SWOT Analysis of Offsite Manufacturers of Prefabricated Building Components in Singapore
Authors: Yng Ling Florence Yean , Jie Chia Jonathan Rong 
Published: December 2022

Abstract
Despite government’s push for the use of prefabrication in Singapore, the problem is that offsite manufacturers of prefabricated building components (hereinafter referred to as manufactures) appear to be unable to harness their inherent strengths, overcome their weaknesses and external threats to take advantage of the available opportunities in the construction market. The aim of this study is to do a SWOT analysis on Singapore’s manufacturers and develop strategies to enable them to thrive. A structured questionnaire was designed based on extant literature of offsite manufacturing. Quantitative data were collected from 46 project stakeholders via an industry wide survey. It was found that manufacturers’ strengths are their high quality prefabricated products and high productivity. Their weaknesses are the high capital and production costs. Their biggest opportunities are the limited supply of manual site labor and tender evaluation criteria that favour productivity and quality. The threats include lack of control over factors of production, shrinking construction demand, stiff competition and complex designs. The implication is that manufacturers should improve and re-examine their internal operations to overcome their weaknesses and the challenges in their external environment. Production should be streamlined, and partnerships with suppliers and transportation firms should be developed to guard against price fluctuations and inaccurate deliveries. Other recommendations are also offered to help manufacturers harness their strengths and opportunities while minimizing their weaknesses and threats.…
Quantifying Safety in Off-site Construction
Authors: Odo N , Rankin J 
Published: December 2022

Abstract
The construction industry has been identified as one of the most dangerous when examining safety performance and outcomes. The concept of leveraging off-site construction as a safer alternative to execute construction works has been presented by researchers and industry, but support for this premise with quantifiable data is lacking. To investigate differences in off-site construction versus conventional on-site methods, the research has developed a safety evaluation methodology to quantify safety performance and allow for comparisons of construction methods. The methodology is developed in partnership with a jurisdictional occupational health and safety authority and leverages historical safety data to provide inputs for a risk-based process-analysis of construction methods. The methodology is partially validated in collaboration with the project team (owner, general contractor, module manufacturer) and applied to a case study of a mid-rise modular hotel construction project that employed a mix of conventional and off-site construction processes. The evaluation methodology takes a construction product-focused approach (in this a case a hotel room module) with emphasis on defining a complete material supply chain. As such, the approach takes a unique approach to industry level comparison, establishing an evaluation methodology for future comparisons.

Published: December 2022

Abstract
Digital technologies are becoming increasingly wide-spread both in our personal and in our professional lives. This change has been evident also in the construction industry, although the industry has been identified as one of the least digitalised industry sectors. This research investigates how various digital technologies have become and are becoming part of construction management responsibilities. Construction management responsibilities have been identified through a document analysis as eight responsibility groups including management of time, cost, quality, health and safety, environmental factors, resources, and contracts, and development of human resources and processes. Construction management related digital technologies on the other hand have been identified through a document analysis and a systematic literature review and categorised under communication and other enabling technologies, technologies combining hardware and software in intelligent systems, and data technologies. The way how the construction management responsibilities and the digital technologies interlink forms a description of the modern way of performing construction management responsibilities. Some of the technologies are in everyday use across construction management professionals, however, many are at their pilot stage offering a perspective not just to the present but to the near future for the whole discipline.

