Project Overview
In 2024, Glory Track supplied a customized Tunnel Rail System and supporting steel structures for the Jeddah Airport Eastern Tunnel Sewage Carrier Line project in Saudi Arabia.
Located east of Al-Haramain Road and extending to Airport Lift Station 2, the East Jeddah Tunnel Project is a major wastewater infrastructure development with an investment exceeding SAR 774 million (approximately USD 206 million). The 14 km tunnel plays an essential role in improving sewage transportation and supporting wastewater management across more than 10 districts in Jeddah.
For this underground infrastructure project, Glory Track was responsible for supplying the complete rail system and specialized steel accessories required for internal tunnel maintenance operations.
Project Requirements
The tunnel project required a reliable internal transportation and maintenance system capable of operating in a confined underground environment.
The main challenges included:
- Limited installation space inside the 4.12 m diameter EPB tunnel shield
- Complex geological conditions caused by coral limestone formations
- Strict quality requirements from the National Water Company (NWC) and Bureau Veritas (BV)
- The need for precise installation of rails and supporting structures inside segmented concrete tunnel sections
To meet these requirements, Glory Track provided not only rail products but also engineering support and customized design solutions.
Scope of Supply: Complete Tunnel Rail System
Glory Track delivered a comprehensive Tunnel Rail System solution, including:
Steel Rail System
Tunnel Utility Support Components
- Custom-designed cable holders
- Pipe support holders
Maintenance Access Structures
- Walkway platforms
- Walkway support brackets
Customized Steel Accessories
- Track pressure plates
- Related structural steel components
By supplying the complete system from one source, Glory Track helped simplify procurement and ensured compatibility between all components.
Engineering Optimization Through 3D Modeling
Unlike traditional material suppliers, Glory Track provides engineering support to optimize rail system installation before manufacturing.
For this project, our engineering team developed a complete 3D model of the tunnel rail and walkway system according to the customer’s requirements.
3D Simulation and Installation Verification
Before production, the complete system was digitally modeled and installation simulations were performed to identify possible interference issues within the limited tunnel space.
This process helped verify:
- Rail positioning accuracy
- Walkway structure arrangement
- Component compatibility
- Installation feasibility inside the tunnel segments
Adjustable Pressure Plate Design
Based on the simulation results, Glory Track proposed an adjustable track pressure plate design.
This customized solution allowed minor installation adjustments caused by variations in tunnel concrete segments, reducing installation risks and improving construction efficiency.
The client highly appreciated these optimization suggestions, which helped minimize potential delays during on-site installation.
Quality Control and BV Third-Party Inspection
For this critical infrastructure project, all supplied components were manufactured under strict quality control procedures.
The supplied steel rails and fabricated accessories underwent Bureau Veritas (BV) third-party inspection to verify:
- Material quality
- Dimensional accuracy
- Welding performance
- Compliance with project specifications
Through comprehensive inspection and quality management, Glory Track ensured that every component met international infrastructure project requirements.
Customized Manufacturing and Secure Packaging
Tunnel projects often involve complex-shaped steel structures that create challenges during international transportation.
To ensure safe delivery, Glory Track conducted multiple packaging tests and optimized container loading methods before shipment.
The customized packaging solutions provided:
- Better protection against deformation
- Improved container space utilization
- Safer transportation during overseas shipping
All tunnel components arrived at the project site in good condition, ready for installation.
Project Results
The successful delivery of the Jeddah Airport Eastern Tunnel project demonstrated Glory Track’s capability in providing complete Tunnel Rail System solutions for large-scale underground infrastructure.
Key achievements include:
- Smooth on-site installation without technical issues
- Reliable delivery of customized rail and steel structures
- Successful completion according to the project schedule
- Positive feedback from the project team
The completed sewage carrier line now provides long-term support for wastewater transportation and contributes to improved infrastructure development in Jeddah.
