Bridge Lifting and replacement of Bearing

So in some case bearings are placed after casting of superstructure (due various reasons e.g. non availability of bearings at time construction, change in design, delay in the project, etc.). So Installation of bearings has to carry out by lifting the superstructure. We have carried out installation of bearings of 95 spans for L&T (Rajkot – Jamnagar – Vadinar Road Project) on fast track basis (i.e. in 4 months).

Apollo Hospital – Gandhinagar

Problems

• Helipad on roof top will increase the loading and induce lots of vibration
• To locate affected structural components
• Redesigning of those affected structural components

Solutions Worked Out

• To locate affected structural component structural designer was consulted.
• They (Structural Designer) analysis the existing structure with additional loading due Helipad
• Based on analysis it was found out that only certain columns and footing of ground floor and first floor needs to be strengthen
• It was then proposed to increase size of column from 600 mm × 600 mm to 1000 mm dia
• It was also proposed to increase thickness of footing y 200 mm
