Labor Contract Head: Precast Construction – “Wolf” Has Really Arrived
In the past few years, there were not so many precast buildings, and the requirement for assembly rate was not high, with 30% being a common indicator.
To achieve this standard, it is basically only necessary to make the cast-in-place slab into a laminated board or add precast stairs.
Nowadays, the assembly rate is generally required to be above 50%.
In addition to the main components such as walls, slabs, stairs, balconies, etc.
, precast internal partition walls (ALC) are also used for the secondary structural parts.
Lao Zhang said, “For a high-rise building with a high assembly rate of about 30 floors, the main labor we can do is the basement, floors 1-4, the standard floor elevator shaft, and the precast post pouring part.
If we only do the assembly project of composite panels and precast interior walls, the formwork area of the main structure will be reduced by about 30%, and the labor unit price of the standard floor will be much lower.
The actual labor workload has not decreased much, such as the erection and dismantling of scaffolding, the laying of square wood formwork, the binding of steel bars, and the pouring of concrete.
