This is the most important international annual event in the field of tunnels and underground works, organised by the ITA-AITES International Tunnel Association, with the collaboration, on this occasion, of the Swedish Rock Engineering Association as an entity representing the host country. The congress brings together professionals from the industry of tunnel construction and underground works, including engineers, manufacturers, suppliers and experts in this field, to discuss the latest advances, share knowledge and promote the latest techniques and technologies.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559738&quot;:0,&quot;335559739&quot;:120,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">In this edition, the congress brought together more than 3,000 specialists and professionals from all over the world, consolidating itself as the reference platform for the exchange of knowledge and innovation in underground engineering.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559738&quot;:0,&quot;335559739&quot;:120,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">TYPSA&#8217;s presence at this event was of great importance, reaffirming its commitment to technical excellence, sustainability and digitalisation as key drivers for underground infrastructures in the future. The corporate stand in the exhibition area was a meeting point for clients, partners and professionals in the sector, where our global capabilities in tunnel projects were presented and new opportunities for international collaboration were explored.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559738&quot;:0,&quot;335559739&quot;:120,&quot;335559740&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">The company&#8217;s important role in tunnel projects, both in Scandinavia and in other regions of the world was showcased. Among the most significant projects in the area, TYPSA has participated in the preliminary and detailed design of the Stockholm metro blue line, currently carrying out this same work for the expansion of the yellow line, in the development of the Moss station, in the modernisation of the railway network in Viken County in Norway, and in the Sotra project, also in Norway.<\/span><span
