This study proposes a novel approach based on a neural network fitted with the Levenberg-Marquardt algorithm to predict future accident numbers in 22 different occupational groups within the Turkish construction industry. By utilizing historical official data spanning the years 2014 to 2022, the aim is to provide insights into the potential accident rates that may arise in different job categories. The constructed neural network model consists of two hidden layers. Leveraging the powerful capabilities of the Levenberg-Marquardt algorithm, the network is trained to effectively capture the complex dynamics underlying work accidents in the construction industry. The findings demonstrate the effectiveness of the proposed approach in forecasting future accident numbers with a high degree of precision. The neural network model successfully leverages the temporal trends and underlying factors present in the historical data. By employing an advanced neural network framework and the Levenberg-Marquardt algorithm, this study offers a robust methodology for predicting work accident rates across diverse job categories. The results obtained from this study can guide the development of targeted preventive measures, tailored training programs, and efficient resource allocation strategies.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":"134 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141810935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating safety considerations into the design process, it becomes possible to eliminate or minimize risks before they become costly and dangerous issues can also be avoided during construction. To gain insights into the current practices and barriers faced by professionals in the construction industry of Pakistan regarding DfCS, a comprehensive study was conducted. This study utilized a combination of questionnaire-based surveys and interviews to gather data from various stakeholders involved in the design and construction processes. The research revealed that DfCS was absent in the standard design practice. The weaknesses identified for the implementation of DfCS were designers’ inevitable doubts about increasing cost, schedule problems, absence of contracts and regulations, designers’ lack of safety knowledge and skills. The largest influential factors were regulatory liability on the designer (29%) and increasing costs (27%). The study identified that less trained worker were rated 59% for site accidents. 87% of respondents suggested revision of contract and regulations. The study proposed a framework to check constructability with respect to safety standards. Alternative project delivery method i.e., Design Build (DB) was recommended to reduce health and safety accidents and barriers.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":"13 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141813624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although SOR systems have been widely adopted by many large engineering contractors, the further benefits gained from their utilisation are unclear. Existing systems have an ’after the fact’ nature and a lack of clarity exists surrounding how information derived from the system can proactively contribute to safety interventions. The research design employed a case study as the foundation, examining the use of an SOR system within a leading infrastructure contractor. Subsequently, semi-structured interviews were conducted with six participants from the case study company, with thematic analysis used to develop findings. Initial suggestions for guidance were produced before these were presented for validation by two representatives from the initial six participants, and a further three respondents from two different contracting companies. The feedback and suggestions from these refined and increased the applicability of the resulting recommendations, which aim to give consistent categorisation, greater access to information developed, and the facilitation of improved communication of learnings. This research contributes insights into the complexities of SOR systems and offers practical guidance for their enhancement.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":"35 42","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141340336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scheepbouwer, Philip J Barutha","doi":"10.1680/jmapl.23.00012","DOIUrl":"https://doi.org/10.1680/jmapl.23.00012","url":null,"abstract":"The use of Pre-Construction Services (PCS), also known as Early Contractor Involvement (ECI) in construction projects has become common internationally due to the various advantages it offers in complex projects. What remains an open question to researchers and government organisations is defining the optimal time to engage in it. This paper develops a methodology that reports on the successful timing of PCS use in New Zealand. This methodology and findings can assist the industry in determining when to appropriately engage a contractor for PCS in New Zealand. Reporting on the successful timing of PCS can help the industry avoid costly pitfalls when engaging in PCS too early or too late. This approach could be extended to an international audience. The timing of PCS and project complexity are closely related. For this paper data was collected in two rounds. Firstly, an online survey was used to determine weights for complexity factors, then a visualization tool was developed and refined using 29 case study projects derived from semi-structured interviews. The results show that there is a relationship between the timing of PCS, the project complexity, and the scale of a project. Additionally, findings show that PCS is not always related to the procurement method. For example, Design-Bid-Build (DBB) projects can still receive valuable PCS to make them successful through fair risk allocation. PCS can have an impact on the contract terms. Each project was given a complexity ranking based on the information given by the interviewees during semi-structured interviews. While the semi-structured interviews were extensive, the information is only as accurate as the recollection of the participant. This risk was minimised by the prequalification of the participants. The findings of this research will assist clients in determining when the best time is to engage PCS. Independent of the procurement model, and will assist clients in maximising the value that the contractor can bring to construction projects.