What is the difference between LiDAR and photogrammetry?

LiDAR uses laser pulses to directly measure distances, producing dense, accurate point clouds regardless of lighting conditions. Photogrammetry uses overlapping photographs to reconstruct 3D geometry. QRC uses both — LiDAR for precision-critical capture and photogrammetry for aerial texture and orthomosaic production.

How accurate is mobile LiDAR scanning?

Our mobile LiDAR systems achieve ±2–5mm accuracy, which meets or exceeds survey-grade requirements for design, coordination, and construction workflows.

Can you scan occupied buildings?

Yes. Mobile LiDAR scanning works in occupied spaces without disrupting normal operations. We coordinate with your team to minimize impact.

What file formats do you deliver?

We deliver in all industry-standard formats including .rcp, .e57, .las for point clouds, .rvt for Revit models, .dwg for CAD drawings, and web-based viewers for stakeholder review.

Do I need to know which capture method to use?

No. During our scoping call, we recommend the right capture strategy based on your project type, site conditions, and deliverable needs. Most clients just describe the problem — we prescribe the method.

How long does processing take?

Point cloud delivery typically takes 3–7 business days. BIM models and drawings take 2–4 weeks depending on scope. Expedited timelines are available and quoted separately.

Technology

How QRC Captures Reality.

LiDAR scanners, drone platforms, and a rigorous production pipeline.

The technology behind survey-grade spatial data for AEC professionals — from XGRIDS SLAM handhelds to aerial LiDAR to production-grade Gaussian Splat rendering.

Get a Recommendation Explore Hardware

Gaussian Splats. Real-Time Rendering. Survey-Grade Truth.

Our XGRIDS workflow produces 3D Gaussian Splatting output alongside survey-grade point clouds — drop the result into Unity, game engines, or web viewers for fully immersive review, or hand off registered clouds for BIM.

Every point cloud starts with a QRC operator on-site — calibrated equipment, verified in the field.

Capture Methods

Six Ways We Capture and Deliver Reality

Mobile LiDAR

Terrestrial scanning for interiors, exteriors, and complex occupied spaces. Millimeter-accurate point clouds captured in a fraction of the time of manual measurement.

Aerial LiDAR & Drone

UAV-mounted LiDAR and photogrammetry for large sites, campuses, rooftops, and terrain — georeferenced from the air.

Scan-to-BIM

Point clouds converted into intelligent Revit models at LOD 200–400 — ready for design, coordination, and construction workflows.

Virtual Tours & Digital Twins

Immersive 3D walkthroughs built from scan data, enabling remote site review, stakeholder buy-in, and marketing use.

Construction Progress Documentation

Periodic captures compared against design models to track installation accuracy, identify deviations, and verify field conditions.

Quality Control & Data Confidence

Every dataset is registered, cleaned, and checked against accuracy benchmarks before delivery. No guesswork, no surprises.

In the field

Every Point Cloud Starts With a Calibrated QRC Operator.

No black boxes, no off-shore capture. Our field team runs XGRIDS SLAM handhelds, terrestrial scanners, and Part 107 drone platforms with calibration and QA validated on-site before the file ever leaves the truck.

02 · Pipeline

How Raw Capture Becomes Decision-Ready Deliverables

Every scan moves through five quality-controlled stages before it reaches your team.

Capture

Raw spatial data collected on-site via LiDAR scanners or drone platforms.

Registration

Individual scans aligned into a unified, georeferenced coordinate system.

Cleaning & QA

Noise removed, accuracy validated, and datasets checked against benchmarks.

Production

Data transformed into project-specific deliverables — models, drawings, tours, or reports.

Delivery

Final datasets packaged in your preferred format with documentation and team walkthrough.

Deliverables

What Clients Can Receive

Every project is different. These are the deliverable formats available from our production pipeline.

Registered point clouds (.rcp, .e57, .las)

Revit BIM models (.rvt) at LOD 200–400

As-built floor plans, elevations, sections (.dwg / PDF)

Orthomosaic imagery and aerial photography

Digital surface and terrain models (DSM / DTM)

Immersive 3D virtual tours

Construction progress comparison reports

Thermal imagery and condition assessments

Navisworks exports for clash detection

Web-based point-cloud viewers

Studio in Action

From Field Capture to Project-Ready Dataset

Lixel Studio initializes the SLAM trajectory, registers scans, and prepares the output for downstream AEC tools — the software half of every QRC deliverable.

Integration

How This Fits Into AEC Workflows

QRC deliverables are built to plug directly into the tools AEC teams already use — Revit, AutoCAD, Navisworks, Civil 3D, and web-based collaboration platforms.

Point clouds and BIM models serve as the spatial foundation for design development, MEP coordination, clash detection, construction verification, and facility management.

Whether you're an architect starting schematic design, an engineer modeling existing MEP systems, or a contractor verifying installation accuracy — QRC data fits your workflow without conversion headaches.
