Lusail Expressway Microtunnels

temporary and permanent design were required for all shafts

Working with our design partner, ASCO, we produced the conceptual and detailed civil, structural, geotechnical and M&E design associated with the Utility Service Tunnels, Storm Water Tunnels and Foul Sewer Tunnels. The tunnels are to be constructed as part of the 12km Lusail Expressway which will link the heart of Doha with the North of the city. 

This D&B project was awarded to Hyundai Engineering & Construction and consists of 1 km of 1m diameter foul sewer, 5km of combined 3m and 2.4m diameter utility service tunnels and storm water tunnels .

The utility service tunnels and stormwater tunnels require the construction of 15 No large 7.5m diameter permanent shafts, constructed within 11m diameter temporary secant pile shafts.

The scope of works included temporary and permanent design of all shafts, design associated with all tunnel and shaft linings, cable supports, ventilation system , drainage, heat detection,  alarms, lighting, security and low voltage power supply.

Scope of Project

  • The Lusail Expressway Microtunnels will create a strategic free-flow axis of movement connecting the heart of Doha city with its North.
  • Civil, Geotechnical, Structural and M&E design of the micro-tunnels and temporary and permanent shafts as well as the design of internal tunnel and shaft fittings.
  • Undertook hydraulic assessment of connections to  stormwater tunnel and designed associated vortex drop systems and energy dissipaters
  • HAZOP and Operation & Maintenance studies for tunnel systems
