Topographical Surveys

From depots and platforms to embankments, car parks and more, our experienced and professional land surveyors deliver precision topographical surveys of the UK's rail network in accordance with Network Rail Standard NR/L2/TRK/3100.

At the heart of almost every construction or civil engineering project, a topographic survey is usually procured at the earliest stages of a job, providing information vital to both design and construction teams as well as a variety of other stakeholders.

Topographic Survey

A topographic survey is an in-depth analysis of a parcel of land carried out by a professional land surveyor. Whilst information collected could include both natural and man-made features, a topographic survey would also provide comprehensive elevation information, ideal for mapping contours, gradients and more.

Not simply valuable in isolation, a precision topographical survey can also be used to complement the results of other pre-construction works. From accurately plotting the findings of utility mapping or CCTV surveys to mapping the position of boreholes, a well-considered topo survey can be enhanced to provide significant added value to the majority of rail engineering projects.

Using the very latest survey equipment and backed up by a time-served delivery team, our surveyors hold all certifications necessary for working throughout the nation’s railway infrastructure.
