Building Defects
BUILDING DEFECTS
PART 1
• Identify common building defects
• Identify the source
• Provide pictures, diagrams and sketches
• Suggest remedial action
• Show details that would have avoided the defect
PART 2
Generate a scheme for planned maintenance and provide a building checklist to ensure all necessary maintenance is carried out on a regular basis.
INTRODUCTION
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.
The number of defects we will be looking at is 15, and they are as followed,
• Wet Rot
• Dry Rot
• Subsidence/heave
• Thermal expansion
• Woodworm
• Architectural acoustics
• Damp(structural)
• Efflorescence/sub-florescence
• Chemical attack
• Freeze/thaw action
• Failure under load
• Splitting (wood)
• Condensation
• Fire spread
• Fracture
WET ROT
The first building defect we will be looking at is dry rot and wet rot. Wet rot is a fungal attack on wood that can have serious affects if it is not taken care of properly. Wet rot is dry rot that is after getting worse, dry occurs when wood has about 20% moisture content but if not taken care of at this stage and the wood gets damper (about 50%-60%) then wet rot sets in. Wet rot can be identified by looking at areas that are more likely to get it for an example a door joinery, the wood around the joinery would be a lot darker then the surrounding would also the wood which normally would be ridged would be spongy to touch these are all signs of wet rot. The problem would be when the wood dries out it would crumble into fine particles which would not be good if it was part of the load barring structure. We can also so break this down to three levels the molecular,
