Forensic Distress Evaluation of Cadets Block PAF Academy Asghar Khan

Abstract

Water seepage is a potential hazard to buildings worldwide and in particular PAF Academy Asghar Khan. It has led to lots of civil actions and the Court general relies on expert opinion on the finding of facts. In establishing the cause of action, identification of the sources of water seepage is usually more important than that of the causes of water seepage. Both the external sources and the internal sources of water seepage may be identified by carryout out forensic evaluation of building. In the broad sense of the term, the common objective of forensic engineering is to diagnose problems and remedy them, making the structure sound and serviceable. In the literal sense of the term, the primary objective of forensic engineering is to identify the source of the noted problem and assign responsibility for thefailure. In the Code written in 1780 B.C.E. by Hammurabi, the ruler of Babylon, it states "If a builder builds a house for someone, and does not construct it properly, and the house which he built falls in and kills its owner, then that builder shall be put to death."Clearly, the need to determine the causes of building failures is a longstanding one with serious, sometimes dire, consequences. In daily practice, the forensic engineer's understanding of design and detailing practices, material properties, investigative techniques and construction practices dictate his or her ability to comprehend and properly diagnose problems. Forensic building is needed to examine the affected building structure components to assess the structural integrity. This paper highlights some of the studies involved on affected concrete structures in various building types where the non-destructive test (NDT). The structural integrity can be evaluated based on the extent of deterioration from the experimental results.Nondestructive test methods (NDT) are available for the assessment of many types of defects in existing structures including: the evaluation of reinforcing steel corrosion, determination of defect location, accurate assessment of the member sizes, and reinforcement locations.By not carrying out unnecessary and/or unreliable tests, overall cost and time can be reduced. This may ultimately assist the public to resolve the problem of water seepage in buildings.