Published: December 2022

Abstract
As the population in Victoria continues to grow, there has been a corresponding increase in building approvals across the State. Houses characterised as low-rise residential buildings often take the largest share of these approvals, with incessant residential building activities being driven by record low interest rates. Low-rise residential buildings comprise various building forms that use a number of specified construction materials to construct the building envelope and other structural and non-structural elements. As materials used for constructing residential building envelopes continue to evolve, these materials must be fit for purpose, and satisfy design criteria and performance requirements, while being aesthetically pleasing. This research analyses the trend in construction materials used in building envelopes of low-rise residential buildings using data from building permits issued between 1996 to 2019. The trend analysis shows that traditional double brick wall systems and suspended timber floors have reduced in popularity for houses built in the 21st century. The analysis also shows that brick veneer wall cladding systems built over slab-on-ground footings is the dominant construction form while the roof cladding material is influenced by geographical location. Insights from the data analysis indicate very little innovation has emerged in materials for residential building envelopes despite its crucial role in providing thermal comfort for inhabitants. Results from this research will serve as a basis to provide quantitative assessment of the trend in materials resource; provide insights about the impact of new building envelope products on existing industries; and perspectives on materials for future building envelopes.
A Survey of Phnom Penh Apartment Shophouses’ Conditions for Future Housing Adaptability Revitalization in Phnom Penh
Authors: Pengly K , Tirapas C 
Published: December 2022

Abstract
Phnom Penh, Cambodia, has planned to be one of the liveable and sustainable cities by improving the living quality of citizens. However, the new living developments (high-rise apartments, townhouses, office buildings) have ignored the neighbourhood living conditions (mixed use and dense) and caused urban gentrifications. Moreover, the study also shows that new generations prefer a good quality home design responding to needs and lifestyles. These address opportunities for pursuing living design solutions according to the policies, people’s preferences, and pain points of existing housing designs. A typical urban residential type in Phnom Penh is Apartment Shophouses. In the past, they were a row of two-story buildings located in city areas. The ground units were for business purposes, while the upper floors were for multi-family living accessing from a courtyard in the middle. Presently, the Apartment Shophouses have changed into a row of 5-6 story, diversified-use, and lively buildings. Nevertheless, they lack maintenance, poor daylight, and ventilation. According to the policies and residents’ preferences, these challenges for the Apartment Shophouses revitalization into an adaptable, lively neighbourhood and good lifestyle building for the new generations. The study investigates the living and adaptive conditions of the Apartment Shophouses from the 40 residents via online questionnaires and 10 residents via interviews. The results show weak conditions and opportunities for building with quality improvement based on the Open Building approach.

Abstract
The construction sector is India’s second-largest industry, contributing to the country’s economy and providing many job opportunities. However, construction has been described as a hazardous industry with a high rate of injuries, accidents, and fatalities compared to other sectors worldwide. The “psychological contract of safety (PCS)” is one of the safety climate (SC) variables that influence worker safety behavior (WSB) actions on construction sites to improve safety. This research investigates the influence of SC factors on PCS and PCS on WSB in construction site safety. A quantitative research method has been adopted in this study, and the data is collected from the construction professionals working in South India. Statistical analyses were performed for the collected data; consisted of stepwise regression analysis and structural equation modelling (SEM) analysis to determine the significance of PCS. The findings disclose that in direct effect, four out of six SC factors contribute to enhancing PCS, namely supervisor safety behavior, co-worker safety behavior, worker involvement, and safety system, and it shows that PCS influences WSB. In indirect effect of SC factor on WSB two factors positively influence namely: supervisor safety behavior, co-worker safety behavior and remaining two negatively influences. The outcome of this study helps the construction professionals to improve safety performance by fulfilling their obligations and improving WSB in construction sites.

Published: December 2022

Abstract
Several countries have started to more purposefully apply advanced offsite delivery approaches to meet specific housing shortages. The United Kingdom (UK) is no exception. Whilst the concepts and benefits of Modern Methods of Construction are ‘typically’ well understood, it is generally accepted that there is a paucity of knowledge on the actual understanding of optimization per se, ergo, the interrelationships between processes, and the wider understanding of ‘pooling’ [resource management] to promote and maximize synergy - especially to target areas of lag or bottlenecks. In this respect, the research methodological approach adopted in this paper used a single case study to critically evaluate an offsite steel-frame solution for the offsite market to deliver social housing. This approach also evaluated the potential of Generative Design, Discrete Event Simulation, and Digital Twins. Findings of this ongoing research include new opportunities and strategies for these technology-driven solutions, culminating in the development of a new conceptual offsite hub-and-spoke model. These are presented for discussion. This model allows decision-makers to interact with data in order to optimise solutions in line with demand and resource requirements.
Stakeholder engagement and collaboration in overcoming the constraints to delivering low carbon buildings in high-rise high-density cities
Authors: Madhusanka H W N , Pan W , Kumaraswamy M M 
Published: December 2022

