由于国内治理大型城中湖污染经验缺乏,因此武汉市后官湖景观绿化及配套工程项目工期控制存在较高风险,而且该项目采用了传统DBB项目管理模式,造成施工周期较长,也为该项目的工期控制埋下隐患。所以,在国内外治理复杂水域的工期评价研究... 由于国内治理大型城中湖污染经验缺乏,因此武汉市后官湖景观绿化及配套工程项目工期控制存在较高风险,而且该项目采用了传统DBB项目管理模式,造成施工周期较长,也为该项目的工期控制埋下隐患。所以,在国内外治理复杂水域的工期评价研究的基础上,结合我国湖泊治理的特点,立足于总承包商的角度,运用系统论中霍尔提出的三维结构,构建官湖景观绿化及配套工程项目工期评价指标体系,运用改进后的模糊分析法对其全寿命周期进行评价,并针对评价结果分析各因素对工期的影响程度,为工期控制提供了科学化、合理化依据。 展开更多

Considering that buildings represent 40% of greenhouse gases and approximately 10% of global gross domestic product, the target the building industry has to accomplish is to get to a high quality and low carbon living, by reducing carbon emission by 2050, as said by Energy Performance of Buildings Directive. Considering these needs, designers, manufacturers and construction companies should be able to make use of web and design tools for collecting and inventorying a large variety of environmentally friendly materials, through a specific database that encloses low carbon certified products and eco-labeled ones. The eco-labels are internationally identified as the best tools to encourage the spread of green products and low carbon notions, even if in Europe, there is no specific tool to be used. The project called LoCaMat (Low Carbon Material Database) will act as the first Italian and European database that encompasses multiple data on certified green materials to be used for the construction sector, making buildings climate change resilient, ensuring an efficient use of energy and resources, getting to a complete life cycle assessment for buildings materials and components, encompassing, for the first time, green data and every kind of environmental specs for sustainable design and green practice. 展开更多

With the rapid development of construction engineering and municipal engineering in recent years, water supply and drainage technology has gradually matured. Building water supply and drainage design contains the design of rainwater drainage, sewage drainage design, water supply design and fire water supply design. At present, the research on the life cycle assessment of urban drainage system is mainly focused on the sewage treatment plant, therefore in this paper we introduce the theoretical basis of life cycle assessment. In the era of information network, building information model(BIM) technology is widely applied to the design of building water supply and drainage, which and effectively improves the design effi ciency, and makes up for the traditional water supply and drainage design of a lot of problems. In this paper, we analyze the development trend of water supply and drainage engineering based on life cycle assessment and building information model. 展开更多
