Cairo Monorail Bowstring Bridge, Egypt

The Cairo Monorail Bowstring Bridge project, a pivotal part of Egypt’s expanding urban infrastructure, has significantly benefited from the expertise and quality products supplied by Dextra. Known for their innovative engineering solutions, Dextra provided critical materials to support the construction of this state-of-the-art transportation link.

In particular, Dextra supplied tension rods in two distinct specifications for the project:

M78/OD75 in Grade CS520 – A total of 60 sets were delivered.

M83/OD80 in Grade CS520 – An additional 8 sets were provided.

These tension rods were specifically used as hangers for the bowstring bridge, ensuring a high level of strength and durability, which is crucial for the safety and longevity of the bridge, to maintain structural integrity and withstand the stresses of daily monorail operations.

Dextra’s tension rods, known for their high tensile strength and resistance to environmental factors while providing architectural pleasure, played a critical role in meeting these demands. This involvement underscores the importance of reliable and advanced engineering solutions in modern infrastructure projects, highlighting Dextra’s commitment to excellence and innovation in the field of civil engineering.

Cross Island Line (CRL) MRT, Singapore

Dextra has played a pivotal role in the construction of Singapore’s Cross Island Line (CRL) MRT project, supplying Glass Fiber Reinforced Polymer (GFRP) soft-eyes, Bartec couplers and Headed Bars for several crucial packages. Dextra continues to support the ongoing packages of this extensive project.

The CRL is set to become Singapore’s eighth MRT line and its longest fully underground line, stretching over 50 kilometers. The project is being executed in three phases, with the first phase anticipated to be operational by 2030.

To minimize the environmental impact on the forested areas of the nature reserve, engineering solutions were meticulously chosen to further mitigate environmental disruption. These solutions include digging deeper into the ground and employing a large diameter boring machine, capable of accommodating two train tracks within a single tunnel. This approach not only reduces the surface footprint but also enhances the efficiency of the tunneling process.

Tunnel Boring Machines (TBMs) are a staple in Singapore’s subterranean infrastructure projects, adept at operating under a variety of ground conditions. The use of GFRP soft-eyes supplied by Dextra is integral to these operations. Soft-eyes are essential components in TBM tunneling, acting as temporary openings that allow the TBM to break through concrete walls without compromising structural integrity. The GFRP material is preferred for its high strength-to-weight ratio, corrosion resistance, and ease of installation, ensuring safe and efficient tunneling operations.

Dextra‘s expertise and reliable supply of GFRP soft-eyes, Bartec couplers and headed bars have significantly contributed to the progress of the CRL project, aligning with Singapore’s commitment to sustainable and innovative infrastructure development. As the CRL project advances, Dextra remains a key partner, supporting the construction of this monumental MRT line that will eventually enhance the daily commute for millions of Singaporeans.
