Design-Life Integrity

The past two decades have seen a remarkable increase in the rate of construction of ‘super-tall’ buildings in excess of 300 m in height. A large number of these buildings are in the Middle East or in China. Dubai has now the tallest building in the world, the Burj Khalifa, which is 828 m in height, while in Jeddah, Saudi Arabia, the Kingdom Tower is currently under construction and will eventually exceed 1000 m in height.

Super-tall buildings in excess of 300 m are presenting new challenges to engineers, particularly in relation to structural and geotechnical design. Many of the traditional design methods cannot be applied with any confidence since they require extrapolation well beyond the realms of prior experience, and accordingly, structural and geotechnical designers are being forced to utilise more sophisticated methods of analysis and design. In particular, geotechnical engineers involved in the design of foundations for super-tall buildings are leaving behind empirical methods and are employing state-of-the art methods increasingly.

The worlds tallest buildings have either ‘Raft & Mat’, ‘Compensated Raft’, ‘Piled’ or ‘Piled Raft’ foundations

These type of building systems create challenges both during and after the construction phase. Today’s structural Engineering fraternity is facing compounding issues that threaten the design-life cycles of these superstructures. For example Delayed Ettringite Formation (DEF) or Alkali-Silica Reaction (ASR) are occurring in many super structures around the world & it is becoming a highly costly, exercise to overcome these destructive & persistent problems. In many cases demolition has been the only option.

Biorok Construct is building an internationally accredited team of highly experienced Construction Engineers that focus on the integrity of the concrete.

We provide independent Structural Lifecycle Analysis on tall buildings including Dilapidation and Building Condition Assessments and a Forensic and Diagnostic Service
