Non functionality

A buildings life is not unlimited. As the building ages, it deteriorates and hence will need a repair for performing its functionality. A functionally compromised and aesthetically poor building will need upgradation. The building should be structurally safe as well and hence structural repairs are inevitable.

In developed countries, periodic inspection and regular maintenance are mandatory as per the building rules. A stability certificate is mandatory for old buildings to be continued to be used. This keeps the building safe against failure. Such rules do exist in some of Indian city bylaws as well but rarely are they stringent.

Many clients prefer to repair an old building than rebuilding due to affordability reasons in this time when the prices of construction materials are sky rocketing.


Functional changes

Many times, the functional use of the building change and the load carrying capacity or demand of the building changes as well. In India, it is quite common that a residential area develops in to a commercial place and the owner wants to convert an old house in to a commercial space.

These demands strengthening of structural members by adding beams or any other structural means.


Sometimes, a major rehaul may not be needed. However, it is important that a structural engineer looks in to the load demand change and rework the capacity of members.


Upgrades & alterations

Strengthening of the structure may be needed when there are upgrades and alterations needed. The kind of alterations can be addition of lifts or stairs. Changing the wall layouts and so on.

All of these modifications, results in changes in the loads and the load path or the load transfer mechanism. It is mandatory that a structural engineer is on board and he or she looks in to the changes and ensure the changes can be safely incorporated.


Accidents

Sometimes, an accidental collapse or failure of a building or a structural member force repair. It can also be a natural disaster like earth quake that creates the requirement of refurbishment.


Meeting the building rules

Many owners violate the building rules and build initially. Later there may be requirement from the authorities to demolish the deviated portion. This will force the owner to break structural members which will need a structural expert’s attention.


Historical Value

Some buildings are heritage buildings and it has a huge historical value. Such buildings need maintenance and modifications over a period of time. Many such buildings are government owned buildings. Archaeological Survey of India or any related government agency will look after the maintenance requirements of such buildings.


Some buildings will also be sentimental to a client due to various reasons like the building being built by his parents or some one he values or even a school he studied.


These are only some of the reasons that demands refurbishment of a building. There can be many more reasons, specific to a project or a building. This needs to be taken up on a case by case.


Many building owners are not sure of how to go about the refurbishment works. They think that a civil or a structural engineer or a building contractor can do this with out any information from their end. This is not right. The entire information related to the existing building will be needed to safely and efficiently undertake these kinds of repairs.


Also, most consultants are not technically equipped to understand the refurbishment needs. Many are skeptical to take up this kind of work as the client is not really willing to spend money on consulting as they are not really aware of the needs and challenges involved and the value an experienced consultant can bring in.
