Abstract
A major contributory factor to poor project performance in the construction industry is known to be the lack of integration and coordination between the different disciplines involved in various stages of the procurement process. Attempts by researchers to address this problem have met with limited success, as they have focused mainly on adapting integration techniques originally developed for use in the manufacturing industry. There is therefore a need to develop a detailed understanding of the fundamental sciences that underpin the problem of integrating the procurement process across the construction project life cycle. Presents and discusses a research model for addressing major methodological issues in the analysis of design/construction relationships.

Abstract
The cost of concrete ground‐supported floor slabs represents a significant proportion of the total capital cost of industrial projects. There are many structural design issues that impact on the concrete contractors’ method of construction. This is becoming more apparent with the use of new high‐technology levelling and trowelling equipment, which has significantly increased the pour and finishing rates, resulting in much faster slab construction times compared with the traditional methods of construction. Selection of both the design and the construction methods exerts a large influence on the initial cost. According to the results of the research reported in this paper, it may be possible to save between 2‐4 per cent of the building cost if high technology solutions are incorporated into the design and construction process. This paper investigates cost issues that impact on the design and construction of ground‐supported floors for industrial buildings.

Abstract
Purpose
Road accident is a major threat to sustainable road safety, causing immense suffering and posing an increasingly serious global challenge, especially in developing countries. It is the leading cause of death, injuries and property damage. While vehicle driver-related factors play a significant role in accidents, poorly designed and constructed roads are also a growing factor. As result, this study aims to assess traffic accident problems associated with design-construction complications on Arba Minch-Jinka Road, Ethiopia.
Design/methodology/approach
From 2013 to 2021, a large amount of traffic accident data was gathered, and through actual roadway surveys at potential locations along the road, the data was associated with design-construction parameters. The analysis was done by adopting descriptive statistics incorporating comparative hypotheses, in which the individual and combined effects of design-construction issues were identified. Results revealed, on average, 76% of total coincided accidents along the study road were associated with design-construction issues. Exclusively, causing factors, i.e. roadway, driver, vehicle, pedestrian problems and environmental, contributed 7.65%, 77.78%, 6.17%, 6.05% and 2.35% traffic accidents, respectively.
Findings
Detailed and time-consuming data collection, investigations, analysis and assessments were used in the research to discover a strong association between road design-construction problems and traffic accidents. As a result, 42 black spot sections were identified, and 7.65% is exclusively caused from design-construction problems. Curved road sections led the surge by 42% from selected design-construction variable, whereas the remaining 58% was shared among four parameters. According to relative analysis, design-construction issues caused a 58.17%, 12.14%, 32.36% and 29.93% increase in accidents in combination with driver, vehicle, pedestrian and environmental factors, respectively. This is in an average of 33.15% escalated problem in a combination that raises questions about the sustainability of road safety.
Originality/value
It is essential to use scientific methodologies to evaluate traffic accidents and associated design-build discrepancies in developing nations like Ethiopia if we are to achieve sustainable road safety. The fundamental importance and value of this study is that it promotes accountability to the road design and construction, which are not frequently thought of as influencing factors in traffic accidents. This paper is original, and all references have been correctly mentioned, to the best of the author’s knowledge.

Abstract
The equability of environment, social and economic elements becomes a major issue to be achieved as to attain sustainability in the development of a construction project. As to cater to social sustainability, the Guidelines on Occupational Safety and Health in Construction Industry (Management) also known as OSHCIM has been introduced by the government to improve safety practices amongst Malaysia’s construction practitioners. The basic principle adopted in OSHCIM is Prevention through Design (PtD), which enhances the elimination of hazards during project design stages. This concept is inspired from the implementation of Construction (Design and Management) (CDM) Regulations in the United Kingdom. The concept has also been adopted and practised in many developed countries including Australia and Singapore. The aim of this study is to identify the dominant accident causes in Malaysian construction industry. In this study, the secondary data were gathered from the Department of Occupational Safety and Health (DOSH) accident statistics. A content analysis and frequency distribution analysis were adopted to determine causal factors that contribute to the fatality. The findings show the existence of design-related causal factors, which is also incorporated with other causes of accidents. This is true as every accident occurs due to more than one factor. Thus, these inputs will recommend further exploration to determine the design-related causal factors. This may help the industrial players, including stakeholders, practitioners and researchers, to have more focussed efforts and resources in ensuring the success of OSHCIM’s implementation to reduce the accident statistics in Malaysia.

