Surveying within culverts and deep tunnels are fast becoming a lost art and accordingly, our specialist confined spaces teams have never been busier. Water industry contracts mainly involve the precise traversing, detailing and alignment of deep sewers, culverts, branches and connections.
Typically working in tunnels of 1.2m diameter and above, these surveys require specialist surveyors applying tried and tested methods in an often hostile environment. Commonly undertaken to enable the design of an above-ground piling layout, we recently positioned the entire Moorfields underground railway station complex in Liverpool relative to our surface topographical survey above (watch video). Other surveys have also been completed to facilitate new connections, chambers or other changes to a working system.
Complex Confined Spaces
We have also introduced 3D laser scanning methods to a number of more complex confined spaces and environments to enable design, client visualisations and maintenance planning programmes without unnecessary man-entry.
