“Engineering is not only about solving problems, but about creating solutions that last.” — Henry Petroski
Post-Tensioning Works at IKN National Mosque in Indonesia Successfully Delivered
This milestone marks the completion of post-tensioning installations for both beams and slabs across key structural areas. The works were delivered through a fully integrated process, from design coordination through to on-site ex*****on, ensuring consistency and precision at every stage.
A key challenge in this project was the implementation of a circular post-tensioned flat slab system, designed to support large, column-free spaces beneath the mosque’s main dome. This required close coordination, precise tendon profiling, and disciplined control throughout the stressing and grouting processes.
Despite the technical complexity and demanding site conditions, the works were carried out in line with the required standards. The completed structure now achieves the intended performance, providing wider spans, and improved structural efficiency.
With this milestone achieved, Utracon is proud to have contributed to one of Indonesia’s landmark developments—delivering not only engineering solutions, but also supporting the creation of a space that will serve the community for years to come.
