The superstructure is the part of the building that is above ground or, supported by the substructure of foundations.
The main principles of a superstructure are to be:
• Weather Proof
• Secure
• Attractive
• Fire resistant
• Sound proof
This is achieved by various means, but one of the main principles is that the external envelope of the building n eeds to be sealed from on all sides whilst still allowing the building to breath.
The main strength of the building generally comes from the external walls, but as the building get bigger it will need more structural walls as internal walls. In this picture we can see the main supporting parts of a concrete superstructure. This will be made weatherproof by adding cladding, windows and doors.
Roofs need to both protect from rain and snow, as well as keep heat in the building, a pitched roof lets the rain run off, while using overlapping tiles allows for movement in the roof with heat expansion an d vapor to escape.
Sound proofing can be achieved by using a dense insulation such as celotex, cavity walls, stud walls and floors can have this built into th e gaps to help increase the efficiency of the dividing wall or floor.
Looks are also important to a building, by failing to make the structure attractive the designer may not be able to sell the building and an un-attractive building may have a negative impact on the residents, workers or people who use the immediate vicinity. Poor design has also been linked to crime rates by some people and urban redevelopment can be used to improve an area.
Fire resistance is achieved by choice of materials, such as treated timbers and plasterboards that resist the spread of fire.
