Develop a project schedule that allows for systems testing and commissioning.
Create contract plans and specifications to ensure building performance
A step-by-step approach for integrating technologies into the different stages of design and execution.
Research into the manufacture of lightweight automobiles is driven by the need to reduce fuel consumption to preserve dwindling hydrocarbon resources without compromising other attributes such as ...safety, performance, recyclability and cost. This book discusses the materials being considered for lightweight automobiles and compares their characteristics and properties. Part One discusses materials for lightweight automotive structures with chapters on advanced steels for lightweight automotive structures, aluminium alloys, magnesium alloys for lightweight powertrains and automotive structures, thermoplastics and thermoplastic matrix composites and thermoset matrix composites for lightweight automotive structures. Part Two reviews manufacturing and design of lightweight automotive structures covering topics such as manufacturing processes for light alloys, joining for lightweight vehicles, recycling and lifecycle issues and crashworthiness design for lightweight vehicles. This book is a standard reference for practicing engineers involved in the design and material selection for motor vehicle bodies and components as well as material scientists, environmental scientists, policy makers, car companies and automotive component manufacturers.
The concept of sustainability has been expanding to all areas of economic activity, including construction. The Special Issue “Sustainability in Construction Engineering” provided a possibility for ...researchers to disseminate their new ideas and findings related to sustainable decisions in construction engineering as a complex discipline that involves designing, planning, construction and management of infrastructures. The topics raised interest of researchers all over the world and the current Special Issue received a great number of submissions from different institutions, countries and continents. In this Special Issue Reprint, 27 selected and peer-reviewed papers contribute to sustainable construction by offering technological, economic, social and environmental benefits through a variety of methodologies and tools, including fundamental decision-making models and methods as well as advanced multi-criteria decision-making (MCDM) methods and techniques that proved to be very suitable for sustainability assessment. The papers are mainly concentrated in five areas: sustainable architecture; construction/reconstruction technology and sustainable construction materials; construction economics, including investments, supply, contracting and costs calculation; infrastructure planning and assessment; project risk perception, analysis and assessment with emphasis on sustainability. Due to its broad scope, the Special Issue Reprint expects to attract a large interest from the research community.<false,><false,>
The construction sector consumes a massive amount of resources, produces a large volume of emissions, and generates large-scale waste. Earlier studies considered green, lean, and Six Sigma (GLS) ...approaches as being critical in the construction process for the optimum use of resources, cost reduction, quality improvement, and sustainability. Pakistan's construction sector is struggling to implement sustainable and improved construction processes. This work attempts to analyse barriers to the GLS construction process (GLSCP) through a literature review and expert opinion. During brainstorming sessions, a group of experts validated the barriers and developed contextual relationships among them using a questionnaire. An 11-level hierarchal model was developed by implementing interpretive structural modelling (ISM) methodology. The Matriced Impacts Croise's Multiplication Appliqée a UN Classement (MICMAC) technique was applied to delineate these barriers into the categories of ‘driving’, ‘linkage’, and ‘dependent’. While the findings indicate that all barriers are critical and play a role in hindering the application of GLS in the construction process, the top five critical barriers to GLS are an unstable political environment, lack of government policy, lack of customer involvement and awareness of GLS, lack of funds, and lack of top leadership support for GLS adoption. This work may assist the government, policy-makers, and managers by providing insights into the barriers and in developing strategies for the possible adoption of GLS concepts for sustainable construction and improved quality.
•Pakistan’s construction industry is facing challenges in sustainable construction because of a lack of green, lean, and Six Sigma implementation.•Regarding the barriers to green, lean, and Six Sigma, driving and dependence power and their interrelationships are framed by integrating ISM and MICMAC methods from a construction sector perspective.•An unstable political environment is a major barrier driving other barriers to green, lean, and Six Sigma implementation.•Lack of government support is the second most important barrier to green, lean, and Six Sigma implementation in construction, which is driven by an unstable political environment.•Implications for policy makers and managers are given to overcome the explored barriers.
Although automation has been actively and successfully used in different industries since the 1970s, its application to the construction industry is still rare or not fully exploited. In order to ...help provide the construction industry with an additional incentive to adopt more automation, an investigation was undertaken to assess the effects of digital fabrication (dfab) on productivity by analyzing the cost and time required for the construction of a robotically-fabricated complex concrete wall onsite. After defining the different tasks for the conventional and robotically fabricated concrete wall, data was collected from different sources and used in a simulation to describe the distribution of time and cost for the different construction scenarios. In the example, it was found that productivity is higher when the robotic construction method is used for complex walls, indicating that it is possible to obtain significant economic benefit from the use of additive dfab to construct complex structures. Further research is required to assess the social impacts of using dfab.
•Digital fabrication (dfab) has great potential to advance the construction industry.•Productivity is higher when dfab is used for complex structures.•No additional cost from robotic fabrication if the complexity of the wall increases•Dfab will transform current roles in the planning and execution of projects.•Further research is required to assess the social impacts of dfab.
A construção civil tem um papel de destaque na economia dos países, não sendo diferente na economia brasileira. Este setor é responsável por considerável movimentação financeira que impulsiona parte ...do desenvolvimento econômico. Sabe-se que, no referido setor, existe um grande índice de desperdício, retrabalho, necessidade de aprimoramento na organização de estoque, sequência das atividades e acompanhamento das operações. Diversos autores apresentam ferramenta lean construction para aumentar a produtividade, diminuir custos, aprimorar a execução das atividades e gerar valor por meio da análise de desperdícios nos serviços envolvidos na construção civil. Neste contexto, este artigo tem o objetivo de apresentar os resultados de uma análise preliminar de como a construção enxuta é aplicada no cotidiano de um grupo de profissionais técnicos, engenheiros, arquitetos, diretores, gerentes e outros envolvidos no setor da construção civil em uma cidade do estado de Minas Gerais.
