Building defects are lack or failure which the buildings do not achieve such as comfortable, safety, and function. Most of building should be occurs defects. Normally, building defects occur because many of factors that effect influence the buildings. There are four main reasons for the existence of defects in buildings. Firstly, inadequacy of the client brief. The architect as a professional is expected to assist the client in developing an adequate brief. Secondly, inadequacies of design. Most design errors of specification or choice of materials, juxtaposition of incompatible materials or components and inadequate provision of safe access for maintenance. Third, construction errors due to ambiguity or inadequacy of specification or supervision. Lastly, defects in materials and components can make defects occur. Generally, type of common defect occur are plaster cracks and associated with poor design. Many of the plaster cracks were found in wet areas and exposed to high temperature. Continuous wetting and drying of concrete walls in the wet areas encouraged contraction and expansion. Movements from contraction and expansion cracked plaster. Poor waterproofing caused moisture to travel from the floor onto the wall and plaster also cracked as a result. Moisture trapped inside the concrete forced cracks to form on the surface when moisture tried to find a way out.
