Abstract

Despite that Building Information Modelling (BIM) is often praised as a whole life-cycle methodology, possibilities for deconstruction are consistently overlooked. This study demonstrates what those possibilities may be. Previous studies showed that: deconstruction practices pose several site-based challenges; BIM implementations may help practitioners to address such challenges; and activity theory offers a framework to understand BIM implementations. We aimed to explore how deconstruction practices can be reorganised with BIM by applying an activity-theoretical perspective to a rather unique case-study. The selected case concerned the deconstruction of a nursing home so that many of its elements could be reused to construct a school. During this project, we implemented BIM in three essential activities: analysing existing conditions, labelling of reusable elements and planning deconstruction. The implementations resolved initial problems related with the use of traditional drawings, schedules and instructions. They nevertheless also triggered several additional problems that we attempted to address in successive steps. The organisation of the activities so evolved, which culminated in the formation of three new BIM uses for deconstruction: “3D existing conditions analysis,” “reusable elements labelling” and “4D deconstruction simulation”. These concepts complement existing BIM use taxonomies and can be appropriated in future deconstruction projects.

摘要

尽管建筑信息模型（BIM）通常被认为是整个生命周期方法，但始终都忽视了解构的可能性。这项研究表明了这些可能性。先前的研究表明：解构做法带来了一些基于站点的挑战；BIM的实施可以帮助从业者应对此类挑战；活动理论为理解BIM实施提供了一个框架。我们的目的是通过将活动理论的观点应用到一个相当独特的案例研究中，探索如何用BIM重组解构实践。选定的案例涉及对养老院的解构，因此其许多要素都可以重新用于建造学校。在此项目期间，我们在以下三个基本活动中实施了BIM：分析现有条件，可重复使用元素的标签和规划销毁。这些实现解决了与使用传统图纸，进度表和指令有关的初始问题。但是，它们还引发了我们尝试在后续步骤中解决的其他一些问题。活动的组织方式如此演变，最终形成了三种新的BIM解构用途：“ 3D现有条件分析”，“可重用元素标记”和“ 4D解构模拟”。这些概念补充了现有的BIM使用分类法，并且可以在将来的解构项目中使用。但是，它们还引发了我们尝试在后续步骤中解决的其他一些问题。活动的组织方式如此演变，最终形成了三种新的BIM解构用途：“ 3D现有条件分析”，“可重用元素标记”和“ 4D解构模拟”。这些概念补充了现有的BIM使用分类法，并且可以在将来的解构项目中使用。但是，它们还引发了我们尝试在后续步骤中解决的其他一些问题。活动的组织方式如此演变，最终形成了三种新的BIM解构用途：“ 3D现有条件分析”，“可重用元素标记”和“ 4D解构模拟”。这些概念补充了现有的BIM使用分类法，并且可以在将来的解构项目中使用。
