Residential construction in Abu Dhabi
MEVA offers flexible formwork solutions for all areas of construction
High-quality concrete finishes
A new residential building is coming into being in Abu Dhabi with a floor area of 2,500 m². The multifaceted construction of the building shell is being performed using MEVA formwork systems.
The new building consists of two basements and eight upper storeys. Upon completion, the ground floor will house, among other things, a sports centre and numerous shops. New living space is being created on the floors above.
In the construction pit it was first of all necessary to pour outer walls against the existing structure. As conventional anchoring was not possible, the STB 300 support frame was used as a single-sided solution. Thanks to the STB 300’s anchoring system, the tensile and compressive forces are safety transferred into the floor plate. Mammut 350 was used for the formwork. The wall formwork with panel sizes up to 3.50 m x 2.50 m comprehensively covers the need for large-area formwork.
High-quality concrete finishes
In addition, more stringent requirements applied to the architectural concrete quality in the basements, as the concrete surfaces in this area were to remain visible. The Mammut 350 wall formwork is equipped with alkus all-plastic facings. The innovative facing ensures consistently smooth, high-quality concrete surfaces, does not absorb water, and does not swell or shrink. The facing is just as durable as the frame, thus saving the necessity of expensive replacement. Furthermore, it is can be nailed just like wood and repaired using the same material.
MevaDec flexibly adapted
“A particular challenge was the slab formwork in the basement,” said MEVA’s Ahmed Atalla, who is responsible for the construction site on the spot. “The height of the slab varies. At the same time, the thickness of the concrete beams also varies.” For this reason, the MEVA engineers made use of two different formwork systems: MevaDec for flat slab areas and conventional slab formwork for the varying concrete beams. It was possible to use MevaDec between the concrete beams without large compensation areas as the system can be adapted to suit the specified dimensions by changing the direction of the primary beams. Moreover, construction progressed rapidly thanks to the use of the MevaDec drop head in the flat slab areas. Activating the drop head lowers the primary and secondary beams of the slab formwork by 19 cm so that these can be easily removed and used for the next pouring cycle. During this time, the props remain in place and support the slab until the concrete has set completely. Being able to reuse the slab formwork panels earlier enables the material stock on the construction site to be optimised.
Focus on customer satisfaction
The concrete beams were formed conventionally because of their massive geometry and great weight. For this project the decision was made to use aluminium beams, which can support a higher load than wooden beams. Thanks to this solution and the use of MevaDec, plywood was only used for the facings of the concrete beams. “This approach meant that we were able to save plywood over large areas and thus reduce costs,” Ahmed Atalla was happy to report. “After all, in our role as formwork experts it is our task to advise the customer and provide safe, efficient and, last but not least, sustainable solutions.”
