Entrants must submit an original paper relating to any aspect of tunnelling which they consider of interest to the tunnelling industry. Entries close at 17:00 GMT on January 10.

The BTS’s Harding Prize is open to all tunnelling engineers aged 33 or younger at the end of the previous year from the submission date. BTS membership is not a requirement.

The papers will be reviewed by the BTS sub-committee, and authors of selected papers will be invited to make an oral presentation to the BTS meeting on Thursday March 20, 2025.

The winner will receive two tickets for the Society’s annual dinner, held in May 2025, where they will be presented with a certificate. They will also receive £750 and a copy of the BTS’s 50th Anniversary Book.

Finalists whose papers are selected for presentation at the BTS meeting in March will each receive £250 and a single ticket for the annual dinner. All remaining entrants who submitted a paper to an approved standard as determined by the judging panel, will each receive £100.

The papers of the winner and finalists will be published in Tunnels & Tunnelling so images used in the paper need to be of high resolution.

Papers not selected for the final presentation may be published in the ICE Proceedings. The BTS encourages entrants to take up this opportunity to make their work visible to the civil engineering community.

Entries must be submitted by email only to:bts.awards@britishtunnelling.com

Any questions should be submitted to: bts.awards@britishtunnelling.com and Ken Kwok at ken.kwok@bouygues-construction.com

His presentation – The construction of large diameter shafts within challenging ground conditions – detailed dewatering, ground condition and monitoring challenges that had to be overcome via technical innovations, a collaborative approach, and an overall positive mindset.

The Harding Prize is named after the BTS’s founder chairman, Sir Harold Harding.
