Surveying
project. For example S&C surveys need higher accuracies partly due to the trend towards modular renewal. The old S&C is often cut out and replaced in a single possession with no room for dimensional error. All joints and welds are also detailed which requires not only a geomatics surveyor but a railway surveyor to be involved. TSA member companies provide such experience. They also provide track access planning - crucial to maximising possession periods - and an understanding of the role surveyors can provide into the future for the smooth running of the 365- day railway network.

seminars such as that provided by the Permanent Way Institution at the end of February on ‘BIM and S&C’.
Understanding technology is key Understanding how to use the new technology, software and systems properly with integrated quality control checks is key to maximising value to the railway
The association has written and published a series of guidance notes, all of which are downloadable free of charge from its website at:
www.tsa-uk.org.uk. Most TSA guidance notes and client guides are additionally endorsed by the RICS and the CICES. The notes cover a wide range of subjects all designed to help clients and members alike to understand and make
the most of modern surveying techniques. Subjects covered include accuracies, laser scanning, specifications, building surveys, and working on railways.
In 2008 TSA engaged with other
major stakeholders in producing a set of guidelines to de-mystify the use of GPS. The final results are presented in a set of best practice guides for use both by surveyors and clients. The original study was subsequently updated and launched at the HQ of the Ordnance Survey in April 2012. The document has already been adopted by organisations such as the Environment Agency and Network Rail. Both the 2008 GPS guidance document and the 2012 GNSS document can also be downloaded free of charge from the TSA website. In 2011 TSA released a new guidance
document on Utility Mapping. The document was two years in the making and has been endorsed by a number of major organisations as well as Mark Prisk MP, at that time the Business and Enterprise Minister.
Mr Prisk wrote: ‘I am pleased to see that The Survey Association has produced this document which is not only written in plain and concise English but which will also become a vital source of information for all those concerned with the UK’s construction industry. Clients and contractors alike will find the Utility Guidance note a useful document when commissioning a utility survey and considering health and safety issues.’ A video has been produced to
accompany the document and this can be viewed on the TSA’s website. TSA also liaises with the RICS and
CICES on a range of issues and has established a group called the SLG, or Survey Liaison Group. This body meets 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.
