寒冬时节，北京市西城区三里河一区28号楼正紧张施工，这是一栋全面拆除后重新打地基、在原址 上新建的住宅楼。等到2月份，原来的居民们就可以住回崭新的28号楼。 拆除前的三里河一区28号楼始建于1978年，共3个单元54户。经过近50年使用，老住宅存在结构老 化、外墙开裂、阳台风蚀龟裂等安全隐患。居民们苦不堪言：给排水、燃气等管线堵塞锈蚀漏水；未做 外墙保温造成冬季供暖室温不达标；厨房、卫生间空间狭小；室内外缺少适老化设施。居民们都期盼着 改造。 我国正持续推进城市更新，城市更新八项主要任务中，有一项是加强既有建筑改造利用。《中共中 央办公厅 国务院办公厅关于持续推进城市更新行动的意见》要求，稳妥推进危险住房改造，加快拆除 改造D级危险住房，通过加固、改建、重建等多种方式，积极稳妥实施国有土地上C级危险住房和国有 企事业单位非成套住房改造。三里河一区28号楼被认定为D级危险住房，是以原拆原建方式进行改造的 一处典型案例，可为全国其他地方危旧住宅楼原拆原建改造利用提供借鉴。 重建过程中应用"工厂制造+现场安装"智能建造模式，实现像造汽车一样造房子，大大缩短工期。 三里河一区28号楼项目由中国建筑国际集团承担重建任务 ...
