In order to improve the overall safety performance of firms, it is critical to evaluate and eliminate the root causes of such incidents. This study aims to identify and assess the systemic lapses as the main causes of accidents in the construction industry. The study introduces a framework of Policy, Process, People, and Incentive factors, coupled with the Systems Theoretic Accident Model and Processes (STAMP) model to demonstrate a more comprehensive understanding of the contributing factors that escalate to construction accidents. A survey questionnaire with 31 respondent firms was conducted regarding the perceived importance of, and level of adoption of, factors that were associated with the framework. The findings revealed that, with regards to the safety-related practices, there is an overall lower adoption rate in comparison to their perceived level of importance. In particular, people and incentive factors are highlighted as having a significant difference in terms of the extent of adoption and level of importance. However, the people and incentive factors should not be isolated from the policy and process factors, as a comprehensive approach is needed to improve the overall safety performance of firms.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"105 1","pages":"81 - 98"},"PeriodicalIF":1.8,"publicationDate":"2018-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85881283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural nonlinearity is presented into the structure, as materially nonlinear, by calibrating plastic hinge at the end of the elastic beam-element of the structure. To guarantee ideal circumstance for seismic analysis, this study includes inelastic soil stratum by using an equivalent linear approach. Monte Carlo simulation is performed by means of seismic vulnerability of the structural system. The research presents a study of a large amount of simulation over the nonlinear and linear structures considering the random character of basic variables of soil under selective earthquakes. The earthquakes having different source-to-site (STS) distances ranging from 7 to 145 km have consistency with the soil parameters. This rigorous implementation is done to accomplish site-specific dynamic analysis. Illustrative results obtained from nonlinear and linear dynamic analysis are compared. The overall finding shows that the nonlinear structure produces highest estimated uncertainty compared to the linear structure. Another termination can be addressed that the earthquake with less STS distance (7.29 km) causes the highest level of destruction to the structure.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"125 1","pages":"221 - 237"},"PeriodicalIF":1.8,"publicationDate":"2017-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86423656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the contributions of built environment design elements to environmental sustainability were evaluated through a questionnaire survey with the participation of 323 people who previously worked in urban renewal projects. Implementing factor analysis, interrelated elements have been gathered under five factors: ‘transportation and accessibility’, ‘conservation of natural resources’, ‘built environment quality’, ‘supporting social life’ and ‘high-density usage’. To identify the importance weights of these factors, analytic hierarchy process (AHP) analysis was carried out with 40 academics and practitioners. Based on the results, ‘conservation of natural resources’ was found as the most important factor affecting the environmental sustainability of urban renewal projects. It is expected that the results of this study shall guide a wide range of urban renewal stakeholders, extending from designers to citizens, along the path of creating environmentally sustainable cities.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"73 1","pages":"264 - 277"},"PeriodicalIF":1.8,"publicationDate":"2017-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74643467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A methodology is proposed to evolve Pareto optimal management strategies for a multi-layered coastal aquifer system using a trained and tested Multivariate Adaptive Regression Spline (MARS) surrogate model linked to a multi-objective saltwater intrusion management model. Performance of the developed methodology is evaluated using an illustrative multi-layered coastal aquifer system. Solution results indicate that MARS is capable of approximately replacing the more rigorous numerical simulation model within the linked S–O model to ensure computational efficiency and feasibility in applying such linked S–O models for coastal aquifer management problems. Furthermore, the ability of MARS to recognise the most relevant input variables in predicting the responses as outputs enables the construction of an efficient and robust surrogate model. Integration of parallel processing capabilities within the optimisation model is shown to improve computational efficiency and feasibly of solving such large scale multi-objective problems. Therefore, the developed methodology utilising the MARS based surrogate model is potentially applicable for developing optimal groundwater extraction strategies for sustainable regional scale management of coastal aquifers.