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.
