Precast Concrete Stairs ~ these can be produced to most of the
formats used for in-situ concrete stairs and like those must comply
with the appropriate requirements set out in Part K of the Building
Regulations. To be economic the total production run must be
sufficient to justify the costs of the moulds and therefore the
designers choice may be limited to the stair types which are
produced as a manufacturer's standard item.
Precast concrete stairs can have the following advantages:†
Good quality control of finished product.
Saving in site space since formwork fabrication and storage
will not be required.
The stairs can be installed at any time after the floors have
been completed thus giving full utilisation to the stair shaft
as a lifting or hoisting space if required.
Hoisting, positioning and fixing can usually be carried out by
semi†skilled labour.
