Qatar Delivers a World-Class Transportation Corridor
The Expressway represents a crucial component of the Public Works Authority Asghal’s contribution to creating an ultramodern society. Upon completion, the Lusail Expressway will provide a vital connection between the country’s showpiece development zone and Qatar’s existing population centers and infrastructure, enabling broader transit, commerce possibilities and enhanced public safety.
The Lusail Expressway is among the largest public works programs in the Middle East and one of the most impressive in terms of scope, complexity and creativity. This program is made all the more challenging by the need to sustain existing transport and traffic along the corridor as the new, modernized sections are put into place. The upgraded corridor will include 5.4 kilometers of four-lane highway in each direction, with multiple side lanes at each of the three major interchanges.
Upon completion, the Lusail Expressway will provide a vital connection...enabling broader transit, commerce possibilities and enhanced public safety.
The expressway will cross two canals, with existing bridges demolished and replaced by new, multi-lane bridges. To keep the canals navigable throughout construction and minimize environmental impact to local flora and fauna, coffer dams are being built to divert the water while a foundation and piers are installed for each of the new bridges. An underground network of microtunnels is incorporated into the overall design, in consideration of environmental issues and resiliency. Some of these microtunnels will enhance stormwater capture and conveyance to the Gulf, while a separate network of service microtunnels are being handed over to the local electricity authority for the installation of high- and medium-voltage transmission cables. Overall, the tunnels and respective cables will support existing transit needs while accommodating for future city growth, providing a lasting solution.
As Supervision Consultant for the Lusail Expressway project, CDM Smith has the crucial and often sensitive responsibility to monitor, measure and adjust the performance of the main contractor and numerous sub-contractors providing specialty services. Procurement has been one of the more challenging aspects of this work, involving immense, custom-crafted road and bridge components sourced from across the globe. One-hundred-meter-high arches, immense hydraulic jacks, and state-of-the-art intelligent transport modules are some of the many extraordinary elements that are almost common place on this unique project.
With the need for diverse technical skills including construction, engineering, safety management, inspection, resident engineering, quality management and more, CDM Smith staff members have gathered from around the globe to support the project.
The CDM Smith team is bringing together experts of different talents and cultures, from over a dozen countries.
