RISQS-accredited rail survey, delivered by JWG
RISQS accreditation sits with JWG, Survey Solutions’ rail business, so rail work is delivered by the team that actually holds the accreditation instead of by a generalist team borrowing it. That distinction matters to a Network Rail supply chain, and we would rather make it plainly than leave you to find out later.
Rail work leaves little room for error. A missed level or an unknown cable can cost you a possession, and a lost possession can cost weeks. Rail work is delivered with JWG Survey & Engineering, our group’s rail company, which is RISQS-registered, so you get accurate data first time.
Rail surveys we deliver
Engineering and topographic surveys
Our engineering surveys and topographic surveys give designers an accurate picture of the track corridor, boundaries and existing structures. We support new lines, stations, platform projects and renewals. Then we check that what gets built matches the design, so errors are caught before they cost you.
Bridge, tunnel and culvert surveys
Bridges, tunnels and culverts need accurate records before any repair or renewal. We survey the structure and what sits around and below it. Recent work includes a detailed bridge survey on the Settle–Carlisle Line, part of an ongoing programme for a rail design client.
Underground utility surveys
Buried cables and pipes are a major risk on any rail site. Our underground utility surveys find them before you dig, so excavation is safe and services stay running. We also assess subsurface structures such as culverts and tunnels.
Hydrographic surveys for bridges over water
Where the railway crosses rivers and estuaries, what lies under the water matters. Our hydrographic surveys map depth, sediment build-up and obstructions that can affect bridge foundations. Our land surveys cover the ground either side for route planning.
Rail Monitoring
Survey Solutions bring dedicated rail survey and engineering management expertise. Our rail monitoring services support track works, bridge works, tunnel works, platform projects, renewals, adjacent construction, embankment schemes, temporary works and long-term asset monitoring.
Proven on live rail structures and at corridor scale
We can point to a bridge survey on the Settle-Carlisle line, covering deck-side topographic survey, 80 metres of track, and elevations and sections through three arch spans and piers. Alongside the switch and crossing scanning we deliver for Voestalpine Turnout Technology, now into a second programme year, that gives you evidence at both live-structure and corridor scale.

Rail FAQ’s
Surveying and monitoring support for rail asset owners, engineering consultants and contractors—where accurate data is crucial for safety, efficiency and compliance.
Yes, rail programmes often rely on short access windows, so we plan capture and deliverables around agreed possessions and safety requirements.
To provide precise data on topography, boundaries and existing structures for planning/design, and to ensure construction is delivered accurately to spec.
Yes, we support rail infrastructure development and maintenance contexts (scoped to your specific project constraints).
Location/route extents, scope, access constraints, safety requirements, outputs, and programme dates (including any possession windows).
RISQS accreditation sits with JWG, our rail business, and JWG is who delivers the rail work, so it is never a generalist team using someone else’s accreditation.
It is a bridge survey on the Settle-Carlisle line, covering deck-side topographic survey, 80 metres of track, and elevations and sections through three arch spans and piers.
You need rail monitoring when work could move track, bridges, tunnels or platforms. That includes renewals, embankment schemes, temporary works and construction next to the line. Monitoring shows movement early, so you can act before it affects safety or service. It can also run long-term on ageing assets.