Abstract
The building stock in high-rise high-density cities is a principal contributor to global anthropogenic carbon emissions. Even though there are many commitments and action plans, an effective uptake in the delivery of low carbon buildings (LCBs) is not evident in high-rise high-density contexts due to several prevailing constraints. Despite many studies in the arena of LCBs, only a few have focused on analysing stakeholder ‘engagement’ and ‘collaboration’ towards identifying and addressing constraints to delivering LCBs. This paper addresses this gap by employing a Social Network Analysis (SNA) based methodology to explore the required engagement and collaboration of stakeholders in addressing constraints to delivering LCBs in high-rise high-density cities. In total 21 constraints to delivering LCBs were identified through a systematic literature review followed by a questionnaire survey covering Hong Kong, Singapore, Australia (Sydney and Melbourne), UAE (Dubai and Abu Dhabi) and Qatar. Furthermore, 15 influential stakeholder categories were identified from the literature. Subsequently, a two-round Delphi survey was conducted to map the engagement of stakeholders over the constraints and to develop the input dataset for SNA. The SNA results revealed the stakeholders’ influencing ability over each of the identified constraints and their significance in terms of their position in the developed social network structures. The findings should benefit industry practitioners by providing useful insights into potential engagement and collaboration channels for smoothly addressing the constraints to delivering LCBs.
Human Rights, Disability, and Construction: How responsive are building regulations to changing community attitudes towards housing for people with a disability?
Authors: Martel A , Paton-Cole V 
Published: December 2022

Abstract
Responsibility for housing people with a disability has rested with government and the charity-medical model of disability encouraged institutionalized accommodation. However, since the mid-2000s, the introduction of a person-centred approach has seen government’s legislate programs that facilitate people with disabilities living in the community. This shifted supply of appropriate housing to the private-sector and placed a focus on whether current building regulations are capable of regulating in this space. This paper explores the history of building regulations in Australia, in parallel with the history of treatment of people with a disability. The normalization of institutionalizing people with a disability was reflected in early building codes in Australia, continuing from the 1840s until the 1980s when disability theory began to change – but not building practice in Australia. The decisive break between the approach to disability accommodation (person-centred) and the institutional model in building regulations occurred with the move to the National Construction Code (NCC) in the 1990s. The introduction of the National Disability Insurance Scheme (NDIS) in 2014 highlighted the disconnect when a market-based housing model was proposed that proved difficult to implement with current NCC settings. This study highlighted the complex interaction between existing policy settings and identified the scope for individual interpretation of the code around key concepts. These include building classification, single-occupancy units, and fire safety. As a consequence of the institutional model for disability accommodation enshrined in the NCC, the NDIS is undermined in accommodating people in the community, due to uncertainty and confusion within the private-sector industry that has impacted the cost and quality of the housing produced.
The institutional framework of construction safety management: A case study of Sri Lanka
Authors: Melagoda D G , Rowlinson Steve 
Published: December 2022

Abstract
The Sri Lankan construction sector continued to boom in the last decade reporting a 6.78 per cent growth in GDP in 2019. Nonetheless, construction accident statistics recorded 40 fatal and 59 non-fatal accidents in 2019. There is a serious lack of safety management in construction companies in Sri Lanka. The reason is largely attributable to the lack of an institutional mechanism to ensure accountability, planning, prioritising, reviewing, learning, and training for continuous improvement of safety. Therefore, it is necessary to explore the system of laws, regulations, and procedures, and stakeholders with their roles and norms that shape construction safety. The study explored how national level and industry level institutions are linked to construction safety management systems in Sri Lanka through document review and interviews with personnel from the Department of Labour, Construction Industry Development Authority, construction companies, professional bodies, and academic institutes. The Factories Ordinance, No. 45 of 1942 is the main legislation applied to construction safety enacted in the colonial period, thus, no improvements are made to industry -specific requirements and technological advancements. Neither, the Construction Industry Development Authority has any standards, guidelines, or codes of practices to conform to safety. Major construction companies align with international standards (ISO 9000, 14000; OHSAS 18000) to win major construction projects. It indirectly affects maintaining a safe work environment. Therefore, Sri Lanka needs to focus on an industry-level institutional mechanism to improve the safety management system. Further, support from educational and training institutes, trade associations, and professional bodies is necessary to push forward the importance of safety.
Regeneration Design Study Based on Long-lasting Building Strategy of Typical Chinese Work-live Unit in Guangzhou, China

