by government authorities at any point in time. An adaptive reuse score of 50% or above is considered high. A low ARP score is anything below 20%. Anything between that range is considered moderate. Shen and Langston devised this concept of ARP as "rising from zero to its maximum score at the point of its useful life, and then falling back to zero as it approaches physical life". When the "current building age" is identified to be close to or end of its useful life, is the right time for builders to commence redesign. Methodology of adaptive reuse Buildings have a high impact on the environment, the economy and our society. Adaptive reuse has several benefits to mitigate those high impacts. Adaptive reuse projects are, in many ways, different from conventional new construction projects and must be planned and managed differently. Building condition assessment Before starting an adaptive reuse project and even considering refurbishment, it is important that the condition of the existing building is thoroughly assessed. A condition assessment primarily inspects a building's structural integrity, roofing, masonry, plaster, wood-work, tiling and the mechanical, electrical and plumbing systems. The in-depth inspection of buildings can be expensive. Nevertheless, building condition assessment is critical to the success of an adaptive reuse project and must not be avoided at any cost because this expense is insignificant relative to the injury or loss of life that a building failure might cause. One logical reason, as explained by the American Society of Civil Engineers, is that even a very well constructed building could undergo serious deterioration and eventually failure, if proper maintenance is not performed in the operational phase of the building. For example, in the year 1984, the New York City Passenger Ship Terminal went through a thorough inspection and was identified with extreme corrosion in its exterior steel columns (100% of web loss and 40% of flange loss). This condition posed a threat to the public safety and had to undergo immediate restriction of live load in spite of additional bracing of critical bents. Such inspections conclude with the preparation of a detailed report summarizing the findings of the investigation. The direct inspection of the structural system is required to a certain degree which is decided by the judgement of an experienced civil engineer. Survey of neighborhoods After identifying the stability and soundness of a building, it is important to survey the neighborhood
