In the case of the Carlberg Tunnel (Moss, Norway), the width evolves from 13.80 m to 20.65 m along its length, creating a continuous conical transition. This type of geometry requires rethinking traditional formwork approaches: if the tunnel changes, the formwork must change with it.<\/p>\n<p>For this project, a\u00a0<strong>variable and adjustable formwork system<\/strong>\u00a0was used, capable of adapting progressively at each stage. The lining was executed in\u00a0<strong>78 advances<\/strong>, each one different, using modular elements that allowed\u00a0<strong>geometrical continuity and precise shaping<\/strong>\u00a0throughout the transition.<\/p>\n<p>This approach is especially relevant for projects that involve:<\/p>\n<ul>\n<li><strong>Non-constant or evolving cross-sections<\/strong><\/li>\n<li>The need for\u00a0<strong>tight geometric control<\/strong>\u00a0of the final lining<\/li>\n<li><strong>Optimized construction cycles<\/strong>\u00a0without compromising quality<\/li>\n<\/ul>\n<p>In other words: when the structure cannot adapt to the formwork, the formwork must adapt to the structure.<\/p>\n<p>If you are planning or designing a tunnel with variable geometry, you may find the full technical description useful.
