Question 1

What is the accuracy specification for your 3D photogrammetry models?

Accepted Answer

We use RTK-equipped drones (DJI Mavic 3 Enterprise RTK, Matrice 30T) with multi-point ground control point (GCP) validation to achieve ±1–3 cm horizontal and ±2–5 cm vertical accuracy per ISO 19157 standards. Every GCP is surveyed independently and incorporated into the Pix4D and RealityCapture processing pipeline. Accuracy is verified and reported on every delivery with confidence intervals and residual analysis.

Question 2

What file formats and CAD/BIM platforms do you support?

Accepted Answer

Complete format compatibility: OBJ and FBX textured mesh models (6K color), LAS and PLY classified point clouds (WGS84 UTM, LAS 1.4 spec), GeoTIFF orthophoto mosaics with spatial reference, DXF contour vectors, and Revit (RVT) + IFC 4 BIM models. All outputs compatible with AutoCAD Civil 3D, ArcGIS, QGIS, CloudCompare, Unreal Engine, Unity, Revit, and standard GIS/CAD/BIM software stacks.

Question 3

How fast is your turnaround from flight to delivery?

Accepted Answer

Standard turnaround is 24–48 hours from flight completion to QA-checked delivery. Processing is performed on-site using fully licensed Pix4D and RealityCapture workflows, eliminating cloud upload delays and external dependencies. Large-scale projects (>200 hectares) or multi-flight campaigns may require additional processing time. Rush deliverables available upon request.

Question 4

What are your flight and equipment credentials?

Accepted Answer

Majed Aerial Solutions holds dual licensing from GACA (General Authority of Civil Aviation, Certificate UA-38575) and GEOSA (General Authority of Surveying and Geospatial Information) — the highest credential stack for commercial aerial survey and geospatial work in Saudi Arabia. Fleet includes RTK-equipped DJI Mavic 3 Enterprise RTK, Matrice 30T, Mavic 3 Pro, and Mavic 3 Multispectral aircraft. All pilots are trained and insured per GACA regulations.

Question 5

Do you work with engineering firms and government projects?

Accepted Answer

Yes. We work with engineering consultancies, construction contractors, infrastructure operators, real estate developers, and government entities across all regions of Saudi Arabia. Our GACA (UA-38575) and GEOSA dual licensing meets all credential requirements for official survey work, government projects, and engineering design workflows. We maintain data security, insurance, and contractual compliance for B2B and government clients.

Question 6

Does the drone survey require site access or work stoppage?

Accepted Answer

Flight paths are planned to maintain safe distance from personnel and equipment. Typical site surveys require 1–3 hours of flight time depending on site area and complexity. Operations do not require site closure or work stoppage — surveys can be conducted during normal site activity with appropriate safety coordination. Detailed safety briefing and airspace deconfliction are provided before every mission.

Question 7

How does GCP (ground control point) validation improve accuracy?

Accepted Answer

Ground control points are surveyed reference locations marked on the site before flight. Their known coordinates (within ±2 cm) are incorporated into the photogrammetric processing pipeline, allowing the software to scale and georeference the entire 3D model to absolute real-world coordinates. This eliminates drift, ensures consistency across multiple flights, and enables survey-grade accuracy claims. We typically deploy 5–15 GCPs per 50 hectares depending on terrain complexity.

Question 8

Can you provide volumetric analysis or cut/fill calculations?

Accepted Answer

Yes. From the 3D point cloud, we derive digital surface models (DSM) and perform volumetric analysis including earthwork volumes (cut/fill), stockpile measurements, deposition zones, and progress tracking. Volumetric accuracy is typically ±3–5% dependent on point cloud density and baseline surface definition. Deliverables include volumetric reports, contour maps with highlighted cut/fill zones, and temporal comparisons for construction progress tracking.

Question 9

What about confidentiality and data security?

Accepted Answer

All project data is treated as confidential. Deliverables are encrypted, access-controlled, and never shared with third parties. Processing is performed on secure, isolated systems with no cloud uploads unless explicitly requested by the client. Data deletion protocols are followed per contract. We maintain liability insurance and comply with all Saudi data protection and airspace regulations.

Question 10

How is pricing structured for 3D photogrammetry projects?

Accepted Answer

Pricing is project-based and depends on: site area (hectares), terrain complexity (flat vs mountainous), required deliverables (mesh, point cloud, BIM, contours, etc.), accuracy specifications (standard ±1–3 cm or tighter), and processing timeline. For a typical 50-hectare survey with standard deliverables, expect 48–72 hour turnaround and project-specific quoting.
