ISSMGE TIME CAPSULE 2026 - STAGED CALL NO. 1

The 100-year time capsule, initiated and sponsored by the ISSMGE Board (2022 - 2026), is an important legacy of the geotechnical community. In November 2024, the Board approved the issue of a number of staged calls to improve receipt of diversity of materials to be considered for preserving in the physical time capsule, and, help improve the allocation of space to various materials within a 1 m3 time capsule that is transparent, with a number of compartments. These staged calls are firstly for published material, printed on paper, secondly, for physical objects, particularly material considered to be of significance to the development of geotechnical engineering, and lastly, for other material. Potential donors** are members of the ISSMGE cohorts of Member Societies, Technical Committees, Corporate Associates, Past Presidents, Key Persons, Vice Presidents, and Board Level Committees. Others interested in donating material can convey their proposal through and with the support of a member of the above ISSMGE cohorts.

Staged Call No 1, open till June 2025, is for potential donors to submit their proposals for published material printed on paper, on,

Regional basis, including geotechnical conditions of Earth’s cities and key environs, and, that of other planets,
Technical basis, including geo education, research, design, construction, ground models, monitoring, preservation, failures, key developments, textbooks, and topical issues like alternative materials, new developments in geotechnical engineering, and other, and,
Philosophy in geotechnical engineering, including autobiographies and biographies of key persons.

Responses to Staged Call No. 1 are to be made on a prescribed HTC form, accessible from about mid - January 2025 on the HTC website, https://htc.issmge.org/. A selection panel led by the HTC Physical Time Capsule subcommittee (https://htc.issmge.org/what-is-htc) will develop applicable criteria and rank submissions to help the ISSMGE Board decide on material to be placed in the physical time capsule.

Potential donors whose proposed published material has been accepted by the ISSMGE Board for inclusion in the physical time capsule will be contacted, possibly towards the latter part of 2025, by the ISSMGE Secretariat, [email protected]. No physical material should be forwarded to the ISSMGE until notified in writing by the ISSMGE Secretariat with instructions as to when and where the material is to be forwarded to.

**Potential donors are to make available to the ISSMGE the published material if selected by the ISSMGE Board, and no payment is to be made by either party. ISSMGE can meet the costs of transport of the selected published material(s) to Vienna, Austria, if requested and agreed.
