A detailed record
of a complex site.
Brookes Geospatial completed a detailed topographical survey in Higham, Lancashire, capturing the existing levels and physical features across the site.
The survey recorded the main building, surrounding walls, access routes, hardstanding, vegetation, boundaries and changes in ground level.
With substantial level variation across the site, contour information and spot levels formed an important part of the finished drawing, giving a clear picture of the existing landform and its relationship with the built features.
Full site survey
Levels, features
and landform together.
The finished survey brings together the building, access, boundaries, landscape features and surrounding terrain in one coordinated drawing.
Spot levels and contours were used throughout the site to communicate the significant changes in elevation clearly.
Survey workflow
From terrain
to technical drawing.
Survey control
A coordinated control framework supported consistent measurement across the full site.
Site measurement
Buildings, walls, boundaries, access routes, vegetation and visible features were recorded.
Level survey
Dense spot levels were captured to represent the site's substantial changes in ground level.
CAD production
The survey information was processed into a coordinated drawing with contours and feature detail.
Existing features
Detail around
the building.
The survey captures walls, paving, steps, thresholds, vegetation and external levels around the existing property, providing useful context where the building meets the surrounding terrain.
Site levels
Understanding
the slope.
The site sits across pronounced changes in elevation, making accurate level information central to the usefulness of the survey.
Spot levels and contours were recorded across the wider site to show how the existing building, access and landscape features relate to the natural ground.
Building context
The structure
in its surroundings.
Close survey detail around the property allows the built form and immediate external areas to be read against the wider topography.
Survey information
A complete picture
of the existing site.
The topographical drawing provides a coordinated measured record of the main physical and level information within the agreed survey area.
Measured ground and surface levels throughout the site.
Contour information showing the wider shape and fall of the land.
Existing building extents and key external interfaces.
Stone walls, block walls, fences and other visible boundary features.
Tracks, paving, steps, concrete and other surfaced areas.
Trees, grass areas and relevant landscape features.
Relevant building threshold and external interface levels.
A clear topographical drawing prepared for onward project use.
The result
Existing conditions.
Clearly measured.
The completed survey provides a detailed measured record of both the built features and the surrounding topography.
The drawing gives the client a reliable existing-condition base for future design, planning, assessment or coordination work.
