One measured record
for highways and drainage.
Brookes Geospatial completed a highways and drainage adoption survey on a residential development in Southport.
The survey captured the completed highway layout together with foul and surface water drainage information, creating a coordinated as-built record of the infrastructure across the site.
Road levels, kerb lines, gullies, chambers, cover levels, invert levels, pipe connections and gradients were recorded and presented within a clear CAD drawing for onward adoption and project coordination.
Full site record
The highway network
measured as built.
The survey records the relationship between carriageways, kerbs, drainage infrastructure and surrounding development.
This provides a single coordinated base from which the completed works can be reviewed and checked against the required adoption information.
Survey workflow
Measure the road.
Trace the drainage.
Survey control
A consistent control framework supported the highway and drainage survey across the development.
Highway survey
Kerb lines, road edges, spot levels, channels and visible highway features were recorded.
Drainage survey
Foul and surface water chambers were surveyed with cover levels, invert levels and connections where accessible.
CAD production
The information was combined into a coordinated as-built drawing for review and onward use.
Highway detail
Road levels and
drainage together.
Detailed road and channel levels were surveyed alongside gullies and drainage chambers so that highway geometry and drainage interfaces could be reviewed within the same drawing.
Drainage information
Foul and surface water.
Clearly identified.
The drainage survey records the key level information needed to understand how the installed system connects through the development.
Chamber references, cover levels, invert levels, pipe connections and recorded gradients are shown alongside the surrounding highway geometry.
Drainage detail
Connections and levels
captured in context.
Localised survey detail allows the drainage network to be read against the finished road and kerb arrangement rather than as an isolated dataset.
Survey information
A coordinated
adoption record.
The completed drawing brings together the key highway and drainage information recorded within the agreed survey scope.
Measured carriageway, channel and surrounding finished levels.
Kerb lines, road edges and relevant highway geometry.
Foul and surface water chamber positions and references.
Recorded cover levels for accessible drainage assets.
Measured invert levels where accessible and within the agreed survey scope.
Observed drainage connections and network relationships shown in context.
Recorded or derived gradients presented where supported by surveyed information.
A coordinated highways and drainage drawing prepared for onward adoption use.
The result
Highways and drainage.
One clear dataset.
The completed survey provided a current as-built record of both the highway infrastructure and the installed drainage network.
Combining both elements into one coordinated drawing gave the project team a practical dataset for adoption review, checking and onward submission.
