3D Laser Scanning and LiDAR FAQs

What Is 3D Laser Scanning?

3D laser scanning is a survey method where a terrestrial scanner stands on a tripod and records millions of precise points across a building, plant or site. The result is a point cloud of existing conditions that we turn into drawings, models and measurements — typically 2–4 hours on site, and it runs on active construction sites without stopping work.

What Is a LiDAR Scanner Used For?

A LiDAR scanner measures distances with laser pulses, from the ground or from a drone. We use it for terrain and corridor mapping, infrastructure and industrial facilities, volumetric studies and construction progress monitoring, with coverage across India.

Point Cloud and CAD Drafting FAQs

What Is Point Cloud Data?

Point cloud data is the collection of XYZ coordinates captured during a scan — every point records an exact surface position, so the full set describes the building or site as it exists today. We deliver it in .e57, .las or .rcp formats depending on the software your team works in.

Can Point Cloud Data Be Converted into CAD Drawings or a 3D Mesh?

Yes. From the scan we model floors, ceilings, elevations, sections and layouts as CAD drawings in DWG or PDF, and build 3D mesh or surface models when you need the shape of the existing structure rather than line work.

Scan-to-BIM and BIM Outsourcing FAQs

What Is Scan-to-BIM?

Scan-to-BIM is the process of building an as-built BIM model from a laser scan instead of from new design intent. The point cloud gives the model real measured geometry, so walls, services and structures line up with what is actually on site — useful for renovation, retrofit and clash checking.

What Do BIM Outsourcing Services Include?

Our BIM outsourcing covers model creation from point clouds or existing drawings, LOD development, drawing extraction from the model, and coordination support with your design team. Files arrive in Revit or IFC, with a GST invoice from LDR Survey Pvt Ltd.

Drone Survey and Photogrammetry FAQs

What Is Photogrammetry?

Photogrammetry is turning hundreds of overlapping drone photographs into measured outputs — orthophotos, contour maps, digital surface and terrain models, and 3D representations. It suits large sites, open terrain and progress records where flying a drone is faster than ground survey.

Which Drone Survey Deliverables Are Available?

You can order orthophotos, contour mapping, volumetric analysis, 2D and 3D outputs and periodic construction progress monitoring. All flights are DGCA-compliant, and the data can be combined with ground control for survey-grade accuracy.

Virtual Tours and Digital Twin FAQs

What Is a 360-degree Virtual Tour Viewer?

It is a shareable browser link that lets anyone walk through a 360° virtual tour of a site or property using panoramas — no software install, works on a phone or laptop. NRI and out-of-city clients use it to inspect a property remotely and decide with confidence.

What Is a Digital Twin?

A digital twin is a living digital copy of a site or asset, built from scan and survey data and refreshed as conditions change. It gives facility, design and project teams one measured reference for planning, monitoring and handover.

Pricing, Deliverables and Project Timelines

Quick answers to what most clients ask before getting started.

  • Pricing depends on project size and scope. A basic 3D site scan starts from ₹8,000 based on sqft. 360° images: 5 snaps – ₹6,000; 10 snaps – ₹11,000. Exact quote on a free consultation — no hidden charges.