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":" 54","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141000314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Virtual safety training methods often fall short in terms of realism. This article introduces a pioneering approach that exploits digital twins to create Virtual Training Environments (VTEs) tailored for construction safety. The Digital Twin for Construction Safety (DTCS) framework seamlessly integrates Building Information Modelling (BIM) models, schedules, resources, and hazard data into a prototype using the game engine Unity. It enables the generation of VTEs with minimal user interaction, empowering safety trainers to define personalised scenarios based on specific project parameters and training requirements tailored to the trainees’ needs. The evaluation of this approach through three distinct real-world projects and a case study with six trainees demonstrates its efficacy. Results indicate the DTCS framework’s ability to efficiently create VTEs independently of the project once a BIM model is available. Moreover, the framework provides meaningful feedback to the trainee by evaluating the performance using run-time data collection. The collected data promises use for several applications, but future research must validate its effectiveness. Beyond training, the study highlights the utility of VTEs in improving safety design and hazard mitigation strategies through data-driven insights.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":" 48","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140999244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Information gleaned from literature shows that the ageing workforce and inability to attract young people are reasons for labour shortages in the engineering sector. To address this shortage, several countries have created various programs, such as degree apprenticeship, to ease the process of recruiting, training and retaining young people. The current study seeks to: (i) uncover factors influencing the decision to sign-up for degree apprenticeship programs and (ii) unearth the factors affecting the outcome of degree apprenticeship programmes in engineering. Interviews were conducted to address the research objectives of the study. The findings indicated that awareness, covid-19 pandemic, funding, incentives [financial and non-financial] and diversity are key factors influencing the decision to sign-up for degree apprenticeship. Also, demand for engineering jobs, balance between theory and practical training, collaboration of stakeholders, leadership support, versatility of apprentice experience are the factors affecting the outcome of degree apprentices. Based on the findings, it is evident that raising awareness among stakeholders, such as career counsellors, and collaboration are vital for improving the supply of qualified young people in the engineering sector.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":" 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140998519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whilst the use of Virtual Reality (VR) has gained increased global attention in the past decade, the documentation of practical applications during active construction projects in the UK remains underdeveloped. Specifically, this includes the use of VR within on-site construction logistics management processes, and its potential impacts on multidisciplinary collaboration and engagement. This study aims to bridge this gap by exploring the use of VR during practical safety and plant logistics planning workshops to capture real-world examples. Collaborating with a UK based construction contractor, this study collected qualitative data over a series of planning workshops during a live project, involving 15 site team members of varying disciplines. Data collection included direct observations and focus groups, with data analysed using a hybrid thematic analysis method. The results provided evidence of effective and accurate plant logistics planning with working practical examples, indicating that the use of VR had a positive impact on interdisciplinary collaboration and engagement. Results show that the inclusion of VR tools also encouraged knowledge transfer between project teams, which led to improved confidence and engagement when conducting planning activities.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":"34 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140655938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study adopted an exploratory sequential mixed design method with an initial qualitative data collection phase followed by a quantitative data collection phase. Responses from the qualitative phase (via interviews) were thematically analysed, while data obtained from the quantitative phase were analysed by means scores and standard deviations, the Normalized Value test, and the Mann-Whitney U test. The study identified ten attributes of designers’ competencies for DfD implementation. The four key competencies were identified as, in order of importance: proper expertise and motivation; designers’ knowledge of material quality and durability; strong understanding of construction; and effective coordination of element and component dimensions. The results of this study shed light on a less explored aspect of competencies for DfD implementation in the construction sector, especially in the global south. It provides fresh data and new insights into the attributes of designers’ competencies for DfD implementation.","PeriodicalId":517247,"journal":{"name":"Proceedings of the Institution of Civil Engineers - Management, Procurement and Law","volume":"15 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140441161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
