The Heritage Time Capsule (HTC) project is one of the most ambitious and visionary initiatives ever undertaken by the ISSMGE. As we prepare to seal a physical time capsule in 2026, now is the time to ensure your contribution is included in this historic global record of geotechnical engineering.
What Is the HTC?
The HTC project aims to preserve the legacy and evolution of geotechnical engineering over the last 100 years while setting the stage for the next century. Through the HTC website https://htc.issmge.org members from across the globe have already contributed over 100 pieces, including articles, videos, interviews, and reflections from societies, technical committees, and individuals.
A physical 1m³ capsule, transparent and multi-compartmented, will be sealed at the 21st ICSMGE in Vienna in 2026, not to be opened until 2126.
Final Call for Submissions Until December 2025
We encourage all ISSMGE Member Societies, Technical Committees, Corporate Associates, Past Presidents, Key Persons, and Board-Level Committees to contribute to this unique legacy project. Contributions can be:
-
Personal reflections or interviews
-
Reports and histories of your society or region
-
Technical innovations, lessons learned, or case histories
-
Videos or multimedia material
-
Retrospectives on foundational figures or practices in your area
Even if you have already contributed, updates and additional content are welcome.
Submit your material via the HTC website: https://htc.issmge.org
Become a Discoverer
Alongside contributions, ISSMGE invites individual members to participate as HTC Discoverers, highlighting and reflecting on existing HTC entries. This is part of Phase 2 Discovery, including a £3,000 prize pool in the 2025 Discoverer Report Competition.
This is an opportunity to engage with our profession's heritage, gain visibility, and contribute to shaping its future.
