Executive Summary
2022 was the year of bringing a period of normality back to the BTS and the industry, which was
grabbed with 8reat delight.
Many projects made significant milestone progress in 2022. including the preparation and launch.
break through and turnaround of a number of TBMS for major projects such as H52 and Silvertown. as
well as key procurement announcements.
Our membership has seen a turnaround in some areas from 2021, Individual membership has not
changed, the fall in young members has been reversed to a healthy increase, the same with
students/retired members, but corporate membership fell. A150, overseas memberships were
constant.
The year saw a full program of BTS and BTSYM evening lectures being held both in person at the ICE
and online via our You-tube channel, although attendance numbers did not return to pre covid, we
feel this was for several reasons.. continuation of the covid working method5, the ICE Bar & the famous
"BTS Sausage & Chips" being not available through 2022 due to staffing shortages and then the refurb.
We have had a good range of topics at the evening events and su5t3ined a high level of or)line
viewing-
The full BTS program of events meant we were able to hold the Annual Dinner, demand for places was
such that we had 807 diner5 at 78 tables. Crowded but everybody enjoyed the return to
normality. The evening followed the established format. champagne reception, fine dinner. then the
address from our Chair Ms Kate Cooksey. Our speaker, the television host steph McGovern, focused

2. Chair's Report
2022 was a fvll year of nomiality after covid. For the tunnelling industry it saw the ramping up of
delivery of major project5 such as HS2, Sifvertown and Lower Thames Crossing and the opening of
Crossrail- The Elizabeth Line-.
The BTS in person events saw a full year's program completed, with the addition of the events
continuin8 to 80 Out on the BTS YouTube channel, a future permanent fixture.
We had the BT5 Conference back at its correct year, myself presenting with E￿at privllege the"David
Wallis Lecture" which I titled - A Past to Be Proud Off, A Future That Looks Green.
It was great to see so many friends and collea8ues coming together and catching up at such a fantastic
event. It was also great to be joined by so many of our international colleagues including the new ITA
President Amold Dix of AustralSa who also presented at the event. The BTS are very grateful to
Tunnelling Joumal for managing such a fantastic event with the BTS.
l am incredibly thankful to all our speakers who continued to embrace the online experience as well as
those that have given evening lectures in person. They have all given their time to come and present
to us and share their knowledge and experience, with many having made an exceptional additional
level of preparation to help make each of our events a success. The wide and varied selection of
evening presentations not only showcases what our industry can do but it also continues to be a
leading light in the knowledge sharin8 activities of the ICE and its Associated Societies.
It 15 fantastic to see people back at our in-person events but also that our online presence and lecture
views 15 remaining high, this I feel is allowing the society to engage with a wider community.

