After deadly construction accident in China, how high will the blame reach?

The investigation of a construction accident that caused 74 deaths in the Chinese province of Jiangxi is set to end the political careers of many local officials, but the question remains of how high the blame should go.
Local police have detained 13 people since the accident at a power plant under construction as a preliminary investigation zeroes in on how the building company rushed the job.
Xinhua said authorities had identified 68 of the 74 victims, with the youngest aged 23 and the eldest 53.
Most of the dead had been working on an interior concrete wall of a massive circular cooling tower 70 metres up when the scaffolding collapsed on Thursday morning, resulting in one of China’s most serious industrial accidents in years.

In a statement issued on Saturday, the State Administration of Work Safety of the State Council said early findings suggested that a shortened time frame for the project, hasty construction and mismanagement all played a role in the disaster, without giving further details.
