Question

The construction of a high rise structure will require a fixed tower crane

1. What are the design procedure steps to determine if the crane requires a deep foundation or shallow footing.
2. What are the soil properties that are required for the design?

Answer 1

Tower cranes have become an integral part of construction industry due to changing nature of building heights. For buildings which are taller and larger, lifting materials and to achieve speed in construction tower cranes are used. Following steps are generally adhered to in determination of type design of footing.

- Study of various foundation types and criteria for tower crane foundation

- examine the load capacity, self load, building nature, location, soil properties

- development of optimal foundation design for crane

- Analyzing various designs developed to arrive at optimal design

Following properties are analyzed for design:

- foundation design recommendation

- bearing capacity

- compaction properties

- lateral strength

- permeability

- frost depth
