We will survey all accessible floors in the property and provide plans showing all visible walls, windows, doors, spot height levels, ceiling/roof heights, window sill/head heights.
Geospatial Survey & 3D Spatial Data Intelligence
In the modern built environment, geospatial surveys provide the accurate 3D data foundation required for design, planning, and construction. From flood risk analysis and terrain modelling to high-rise development and infrastructure projects, precise spatial data ensures alignment between digital design and physical reality.
At XP Surveys, we deliver engineering-grade geospatial data using 3D laser scanning, UAV photogrammetry, and GNSS control. Our services include measured topography, building surveys, and spatial analysis, providing the reliable information professionals need to reduce risk and make informed decisions.
Advanced Geospatial & Engineering Survey Solutions
Our services are designed to support complex, high-value projects where accuracy, detail, and reliability are critical.
Measured Topographical Surveys
We deliver high-resolution measured topographic surveys that capture terrain, features, and constraints with exceptional accuracy. This includes:
- Contours, spot levels, and breaklines
- Roads, kerbs, and hard landscaping
- Buildings, boundaries, and access routes
- Vegetation, trees, and ecological features
- Drainage systems and watercourses
These surveys form the foundation for drainage design, flood modelling, infrastructure planning, and landscape architecture.
High-Rise & Commercial Measured Building Surveys
We specialise in measured surveys of high-rise and complex commercial buildings, providing detailed spatial data for refurbishment, redevelopment and asset management.
Using a combination of 3D laser scanning and drone-based photogrammetry, we capture:
- Accurate floor plans across multiple levels
- Full building elevations and façade geometry
- Roof structures, plant areas, and service zones
- Structural grids, cores, and vertical circulation elements
- External envelope data for cladding and retrofit design
This is essential for office developments, mixed-use schemes, retail environments, and tall structures, where precision is critical for design coordination and compliance.
Flood Risk & Hydrological Survey Support
We provide high-accuracy topographical and geospatial survey data to support flood risk assessments, hydraulic modelling, and sustainable drainage (SuDS) design carried out by specialist consultants.
Using a combination of drone surveys, GNSS control, and detailed measured topography, we capture the terrain and site conditions required for informed flood and drainage analysis.
Our surveys support:
- Accurate terrain models for water flow and drainage analysis
- Catchment and overland flow mapping
- River corridors, floodplains, and site-level relationships
- Integration with environmental and planning requirements
While we do not undertake drainage design or hydraulic modelling, our data provides the reliable foundation required by engineers, hydrologists, and environmental consultants to develop compliant and effective solutions.
This ensures that projects are based on precise, site-specific information, reducing risk and supporting sustainable development.
Bridge & Structural Scanning
We undertake detailed 3D laser scanning of bridges, viaducts, and structural infrastructure, capturing complex geometries that are difficult to measure using traditional methods.
Deliverables include:
- Clearance and gauge analysis
- Structural deformation monitoring
- As-built geometry for refurbishment and strengthening
- Integration into BIM and structural models
Ideal for rail, highways, and civil engineering projects where safety and precision are paramount.

Terrain Obstruction & Line-of-Sight Analysis
We provide advanced spatial analysis to identify terrain obstructions and visibility constraints, supporting:
- Transport corridor design
- Telecommunications and signal planning
- Infrastructure routing and optimisation
- Safety and compliance assessments
This ensures that projects are developed with a full understanding of site limitations and spatial relationships.
Subsurface Utility & Infrastructure Mapping
Our surveys identify and map underground services, reducing risk during excavation and construction.
We support:
- Utility detection and coordination
- Clash prevention and design validation
- Safe excavation planning
- Integration with BIM and GIS systems
This is critical for urban environments and infrastructure-heavy sites.
Aerial Surveys & Corridor Mapping (UAV)
Using UAV technology, we capture high-resolution aerial data for large and complex sites.
Applications include:
- Rail and highway corridors
- River systems and floodplains
- Large-scale land and development sites
- Quarrying and resource management
This allows for rapid, safe, and efficient data capture across difficult terrain or restricted areas.
Volumetric & Earthworks Analysis
We provide detailed volumetric calculations and terrain modelling, including:
- Cut and fill analysis
- Stockpile measurement
- Landform modelling
- Earthworks optimisation
Supporting construction planning, cost estimation, and resource management.
Measured Topography for Environmental & Landscape Architects
We deliver specialist measured topographical surveys tailored for environmental consultants and landscape architects, capturing the full complexity of natural and semi-natural environments. This ensures that all environmental and landscape proposals are based on robust, high-accuracy site data, improving design quality and reducing planning risk.
Our surveys support:
- Landscape design and masterplanning
- Environmental impact assessments (EIA)
- Ecological and biodiversity studies
- Sustainable drainage and water management strategies
We capture:
- Detailed terrain models with contours and levels
- Vegetation, tree positions, and canopy extents
- Root Protection Areas (RPA) for planning compliance
- Watercourses, drainage features, and ecological constraints
- Integration with GIS, CAD, and BIM platforms
