The construction phase ends once the commercial construction has been completed. Then the groundbreaking will be conducted. During this meeting, decisions are made in regards to work hours, material storage, site access, and quality control. When the first part will be cast completely, the rest part should be started. The construction phase of the process begins with a meeting organized by the superintendent. But as we know that dropping concrete more than 5 feet height is not allowed because it will cause segregation, we should create formwork within 5 feet height.
For example, if the beam height is given in the drawing is 1′-6″, the casting height of column and formwork will be 8′-6″. If the slab contains beam, then concrete has to be poured upto the beam bottom level. The floor height is normally kept at 10 feet.
Lets look for another example, C2-8#20 mmØ +10#16 mmØ and stirrup – 10 mmØ the column will have 8 numbers of 20 mm dia bar and 10 numbers of 16 mm dia bar for vertical reinforcement and (4″+6″) c/c means the middle half portion of clear height of column will have 6″ center to center spacing of stirrups and the upper one-fourth as well as bottom one-fourth height of the columns clear height will hold stirrups at 4″ center to center spacing.Īdditional notes such as lap length for column steel of different diameter etc will be given in the sheet of structural drawing.
