The project comprises onshore facilities, a 27 kilometer causeway as well as a beautiful elevated bridge with a 200 meter wide and 23 meter tall passage. When finished, the bridge will reduce the distance between Kuwait City and the Subiyah region from 104 to 36 km, thus reducing the transport time from 90 to 30 minutes. The bridge is one of the biggest and most challenging transport and infrastructure projects in Kuwait and will be a monument to the late emir.
Salt water, high temperatures and increased CO2 levels in the air accelerate the breakdown of the concrete structures significantly. Innovative solutions are therefore needed to ensure that the reinforced concrete has a service life of more than 120 years, as requested by the project owner.
The project is carried out as a Design-Build-Operate (DBO) project, where the contractor must pay the maintenance costs for a part of the operating period. Therefore, there has been special focus on finding a solution that is financially sustainable throughout the entire lifetime of the bridge.
"We're very pleased that some of the world's leading contractors and advisers have chosen Formtex due to the high quality, flexibility and mouldability of the Formtex CPF Liner. This means that the concrete achieves the best durability, while at the same time minimising maintenance," says Michael Møller, product manager at Fibertex Nonwovens.
Fibertex Nonwovens is supplying a total of 1.5 million square meters of Formtex for use in the casting of both bridge pillars and bridge spans. Formtex is used for the casting of the actual concrete elements. The Formtex CPF Liner drains water from the structures and thereby reduces the water/cement (w/c) ratio of the concrete. The result is a smooth and even surface of the concrete elements without blowholes. This ensures a strong concrete surface that is able to withstand impacts from sand and salt water.
It is not the first time that Formtex is chosen for a major international construction project, but it is, however, by far the largest project for the present.
"We've spent a lot of time in Kuwait consulting, testing and not least training the contractor in the application of Formtex in practice. Documented results and the high service level have proved that Formtex is the best solution in direct competition with other solutions and other suppliers," says Møller. Fibertex Nonwovens qualified Formtex® for a construction project as large as the bridge in Kuwait on the basis of numerous reference projects and solid documentation.
"Without a doubt Formtex was chosen for the project because it proved its ability to ensures prime concrete quality in the various laboratory tests carried out prior to construction. In addition, Fibertex Nonwovens is known to supply products of high and uniform quality which we can document in an efficient quality assurance system," says Møller.
The Danish company has worked for more than a decade to be qualified for the project which is now a reality. Following fierce competition with other two candidates, Fibertex Nonwovens won the assignment and the order.
