King Abdullah Financial District (KAFD) is a multipurpose business and residential complex located in Riyadh, Saudi Arabia. The district consists of more than 50 towers and should ultimately host a working population of around 12,000 inhabitants.

Dextra Middle-East, also located in Dubai, has been involved from2009 for the supply of several building packages to Saudi Bin Ladin Group, the main contractor on the project.

Foundations piles

In order to provide vertical connection in foundation piles, Dextra supplied through its partners fabricators its popular
Bartec rebar coupler solution, the #1 rebar splicing solution in the Middle East.

As a complement to Bartec couplers, Dextra also supplied Unitec couplers, which were used for the continuation of bars protruding from the foundation piles. Unitec is a flexible solution for contractors as the bar end doesn’t need to be prepared in advance. It only requires an impact wrench and therefore it is easy to operate on remote building sites.

Raft and Columns

Bartec couplers were also used for the horizontal connection in the thick foundation rafts, and vertically in the protruding columns.

Corewall-to-beam applications

In the building superstructure, Dextra Bartec couplers were used to provide horizontal connection from the corewall, allowing to insert the second phase starter bars needed to create the beam reinforcement.

Parque Da Cidade is a multi-tower multi-purpose green building complex located in the south of São Paulo. The project hosts 5 corporate office towers, a hotel, residential buildings and a shopping mall.

For this project, DextraDoBrasildelivered to contractor Odebrecht its Rolltec rebar coupler solution.

Rolltec is the most popular rebar slicing solution in Brazil, providing a competitive alternative to lap splices and more importantly allowingadvanced applications simplifying project management and operations.

For Parque Da Cidade, Rolltec rebar couplers were used to provide a connection between the columns and the beams. The solution was supported by a Rolltec equipment installed at site and maintained by our Dextra local engineers.

For that application, rebar couplers are aligned horizontally in the column reinforcement at each floor and cast in concrete. Dextra provide its couplers with thread protection cap so there is no risk of liquid concrete leaking into the coupler.

At a later stage of the project, continuation bar can be connected directly into the couplers, providing convenient starter bars for the beam or slab reinforcement.

Furthermore, on Parque Da Cidade, Dextra delivered its Unitec solution. Unitec is a bolted coupler that doesn’t require any rebar preparation. It was used on Parque Da Cidade to provide connection between the rebar protruding from two precast elements.
