Basic Common Construction Process of Members
Mold capable of supporting stresses created by the steel is either delivered to job site or molds are located off site.
Required or preplanned pre-stresses are determined and required reinforcement steel is determined and set.
Proper concrete mix is determined and placed into molds. Self-consolidating concrete is massively used for ease of finishing.
Concrete is allowed to cure and reach a needed strength great enough to support the tension in the steel without cracking. Then steel is cut and member is removed from mold and is ready to install.
