Construction
As-built survey
A solid baseline for CAD/BIM: capture as-is geometry, verify deviations, and update models and plans to date.
We deliver LiDAR scanning for sites and assets of any complexity — from terrain and land parcels to buildings, linear infrastructure, industrial facilities and indoor environments — operating across Europe and on projects worldwide. Our deliverables are production-ready and fully compatible with CAD and GIS workflows.

Tree-by-tree surveys, inventory and mensuration, crop field mapping, and biomass estimation.
Typical LiDAR scanning tasks
A practical set of use cases — from engineering baselines to change detection and analysis.
Use cases
- Engineering baseline: point cloud, surfaces, plans for CAD/GIS/BIM.
- Profiles and cross-sections: along routes/corridors, specified lines, or chainage-based sections.
- Design and refurbishment: accurate “as-is” geometry to avoid repeat site measurements.
- As-built verification: verify delivered work, deviations and volumes (as per the brief).
- Asset inventory: attribution of features (poles, fences, signs, drainage, cables, manholes and more).
- Clearance checks: headroom, offsets, safe distances and crossings (to brief-defined criteria).
- Mining: quarries/stockpiles, slope modelling, volume calculations, before/after monitoring.
- Change detection: epoch comparison, difference maps, deformation dynamics (per monitoring method).
- Challenging conditions: vegetation penetration (ALS), continuous corridor capture without stops (MLS).
If your task is non-standard, describe the site, constraints and expected outputs — we’ll propose the best technology and deliverable set for your workflow.
Three technologies for different site conditions
We choose the approach based on scale, access, geometry and output requirements.
ALS
Airborne LiDAR (UAV)
The best option for terrain, large areas, quarries, corridors and complex vegetation conditions.
- Fast coverage for areas and long corridors.
- Works well on slopes and complex terrain; canopy penetration depends on conditions.
- Accuracy is fixed in the brief and verified through checks.
MLS
Mobile LiDAR (MLS)
Ideal for linear assets and infrastructure: roads, streets, perimeters, industrial sites, façades and street furniture.
- High detail along the capture route.
- High productivity with minimal disruption to traffic (site-dependent).
- Well suited to inventories and geodata updates.
Airborne Laser Scanning enables the rapid survey of large areas and linear assets, while Mobile Laser Scanning provides higher-resolution capture of specific sections where greater detail is required.
What we typically need from you to make the output genuinely useful
A short checklist that saves time and reduces the risk of rework.
Brief inputs
To match the requirement precisely
- Site boundaries: area/corridor, key zones and priorities.
- Expected outputs: point cloud, DTM/DSM, profiles/sections, 3D, reporting.
- Coordinate reference system and vertical datum: match your project setup.
- Accuracy requirements and how they will be verified (checks, tolerances).
- Your standards: layers, naming, units, DWG/DXF templates (if any).
Site conditions
To avoid wasting time on site
- Access rules: permits, escort requirements, work windows, H&S requirements.
- Constraints: UAV flight restrictions (ALS), traffic movement (MLS), restricted areas.
- Conditions: vegetation, reflective surfaces, dust/smoke, water, tight passages.
- Existing control/check points — or whether we can establish them (if needed).
- Data delivery: media/cloud, folder structure, delivery timeline.
Common add-ons
What clients often add to LiDAR scanning
- Point cloud classification (ground/vegetation/buildings/poles, etc.) for GIS and design workflows.
- Feature extraction and asset inventories with layers/attributes.
- Epoch comparison: difference maps, change tables, before/after control.
- Profiles/cross-sections by chainage or specified lines (including cross-sections).
- BIM prep: simplified model, coordinate referencing, clash checks (as per the brief).
- QA/QC report: methodology, control checks and accuracy summary.
Deliverables and formats
We agree the file list and layer structure before starting. You receive “ready-to-use” outputs for your environment.
| Deliverable | Format | Contents |
|---|---|---|
| Point cloud | LAS/LAZ, E57 | Merged and cleaned point cloud; classification if required |
| Surfaces | DWG/DXF | DTM/DSM, contours, slopes, derivative maps |
| Profiles and cross-sections | DWG/DXF, PDF | Along specified lines, routes/corridors, chainage-based sections |
| 3D/mesh (optional) | OBJ/FBX/PLY | For visualisation and engineering checks |
| QA/QC report (optional) | Control checks and accuracy summary |
If you have a corporate standard for layers/attributes and folder structure, share an example — we’ll match your format.
How the work runs
A transparent workflow: inputs → technology selection → fieldwork → processing → QA/QC → delivery.
Inputs & brief
We define the scope: site boundaries, accuracy requirements, CRS/vertical datum, deliverables, layer standards and reporting. We agree the QA/QC method and acceptance criteria.
Technology selection
We choose ALS/MLS (or a combination) based on access, terrain, built environment, vegetation and GNSS availability/stability. We plan routes/corridors, data density and verification checks.
Fieldwork
We capture data using the selected method: ALS (UAV-based) or MLS (route-based). Where required, we carry out control checks and collect supporting data for subsequent processing.
Office processing
Point cloud merging and cleaning, with classification where required. Surface generation (DTM/DSM), contours, slopes, profiles/cross-sections, and 3D/mesh (if included). We build layers and folder structure to your standard.
Quality control & delivery
We verify accuracy to the agreed scheme (check points / control checks), produce reporting if required, export to the requested formats and deliver a CAD/GIS/BIM-ready dataset.
Project examples
Timeline and pricing
Depends on project scale and processing requirements.
Timeline
From 1–2 days to several weeks
Typically: mobilisation and capture — from 1–2 days (or per monitoring schedule); processing and reporting — from 1–2 days and longer for large sites and advanced analytics.
Pricing
Quoted on request, after the brief
Cost depends on capture type (visual/photogrammetry/LiDAR), area/route length, accuracy requirements and deliverable formats, site complexity, and logistics.
For a quick quote: site type, location, project aim, desired outputs (report/orthophoto/3D/point cloud), approximate area/corridor length, and required timelines.
