Building Defects Essay
• Identify common building defects
• Identify the source
• Provide pictures, diagrams and sketches
• Suggest remedial action
• Show details that would have avoided the defect
Generate a scheme for planned maintenance and provide a building checklist to ensure all necessary maintenance is carried out on a regular basis.
In this project we will be looking at many different kinds of building defects that would be commonly seen in the construction industry. As well as going into detail about the different types of defects using images, cad drawings, and photographs we will also be looking at how to spot the early signs, and how, once a defect has been noticed to fix them.

SUBSIDENCE/HEAVE Another building defect that is common in a number of countries is subsidence and heave. Even though masonry is a very strong and tough material once it is set to a form it cannot take a lot shear or tork pressure. When we look at how subsidence and heave can affect masonry it is all down to how the earth around it moves in different ways. For a building to be affected by subsidence or heave it all depends on the type of soil on which it has been constructed on, and what type of vegetation surround it.
Some clay is strong enough to support a building of four storeys on a simple foundation. But they shrink when their moisture content decreases and swell when it increases. Slight movement of houses founded on these soils is therefore inevitable as a result of seasonal changes in moisture content: downward movement or subsidence occurring during the summer and upward movement or
