PROJECT APPLICATION
KUWAIT’S FIRST IN-SITU
CANTILEVER BRIDGE An all-in-one formwork solution was provided for the project.
Nawaseeb Road is an important element of Kuwait's transport infrastructure. The bridge project is a special case for two reasons: Not only is it currently Kuwait's first cantilever bridge project, but it is also the first time a bridge is cast in-situ.
The Nawaseeb Road in Kuwait forms an important part of the country’s national infrastructure, providing a strategic, logistical corridor to neighbouring Saudi Arabia. In delivering a solution for the highway bridge section, Doka has helped provide Kuwait with a landmark achievement - its first, in-situ cantilever bridge. Doka is a world leader in providing innovative formwork, solutions and services in all areas of construction. The company supplied an all-in-one solution, which included 3D planning, Cantilever Forming Travellers (CFTs), and formwork instructors’ support to ensure a smooth, fast and cost-effective process. Section RA217 of Nawaseeb Road, also known as Route 40, is one of Kuwait's most important infrastructure and transport projects and is part of the Kuwait Development Plan 2015-2020. Covering a stretch of 37 km, the development includes the reconstruction and expansion of the highway into a six-lane dual carriageway (three in each direction) with nine interchanges and three bridges, with the ultimate aim of improving access and safety on the roads, by eliminating U-turns and replacing them with roundabouts at all interchanges. Doka was required to find a casting solution for the two main bridges, including pier-to-pier spans, which at their longest measures 110 m each and has a total combined length of 940 m, as well as one ramp bridge with a maximum span of 95 m between piers and measuring 893 m in length. A total of 300 casting sections, weighing up to 250 tons, were required for the project. 34
THE SINGAPORE ENGINEER May 2021
The Doka Cantilever Forming Traveller offers formwork and shoring from a single source. The ideal balance between support structure and formwork enables the construction of 470 m of the main bridge.
All-in-one solution Doka used its internal, digital planning tools to design the right solution for the project, which included detailed designs that helped accelerate the planning process, while providing the client with an overall visual representation of the project. In addition, a 3D model was developed with DokaCAD for Revit to give more precise visualisation of the CFT system. In total, six Doka CFTs, supplemented with approximately 2,000 m² of Large-area formwork Top 50 were used on both the main bridges and ramp bridge at Interchange
