Design of multi-span segmental concrete box girder viaduct, Works include all structural, highway, marine, M&E and landscaping works, Site representation throughout the design
Ministry of Public Works, Kuwait
Tony Gee was awarded the design contract for the proposed Doha Link, and is responsible for the delivery of all aspects of the design, including structural, highway, marine, M&E and landscaping works.
The marine viaduct is 7.7km long; has three traffic and one emergency lane, in each direction. Onshore works include the design of two major interchanges and an additional 4km of highway, including secondary structures. The Doha link bridge connects with the $2.6bn Subiya Causeway project.
A tight construction period for the works meant that it was necessary for the engineering solutions for the bridge to be tailored to achieve the programme and ease of constructability. From the outset it was identified that the Full Span Launching Method (FSLM) would be the optimum construction method for the project as it is the fastest way to construct long stretches of viaduct. A complete span is precast and prestressed and then transported to the construction work front and launched into place.
Key to the success of the project was the formation of a clear vision for the solution, and in particular the construction methodology, from the very early stages. This focus created a standardised, optimised and visually elegant solution for the Marine Viaduct, accounting for all stages of construction and ease of buildability. On site, meticulous detailed planning by the Contractor and attention to detail in all aspects has enabled the works to be constructed efficiently with high production rates achieved, whilst delivering a high-quality solution. A special working partnership was formed between the engineering organisations involved in the project which ultimately benefitted the implementation and delivery of the structure.
The successful delivery has received positive internal and external praise and it is hoped that the project may create a new benchmark for major highway infrastructure projects in Kuwait in the future.
