What is a construction defects and why are construction defects still so prevalent in the construction industry? A construction defect is a defect or deficiency in the design, construction, or materials on a construction project. Broadly speaking, construction defects fall two categories: defects that affect the performance of the structures, and defects that affect the appearance of the structure. The figure 2.1 showing the defects theories. Defects that affect the performance of the structures can be categorized, broadly, in two additional ways: defects that allow water into the structures, and defects that make the building structurally unsound or weak and thus less resistant to wind and earthquake. Although there are dozens of examples, a few will suffice:  A window or door that installed without proper weatherproofing so that water intrudes into the building would be a construction defect.  A balcony that is sloped toward a house so that water drains into the house when it rains would be a construction defect.  A shear wall that was not nailed properly would be a construction defect.  A foundation slab that was installed without a vapor barrier underneath to prevent water from coming up through the slab would be a construction defect.  Soil that is compacted less than the degree of compaction required by the soils engineer would be a construction defect.
