Following on from the success of the first phase of the project, the latest development will see the creation of 157 luxury housing units, of one to four bedroom Sky Villas, Penthouses, Duplexes and Garden Homes, along with a total internal and external amenity space of 3,000m2 including outdoor and indoor infinity pools.
To support the fast track construction programme, RMD Kwikform has provided design and site support services, in addition to over a thousand tonnes of formwork and shoring for the construction of concrete walls, core walls and slabs. The complex is formed from two residential blocks; Block A has 12 floors and Block B has 10 floors, both of the buildings feature stepped layers and trims as it increases in height. This allows for increased airflow across the development and capitalizes on Al Barari’s existing micro climate, ensuring the continuation of temperatures two to five degrees cooler than other developments in Dubai. To achieve the green credentials and take advantage of the surrounding greenery, Sustainable Builders excavated the basement level of the site, reducing the ground level by 10m.
Due to this level of excavation, RMD Kwikform engineers had to design and supply a range of wall formwork solutions to construct the varying layouts of the 4 to 6 metre high, 400mm thick retaining walls required for the project. Single and double sided Superslim and GTX Beam wallforms were supplied to easily accommodate the varying heights and wall thicknesses required. Traditional gangform comprising Alform and GTX Beams were also used for the construction of the core walls.
For the standard basement slabs, RMD Kwikform’s Prop Tableform system was combined with Rapidshor U-Heads to provide a strip and re-erect system. Although not the traditional use of the system, Prop Tableform was to be used later in the construction, which provided the customer a cost effective solution. In addition, 80kN Rapidshor was used for the beam support.
Moving up the structure, RMD Kwikform also supplied the slab support from level two onwards. This is where the Prop Tableform was reused in conjunction with a new prop head designed to accept Alform Beams – a specific requirement from the customer. For this construction phase, the Tableform Props were assembled into a traditional tableform system, remaining erected throughout construction. This allowed them to be craned into the next floor position using the ‘C’ Hook, allowing the fast pace of construction to be maintained.
Along the roof level of each of the buildings, the structure is designed to have partial 12m-long cantilever slabs that needed to be supported from the second level. For this, RMD Kwikform designed and supplied Alshor Plus towers that reached a height of 34m for one block, and 40m for the other. One of the more challenging aspects of the projects was designing the falsework for each of the cantilever slabs, as it had to start from three different levels and join in one single birdcage to ensure the stability of the temporary structure. For example, to support the cantilever roof in Block A, some of the towers started on the 2nd level, some on the 3rd and some on the 8th floor.
Commenting on the project, RMD Kwikform representative, Dana Cornel said: “Due to the tight timescale for this project, we had to work very closely with the team to coordinate the delivery of the products to match the erection sequences of the design. We also had to be very flexible and responsive to the changes in the programme, ensuring our design team came up with the most cost effective solutions possible, whilst providing all of the drawings in a timely fashion”.
“For example, by combining our Prop Tableform system and Rapidshor on the project, we were able to reduce the programme time and therefore cost of the project. In addition, our design team recognised the opportunity to provide reusable corewall forms for the 11 sets of core walls of the complex, adding to the overall projects sustainable focus”.
“But most importantly, for a project like this, where you have so many operatives on a site, you can’t underestimate the importance of safety and this is why we supported the project with our site assistance team. The team was able to provide coordinated support from branch to site, in addition to erection training and pre-pour safety checks, helping site operatives to meet key project goals safely and on time.”
