Drone Survey FAQs

A drone survey uses an unmanned aerial vehicle (UAV) equipped with a camera or LiDAR sensor to capture accurate geospatial data of a site from the air. The data is processed to produce maps, 3D models, contoured plans and volumetric calculations. Drone surveys are faster and more cost-effective than traditional ground-based methods for sites above 2–3 acres. Survey type and processing specification determine the output format and accuracy class. See drone survey services →

Drone surveys are used for topographic mapping of development sites, roof and structure inspections, infrastructure corridor surveys, quarry and stockpile volume calculations and site progress monitoring. Output type and format depend on the sensor used and the processing specification agreed before the survey. Common outputs include orthomosaics, point clouds, 3D models and contoured plans. Some applications (e.g. BVLOS inspections) may require additional airspace permissions. See drone survey services →
Using RTK or PPK correction, drone surveys achieve vertical accuracies of ±30mm and horizontal accuracies of ±20mm for standard deliverables. Accuracy requirements are agreed before the survey. Where higher accuracy is required, additional ground control points may be specified. Accuracy class depends on sensor, correction method and GCP density — confirm requirements in the project brief. See drone survey services →

Compared to traditional ground surveys, drone surveys are typically 50–80% faster and cost up to 60% less, with the added benefit of capturing hard‑to‑access areas without scaffolding or site disruption. One recent construction client saved over £8,000 on a 5‑acre site by switching from a conventional topographical survey to our drone‑based solution, receiving survey‑grade data in 5 days instead of 3 weeks.

Sky Scan Surveys provides fixed‑price drone surveys across England, Wales and Scotland. All commissions include data capture, processing and delivery of specified deliverables — no hidden day rates. View full pricing →

LiDAR Survey FAQs

[BUSINESS INPUT REQUIRED: confirm LiDAR drone survey fieldwork unit cost range before publish — e.g. “LiDAR surveys start from £X” — add to /pricing/ page first, then reference here]

GIS/Shapefile data output from LiDAR surveys is available from £349 to £799. Final cost depends on site area, required point density and deliverable specification. All quotes are fixed-price. View full pricing →

Yes — LiDAR systems penetrate tree canopy more effectively than photogrammetry, returning ground-level data through gaps in foliage. Penetration rate depends on canopy density. For very dense woodland, we advise on likely ground return rates before commissioning. Full-waveform systems offer better penetration than discrete-return systems — relevant for dense canopy projects. See LiDAR survey services →
LiDAR is preferable when the site has significant tree canopy, poor lighting conditions, high required point density or is a linear infrastructure corridor. For open sites with good surface texture and lighting, photogrammetry is generally more cost-effective. We advise on the appropriate method at quotation stage. The choice may also depend on deliverable format — LiDAR produces denser point clouds; photogrammetry provides photographic texture. See LiDAR survey services →

LiDAR refers to airborne or mobile scanner systems used for terrain mapping and infrastructure surveys. Terrestrial laser scanning (TLS) refers to static, tripod-mounted scanners used for building and structure capture at close range. Both technologies use laser pulses to build 3D point clouds, but differ in range, platform and application. We offer both — LiDAR for site terrain and TLS for existing structures. Some projects require both on the same site. See LiDAR survey services →

Topographic Survey FAQs

Topographic surveys capture ground levels, surface features and site boundaries for planning applications, development appraisals, flood risk assessments and infrastructure design. Using drone RTK/PPK technology, Sky Scan Surveys delivers topographic surveys to 3rd-order accuracy. Standard deliverables include a 1:500 or 1:200 contoured plan, DTM and spot height grid. Planning authorities may specify accuracy tolerances — confirm these before commissioning. See topographic survey services →

Using RTK/PPK correction, we deliver topographic surveys to 3rd-order accuracy with ±30mm vertical accuracy as standard. Vertical and horizontal tolerances are confirmed in the project quotation. Additional ground control points can be added for higher accuracy requirements. Some planning authorities specify accuracy tolerances — confirm before commissioning. See topographic survey services →

