Anne Kathrine Kalager
Anne Kathrine Kalager has a Master’s Degree in Geology from the University of Oslo. One of her main focus areas, is the preparation for the performance of the projects. Good knowledge of the ground-conditions is always an important key to success.
Since 1989, she has held key positions in the performance of several major railway projects. Tunnels have formed a significant part of all the projects, many of them located within urban areas. The majority of her tunnel-projects have been performed by the Norwegian Method of Tunneling by drill and blast excavation. The extension of the National Theatre station in downtown Oslo, is probably her most spectacular project, with huge technical challenges and limited access in combination with measurements to reduce the impact for the neighbours. The project was successfully finalized after a three year long construction period.
Since 2007, she has hold the position as Project Manager for the 20 km long twin-tube tunnel at the Follo Line project. The tunnels were successfully excavated by four hard-rock TBMs operating from one centrally located access-point. She has followed the project from the beginning, and it will be handed over in 2021
A civil engineer since 1989, Catherine LARIVE obtained a doctorate in mechanics from the Ecole Nationale des Ponts et Chaussées (ENPC) in 1997 on the modelling of structures affected by the alkali-silica reaction and won the ‘Thesis of the year’ prize awarded by the Foundation of the ENPC.
Specialising in concrete and concrete structure pathology, she joined CETU, the French centre for tunnel studies, in 2000 and soon took the head of the Materials, Structures and Durability Department. For 20 years, she participated in several tunnel rehabilitation projects. She has also been and still is involved in many research programmes. For example, she was selected in 2016 for an ITA Award, in the category 'Renovation/Improvement Project of the Year' with an innovative waterproofing system. She also received an award from the French association of civil engineering, AFGC, in 2019.
Her main technical fields are tunnel surveillance, inspection and diagnosis; concrete - especially sprayed concrete; and waterproofing methods. She is now extending her scope of activity from civil engineering to tunnel equipment, safety and operation, as head of research and partnerships, leading the CETU research and professional guidelines programme.
Catherine is the French representative within ITA’s WG 12 on Sprayed Concrete Use and is active in several other national and international committees, working on topics such as standardisation.

Xavier joined Dragages Hong Kong Ltd (subsidiary of BYTP) in January 2014 and the Liantang Road Tunnel Project (twin 2 lanes 4.8Km tunnels / TBM + D&B + Mechanical excavation and Buildings/E&M) till completion in 2019 as Technical Manager.
He also led several Tenders in Hong Kong (IWMF Waste treatment facilities in 2017 (artificial island + process plant buildings), Central Kowloon Route - Central Road Tunnel in 2018 (awarded), and T2 Trunk Road sub-sea tunnel in 2019 (awarded).
He is currently Technical Manager on the Central Kowloon Route – Central Road Tunnel Project (2.8Km twin 3 lanes road tunnel underneath Kowloon, from Yau Ma Tei to Ma Tau Kok, mostly D&B excavation, 7 faults crossings, 7m dia. TBM pilot tunnel).
Chrysothemis is a Tunnel/Mining Engineer (MEng) with post-graduate studies (MSc) in Tunnelling from NTUA (GR).
In 2016, she completed her PhD which involved working in a joint Research Project between Queen’s University and ETH Zurich. In 2017 she was appointed Assistant Professor at the University of Leeds (UK) where in 2019 she got her tenure (permanent chair) in Tunnelling and Rock Engineering. She has been also appointed as visiting Lecturer at Warwick University in the UK and Adjunct Professor at Queen’s University in Canada. Her research deals with Underground Space, innovative design, resilient infrastructure, societal impact. She has published more than 40 papers in international journals and conferences.
She also works as an Independent Private Consultant and in the past as Tunnel Engineer. She is an active member in the British and Greek Tunnelling Society Young Members Group, ITACUS and ITA-CET. She is currently an EMBA candidate at Leeds University Business School.
When Chrysothemis is not working you will find her spending time with friends and family at her Eden a magical place in Southern Greece. In Greek, her first name (Chrysothemis) means Golden (Chryso) Natural Law - Justice (-Themis), in case you were wondering.
