The speed of erection is a vital factor in obtaining a return on the
investment by minimizing the cost of interest payments on the large capital
costs involved in such large-scale projects.Most tall buildings are constructed
in congested city sites with difficult access, and with no storage areas.
Careful planning and organization of the construction sequence become essential.
The story-to-story uniformity of most multi-storey buildings encourages
construction through repetitive operations and prefabrication techniques.
The progress in the ability to build tall buildings has gone hand in hand with
the development of more efficient equipment and improved methods of
construction, such as:
- Slip- and flying-formwork
- Concrete pumping
- The use of climbing tower cranes and large mobile cranes.
