The study aimed to reduce the density of structural elements while maintaining their original purpose by filling the interior of the members with interconnected strut members to replicate the structure of animal bones. The strut members were created using the edges of Voronoi cells, and stress was used as an additional variable during the Voronoi iteration to prevent stress concentration on the strut members. The proposed approach resulted in a more uniform stress distribution in the strut member than when Lloyd's algorithm was used. However, perfect uniformity was not achieved due to certain factors, and several issues were identified during the 3D printing process. These findings will refine the proposed algorithm to achieve perfect uniformity of stress distribution in the following steps. The approach presented in this study offers unprecedented opportunities for modern engineering to create structural members that are equally resistant to internal stresses as observed in animal bones. ©","PeriodicalId":177185,"journal":{"name":"Proceedings of the Creative Construction Conference 2023","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116454661","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}

A well-trained craft workforce is crucial to maximizing the worker’s potential and productivity. Studies in the existing literature have highlighted the importance of workforce training and its role in mitigating the impact of widespread workforce challenges and tight labor markets. Despite that, no research has yet quantified how training impacts workers’ performance. The objective of this paper is to analyze and understand the impact of workforce training on the self-evaluated performance record (including safety, attendance, quality, productivity, and initiative) of construction workers and frontline supervisors in the construction industry. To achieve the research objective, 2468 construction craft workers and frontline supervisors were surveyed using an online questionnaire. The survey participants were asked to self-evaluate their work personal performance record. The participants were additionally asked to specify how many hours of training they have completed in recent years including craft skills, job management skills, and planning skills. The collected data was then analyzed. Key findings indicate workforce training had a statistically significant impact on increased worker performance.","PeriodicalId":177185,"journal":{"name":"Proceedings of the Creative Construction Conference 2023","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127066368","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}

Cabello","doi":"10.3311/ccc2023-075","DOIUrl":"https://doi.org/10.3311/ccc2023-075","url":null,"abstract":"Falls from height are a relevant occupational health and safety problem, given the significant impact they have on an injured worker, as well as on their families and the company to which they belong. Although most countries are trying to reduce the number of accidents due to this cause, the injuries resulting from these accidents are usually severe. The causes of falls from height are varied, including lack of control by the direct supervisor, irresponsibility of the worker or wrong handling. Also, they can be caused by auxiliary elements (platforms, ladders, machinery or others) required for the execution of a task, which needs to be assembled appropriately or safely. This article provides the context of using auxiliary equipment (fixed and mobile scaffolding and safety rail) for work at height. Then, a field information survey is carried out to describe the main problems regarding their use on-site. Finally, through the application of 44 semi-structured interviews with construction professionals and supplier companies in the Chilean market, different appraisals on the safety of working at heights and the use of auxiliary equipment are described. The results show that the relevant aspects in the use of auxiliary elements to prevent the risk of falls are related to the singularity of the projects under construction, the scarcity of regulations or their updates, in addition to the lack of technical information on-site that would allow the constant verification of auxiliary equipment, among others.","PeriodicalId":177185,"journal":{"name":"Proceedings of the Creative Construction Conference 2023","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129280207","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}
