One measured base
for the whole site.
Brookes Geospatial completed a detailed topographic survey across approximately 23,000 m² of land in Preston, Lancashire for an architectural client.
The survey recorded the existing buildings, ground levels, boundaries, vegetation, hardstanding and visible site features across a varied site.
The finished drawing created a clear, coordinated representation of existing conditions, giving the design team a reliable measured base for onward architectural work.
Measured detail
Buildings, levels
and site features.
Detailed survey information was captured around the existing buildings and landscaped areas, including spot levels, roof detail, surface changes and visible features.
This level of detail allows the architectural team to understand both the form of the site and the relationship between existing structures, access areas and surrounding ground levels.
Survey workflow
Control the site.
Capture the detail.
Site control
A consistent survey framework supported the capture of detail across the full 2.3 hectare site.
Topographic capture
Buildings, boundaries, surfaces, vegetation and visible site features were measured across the survey area.
Level coverage
Spot levels and terrain information were recorded to define the existing form and changes in ground level.
CAD production
The measured information was processed into a clear coordinated topographic drawing for architectural use.
Full site survey
2.3 hectares.
One coordinated drawing.
The completed topographic survey brings the wider site together in one drawing, combining terrain, structures, boundaries, vegetation and visible features across the full survey extent.
Existing conditions
Terrain and detail.
Read together.
A useful topographic survey is more than a collection of points. The drawing needs to show how levels, features and structures relate across the site.
By presenting the measured detail in context, the architectural team can work from a single drawing that clearly communicates the existing site before design progresses.
Survey detail
From overall terrain
to local detail.
The wider survey extent is supported by detailed information around existing buildings, access areas, landscaping and changes in surface level.
Survey information
A measured base
for design.
The completed survey brings together the principal existing features and level information recorded within the agreed topographic survey area.
Spot levels and terrain information defining the existing site form.
Terrain interpretation presented across the wider survey area.
Existing building footprints and visible external detail recorded in context.
Visible boundary lines, walls, fences and changes around the site perimeter.
Hardstanding, paving, gravel, grass and other visible surface changes.
Trees, hedges and relevant landscaped features shown across the site.
Visible features and level changes recorded within the agreed survey scope.
A coordinated drawing prepared as an architectural base for onward design work.
The result
23,000 m².
Clearly understood.
The completed survey gave the architectural team a detailed measured record of the existing site across the full 2.3 hectare area.
With buildings, levels, terrain, boundaries and surrounding features coordinated in one drawing, the project could move forward from a clear and practical base of existing site information.
