Abstract
Purpose
This work affords a practical checklist that specifies the civil engineering trades-related hazards and offers a safety indicator to identify the safety level of a construction project concerning the hazards of the civil engineering trades.
Design/methodology/approach
The methodology depends on reviewing the archival works, visiting the construction sites, utilizing the direct observation and preliminary hazard analysis methods and conducting semistructured interviews to pinpoint and validate the checklist of the civil engineering trades-related hazards. Additionally, a questionnaire-based survey with the rank sum weight technique has been employed to assemble and analyze the data required to build the safety indicator.
Findings
Relying upon the used methodology, 70 hazards under the trades of general environment, earth, demolition, excavation, concrete, dewatering, waterproofing insulation and scaffolding have been pinpointed and validated. This is in addition to the safety level indicator of the civil engineering trades-related hazards (SLICETH), which indicates high viability during its validation in five national and international projects.
Originality/value
The value of this work lies in its ability to tackle the gap existing in the safety management knowledge regarding the notion of the hazards of the civil engineering trades and their influences on the safety performance of the construction projects. As a result, it offers a complete knowledge to the academics and the practitioners for confronting the negative impacts of the civil engineering trades-related hazards. Consequently, it helps in enhancing the safety performance level in the sites of the construction projects.

Abstract
This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

Abstract
Purpose
The purpose of this paper is to determine the unproductive time and additional cost to re-engineer a safety control system for a Floating Production Storage Offloading vessel that was originally engineered and documented in computer-aided design (CAD).
Design/methodology/approach
The “As-Built” drawings contained numerous errors and omissions, which resulted in a “requests for information” being raised and productivity rates reduced – these costs and productivity losses are quantified. The use of CAD to originally engineer and document the safety control system was found to be inefficient as a 1:n relationship existed. Systems Information Models (SIMs) presents an alternative method to produce engineering documentation for the safety control system; where a 1:1 relationship is created between the model and the real objects. By constructing a 1:1 model, information redundancy can be eliminated, which reduces the propensity for errors and omissions to be made by engineers.
Findings
The use of a SIM to re-engineer and document the new safety control system resulted in significant productivity benefits being achieved. Consequently, it is proffered that a paradigm shift from a 1:n to 1:1 perspective is required for engineering electrical and instrumentation systems so as to ameliorate the quality of documentation produced and productivity.
Originality/value
The paper concludes by suggesting that future research is required to examine how processes and procedures can be re-designed to accommodate the use of a SIM.

Abstract
Purpose
Using the large database of patent, the purpose of this paper is to structure a technology convergence network using various patent network analysis for integrating different results according to network characteristics.
Design/methodology/approach
The patent co-class analysis and the patent citation analysis are applied to discover core safety fields and technology, respectively. In specific, three types of network analysis, which are centrality analysis, association rule mining analysis and brokerage network analysis, are applied to measure the individual, synergy and group intensity.
Findings
The core safety fields derived from three types of network analysis used by different nature of data algorithms are compared with each other to understand distinctive meaning of cores of patent class such as medical safety, working safety and vehicle safety, differentiating network structure. Also, to be specific, the authors find the detailed technology contained in the core patent class using patent citation network analysis.
Practical implications
The results provide meaningful implications to various stakeholders in organization: safety management, safety engineering and safety policy. The multiple patent network enables safety manager to identify core safety convergence fields and safety engineers to develop new safety technology. Also, in the view of technology convergence, the strategy of safety policy can be expanded to collaboration and open innovation.
Originality/value
This is the initial study on applying various network analysis algorithms based on patent data (class and citation) for safety management. Through comparison among network analysis techniques, the different results are identified and the collective decision making on finding core of safety technology convergence is supported. The decision maker can obtain the various perspectives of tracing technology convergence.