Published: December 2022

Abstract
After rapid urbanization from last several decades, Pearl River Delta area (PRD) in China gradually steps into an urban regeneration process, especially in the field of housing sector. However, neighbour and housing reform activities in last few years focused on the inner prat of the cities where are mainly historical districts or chaotic urban villages. While another large proportion of housing in “Dan Wei” has been ignored. It is a typical Chinese working unit combined with living and other activities, but currently faces new challenges of social and functional transformation. Although a new regeneration design strategy: “Micro-upgrading”, was firstly proposed in Guangzhou and specific for this neighborhood typology, it still cannot ideally resolve its core negative issues in last few years. Therefore, based on an architectural school’s design course, this study will select a region concentrated of “Dan Wei” units in Guangzhou, which is the core city of PRD. By making use of “Open Building” theory and “Level” strategy, some valuable research outcomes and design solutions will be discussed and proposed.

Published: December 2022

Abstract
The studies show that risks occur during the construction of projects and affect performance in terms of cost, time, and quality. However, with the growing evidence of cost and time overruns associated with public tertiary education building projects, this paper assessed factors predisposing these building projects to risks. Using the survey method, four hundred fifty-two questionnaires were administered to consultants, contractors, and client representatives across five tertiary education institutions. The research instrument’s reliability value was 0.763 via the Cronbach alpha test. Therefore, of 452 questionnaires administered to the respondents, 279 were retrieved, representing 61.73% return rate, and analysed. Furthermore, the top three factors include financial constraints, location of the project, and project type. In contrast, economic requirements, special and legal conditions, and building use are the minor predisposing factors. The respondents had convergent views on eight out of eleven factors except for project duration, economic requirements, and building use. Besides, the eleven factors presented in the study were significant and recorded high mean scores, implying suitable parameters for measuring factors predisposing public tertiary education building projects to risks. Based on the preceding, the study provided information on the factors that could enhance the performance of public tertiary education building projects.
Crisis Driven Literature in PPPs: A Network Analysis
Authors: Castelblanco Gabriel , Guevara Jose 
Published: December 2022

Abstract
COVID-19 crisis has simultaneously triggered a global economic crisis whose consequences will lead to a dichotomy where several governments’ debt has grown to unprecedented levels and simultaneously is required to promote new infrastructure supply. This global economic crisis scenario endangers current Public-Private Partnership (PPP) programs given their dependence on payment from the user and/or government subsidies in long-term lifecycles. This study aims for unravelling the PPP research agenda derived from the last global economic crisis in 2008 and the current one for understanding the trends developed as a tool for building a post-pandemic PPP research agenda. For understanding the last global financial crisis PPP literature review and its time and geographic evolution since 2008, this study developed a literature review employing Network Analysis. Therefore, crisis- and PPP-related keywords were combined for establishing the search in the Web of Science database. After removing duplicate papers, 67 peer-reviewed articles were identified for recognizing underpinning topics, potential gaps, and time evolution. The network analysis revealed seven clusters driven by payment sources (i.e., public financial aspects, user payments, and demand), contract mechanisms (i.e., contractual governance, and risk valuation), and project performance (i.e., project performance under crisis and project efficiency). This paper contributes to the PPP body of knowledge by unraveling the post-global economic crisis agenda and its gaps in proposing a new research agenda for overcoming the consequences of the global economic crisis derived from the COVD-19 pandemic.
