The Marina Coastal Expressway Tunnel, completed in 2013, is a landmark project that stretches over 5.2 kilometers, providing critical connectivity for traffic flow in Singapore. This project involved extensive underground excavation and the installation of utility corridors accommodating water, gas, and electricity pipelines. The successful integration of advanced tunneling techniques with robust project management resulted in a 20% reduction in construction time compared to traditional methods, showcasing our ability to innovate under pressure.

The KPE extension, which opened in 2020, spans 3.5 kilometers and is designed to improve capacity for a growing urban population. Throughout this project, we coordinated the installation of a multi-utility corridor that houses critical services for the area, accommodating both existing and future utility requirements. Our meticulous planning and execution led to a significant 30% decrease in utility relocation costs compared to previous projects, reaffirming our status as a leader in the underground utility sector.

The North-South Corridor represents Singapore's first integrated bus and bike corridor, featuring a 21-kilometer stretch that runs beneath existing urban infrastructure. Launched in 2022, our team successfully implemented this ambitious project, which required the deployment of advanced tunneling technologies and effective risk management strategies. With a projected capacity to carry over 150,000 commuters daily, this project epitomizes sustainable urban mobility and reflects our commitment to enhancing public transport solutions in the city.

In 2021, we undertook the development of an extensive network of underground utility tunnels within the Jurong Lake District, strategically designed to support future development plans. Covering approximately 4 kilometers, this project involved collaboration with multiple stakeholders to ensure seamless integration of water, electricity, and telecommunications services. Our innovative design not only reduced the surface footprint but also enhanced resilience against flooding in the area, leading to a 40% improvement in service reliability for local residents.

The East Coast Parkway Utility Diversion project, completed in early 2023, involved the rerouting of critical utilities to facilitate road improvements. Spanning 2 kilometers, this project was executed under challenging conditions, requiring advanced trenchless technology to minimize disruption. Our team's expertise ensured that the diversion was completed two months ahead of schedule, significantly reducing traffic disruption and earning commendation from local authorities for our efficient execution and problem-solving capabilities.