Abstract
Purpose
The purpose of this paper is to identify the factor structure of safety culture construct among engineering students at university context and to examine the measurement invariance of this instrument across different socio-demographic groups in a sample of engineering students in the United Arab Emirates (UAE).
Design/methodology/approach
An exploratory online questionnaire was completed by 770 undergraduate and postgraduate engineering students across the UAE. Data were analyzed using a diversified multi-group and a robust and sophisticated cross-validation testing strategy. Confirmatory factor analysis (CFA) was used to test factor structures identified in previous studies. Multi-group invariance testing was conducted to determine the extent to which factor structure is comparable across groups (i.e. gender, educational and experiential background).
Findings
Three-factor model was preferred for its parsimony. The results showed that the level of safety awareness and attitude is relatively satisfactory, whereas safety behaviour is inadequate. No significant difference was showed in multi-group invariance between demographic groups.
Research limitations/implications
This research is a cross-sectional study and limited to the views of engineering students (informal group). The study would benefit from both informal and formal groups in assessing safety culture at university for a robust empirical evidence. The research highlights relevant implications for policy and program development, by pointing to the need to promote safety culture and mitigate safety-related accidents among engineering students.
Originality/value
This paper offers insight into benefit of understanding the level of safety culture among engineering students and extend knowledge of informal group involvement in safety-related accidents at university level.

Abstract
The construction industry has a poor safety record. There is a common perception that this is because it is an inherently dangerous industry. It is suggested that the industry would be better characterized as one with a poor safety culture and that attempts to improve the safety record will not be fully effective until the safety culture is improved. The relationship between unsafe behaviour and safety culture is discussed together with the difficulties of assessing and managing safety culture. Some of the influences on safety culture in construction are described. The initiative to develop an improvement in the safety culture of construction needs to come from within the industry through a genuine commitment to safety.

Abstract
Purpose
This study has a scope limited to a specific course and changes integrated to the core of the KTH naval architecture master program. The students in the program have earlier experience from engineering applications in a general sustainability perspective and understand the basic concepts within sustainability. Therefore, to introduce further steps a new course module was introduced in 2018 focusing on safety management and social sustainability. The purpose of this study is to identify and document the pedagogic lessons for a course module where sustainable development (SD) is discipline-specific.
Design/methodology/approach
This study is a case study that qualitatively investigates the stainability effects of the implementation of the new course module. The course and program activities are compared to the results of a previous study in 2017 on the sustainable development learning elements (SDLEs) in the program and discussed in relation to more general SD initiatives.
Findings
From the analysis, it is identified that the perspectives presented were new to a substantial part of the students. This study also shows that the effects of the specific module here studied, with a focus on the skill of maritime social sustainability development, differ from more general sustainability literacy. The new perspective affected the thinking about the core of the students’ studies, ship design, in a way that general knowledge on sustainability has not. This was achieved with a combination of suitable tools and perspectives in combination with contextual knowledge and a frame of reference. The contextual knowledge and a frame of reference are here present in education as a result of relating the sustainability case to the core of the program.
Originality/value
The result relates the pedagogical change described to SDLEs and to the ambition of conceive, design, implement and operate approaches. This paper contributes to the literature by providing a discussion on how social sustainability can be implemented in engineering education and the role of integrated discipline-specific sustainability modules.

Abstract
Purpose
This paper aims at developing a methodology capable of controlling accidents and failures in oil and gas production activities.
Design/methodology/approach
Fuzzy analysis that is based on fuzzy linguistics, rule matrix, rule structures, and system operating rules is utilised. Fuzzy methodology is applied to develop a safety control model for the prevention of accidents and failures in oil and gas production activity offshore platforms.
Findings
The model is demonstrated with a case study, thereby suggesting the feasibility of the applied approach in practical cases.
Practical implications
Primarily, the study aims to guarantee safety. Also uncertainties and imprecision that commonly characterize safety measurement systems are tracked. The time‐consuming activity in measurement and the requirement of lots of specific information about the process is avoided.
Originality/value
The results from the study provide valuable baseline information for future research investigating how safety of oil platforms is affected by some factors.
