3D BIM Laser Scanning Vs. Photogrammetry – Choose the Right Technology for Construction

Today, it’s difficult to envisage the world without digital technology. Nevertheless, the physical world is

getting designed & constructed using conventional 2D blueprints, which is yet to be seized in a digital

setup. This creates a challenge for the AEC (Architectural, Engineering & Construction) professionals to

integrate the as-built designs into renovation projects.

Conventional Imaging Technique – Photogrammetry: Conventional imaging techniques like

Photogrammetry facilitated this process by letting engineers reconstruct photographs of as-built

situations and weave in GPS (Global Positioning System) coordinates for creating collaborative 3D

models. Photogrammetry indeed allows you to encompass a considerable amount of ground, but it

does with low accuracy.

3D Laser Scanning for Building Renovation & Retrofitting: 3D laser scanning consists of a

smaller footprint of data, collected to a higher level of accuracy. Laser scanners collect surface data

through a laser beam pointed at the surface. The technology often uses drones or UAVs (eradicating

expensive LiDAR assembly methods) and transforms that data into a point cloud. Then the point cloud

data gets imported into tools like Autodesk ReCap, transforming it into a 3D model or 2D drawing

equipped for additional design in just a matter of minutes. Besides laser scanning, Autodesk Recap

converts aerial as well as to object photographs of 3D models.

Why should you consider 3D Laser Scanning to BIM Technology?

Check out the deliverables and benefits of laser scan point cloud to BIM:

Deliverables from Point Cloud to BIM include:

3D BIM Model Creation for Renovation & Extension – 3D Model gets created using

BIM (Building Information Modeling), according to point cloud scan to BIM for enhancing

transparency & streamlining communication. BIM technology also facilitates quick decision

making during the As-Built Phase.

As-Built BIM Drawing Preparation – As-Built drawings can be created for Plan,

Elevation & Section Sheet. As-Built also provides a comprehensive tool for the planning of

future projects, like extension & renovation from laser scan point cloud.

4D BIM Construction Scheduling – 4D BIM is used for construction scheduling of

renovation. Point Cloud or 3D laser scanning to BIM Modeling facilitates the revamp of old

buildings for creating interest among architects.

BIM Facility Management – BIM engineers enable project team members to combine

submittals from point cloud scan during project renovation through facility management.

Our experts accomplish complete contact records of the project in the required fields.

Benefits of using Laer SCAN to BIM services:

Create as-built 3D BIM models for existing buildings & renovation.

3d models are updated as per the contractors, facility managers, or architect's prerequisites in a

simulated environment.

Modeling using point cloud to BIM Services data helps the architecture to make decisions about

wanted or unwanted components and structures of the building.

Laser Scanning to BIM technology creates a clash simulation analysis for Architectural & MEP

services at an initial phase of feasibility review while adding new services.

Nowadays people look for more accuracy and in this regard, 3D BIM Laser Scanning matches the perfect requirement of the construction domain compared to conventional imaging technique – photogrammetry.
