- Steel Beam Installation: While lifting house, structure steel beams will be fixed strategically so that it can support weight of house.
- Timber Shoring: Temporary supports in the form of timber framed styes will be used to support loads of the house as the steel beams are placed.
- Hydraulic Lifting: The house will then be lifted slowly with help of several hydraulic jacks of a high tonnage than those used in lifting individual foundations.
- New Stumps and Piers: When the house is lifted, new concrete stumps or steel piers will replace the elevated ones at required level.
- Lowering and Bracing: The house will then be very delicately shifted and placed on new stumps or piers.
- Earthworks and Footing Construction (if applicable): In relation to the project’s objectives, the ground may be dug beneath the new columns to gain more space under a house. Sometimes new footings could be cast for the future expansion of the construction.
- Permanent Connections: This house will be permanently bolted to new stumps or piers as case maybe. In the case of steel piers, this may entail welding, for instance, of girder couplers for increasing extent of the beam.
- Final Touches: After that, if the house is built on a new foundation, then the steel bracing will be taken out and if required then plumbing and electricity connections are also done.