British Tunnelling Society Annual Report and Accounts 2022
The ICE bar and caterlng remaining closed we continued to walk around the corner to Westrninster
Arm5 as an alternative.
The BTYM have continued fostering links to other tunnelling groups around the world. these of course
being done virtually. even taking account of the time zones.
Our membership has seen a turnaround in some areas from 2021, Individual membership has not
changed, the fall in young member has reversed to a healthy increase, the same with students/retired
members, buf corporate membership fell. Also. overseas memberships wa5 constant. The challenge
ahead is to further grow our membership which we hope will be easier to achieve with combination of
in person events and the new virtual arrangements that everybody is now more comfortable with.
We have a150 Continued with our aim to provide information and guidance with our publications,
evening meetin85 and training courses. The work on BTS Specification 4th Edition continues which
should be ready for publication in early 2023. Our SCL Best Practice Guide will now be worked on now
the 4th
Edition 15 completed.
It gave me great delight thi5 year to be able to h05t the Harding Prize after receiving a substantial
number of entries. The prize wis awarded to Christopher Barrett for his paper Yhe planning and
construction of mainline tunnel B connection tunnel..
Plans for the Soth Anniversary Book continue at pace and a sample book chapter and example size
book were made available to be viewed at the BTS Conference- it is rather overwhelming to see the
amount of stories there are to be shared, this has resulted in its publication being delayed into 2023 to
incorporate all the stories we have to shère. The monthly pie chart updates have shown the amount of
ta5k5 that are need for its completion. Please ensure that you have a space ready on your coffee table.
The BTS Young Members, group continues to grow and continued to embrace delivery of online
lecture5. They celebrated National Tunnelling Davl World Tunnel Day. further developing our
international links. Holding evening meeting and workshops through the year.
They have focused on social media campaigns and events to continue to support the youn8er
members of the tunnelling industry.
The James Clark Medal 2022 was awarded to Ken Spiby, the award was made in recognition of his
services to the tunnelling industry through recording the past 50 years of activity of the BTS and the
wider tunnelling industry in the"BTS at 50" book.
We had two James Clark Medal Winners luncheons 2022, (February and October) to make up for the
cancellation5 in 2020 and 2021. It was great to see the return of some winners we had missed catching
up with at past luncheons.
The Ooug Allenby Award was established in 2020 and the funds are to be used to award a medal to a
young tunneller IBTSYMI annually in Doug's Memory. The I" award was made at the James Clark
Medal Winne<s Lunch on 20 October 2022 to Ignacio Tognaccini-sainz.
The Thames Tideway Project has its last machine in the ground and is progre55ing with secolldary
lining and civils Structures. York Potash has been busy tunnelling and shaft sinking and several of the
machines have successfully launched on the H52 London to Birmingham route. The launch of the TBM
for the 5ifvertown Tunnels occurred.
Work on numerous smaller tunnels also occurred, these both on the malor projects like HS2, in the
form of 1200m & 1500mm Micro Tunnelling to facilitate utility diversion5, also for the UK Water, Gas
and Electric organisations for the installation of new assets. Part of the industry that we should not
for8et about. a sector of the industry that needs bringing to the fore.
I would like to thank all the committee for all their support and effort during my year as Chair, the
committee ha5 remained active at all times in progressing the ambitions of the society and l am
incredibly grdteful for the positivity in approach, as well as all the spare time the committee

3. BTS Objectives and Communications
Alostoirsmitlj Ichairj. Kate C1￿kSeY. Jerome Ftsrge. Mehdi Hosseini, Tim Smart. George Doulkos, Ken
Spiby. Shani Wullis, Patrick Reynolds, Ayo Husson.
Communication in 2022 saw the January and February meeting5 continuè online only with the lecture5
streamed live on YouTube. From March 2022 the lectures returned to hybrid in person with Iwe
Streaming. The live streaming remained popular and preferred by many members partly due to
concerns over Covid and the fact that the ICE bar and catering facilities remained closed for the
duration of 2022.
Emails, both to individual and corporate member5 are the primary method of communication and the
effort5 by Katherine Coldwell are recognised and greatly appreciated by the society. For the sotial
media ihe BTS operated on the Twitter. Facebook, Linkedln and Wikipedia platforms Wlth the BTYSM
running accounts on Facebook, Twitter. Linkedln and Instagram.
Adverts published monthly in Tunnels and Tunnelling International have continued to be part of the
Communications strategy and have been focused each month on publicising upcoming events. The
subcommittee appreciates the work by Divik 8andopadhyaya in preparing the adverts each month.
YouTube continues as the platform for delivery of the online evening lectures both for online only and
hybrid, with the committee meetin85 both online only and hybrid facilitated using Microsoft Teams.

The Communications Sub Committee has established a storage platfomi for the countless ima8es and
photographs that have been collected for the 50, Anniversary Book.
Following a personal visit by Kate Cooksey to the National Railway Museum INRMI in YoTk an
opportunity for enhancing ￿rne of the Tunnel related exhibits was tabled at the committee meetinB
in November 2021. The Communications Sub Committee subsequently reached out to the NRM to see
if the BTS could provide any assistance. This proved opportune and p051tive and aligned with the NRM
plan for a major redevelopment of the museum site as part of their Vision 2025 strategy. An initial
meeting with the Museum Curator. Andrew McLean and BTS Committee members Rod Young and
nd
Alastair Smith was held at the museum on 2 September 2022. Following thi5 meeting a BTS / NRM
workin8 8roup was established to follow up on the collaboration opportunities both for the museum

and the option of holding reglonal events at the NRM in the future. The Workin8 group is Alastair
Smith, Rod Young, Kate Cook5ey, Tim Smart and Aya Hasan.
Thank you again to the Communicationssub-committee members for efforts in 2022.
4. Finance and Membership
This year it wa5 agreed to retain the current individual membership fee for a further year, in refleclion
of the current economic climate and the cost-of-living challenges. A modest increase of 5% has been
added for the corporate membership fees.
The rnembership fee for 2022 again included the provision of a hard copy and digital version of
Tunnels and Tunnelling magazine. An agreement had been signed between BTS and T&TI for 5 years
in 2020 (with a 3-year break clause) and a reduced contributlon from BTS to the magazine. This
provides stability and value for money for a significant period.

