Dear Esteemed Colleagues and Partners,

‍

On behalf of the International Tunnelling and Underground Space Association (ITA -AITES), the Portuguese Tunnelling and Underground Space Commission (CPT) and the Portuguese Geotechnical Society (SPG) are pleased to invite you to support and participate in the prestigious event ITA TUNNELLING AWARDS 2026, which will be held at the SUD HALL Lisbon, from 4 to 6 November 2026.

‍

The first day will be dedicated to the ITA Tunnelling Awards and on the second day an International Conference on Tunneling, with the title “Contribution of Underground Works to Society”, will be held to celebrate the CPT 20^th Anniversary. On the third day, a series of technical visits of great interest to the participants will be organized, as several large-scale works are underway in Portugal, such as new lines of the subways of Lisbon and Porto, the project of the Lisbon Drainage Plan, hydroelectric works, among others.

‍

This event will provide an excellent opportunity to reflect on the contribution of underground works to society, including their benefits in terms of sustainability, safety and environmental impact, as well as their role in reducing transport emissions and freeing up urban surface for public use.

‍

Hosting the ITA Tunnelling Awards 2026 in Portugal represents a unique opportunity, as it coincides with the 20th anniversary of CPT. We plan to celebrate this milestone with an International Conference bringing together both the global and national tunnelling communities, all within the distinctive setting of charming SUD Hall Lisbon.

‍

The Portuguese Tunnelling and Underground Space Commission (CPT) is fully supported by the Portuguese Geotechnical Society (SPG) which was created in 1951. The event will have the support of AICEP – the Portuguese Trade & Investment Agency, the Lisbon City Council and Order of Portuguese Engineers and the EUTF, The European Underground and Tunnel Forum, among others.

‍

The organization will also benefit the support of key stakeholders in the sector, including major municipalities such as Lisbon and Porto, companies operating in the market (both owners and concessionaires), designers, consultants, engineers and contractors and leading laboratories such as the LNEC. In Portugal, several high-value underground projects will be invited and encouraged to submit applications for the awards, further enhancing the value and appeal of the event.

As a sponsor at ITA Tunnelling Awards & CPT 20th Anniversary International Conference, your company will have the opportunity to connect with key stakeholders and industry leaders, fostering meaningful engagement within the tunnelling and underground construction sectors.

‍

Your support will significantly contribute to the success and visibility of the event. Sponsors will benefit from exclusive access to networking events, including the Gala Dinner and receptions, providing an ideal setting to build new partnerships and strengthen existing collaborations.

‍

The conference will feature an accessible exhibition area showing innovative technologies and solutions, creating a dynamic environment for networking, learning, and the exchange of ideas. We are committed to providing sponsors and exhibitors with an optimal setting for collaboration and connection across Europe and the World.
