Although concrete seems stark and cold, it may be the perfect material for constructing stairs in commercial buildings. But before making a decision, builders must weigh the pros and cons of using commercial concrete stairs. There is no denying that many new commercial projects incorporate concrete structures into their designs.

Is offsite construction the answer to jobsite safety concerns? While some folks commonly think of precast as grey concrete, used for sewer systems or structural elements, it can also be used to construct entire buildings, including schools, office structures, and condominiums. Precast concrete is an air barrier and a vapor retarder.

When concrete is fresh and in its liquid state it must be restrained within a mould in order for it to set in its required shape. A smooth outer surface provides the main support for the concrete as it sets. Formwork is the term used to describe this mould. For most in-situ pours, the formwork is made of wood.