Overall cash reserves have remained relatively stable at £460,08312021- £465,584). It is expected
that the majority of the BTS at 50 book costs will be spent in 2023 with a worst-case overall cost1055
of £50.0(J). It 15 felt that the le8acy of the book, even with this potential lo55, remains an extremely
worthwhile outlay for the members. Most of the sponsorship for the book has now been receNed and
is included in the above figures. Net current assets increased from £318.410 to £364,491 at the end of
2022.

The All-Party Parliamentary Group for Infrastructure IAPPGII is run jointly by the ICE and the BTS,
having merged the BTS'S APPG on Underground Space IAPGUS) several years ago in order to focus
Parliamentarian5 on fewer overlapping All-Party groups.
This enables BTS to concentrate on site visits and projects and initiatives of interest to its members
and parliamentarlans whilst leaving the administration of the Group and broader ICE policy aims to

The stated aim of the group 15 to 'highlight the importance of infrastructure, engineering and the use
of underground space to the economy and society, and to hear from experts and dixuss matters

The BTS celebrated its 50th Anniversary in March 2021, but the Covid pandemic meant that this was
much more muted celebration than had been hoped.
A book: 'Tunnelling Tales: Fifty years of the British Tunnelling Society" is under production, but we
were unable to complete thls In time to publish in 2021 for the attual anniversary. or even in 2022, It
is very much hoped that we can publish in 2023. This will mean that the book will be 2 to 2.5 years
late. The main reasons for this are..
The book has proven to be much more popular than anticipated and will be around 4 times the
slze of the original proposal
The volunteers in the main, have full-time day jobs and can only commit a Ilmlted amount of time
to the book
None of the volunteers has published a book befo￿. and all severely underestimated both the

Annual Dinner

tld
The SOCIe￿s 32 annual dinner was held at The Brewery banqueting centre in London on Friday 6,
May 2022. This was the first dinner after a two year break owing to the Covid pandemic. As
Lockdown hit after a considerable number of bookings had been tsken for the 2020 dinner, we offered
free bottle of wine to every table that stood by their 2020 booking. A total of 35 bottles of 'farewell
to lockdown, wine was provided to reward those members that retained their 2019 bookings to thank
those members.
Demand for places was such that we were unable to keep to our target of 75 tables, accommodating
807 diner5 at 78 tables, of which 26 were tables of 11 people. This did make the room feel a little
crowded in places. For the 2023 dinner, we will not exceed 75 tables of 10 people.
The evening followed the established format and was thus preceded by a champagne reception.
After the usual fine dinner, we were treated to a rousing address from the Chair Ms Kate Cooksey,. this
was her second year as BTS Chair, but due to the hiatLJS of the pandemic, her first dinner in that role.
The theme of women in engineering was maintained by our speaker, the television host Steph
McGovern, although her address focused more on hef recent career activities. On conclusion she
acceded to a request from MC John Scholey to a brief display of Irish step dancing to the reel
'Mountain Road, to some great acclaim.
Profits from the dinner go to support the BTS learned society activities. We are particularly grateful to
Jacobs. our prime sponsor, whose support has enabled us to increase this contribution.
There was again a roving photographer; thi5 year, those attendin8 were given free access to download
the resulting images.

The BTS continues to have a close relationship with ICE. As one of the largest and most active of the
ICE'S Assoclated Societies the BTS is a signlficant User and beneficiary of ICE facilities including meeting
rooms, lecture theatres, bar and restaurant, and secretariat 5UPPOrt. The arrangement 15 via a Service
Level Agreement whith continues to be reviewed annually.
A change in the financing arrangements in 2018 encouraged us to ftjcus more on technical project5 and
to seek funding assistance from the ICE Enabling Fund, and this 15 Still the case.
The ICE re8ularly refers tunnel-related media querles to BTS committee members and relies on our
advice and expertise in such matters. These referrals have resulted in senior BTS members appearing
on TV, on radio and reported in the national. local and technical press.
The BTS and the ICE continue to jointly run the All-Party Parliamentary Group for Infrastructure.
