601 m pump height at Burj Dubai – and it's getting higher!
Earlier than expected, at the start of November 2007, a Putzmeister super high pressure concrete pump at the Burj Dubai reached the record delivery height of 601 m. At this height, in the most spectacular high-rise building project in the world, a wall of the central building core was concreted on level 155. The pump height is calculated from the length of the riser secured in the structure and the vertical delivery line including the tubular column and stationary boom. The actual concrete placement took place at a height of 585 m. An end to the high-rise concrete pumping has thus not yet been reached, but is in sight. The desired pump height has in the meantime – not least in view of the way the concrete pumps have been working so smoothly - been moved further upwards to 611 m. (Ill. 1514-1, -2 and 3)
The client, Emaar Properties (UAE), has commissioned a consortium managed by Samsung (Korea) together with BeSix (Belgium) and Arabtec (UAE) with carrying out the construction works on what will be the highest building in the world, at over 800 m. Turner Construction (USA) is responsible for the project management.
With three Putzmeister high performance concrete pumps, a sophisticated delivery line system, four non-ballasted stationary booms and challenging concrete mixtures, the carcass of the Burj Dubai has been under construction since the start of 2005. Due to the rapid progress in construction and the narrowing building structure as it rises upwards, three of the stationary booms have in the meantime been dismantled and one of the stationary pumps removed. (Ill. 1514-12)
A proper amount of trust in the know-how and reliability of the partner was required when Unimix - responsible for concrete production and delivery at the Burj Dubai - decided to commission Putzmeister AG with the supply and installation of the pumps and boom systems. Through earlier pump tests, Putzmeister had already determined that the concrete pumps and pipelines for delivery heights of up to 600 m were suitable at an output of around 30 m3/h. It was also known that the tip of the Burj Dubai would be erected in a lighter steel construction from level 156, for static reasons, and that only the decks would be concreted up to level 160 (611 m height).
High-rise pumping simulated in extensive preliminary tests
PM's preparations at the start of 2005 were correspondingly thorough as well as extremely time-consuming and human-resource intensive, both at the Aichtal Works and at the construction site in Dubai. On site, extensive tests were carried out with horizontally laid pipelines in a large series of tests and with the support of the local PM agent German Gulf Enterprises (GGE – see info box on page 11). The reason was to simulate the pressure behaviour and the expected friction of the concrete in the pipeline based on the later mixture breakdown and to convert it to the high-rise pumping. The tests were carried out using a series produced BSA 14000 HP-D high-rise pump and ZX delivery line

In the meantime, the base plate for the tower and the three tower wings was produced by truck-mounted concrete pumps with different boom reaches. The 7,000 m2 foundation is supported by 200 concrete piles (diameter 1.5 m) for the actual tower and 650 platform piles (cross section 0.9 m) for the wings. The piles reach a depth of up to 55 m. In total, 45,000 m³ of concrete was laid at the Burj Dubai for the foundation, including base plate. (Ill. 1514-9)
