Design and construction of skyscrapers

Abstract EN

Designing and construction of skyscrapers were always considered as complex projects.

This was because the designing and construction of skyscrapers required special considerations not only related to technological factors but also with respect to their safety and security.

The considerations of safety and security in the design and construction of buildings in general and tall buildings in particular have taken a new dimension following the tragic events of September11, 2001 leading to the collapse of World Trade Center (WTC towers).

An awareness and acceptance of the threat by policy makers, building owners and importantly the various players involved in the design and construction process from the architect to the structural engineer is necessary for the application of blast-effects mitigation technologies and design methodologies to be effective.

The engineering and the architectural professions thus have a strong ongoing need for proper guidance to develop and enhance safety and security of the tall building structures.

This paper examines the key recommendations proposed by the New York City Task Force (NYCTF).

It summarizes the key recommendations and provides an overall view of considerations relating to the design and construction of tall buildings in the aftermath of September 11, and puts forward recommendations through which it is possible to provide practical levels of enhanced safety and security.
