最新消息。 舊金山大橋焊接裂縫，責任不在中國工程公司。也解釋了，為何加州自己掏錢上億刀修焊接裂縫補.

首先， 整個工程達65億美金，追加不到1億，也算reasonable。

加州交通局在2008年有"no-crack"規定。

當時中國公司常常發覺焊縫很難避免，(可以想象中國公司當時就要加錢)。 加州交通局為了省錢、趕工時，就修改了合同，把"no-crack"的規定放棄了。 允許工程完成後，有焊接裂縫。

平時大家老批評中國如何cut corner。 怎麽樣，遇到具體問題，人們操作方式與中國通常的方式也差不多。 人之常情，這本身就是一個普世。

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
