文章通过调研装配式住宅建筑在西北地区的情况,分析装配式与现浇式土建成本的指标差异,明确装配式住宅预制混凝土构件及安装为其造价成本的决定性影响要素。随后对预制混凝土构件分类,分析其采购成本、运输成本、装卸成本、库存成本、缺货成本的影响因素,最后提出了充分掌握地区建设政策、精确计算预制混凝土构件数量、妥善考察供货运距和贮存运距、明确装卸运输损耗责任义务、协商零星采购互惠条款等成本控制措施。 相似文献

产业化全装修住宅是绿色建筑的主要发展趋势。基于全寿命周期理论,结合实际工程,采用德尔菲法、层次分析法和净现值法对产业化全装修和传统全装修的全寿命周期成本效益进行计算分析。计算结果显示,昂贵的预制成本是影响产业化全装修住宅全寿命周期成本的关键因素。研究表明,因产业化技术不够成熟和产业链不够完整,决策和建安装饰成本偏高,导致产业化全装修住宅的全寿命周期成本高于传统全装修;由于能源消耗较低,预制构配件维修方便,产业化建筑拆除技术先进、回收利用率高,使得产业化全装修住宅全寿命周期运营成本和拆除回收成本较低。因技术效果良好,环境效益和社会效益可观,随着相关技术的不断成熟,全寿命周期成本将得以降低,产业化全装修住宅将成为我国住宅产业的重要形式之一。 相似文献

长期以来,住宅建设一直处于粗放型、劳动密集型的发展阶段,劳动强度大,工业化水平低,技术含量低.为此,国务院于1999年7月转发了建设部等八部委"关于推进住宅产业现代化提高住宅质量的若干意见的通知",将住宅产业化确定为我国住宅建设的发展方向.钢结构住宅可以使建筑构件生产工厂化、现场整体装配机械化、配套部品系列化、智能设备系统集成化、以及质量检测高科技化,符合住宅产业化要求.建设部于2001年12月印发的《钢结构住宅建筑产业化技术导则》,为我国钢结构住宅产业化的发展提供了技术支持,与传统的结构体系相比,钢结构住宅的发展为住宅产业集团的建立创造了条件. 相似文献

目前,我国政策大力支持发展装配式建筑,装配式混凝土建筑建造成本偏高是阻碍装配式建筑发展的首要因素。因此,结合先进科学技术对其成本进行有效管控至关重要。本文主要针对BIM数字信息化技术在装配式建造成本管控展开深入研究,通过AHP层次分析法分析装配式建筑建造成本影响因素权重,在设计阶段、构件运输阶段和现场施工安装阶段使用BIM技术对装配建筑成本进行控制,提出切实可行的管控措施,从而降低装配式建筑成本,推动智能建造和建筑工业化协同发展。 相似文献

基于住房支付能力的住房保障对象的界定 总被引:4,自引:0,他引:4
我国住房保障对象经历了从中低收入家庭向低收入家庭的演变.但对低收入家庭的不同理解导致政策实施中住房保障面期望值和实际值的巨大反差,如何界定住房保障对象成为一个难题.作为住房保障对象的低收入家庭,其界定依据是住房支付能力,而测度住房支付能力的关键是家庭月住房消费收入与目标住房所需月还款额.由此,构建基于收入增长的住房支付能力模型,并借助统计数据进行分析,测度我国不同收入阶层的住房支付能力,从而从消费者需求角度界定了我国住房保障对象. 相似文献

The housing market recovery has continued to gain momentum with activity accelerating and prices continuing to increase strongly on all measures in the latter part of 2013. This trend looks set to continue in the short‐term, with the latest survey data from RICS reporting strong growth in new buyer enquiries… 相似文献

A bstract . In 1967 and 1968, the United States Department of Defense instituted a program of "Nondiscriminatory Housing for Military Personnel." Data gathered in this program offer a unique opportunity to examine interactions between the armed forces and society in the housing market. The key factor explaining variations in the relative success of this program in different areas of the country appears to have been the importance of the military to the local economy. 相似文献

This paper develops a statistical method for defining housing submarkets. The method is applied using household survey data for Sydney and Melbourne, Australia. First, principal component analysis is used to extract a set of factors from the original variables for both local government area (LGA) data and a combined set of LGA and individual dwelling data. Second, factor scores are calculated and cluster analysis is used to determine the composition of housing submarkets. Third, hedonic price equations are estimated for each city as a whole, fora prioriclassifications of submarkets, and for submarkets defined by the cluster analysis. The weighted mean squared errors from the hedonic equations are used to compare alternative classifications of submarkets. In Melbourne, the classification derived from aKmeans clustering procedure on individual dwelling data is significantly better than classifications derived from all other methods of constructing housing submarkets. In some other cases, the statistical analysis produces submarkets that are better than thea prioriclassification, but the improvement is not significant. 相似文献

The housing market ended 2013 on a strong note, with momentum building in both prices and transactions. And market indicators point to further acceleration in activity and prices this year. As of March, annual growth in property prices was running at around 10% on the ONS, Nationwide and Halifax measures, with London prices were reported to have increased by 18% in the year to February… 相似文献

The distortions in the housing market caused by government intervention were attached by the Duke of Edinburgh in his Report this year. Tom Taylor (right), of the University of Wales Institute of Science and Technology, contrasts the Duke's conclusion that mortgage subsidies must be abolished with the analysis of John Parry Lewis in Economic Affairs October-November 1984. Mortgage interest tax relief, concludes Mr Taylor, will have to be removed. 相似文献
