Tower Crane Foundation Design Xls _verified_

A 35-story residential tower in soft clay. The site team planned a 5m x 5m x 1.5m pad foundation for a crane with a 200 tm overturning moment. The geotech report said 150 kPa bearing capacity.

Based on the site and crane loads, you input a trial design. This is often an iterative process within the spreadsheet.

During the tender phase, you may receive 50 different crane models from different suppliers. Manually calculating overturning moments for each is impossible. A well-structured XLS allows you to change the crane type (e.g., Potain MD 560 vs. Liebherr 630 EC-H) and see updated foundation dimensions in 10 seconds.

Tower crane foundation design is the engineering discipline of creating a reinforced concrete substructure that safely transfers all loads from a tower crane—including self-weight, lifting loads, wind forces, and dynamic effects—into the supporting ground. The foundation ensures the crane remains stable under all operating and non-operating conditions, preventing settlement, sliding, or overturning throughout its service life.
