在垃圾填埋场容量减少和环境意识增强的情况下，解构是减少建筑拆卸(C&D)碎片的有效手段。本文比较了马萨诸塞州联邦住宅楼的拆除成本和拆除成本。比较成本分析是通过系统分析之前在其他研究中报道的两个独立的住宅拆解项目，并补充马萨诸塞州最新的成本数据而发展起来的。研究表明，在马萨诸塞州目前的条件下，拆除成本可能比拆除成本高出17%-25%。该分析进一步确定了影响这些成本的参数，并对其进行了排名。这些参数对成本的影响顺序是：人工成本(生产率或小时费率)、处置成本(小费和运输费)以及拆解材料的转售价值。敏感性分析被用来确定这些参数的盈亏平衡点，从而使拆除变得与拆除在经济上具有竞争力。这项研究为废物管理计划的规划者提供了一种方法，以评估和开发促进C&D废物减少的战略。(C)2004爱思唯尔B.V.保留所有权利。
Deconstruction is an effective means for reducing construction demolition (C&D) debris at a time of diminishing landfill capacities and increased environmental awareness. This paper compares the cost of residential building deconstruction with the cost of demolition in the Commonwealth of Massachusetts. The comparative cost analysis is developed by systematically analyzing two separate residential deconstruction projects previously reported in other studies and augmenting with up-todate cost data for Massachusetts. The study shows that under current conditions in Massachusetts, deconstruction costs could be 17-25% higher than demolition costs. The analysis further identifies and ranks the parameters affecting these costs. These parameters, in the order of their impact on costs are: labor cost (either productivity or hourly rate), disposal cost (tipping fee and transportation), and resale value of deconstructed materials. A sensitivity analysis is used to identify the break-even points for these parameters such that deconstruction becomes economically competitive with demolition. This study demonstrates an approach for planners of waste management programs to evaluate and develop strategies for promoting C&D waste reduction. (c) 2004 Elsevier B.V. All rights reserved.
