Relocating slab tables quickly
Dubai, the metropolis on the Persian Gulf, has been expanding relentlessly for years. Near world-famous buildings such as the Burj Khalifa, another interesting building is currently being erected as part of the modern urban development project at Dubai Creek Harbour. When completed in the summer of 2019, the twin towers at Creekside 18 will house modern shopping arcades and about 480 apartments.
The prestigious construction company Al Naboodah Construction Group had already been awarded the contracts for a number of other projects at Dubai Creek Harbour and relies on technical solutions and local support from MEVA.
Underground fresh water supply
To supply the future residents with fresh water, underground water tanks were built. The tanks, with a height of approximately 8 metres, extend over both basements of the twin towers. The ideal formwork system for the wall thickness up to 0.60 metres was quickly found: Mammut 350. The high large-size panels and a fresh-concrete pressure load of 100 kN/m² enable the pouring time to be shorted significantly compared to other systems. Using the Triplex push-pull prop, the wall formwork was aligned to withstand tensile and compressive forces to ensure that the construction was vertical and able to withstand high wind loads.
Twin towers under construction
The two towers have an identical design and extend over a total of 37 storeys. Besides water tanks, parking spaces will also be available in the two basements when the towers have been completed. Various shops will be located on the ground floor and the first floor. The walls of these floors are 5 metres high, whereas heights of 3.40 metres are planned for the apartments in the upper levels.
The building’s columns and walls were formed using AluFix wall formwork. Thanks to their lightweight aluminium section, the large panels with heights up to 3 metres can be moved by hand. Thus, on this construction site it was again possible to save valuable crane time, which was then available to move large slab tables. This well thought-out concept helped the engineers responsible make rapid progress.
In this project the slab thicknesses vary between 0.23 and 0.60 metres depending on the construction phase, as slabs with very high load-bearing capacities are required in the lower floors in particular due to the high loads. By using MevaDec slab formwork, construction companies can rely on a stable and, at the same time, flexible formwork system that is suitable for almost all slab thicknesses found in building construction. The number of props is predefined by the system in order to ensure the highest level of safety even when very high loads are encountered. This aspect was particularly advantageous in the lower floors. Here, the 0.60-metre-thick slabs were supported by EuMax props from MEVA.
For the floors above, the architects who designed Creekside 18 planned 0.23-metre-thick slabs. Based on the MEP shoring tower, slab tables were prepared in conjunction with aluminium beams. With uniform wall heights of 3.40 metres, the work with these standard MEVA slab tables is progressing rapidly, as hardly any adjustments have to be made to the slab formwork for the next storey. This benefit also convinced the engineers of the Al Naboodah Construction Group during the contract award process because the standard slab tables promise reliable usage and quick relocation of the slab formwork. It is thus possible to assemble the formwork for each storey in only five days.
Relocating slab tables quickly
“The slab formwork planning was a special challenge for us. The large and heavy slab tables with a length of 3.30 metres and a width of 11.40 metres as part of our project-oriented solution are important for rapid construction progress,” explained Ric Jayson Mendoza, the MEVA engineer responsible. This allows the slabs of the top
35 storeys to be built quickly. The SAS quick-lowering system of the MEP shoring tower lowers the props by 1 cm with a single hammer blow and returns automatically to its original position during stripping. Equipped with MEP transport walers, it is then possible to move the slab tables to the slab edge and transport them to the next point of use by a crane. The tables are positioned and fixed in place again in order to pour the extensive slab areas quickly. This enables the user on the next storey to repeat every single step with a level of safety that comes from performing routine tasks, allowing the work to progress rapidly.
