Hebei Province began special rectification of construction safety

In order to prevent and curb the construction of casualties, Hebei Province recently issued the “Review of Implementation Plan for Special Renovation of Construction Safety in 2014 and Prevention of Building Collapse Accidents”.

The special remediation highlights include construction hoisting equipment, excavation and support of foundation pits, tall formwork support systems, and scaffolding.

Among them, for a deep foundation pit project with a relatively large scale that exceeds a certain scale, the construction unit should organize experts to conduct demonstrations on the special program. During the construction period, special personnel should perform monitoring and monitoring of the deformation of the foundation pit.

According to the requirements of the plan, from May to August, the main responsibility of the project construction entity will carry out a complete self-check and self-correction of the project it has built.

From September to October, the competent department of construction at all levels will supervise and inspect the key enterprises and key projects in their respective jurisdictions on the basis of self-examination and self-correction of enterprises and projects. The Provincial Office of Housing and Construction will check the entire province.

At the same time, Hebei Province will increase penalties for violations of production safety. If failure to implement special rectification requirements results in significant accident hazards and causes casualties, it shall be dealt with according to law.
