ASSIGNMENT QUESTION “With suitable examples, analyze and evaluate the importance of good building management for the development and continued maintenance of commercial and high-rise buildings in Malaysia from the standpoint of asset value appreciation, investment returns, and quality living and environment sustainability”. 1.0 OVERVIEW A tower block, high-rise, residential towers, apartment tower, office tower, apartment block, or block of flats, is a tall building or structure used as a residential and/or office building. In some areas they may be referred to as "MDU" standing for "Multi Dwelling Unit". High-rise buildings became possible with the invention of the elevator (lift) and cheaper, more abundant building materials.

Most North American style skyscrapers have a steel frame, while residential blocks are usually constructed of concrete. There is no clear definition of any difference between a tower block and a skyscraper, although a building with fifty or more storeys is generally considered a skyscraper. High-rise structures pose particular design challenges for structural and geotechnical engineers, particularly if situated in a seismically active region or if the underlying soils have geotechnical risk factors such as high compressibility or bay mud. They also pose serious challenges to firefighters during emergencies in high-rise structures. New and old building design, building systems like the building standpipe system, HVAC systems (Heating, Ventilation and Air conditioning), fire sprinkler system and other things like stairwell and elevator evacuations pose significant problems.