[BUSINESS INPUT REQUIRED: provide 2–3 sentences on why a client would need a topographic survey — e.g. planning requirements, design base, drainage/flood risk, common use cases in your experience]

Topographic surveys are the dimensional foundation for planning applications, development site appraisals and flood risk modelling. Sky Scan Surveys delivers fixed-price topographic surveys across England, Wales and Scotland. See topographic survey services →

We routinely survey sites from 3 acres to several hundred hectares in a single mobilisation. For very large sites, we plan multi-flight operations and confirm timescales before commitment. Site access and airspace constraints are factored in at the quoting stage. Linear sites (e.g. infrastructure corridors) may require additional flight days regardless of total area.

Measured Building & Terrestrial Laser Scanning FAQs

Laser scanning captures precise 3D measurements of structures for as-built BIM documentation, heritage recording, structural monitoring, façade surveys and construction clash detection. It produces a registered 3D point cloud from which drawings or BIM models are produced. Laser scanning (TLS) is for close-range structure capture; airborne LiDAR is used for terrain and landscape. Applications span architecture, engineering, construction and cultural heritage. See measured building survey services →

We produce BIM models at LOD 200, LOD 300 and LOD 400, working to the BIM Forum LOD specification. Revit BIM models at LOD 300 are priced from £799 to £2,499 with RVT and IFC output. LOD requirements must be confirmed in the project brief as they directly affect data collection methodology and processing scope. LOD 350 and above may require additional site access and equipment — confirm at quotation stage. See measured building survey services →

A measured building survey includes floor plans to all levels, external elevations (all faces) and building sections, delivered in AutoCAD (.dwg) or Revit (.rvt). Scope is confirmed in the quotation, including which internal areas require access. Additional features (rooflines, services risers) can be added on request. Significant access limitations may affect completeness — agree scope before survey. See measured building survey services →

Measured building surveys are required for planning applications affecting existing buildings, pre-refurbishment design, listed building consent and building regulations submissions. The survey provides the accurate dimensional base for all subsequent design work — typically specified by the project architect or planning consultant. Listed buildings may require additional accuracy specifications or RICS compliance. See measured building survey services →

A measured building survey produces 2D drawings (floor plans, elevations, sections). Scan-to-BIM converts a 3D point cloud into a structured Revit model with building elements modelled to a specified Level of Detail (LOD). Scan-to-BIM is required when 3D design coordination, clash detection or BIM-level documentation is needed. A measured survey is sufficient for most planning and refurbishment applications. LOD requirements (200, 300, 400) must be specified before commissioning as they directly affect methodology and cost. See measured building survey services →

Compliance & Coverage FAQs

Yes — Sky Scan Surveys holds a CAA Operational Authorisation for commercial drone operations. All pilots hold the GVC (General Visual Line of Sight Certificate) and operations are conducted under a current CAA-approved Operations Manual. CAA documentation is available on request. Authorisation applies to commercial operations across England, Wales and Scotland. See drone survey services →

We cover England, Wales and Scotland, with most projects mobilised within 48 hours of quote acceptance. Mobilisation is subject to airspace and weather conditions. Restricted airspace zones (MOD sites, airports) require extended permit lead times — flagged at quotation stage. Offshore or international projects can be discussed on request. Request a quote →
A standard development site survey typically takes 2–4 hours on site; data processing and delivery takes 2–5 working days after the flight. Flight time varies by site size and survey type. For large or complex commissions, timescales are confirmed in the project quotation. Weather and airspace availability affect scheduling — we build this into the project timeline. Request a quote →

The main factors are site area, survey type, accuracy specification and deliverable format. Restricted airspace or unusual site access requirements may also affect the quotation. We confirm all factors in a fixed-price quote before mobilisation. Quoted price covers the agreed scope — out-of-scope changes require a revised quotation. View full pricing →
