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.
