Council members

TSA is governed by an elected Council comprising twelve member companies. The Council is subdivided into four core committees: Public Relations (PR), Membership & Internal Affairs (MIA), Technical and Finance.

Claire Fenwick

Spatial Dimensions Ltd


After University I decided to retrain as a Geomatics Surveyor and went on to complete the TSA Surveying Course in 2006. Specialising in measured building surveys and 3D models, I founded Spatial Dimensions in 2012.

I have since won several awards and done a great deal to promote surveying as a desirable profession and encourage more women to join.

I am now privileged to be involved with TSA as President. I am a great believer in the benefits of sharing knowledge and upholding standards and this forms part of TSA’s role as a trade association in the ever changing world of Geomatics. I hope to contribute and have a positive impact with this, helping TSA, other companies and individuals to attain standards set and mark the way for whatever the future technology holds for us.

Nick Spenceley

Catsurveys Ltd

MIA Committee Chair

Having joined Catsurveys Ltd in 2013 which was my first engagement within the geospatial environment, it has been truly enlightening in understanding the profession and witness the professionalism of the community through our TSA Membership.

My passion for the Health, Safety & Wellbeing along with responsible business practices I would like the opportunity to embrace and share experiences of the TSA members.

I commit to promoting TSA membership and engaging with existing members to ensure that that the services and benefits offered are being realised, and the geospatial profession is credited for its outstanding services to industry.

Sam Roberts

Met Geo Environmental Ltd

Technical Committee Chair

I graduated in Archaeology from Durham University in 1998 and spent some time researching how soil geochemistry affects buried objects before starting a career in field archaeology, quickly finding an aptitude for land survey and geophysics.

I joined Met in 2006 as a Project Surveyor and was made Director in 2012 after developing their underground utility mapping and geophysics department. My career path through research, cultural heritage and the survey industry has had at its core a love of geoscience. I am passionate about education and improving standards in our industry.

I believe it is vital to disseminate knowledge and communicate a better understanding of the technology at our disposal, and how it can be used to provide more effective solutions to the problems we face in our environment. Contributing to TSA’s Technical Committee and the work it produces is one way I can help achieve this.

Steve Hurp

Evolution Surveys Ltd

Technical Committee

I have over 35 years in the survey profession with experience of large-scale topographical surveys, hydrographic, rail, quarry, and landfill.   I am the Managing Director of Evolution Surveys and an instructor at the TSA Survey School.

I think it is important to pass on our knowledge to the next generation of surveyors coming through to start their careers. My aim as a Member of Council is to bring a lot of experience and forward-thinking ideas to help drive and shape the survey profession going forward.

Andy Roberts

Formby Surveys Ltd

Technical Committee

I have over 23 years geomatics experience, initially as a field surveyor, but latterly planning the strategy and growth of Formby Surveys as Managing Director since 2007. Whilst Formby Surveys is a relatively new TSA member company, my involvement with TSA covers most of those 23 years and I have been a contributor to the Survey School since 2004. I am also a serving member of the NW&NW CICES Regional Committee.

My interest in joining the TSA council is to inject modern, open-minded ideas into the organisation and membership, and drive high survey industry standards, share knowledge and improve the overall survey industry image.

After 34 years as a surveyor, I remain proud and passionate about the dynamic industry we work in; and can bring a wealth of knowledge and experience gained from different environments and markets, to assist TSA in continuing the valuable work they do.

My career began as a Land Survey Technician, and I have worked across many sectors since, including Transportation, Water, Defence and Nuclear, and now manage a team of 40 Land Surveyors, Underground Utility Surveyors and Reality Capture specialists.

I have a professional, approachable manner, and am always keen to listen and engage with ideas about industry development.

Mark White

Landscope Engineering Ltd

I work for multi-disciplined survey company LandScope Engineering that focuses on above ground, below ground and underwater mapping.

My educational background was in geology/geophysics before my professional career (last 16 years) focussed on traditional survey and underground mapping. My current role focuses on a mix of commercial / sales, business development and technical expertise. Passionate about driving innovation and hopeful that my ability to articulate complex technical solutions to all sectors can be of benefit to the TSA community.

I am an active member of the wider geospatial community (CICES, EuroGPR, RICS etc) and enjoy presenting and meeting people at events such as Geobusiness.

Maddy Lees

Since graduating from Newcastle University I’ve worked in surveying for more than 25 years, both as a field surveyor and in management roles, in the UK, Middle East and Africa. As Training Manager for 40Seven Ltd I have come to rely on the courses offered by the Survey School as an integral part of our corporate skills development and training programmes, and I see what a great asset to our industry TSA and the Survey School are in developing the skills of surveyors at all levels.

TSA is well placed to take the lead in the development of survey training and industry standards and think that this work is vital in increasing the scope and visibility of the survey profession.

Nathan Spencer

CSL Surveys (Stevenage) Ltd

MIA Committee

Managing director of CSL Surveys (Stevenage), working in the profession for 26 years, FCInstCES. Although originally pursuing a career in Law I was struck by the variety of work and influence that members of TSA had on the wider construction sector. I believe that it is imperative that TSA represents the interests of its members to all sectors of UKPLC and is seen as the go to body for professionalism, Integrity, working practices, education and standards. I would encourage all members to get involved in supporting the wider aims of The Survey Association, Council does value your voice.

Polly Hopkins

Storm Geomatics Ltd

PR Committee

My association with the geospatial profession began in January 2007 when our company Storm Geomatics was born. Being married to a professional land surveyor and one with a passion for reducing flooding I was well versed in the high standards and diverse skills of the profession.

I obtained a Business Studies Degree too many years ago to remember and now have a strong background in business development across varied industries. Creating a strong and robust knowledge of how to ensure a business succeeds is something I can now offer TSA.

Helping to strategically grow our company and time spent alongside geospatial experts has led me to my own passion for securing the future of this vital profession. Without land surveyors our world will not progress and be sustainable both in the natural and built environment.

Becoming a council member for TSA gives me the opportunity to work alongside other council members to uphold the three foundations on which TSA has committed to.

  • Every young person should know about surveying as a career
  • The TSA will help you build a better business
  • Companies with a survey requirement will prefer to use a TSA member

I am committed to promoting TSA and engaging member companies through practical solutions to promote these values together.

Useful to know

TSA is also involved in lobbying Government departments when appropriate and other agencies such as the Environment Agency regarding policies likely to affect or involve the survey profession.

TSA meets regularly with RICS and CICES on a range of issues and has established a group called the SLG, or Survey Liaison Group. This body convenes at regular intervals to examine matters of mutual interest and to ensure that there is little or no duplication of effort by the three bodies.  Representatives from the Geospatial Commission also regularly join SLG meetings.
