House lifting: Economic and Environment Friendly Method for Foundation Repair
Abstract— Demolition of a house needs a strict attention and supervision to carry out the demolition and hen new construction is done. The project study includes the process of house lifting and new construction of building. Estimation, drawings are prepared for both house lifting and new construction of building. Drawings are prepared in accordance with the site visited for the house lifting. From the drawings estimation of house lifting method and new construction are done, which gives the total cost of both methods.The project study will give us the idea to adopt a particular method on the basis of feasibility, economy in cost & time and practicability.
Keywords— Demolition, House Lifting, Economy, Foundation Repair.
In the field of civil engineering there are different techniques used conventionally for the repair and restoration of foundations. Conventional methods used for the repair of foundation are underpinning, soil replacement etc. are costly, time consuming and also may result in damage to the superstructure.
Nowadays repair of foundation is done with new techniques known as lifting and shifting. In this technique the building is lifted with number of jacks and new foundation are constructed.
This technique is based on the relocation of structures by lifting it with hydraulic jacks. By raising the structure with jacks, we can also provide new foundation to the building or also strengthen the building foundation. It will result in increase of stability of the superstructure and life span of the building. This technique is economical as compared to the techniques used conventionally in the repair and restoration of the foundation. But this method damage the superstructure may also be minimized.
This technique was introduced for the first time in Philadelphia, Pennsylvania 1799 for the purpose of moving a building.
London’s famous monument marble arch built in 1847 was originally the entrance to the newly rebuilt Buckingham palace. It was found to be narrow for the state coach, and was moved to its present location of Hyde Park in 1851.
