Duba ISCC Green Power Plant 1 is a large power infrastructure project taking place in the North West of Saudi Arabia, on the Red Sea. The project, based on the ISCC technology (Integretad Solar Combined Cycle) is a combined Gas (500 MW) and Solar (additional 50MW) power generation plant.

For Duba Green Power Plant, Dextra supplied its Geotec Double Corrosion Protection (DCP) Permanent Steel ground anchors to prevent soil movement in the perimeter of the excavation.

For this project, Dextra provided a “factory grouting” service, meaning that the anchors arrived at the site as pre-grouted 12-meters segments, ready to re-connect via couplers and to install.

Le projet Viaducto del Manglar est un projet de pont de 5,3 km enjambant la Ciénaga de la Virgen (marais), au nord de la ville de Carthagène, en Colombie. Le projet vise à réduire les embouteillages à la sortie de la ville dans la Zona Norte (zone nord).

For this project, Dextra supplied its Headed Bar systems, used into large prefabricated caissons, in order to reduce the reinforcement congestion. That application allow designers to lower the steel/concrete ratio in eleemnts. Headed Bars are also much easier to install, as they fit on straight bar that can be inserted in the case easily.

Louvre Abu Dhabi museum opened its door on the 11th of November! For that landmark project in the UAE, Dextra supplied between 2013 and 2014 more than 110,000 Bartec connections , easing the reinforcement connection for raft and columns, and allowing the creation of temporary openings for the passage of men and equipment.

The Bar-Boljare Highway is a key infrastructure project in Montenegro led by the Ministry of Transportation and Maritime Affairs and built by China Road and Bridge Corporation (CRBC). The 2×2 lanes highway spans over 40km, in seismic environment.

iNGEROP, the consulting firm on the project, required the rebar couplers to comply with ISO 15835 requirements (cyclic requirements as per class S2). For that reason, CRBC chose Dextra Bartec® solution for reinforcement connection.

Four large diameter soft eyes have been installed in the diaphragm wall cages of the new Singapore MRT Marine Terrace Station during August 2017.

Les Soft-Eyes sont fabriqués à partir de barres d'armature en PRV, qui sont utilisées pour remplacer le renfort en acier dans les murs en D des puits de construction. Lorsque le tunnelier (TBM) perce les murs en D, il coupe facilement les barres GFRP, ce qui permet d'économiser du temps sur le calendrier du projet et de l'argent sur l'utilisation de l'équipement.

Dextra a été le pionnier de cette application depuis sa première utilisation dans le projet du métro de Bangkok en 1998 et possède une vaste expérience dans la conception et la fabrication en interne de Soft-Eyes.

The D-Walls installed on Terrace Station also feature Bartec® rebar couplers, a common application which allows for the horizontal re-connection of the station slabs.

Marine Tie Rod solutions can seem at start overwhelming at first as there are many many types of quay walls, anchorage types and ways to connect them with tie rods.

To guide designers through the creation of the perfect quay structure, Dextra has developped a comprehensive step-by-step palette of AutoCAD tool to be used in complement of our Marine Tie Rods Technical Guide. This new tool features our complete range of diameters, grades and accessories.

We hope that this new AutoCAD tool will speed up both understanding of our systems and the design of your structure. For all questions, Dextra Bar Systems dedicated engineering team remains available to support you in the system selection and drawing.
