-**Construction process and phasing** One contractor builds large quantities of this type of building, so project management and control techniques are used in order to increase productivity and to diminish cost. When constructing the vertical reinforcing bars are usually first placed into position before laying the masonry units. Then, the horizontal bars can be placed in horizontal mortar joints. Finally, vertical reinforcement is grouted as the work progresses. With respect to equipment the following is commonly used: concrete mix, trucks, travelling crane, winch, pneumatic cramp.This building is not typically constructed incrementally and is designed for its final constructed size.+**Construction process and phasing:** One contractor builds large quantities of this type of building, so project management and control techniques are used in order to increase productivity and to diminish cost.

Bending of reinforcement bars Bad reinforcement detailing at the corners or intersection of walls.Insufficient concrete covers for horizontal reinforcement.+**Construction issues:** Partial grouting in vertical reinforcement.
