3D Laser Scanning

For building construction projects that involve elements of virtual design or full BIM workflow's, Trimble 3D Laser Scanning solutions provide the following for both MEP and General Contractors:

• As built collection of existing conditions for renovation projects
• Progressive project data collection for QA/QC purposes
  (comparing model components to collected point cloud)

Trimble's 3D scanning solutions offer a range of options to satisfy your needs for vertical construction projects.

As-built Collection of Structural and MEP Components for Renovations

For MEP contractors involved in renovation projects, Trimble's 3D laser scanning solutions provide a cost effective and efficient method for gathering existing locations of mechanical systems.

Once scan data has been collected, Trimble's combination of point cloud modeling and mechanical detailing solutions allow MEP contractors the ability to work in a virtual design environment to understand existing conditions and design for the new build-out.

For general contractors, concrete contractors, and steel fabricators/erectors involved in renovation projects, Trimble's 3D laser scanning solutions provide a cost effective and efficient method for gathering existing locations of structural components.

Once scan data has been collected and fully registered into a usable point cloud, modeled structural components in Trimble RealWorks can be utilized as the basis for the creation of an architectural or structural model. This workflow allows contractors to work in a BIM environment using relevant data from the existing structure.

Progressive Project Scan Data Collection for Quality Control Purposes

In today's world of BIM projects that involve tight spatial and scheduling tolerances between various building systems, it is important for contractors to have tools that mitigate risk. Using Trimble's suite of 3D laser scanning solutions, Building Construction contractors can efficiently leverage the technology to verify what was intended in the model—to what has been constructed.

A few examples of these verification methods are as follows:

1. Laser scanning edge-of-slab after concrete pour—comparing point cloud to model
2. Assessing beam camber, comparing (point cloud to model) pre and post load data
3. Using Trimble RealWorks Floor Flatness routine, contractors can view concrete "peaks" and valleys in the point cloud—making the needed adjustments before interior framing
