Aiming high in Kuala Lumpur

Strainstall Malaysia has been awarded a major contract to incorporate its sophisticated structural monitoring equipment into the construction of what will be the fifth tallest building in the world.

The complex design of the prestigious Merdeka PNB 118 skyscraper development in Kuala Lumpur, Malaysia means monitoring during construction – and afterwards - is critical to the build.

This provides the contractor with important information about the building’s alignment during construction and provides a real-time early warning system, identifying areas of structural degradation throughout its lifetime.  

A full range of sensors and third party satellite technology will be employed to take measurements across the structure as it takes shape with instrumentation strategically positioned throughout the 118-storey building from the basement to the top of its spire (see graphic).

Monitoring has already begun and is expected to continue for at least the next ten years beyond the completion date in 2020.

The monitoring system will combine accelerometers, strain gauges for steel and concrete, a Global Navigation Satellite System (GNSS) positioning system and a weather station to provide crucial information on the building’s performance during the construction process and as a means of future long term health monitoring.

This data is fed into Strainstall’s Smart Asset Management System (SAMS) software which records and collates data in real time. SAMS will be integrated with the development’s own building management system to share information and provide warning of any events that fall outside acceptable parameters, allowing engineers to mitigate risk and take remedial action where required.

Damian Griffiths, regional monitoring solutions manager for Strainstall in Malaysia explains:

"With tremors being felt in Malaysia from seismic events all around Asia and an increased typhoon risk in the region, our long-term health monitoring system will provide a historic data library which can be brought up at any time. This information can be used as a means of comparison of the building’s response in addition to real-time alerts and alarms which might occur during such event."

SAMS was originally developed for large bridge projects but is now proving invaluable in the health maintenance of high rise buildings and this contract win follows a number of high profile monitoring projects by Strainstall in recent years, including a six year monitoring project of the world’s tallest building, the Burj Khalifa in Dubai.  

Damian adds:

"Strainstall Malaysia has a strong record of successfully monitoring large, complex structures and we are confident our system will offer complete transparency concerning the performance of this tower throughout construction, commissioning and beyond."

Strainstall Malaysia general manager, Jasper Lee adds:

"This flagship development represents an impressive engineering feat which will have a huge impact on the Kuala Lumpur skyline."
