佛州天价人行天桥坍塌现场,承包商早有诉讼
美国佛罗里达州迈阿密一条重950吨的新建行人天桥，于当地时间3月15日下午突然倒塌，最少8辆途经的车辆被压至变型，另有大批伤者被困，已造成10人死亡。
据中时电子报：美国佛罗里达州迈阿密一条新建行人天桥週四突倒塌，造成多人死伤。
这大桥在佛罗里达国际大学附近，计划明年初开放，总重950吨，长174英尺，造价1420万美元（约4亿台币），上周六才搭建完成。
高速公路巡逻队说，五至六辆汽车在天桥倒塌时被压碎。急救人员在急着在瓦砾中寻找生还人员，已将现场封锁。

=====================
使用加速的建筑方法建造
据《迈阿密先驱报》报导，这座桥预计于2019年初完工，将大学Modesto A. Maidique校区与斯威特沃特市相连，据估计有4000名学生居住在该校区。上周六他们才刚刚庆祝这座新桥主体安装完毕。
该天桥重达920吨，跨度174英尺，横跨7个车道。
根据根据该大学网站上关于桥梁的实况报导，建设费用为1420万美元。
佛罗里达国际大学的新闻稿强调了这座桥梁采用加速桥梁施工（ABC）方法建造的事实，该方法“降低了对工人，乘客和行人的潜在风险，并最大限度地减少交通中断。”
美国联邦公路管理局称，这种方法有助于“减少现场施工时间”，可用于修建或建筑桥梁，该方法旨在改善“旅行公众在（建筑）工作区的安全”，同时减少交通影响和与天气有关的施工延误。
大学说，它是美国历史上使用自行式模块化运输的最大人行天桥（也是第一个完全由自清洁混凝土构成的天桥）。
CNN报导，佛罗里达国际大学的论文显示，这座倒塌大桥被设计成可承受5级飓风，其耐用性应该超过100年。#

=======================
The statement added that MCM, which is based in Miami, would "conduct a full investigation to determine exactly what went wrong and will cooperate with investigators on scene in every way."
The company is also dealing with a lawsuit filed by a TSA employee, who claims a "makeshift" bridge for employees at an MCM construction area at Fort Lauderdale-Hollywood International Airport collapsed under his weight, severely injuring him.
Another company involved, FIGG Bridge Engineers, which designed the pedestrian bridge, said in a statement that it was "stunned" by the collapse.
"Our deepest sympathies are with all those affected by this accident," the FIGG statement said. "We will fully cooperate with every appropriate authority in reviewing what happened and why. In our 40-year history, nothing like this has ever happened before." FIGG is based in Tallahassee.
=================================
Bolton Perez and Associates, a third company involved in the construction of the bridge, is not commenting at this time.
====================================
BDI Engineering, a Colorado-based company, said it provided structural monitoring as the bridge span was put into place Saturday but added later that none of its personnel were at the scene on Thursday.
The company, which tweeted a video Saturday of the move and later took down the post, said it had "removed comments from our social media accounts out of respect for the individuals and families that have been affected by the collapse."
Its tweet on Saturday said that the firm was "thrilled to have performed structural monitoring during a spectacular bridge move."
