industry has not been responsive to market changes and therefore slow to innovate. This rapidly evolving contextual landscape requires a more diverse workforce in order to address these challenges. This paper presents the findings from a study that investigated and analysed the role of leadership in managing the relationship between diversity and innovation in the construction industry. In this context leadership is described as the ability to select, equip, train, and influence one or more followers who have diverse gifts, abilities, and skills and focuses the followers to the organisation’s mission and objectives. Diversity are described as age, ethnicity, cultural background, gender, race and capabilities. Innovation is described as the implementation of ideas that have come together to create new solutions to problems or improvements to existing systems, processes, products, or attempted solutions.
Profit factors in real estate projects: A comparison of academic studies and expert opinions
Authors: Fazilet M B , Artan D 
Published: December 2022

Abstract
Primary goal of private real estate investment projects (REIPs) is to make profit. Therefore, REIP profitability is a critical performance indicator. This study identifies and compares the determinants of profit in REIPs in the academic literature and the industry. Firstly, 191 profitability factors are identified and categorized by an in-depth review of the literature over the period of 2000-2019 in the selected databases and journals on construction, real estate and economics. Secondly, a final set of 66 factors from the literature are constructed based on the frequency analysis and using the normative refinement technique. Finally, face to face interviews are conducted with 15 senior managers working in the Turkish real estate and construction sector to validate the factors identified with the comprehensive literature review. Consequently, 96 REIP profit factors were obtained from the industry. The comparative analysis of the literature review and expert opinions shows that beside the prevalent similarities, experts focus more on design related factors, previous project records, value engineering, testing and commissioning, and the work environment. The benefits of this study are twofold: (i) helping professionals to understand the factors required to control profitability in REIPs, (ii) providing an extensive list of profitability factors for future researchers.

Published: December 2022

Abstract
The construction industry is one of the most dangerous sectors with poor safety performance. With recent technological developments, Unmanned Aerial Vehicles (UAV) are demonstrating the potential to be a valuable innovation to improve construction safety. To date, several studies have been conducted to evaluate the applications of UAV for safety in the construction industry. In order to systematically assess the research status on UAV to improve construction safety, this research investigated published journal articles (in English) within the Scopus database to determine the current research gaps and future work suggested by the publications. Thirty-three articles and reviews were included in the study. The analysis revealed a positive trend in publications in this area. Publications were also analysed based on the country of origin of the research and the journal. Prototype and experiments were identified as the most frequently used research methods. The majority of the studies, irrespective of the type of construction, focused on the construction stage. Where health and safety aspects were concerned, the use of UAV for visualisation and identification of hazards were found to be the most frequent applications. Some research gaps and recommendations for future research are also discussed in the paper

Published: December 2022

Abstract
Prefabrication construction has gained popularity in the construction industry during the last few years. Due to the complexity of prefabrication design, building information modelling (BIM) is adopted in the design stage to improve efficiency and accuracy. Many previous studies have examined the adoption of BIM in the design stage and explored the current practice of BIM adoption in prefabrication construction, however fewer first-hand investigations are made on assessing the adoption of BIM. This study aims to identify the opportunities and challenges of utilizing BIM technology in the design stage of prefabrication construction from the perspective of designers. A semi-structured interview was conducted for qualitative data collection and the data are analysed by thematic analysis. A total of eight designers from Chinese prefabrication construction projects were interviewed. The research identified 8 opportunities and 15 challenges of BIM adoption in prefabrication construction. The top four challenges are: (1) inaccurate prefabrication production drawings generated by BIM software, (2) late adoption of BIM in the design stage, (3) lack of communication platform for different designers, and (4) lack of sharing the updated design model among designers, manufacturers, and onsite engineers. These findings provide directions for improving BIM adoption in the design of prefabrication construction.
Digital Twin based built environment asset management services development
Authors: Moretti N , Xie X , Merino Garcia J , Chang J , Kumar Parlikad A 
Published: December 2022

Abstract
The Digital Twin (DT) concept emerged recently in the Architecture, Engineering, Constructions and Operations domain and the interest for digital built asset management service implementations is increasing. However, most of the applications are developed according to custom approaches, preventing the generalisation and modularisation. This article presents a methodological framework for DT-based applications development. DT-based applications support effective data-centric processes in the management of critical assets. The proposed approach is based on a flexible and federated data model, enabling dynamic data management. The federated data model provides an interface and connection among different knowledge domains. The service requirement definition provides the input specification for the application development, accomplished through the modelling of three fundamental components: data, processes, and algorithms. These components are assembled through Application Programming Interfaces (APIs), supporting the DT-based services. The proposed approach is applied to the West Cambridge DT research facility and tested in the building energy sub-metering strategy. The developed approach allows flexible and interoperable data-centric applications development, contributing to the generalisation and scalability of DT-based built asset management applications. This aims at providing a consistent approach that can be employed in different domains, where the DT technologies play a central role in service innovation.
A BIM-based model to study wayfinding signage using virtual reality
Authors: Goupil V , Gouranton V , Michaud A S , Gauvrit J Y , Arnaldi B 
Published: December 2022

Abstract
Wayfinding signage is essential in a large building to find one’s way. Unfortunately, there are no methodologies and standards for designing signage. A good sign system therefore depends on the experience of the signage company. Getting lost in public infrastructures might be disorienting or cause anxiety. Designing an efficient signage system is challenging as the building needs to communicate a lot of information in a minimum of space. In this paper, we propose a model to study wayfinding signage based on BIM models and the BIM open library, which allows the integration of signage design into a BIM model to perform analyses and comparisons. The study of signage is based on the user’s perception, and virtual reality is a tool that best approximates this today. Our model helps to perform signage analysis in building design and to compare objectively the wayfinding signage in a BIM model using virtual reality.

Published: December 2022

Abstract
This study presents an institution-industry collaboration model for BIM training with a case study of a TVET college in Vietnam. The model focuses on the most needed and practical skills to fit with the actual requirements of the labour market. It also helps to educate BIM technicians that meet the industry standards in a reasonable training time. In consultation with the industrial partners, the College defined six learning outcomes and 18 competencies for the BIM program to ensure that students can perform the BIM technician job when finishing the program. The findings present the benefits of the collaboration training model that could provide a better learning environment for students and help to narrow the gap between educational outcomes and industry needs. Furthermore, a questionnaire survey was conducted targeting the industrial partners and graduated students to assess the importance of the designed competencies. Feedback from the participants shows that collaboration and self-development skills are the most critical skills for the BIM technicians, so the BIM program should develop related courses aligned with the learning outcomes.
