ABSTRACT:

To live below the water is very fascinating for the mankind. There are so many architects who had tried to build underwater structures but couldn’t succed, because the construction part is the most difficult part in these kinds of structures. Environmental conditions underwater will affect the form of the structure, provision for ventilation and services. Underwater structure is a place where people who do not dive or do not swim can actually feel/experience the living underwater. With the melting of ice caps, the world will go underwater, so we should be prepared to build structures underwater in the future. Space for water and space for living can be perfectly combined. Because of vertical and horizontal freedom, the experience in the water neighborhood will stay dynamic. Terms such as real estate and movable property, however will acquire a completely new meaning. Based on case studies in foreign countries that have actually these kind of structures. Present study explains the constructional techniques and execution of these kinds of structures in short.

From the early ages, living underwater is very fascinating for mankind. There are many architects who had tried to build underwater structures but couldn’t fulfil their dreams, because of the constructional constraint as marine construction is difficult if compared to normal construction on land. Environmental conditions underwater will affect the form of the structure, provision for ventilation and services. Underwater structure is a place where people who do not dive or do not swim can actually feel/experience the living underwater. With the melting of ice caps, the world will go underwater, so we should be prepared to build structures underwater in the future.

There are some important issues related to underwater structures like design, environmental impact, technology, construction material, maintenance, construction and transportation to reach underwater structures.

Design: Environmental conditions underwater affect the form of the structure. Spheres and cylinders with hemispherical or ellipsoidal end caps are mostly used form in these kinds of structures which tend to be most efficient (resistance wise) when dealing with external loads (fluid pressure). A sphere is the most efficient structural form to obtain a minimum weight/displacement ratio and is common in very deep underwater structures, while a right circular cylinder reinforced with frames is the most common geometry used for shallow to mid depth range military and civil submarines. These structures should designed to be heavy-weather and seismic activity resistant and will easily resist a hurricane or significant earthquake event.

Environmental Impact: The design itself should facilitate for waste disposal and the well being of the environment; waste generated should be carefully observed. There should not be any discharge of waste material that would harm the surrounding marine life directly or indirectly. The construction itself should be designed in such a way, that there is minimum interference with the natural habitat hence; the marine life will not get disturbed. As the temperature of the inner part of the structure is more like to be higher than the temperature of the surrounding environment, heat transfer will occur mostly from the inner part of the structure to the adjacent surroundings, and thus would be accounted as heat loss. So the design should facilitate with the machine/instrument which will balance the temperature inside and outside of the structure.

Technology: The structure should designed in such a way that each of the individual part...
