Singapore North–South Corridor (NSC) Construction

CUMIC is proud to supply to Singapore’s North–South Corridor (NSC) Contract N109A, a transformative infrastructure project aimed at enhancing urban mobility and sustainability. It involves the design and construction of an 800-meter dual 3-lane road tunnel between Sin Ming Avenue and Ang Mo Kio Avenue 3. This segment is integral to the 21.5 km NSC, Singapore's first integrated transport corridor, which will feature dedicated bus lanes, cycling trunk routes, and pedestrian paths to serve public bus commuters, active mobility users, and pedestrians.

In this pivotal project, we supplied 1,504 tons of S355JR H-beams, a high-strength structural steel essential for the construction of the tunnel and associated structures. Known for its excellent weldability, machinability, and high tensile strength, S355JR H-beam is ideal for large-scale infrastructure projects that require durability and resilience. Upon completion, the corridor will significantly improve connectivity, reduce travel times, and promote sustainable modes of transport.

Key Attributes of S355JR H-Beams:

· High Yield Strength (≥ 355 MPa): Ensures that structures can withstand significant stress before deforming, making it ideal for heavy-duty applications.

· Robust Tensile Strength (470–630 MPa): Endures substantial pulling forces without failure, which is crucial for components subjected to dynamic loads.

· Adequate Ductility (Elongation ≥ 20%): Exhibits an elongation at break of at least 20%, indicating good ductility. This allows the material to deform under stress without cracking, which is essential for absorbing energy during impacts.

The NSC is expected to be completed in phases, with the viaduct portion targeted for completion in 2027 and the tunnel section anticipated by 2029.
