For decades, builders and general contractors have worked with Existing Conditions to 3D laser scan buildings and project sites.

Existing Conditions 3D laser scanning provides a solution to outdated as-built data and drawings through the use of survey-grade laser scanners, delivering site data that is complete, clean and accurate. Since as-built drawings are often misdrawn, poorly kept, or even lost, site documentation has been perfected through Existing Conditions' 3D laser scanning expertise. With the capacity to create a true digital twin, Existing Conditions provides accurate reality capture data fast and efficiently.

Builders and general contractors can use 3D laser scanning to accurately capture existing site conditions, allowing for precise measurements and detailed 3D models, which helps to minimize errors, improve project planning, identify potential clashes, and ensure the construction project aligns perfectly with the design, ultimately leading to reduced rework and increased efficiency throughout the building process.

Point Clouds, As-Built Drawings & 3D BIM Models

Existing Conditions specializes in capturing 3D laser scan data and works to provide clients with intelligent deliverables to enhance the understanding of their site and informs decision-making at all levels.

These deliverables take on a variety of forms, but by far the most common is the initial form of raw data, the point cloud. By using state-of-the-art Leica laser scanners, Existing Conditions collects site data in individual points and creates a point cloud. Existing Conditions then takes these point clouds and produces custom deliverables for a project. Deliverables such as 3D BIM models, 2D CAD drawings, and more are created of the site detailing structural, architectural, and MEP features.

Using just the point cloud data, builders and general contractors can easily view infrastructure, potential conflicts, and more. And a full 3D model provides even more benefits, including the ability to do a virtual walk-through of the entire site.

Existing Conditions 3D Laser Scanning offers an opportunity for builders and general contractors to rework outdated plans to negate the inherent risks, inferences and clashes before they happen. With Existing Conditions, these risks are mitigated, as we provide 2-4 mm accurate data and complete scans of entire sites. Using the deliverables mentioned above, Existing Conditions helps contractors take control of the project site by avoiding costly change orders and delays.

Here are some of the ways builders and general contractors benefit from 3D laser scan technology:

• Accurate Information: Provide stakeholders with accurate, up-to-date information throughout a project and give them a chance to adjust their plans before expensive work begins.
• Visualization: Get a visual of the final result before construction even begins and make more informed decisions as you go.
• Communication: A digital footprint of a project makes communication and collaboration much more efficient. Projects and plans can be reviewed remotely, from anywhere in the world.
• Safety: With laser scanning and BIM, you can spot hazards or construction vulnerabilities without ever stepping on site. Fewer site visits also mean helping to safeguard clients from on-site hazards.
