Rehabilitation of Older Existing Structures
The human body becomes deteriorated upon ageing. To a certain extent, the problem can be remedied by taking necessary preventive steps at the appropriate time.
This is exactly the case with buildings. As time passes, the condition of buildings also becomes deteriorated. Unless corrective methods are taken, it may so happen that the safety of the building itself may be jeopardized.
There are other factors that necessitate renovation. These are accidents, environmental factors, alteration to structures, etc. The construction associated with already-constructed structures is called renovation. Some people call the process of rehabilitation "Forensic Engineering." The role of the engineer is just like that of a doctor trying to diagnose the disease of a patient and then recommending corrective treatment. Maintenance of constructed structures includes preventive care, repairs, and rehabilitation.
Rehabilitation of structures is a multi-disciplinary activity. The concerned engineer should know the design aspects, environmental factors, construction procedure, and about building materials. The rehabilitation of existing structures is a more complicated and sophisticated assignment than new construction.