Abstract
Purpose
To further promote application of BIM technology in construction of prefabricated buildings, influencing factors and evolution laws of willingness to apply BIM technology are explored from the perspective of willingness of participants.
Design/methodology/approach
In this paper, a tripartite game model involving the design firm, component manufacturer and construction firm is constructed and a system dynamics method is used to explore the influencing factors and game evolution path of three parties' application of BIM technology, from three perspectives, cost, benefit and risk.
Findings
The government should formulate measures for promoting the application of BIM according to different BIM application willingness of the parties. When pursuing deeper BIM application, the design firm should pay attention to reducing the speculative benefits of the component manufacturer and the construction firm. The design firm and the component manufacturer should pay attention to balancing the cost and benefit of the design firm while enhancing collaborative efforts. When the component manufacturer and the construction firm cooperate closely, it is necessary to pay attention to balanced distribution of interests of both parties and lower the risk of BIM application.
Originality/value
This study fills a research gap by comprehensively investigating the influencing factors and game evolution paths of willingness of the three parties to apply BIM technology to prefabricated buildings. The research helps to effectively improve the building quality and construction efficiency, and is expected to contribute to the sustainability of built environment in the context of circular economy in China.

Abstract
Purpose
The design documents are products of a process that aims to provide sufficient details to enable the contractor to efficiently implement the project at a realistic cost. Accordingly, it is expected that these design documents must be of high quality to engender the attainment of the desired project objectives. The purpose of this study is to analyze the factors that affect the quality of design documentation in construction projects in the context of a developing country.
Design/methodology/approach
This study used a descriptive research design involving professionals from firms offering services in areas of design and documentation, mainly architectural, quantity surveying and engineering. A total of 80 out of 84 questionnaires were received and analyzed using IBM SPSS Statistics Version 25, and a factor analysis approach was used to categorize the factors into smaller five groups.
Findings
The factors were subsequently categorized according to size, time, staff, quality and training-related factors. Collectively, large size of the project, inadequate supervision of junior design staff, low professional fees, procurement process and system, failure to adopt quality management systems and allocation or assigning of staff to more than one project at the same time have high influence (component loading of 700) in respective groups.
Research limitations/implications
The reliance on data to analyze the factors of design documents in construction projects in developing economies context, using a Tanzanian exemplar, is considered a limitation. Developing countries with similar economic characteristics, procurement systems and cultural setup could benefit from the results of this study.
Practical implications
The study of factors affecting quality of design and documents in construction projects serves as a guide for built environment firms in Tanzania in conducting effective business and ensuring quality design documents, hence improved project performance. Understanding the nature of relationship between the design and construction teams as well as the impact of design documents on project performance is of great importance for the design teams of future projects and other decision-makers to pay attention when preparing design and related documents, especially during design stage of construction projects in developing countries.
Originality/value
The study contributes the knowledge by providing useful insights on the subject through a categorization of the factors affecting the quality of design documentation and exploring the nature of relationship between the design and construction teams in construction projects within a previously unexplored Tanzanian context focusing on a traditional procurement system for future improvement of project delivery, hence project success.

Abstract
Purpose
This paper aims to inquire into the awareness of Vietnamese architects about design for safety (DfS) and the level of engagement in applying DfS among them to get a generic view of the implementation of DfS in Vietnam.
Design/methodology/approach
Quantitative research was used, in which a questionnaire was sent to Vietnamese architects to evaluate how they consider and apply DfS in the design process. Inferential and descriptive statistics then analysed the obtained data to identify the role of each factor.
Findings
The results from the survey conclude that Vietnamese architects have low engagement in applying DfS despite their high awareness and positive attitude towards DfS. Besides, the participants showed the need for further DfS education and training, which is lacking in Vietnamese formal education. In addition, the research also confirms that DfS education and training have positive impacts on the frequency of DfS implementation in Vietnam.
Research limitations/implications
This research contributes to the knowledge of DfS implementation in developing countries. In line with this, further studies on the DfS concept in developing countries are needed to draw a more objective overview and give the solution for the low DfS appliance.
Originality/value
To the best of the authors’ knowledge, this is the first study inquiring into the implication of DfS in Vietnam, contributing to improving the lack of knowledge in this field in developing countries and Vietnam in particular.

Abstract
Purpose
This research aims to examine the practice of design for safety (DfS) in the construction industry of Saudi Arabia.
Design/methodology/approach
The study has adopted a mixed-method approach through the use of questionnaire surveys administered to professionals in architecture and engineering firms, as well as follow-up interviews with selected participants. The participants consisted of architects, structural engineers and electromechanical engineers. The study investigated dimensions related to knowledge and awareness, attitude toward DfS implementation and critical success factors for DfS implementation. These various dimensions have been assessed accordingly through the mean ratings in the relevant section of this paper. The thematic responses obtained from the follow-up interviews have been summarized and presented.
Findings
The findings from this study reveal a high level of awareness of DfS in Saudi Arabia. It also revealed that the most influential critical success factors are legislation and awareness of stakeholders, whereas the major barrier is the fear of cost overruns by the clients and their representatives.
Originality/value
The design stage of construction projects is crucial to enhancing the safety performance of projects through effective control of hazardous situations. The concept of DfS is, however, immature in many countries, such as Saudi Arabia, due to lack of awareness, enabling policies and other barriers. The value of this study is that it shows the current level of knowledge and practice of DfS in architecture and engineering firms in Saudi Arabia and consequently triggers the interest of stakeholders in its adoption and implementation.
