Building components deteriorate and wear out with time and use. Planned maintenance is an asset management strategy to ensure buildings and their components function adequately, preserve the value of the building, satisfy legal obligations, and achieve best value in terms of built assets during the occupancy phase of the building. It is a complex and challenging activity that draws on the full range of building surveying skills. Key maintenance issues range from Component deterioration and failure to Government policy.
