Did the parking lot in Guiyang collapse because the construction team cut corners?

Can only say that it is possible, but there are many other factors. Specific things should be analyzed in detail. Collapse accident is one of the five common accidents in building construction, which refers to the accident that an object exceeds its strength limit or damages the stability of the structure under the action of external force or gravity. Construction collapse accidents mainly include: the instability and collapse of cast-in-place concrete beam-slab formwork support, the collapse of earth and stone caused by the instability of foundation pit slope, the collapse of demolition project, the collapse of crane and other lifting equipment, the poor quality of the wall on the construction site, and the collapse of the roof of the project under construction.

So, what is the cause of the collapse? Unreasonable design or calculation error of engineering structure.

Before construction, feasible construction organization design and special construction scheme were not compiled, specific safety technical measures were not disclosed, and specific construction projects were not evaluated and demonstrated by experts. The structural design of scaffolding, formwork support and lifting equipment is unreasonable or miscalculated. The building structure has poor quality, poor safety performance, unstable foundation and uneven settlement. The supporting connection (welding) of the building structure is not firm, and it is unstable due to overload, external impact or serious eccentric load.

Scaffolding and tall formwork supporting frame structure do not meet the design and specification requirements, and the overall safety and stability are poor, which is unstable due to overload or serious eccentric load, external impact or vibration, and failure to dismantle the frame according to procedures. During foundation pit excavation and earthwork excavation, the earth wall did not slope (even negative slope) as required, and there was no support or poor support. The soil quality is poor or seeps into groundwater and surface water, and the soil wall cannot bear huge lateral pressure or collapse due to unstable landslides caused by external vibration and impact.

Lifting equipment collapses due to poor technical safety performance, insufficient structural strength, imperfect safety protection device, poor combination of vertical crane and building, overload, collision, overload or illegal operation. The working environment on site is poor and there are no safety protection facilities. The construction site management is lax, and various quality and safety management systems become a mere formality. One-sided pursuit of economic benefits, cutting corners and poor construction quality.
