GHD is playing a vital role in managing the long-term
structural integrity of the world’s tallest building, the Burj
Dubai Tower.
GHD was initially appointed in 2004, to design and review the
installation of a cathodic protection system to protect the
reinforced concrete piles and raft foundation, as well as to
provide advice on securing the longer-term durability of the
foundations for Burg Dubai.
Throughout construction, the GHD team has filled the critical
role of Verification and Testing Agency (IVTA) for the
developer, EMAAR Properties. The 160-plus-storey mixed-use tower is
nearing completion and stands at over 800 metres above sea
level.
The team was heavily involved with the construction of the Spire
above Level 156. The Spire is a complex steel structure with a
variety of columns, beams and bracing that are either welded or
bolted in place. Running through the centre of the Spire is a
welded steel pinnacle, which was jacked up after completion of the
Spire to reach the Tower’s final height.
Providing some insight into the dizzying scale of the building,
GHD's Hugh Cunningham observes, “Structural welding at this height
has never been attempted before, which leads to new challenges with
regards to the correct quality assurance and quality control
procedures. This demands special safety measures for each person,
including a full body harness and a double lanyard attached to
steel cable.”
The team has also provided input into the welding of the link
beams between the wings and centre core. And it has provided advice
on the fabrication and welding of a variety of decorative and
operational piping, and corrosion prevention.
