Construction in record time with T-60 Shoring Towers: Lusail Boulevard Tunnel, Qatar

Aug 30, 2017
This project consists of the construction of a cut-and-cover road-rail tunnel, including the mechanical systems and services necessary for the A3 Expressway. The tunnel stretches 655 m in length, and is 45 m wide with three separate tubes. The central tube is dedicated to rail traffic, with two lines running in each direction. The project required 300,000 m³ of concrete.

The ULMA & DELMON team provisioned formwork for the walls and slabs of the central tube, measuring 20 m in width, as well as the lateral tubes, each of which are 13 m wide. The walls are 2 m thick at the base, and thin to 1 m at the highest point of 13 m. The ceiling slab, 1.8 m thick, was built to be straight though slightly inclined, throughout almost the entire length of the tunnel.

With our client’s requirements at the forefront, the solution that provided savings in the set-up and take-down for every pour. This is what made the difference in the customer’s choice of ULMA & DELMON for their project, and the final results were no less rewarding than initially promised.