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"20 1","pages":"238 - 263"},"PeriodicalIF":1.8,"publicationDate":"2017-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91274782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poor investment choices risk locking in poor policy choices for substantial periods of time. The ‘need’ for a new infrastructure asset arises due to demographic, economic or policy changes. But historically Ireland’s infrastructure investment has also been driven, in part, by the pursuit of political / economic policies which have themselves ‘created’ infrastructure needs; and often decided on an isolated project-by-project basis. In contrast, a systems-of-systems (SoS) approach is a fusion of network modelling, consideration of various policy options, and appraisal of the impact of alternative demographic and economic scenarios on multiple systems. This paper assesses Ireland’s readiness to adopt a SoS approach to infrastructure decision-making, proposes a methodology for its development and implementation. This would enable the demand for new infrastructure to be tested under various policy scenarios, providing evidence for investment decisions.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"34 1","pages":"185 - 205"},"PeriodicalIF":1.8,"publicationDate":"2017-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81263486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this study was to analyze the extent of inundated land from sea level rise and its economic impacts to residential property in coastal communities. Geographic data were integrated with economic and social data at parcel level resolution through GIS. Cumulative land inundation in seven coastal municipalities was calculated as 15 and 25 km2, while direct economic costs to residential property was estimated to be $1.3 billion and $2.2 billion for 1 and 2 m sea level rise, respectively. Normalised results were $14 million/km coastline and $4 million/km combined coastline and rivers for 1 m sea level rise. Results indicate that while impacts will mainly occur along the coastline, inland parcels as far as 3 km from the coastline situated along rivers are equally at risk of flooding. While results of the study can be used to estimate economic impacts for other locations that share similar geographic characteristics and development patterns, land use types, proximity to water bodies, and property values are some factors that may lead to differences when these numbers are extrapolated elsewhere.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"12 1","pages":"103 - 89"},"PeriodicalIF":1.8,"publicationDate":"2017-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85276443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern Methods of Construction (MMC) represent a response to the sustainability trend, since they bring faster construction and better environmental, energy and economic parameters. The aim of this article is to analyse and evaluate the benefits of MMC in the form of Prefabricated Panel Wood Construction (PWC). With the aid of a case study, certain environmental and economic parameters of PWC on the one hand and traditional Masonry Construction (MC) from ceramic bricks on the other hand will be studied and compared. The environmental evaluation of building material composition was conducted by means of the ‘Cradle to Gate’ model within the LCA method. The parameters in question will be studied in terms of embodied energy, global warming potential and acidification potential. The economic parameters to be analysed include construction time, construction costs and particularly the environmental burden caused by transport of materials to the building site. The submitted experimental study and its results should help break barriers sustained by traditional technologies and point towards healthier and more environmentally friendly alternatives in construction processes.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"49 1","pages":"127 - 143"},"PeriodicalIF":1.8,"publicationDate":"2017-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75330856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was done using empirical data collected by the author in 2015. In the introduction and theoretical part of this text, the term ‘environmental intelligence’ is defined, and issues raised by modern sociologists such as M. Maffesoli and M. Archer are presented. Two hypotheses stating that respondents from Poland, Slovakia and Czech Republic have higher levels of environmental intelligence than university students from the Ukraine, and those studying natural sciences have higher levels of environmental intelligence than students of the humanities or social sciences were verified. The statistical analysis conducted in the second part of the text revealed a higher level of environmental intelligence among students from the European Union countries compared to respondents from the Ukraine. However, there were no significant differences between the level of environmental intelligence and respondents’ faculty of studies. This indicates that studying natural sciences did not contribute to a more dynamic development of environmental intelligence in students. This revelation may be disturbing, as the state of the environment cannot improve if young people cannot use and care for it responsibly.","PeriodicalId":50689,"journal":{"name":"Civil Engineering and Environmental Systems","volume":"133 1","pages":"104 - 126"},"PeriodicalIF":1.8,"publicationDate":"2017-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86215051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
