最新消息。 旧金山大桥焊接裂缝，责任不在中国工程公司。也解释了，为何加州自己掏钱上亿刀修焊接裂缝补.

首先， 整个工程达65亿美金，追加不到1亿，也算reasonable。

加州交通局在2008年有"no-crack"规定。

当时中国公司常常发觉焊缝很难避免，(可以想象中国公司当时就要加钱)。 加州交通局为了省钱、赶工时，就修改了合同，把"no-crack"的规定放弃了。 允许工程完成后，有焊接裂缝。

平时大家老批评中国如何cut corner。 怎么样，遇到具体问题，人们操作方式与中国通常的方式也差不多。 人之常情，这本身就是一个普世。

In 2008, the no-cracks rule put the California Department of Transportation (Caltrans) in a worrisome bind. The Chinese firm hired to build the roadway routinely produced cracked welds that proved difficult to fix. Facing rising costs and increasing delays on a $6.5 billion bridge that was already years behind schedule and billions over budget, Caltrans sought advice about its options from a highly regarded expert in how metal fractures. He said some cracks can remain without compromising safety.

Caltrans then changed its contract and decided to put aside the welding code. Its fracture-critical bridge could now have cracks
