ABSTRACT
Commercial concrete high1ises are characterized by the presence of a large number of similar horizontal components (or typical floors) consisting of a number of vertical subcomponents (or columns and walls) and a single horizontal subcomponent (or slab). These are served by one or more elevators and stairways generally arranged in vertical cores running centrally through the slabs. This configuratio11 lends itself to a constant cycle construction strategy. In consta11t cycle construction, the intent is to optimize the workflow so as to have the same duration for each subcomponent from one floor to the next. To achieve this optimized workflow, it is imperative in the planning stages to choose the right blend of construction methods so as to provide continuity for work crews, allow for cycling of complex forming systems without having to transport them to ground level after each use, and allow optimum use of shared resources such as cranage, given the project's physical context such as typical floor dimensions, available work space, site location, storage areas available, expected environmental conditions and the regulatory climate.
