3D Laser-Scanning

Preparation

Site conditions and project goals are reviewed to plan complete, efficient scan coverage before work begins.

Every scanning project starts with a clear understanding of what needs to be captured and why. TWG reviews your project goals, existing documentation, and site conditions before deployment — so the scanning plan covers every area your team needs in as few visits as possible. Good preparation means complete data.

We also discuss deliverable formats upfront — whether your team needs a point cloud, a coordinated Revit model, a full CAD drawing set, or a combination of all three. Knowing the end goal before scanning begins means the data is captured in a way that translates directly into the deliverables your project actually requires.

What preparation includes:

• Review of project goals, scope, and existing documentation
• Site assessment to plan complete scan coverage and equipment positioning
• Discussion of deliverable formats and file requirements
• Coordination around site access, operational schedules, and any environmental constraints
• Scan plan development to ensure complete, efficient data capture in as few visits as possible

Scanning

TWG deploys the Leica RTC360 on-site to capture precise existing conditions across your entire project area.

The Leica RTC360 captures up to two million data points per second — documenting walls, ceilings, structural elements, equipment, and every surface in between with a level of accuracy that manual measurement simply can’t match. Depending on the size and complexity of the facility, scanning may be completed in a single day or across multiple visits — whatever the project requires to capture complete, accurate data without disrupting ongoing operations.

What gets captured:

• Complete interior and exterior building geometry
• Structural elements — columns, beams, walls, and slabs
• Mechanical, process, and industrial equipment in three dimensions
• Ceiling heights, floor levels, and overall building envelope
• Site conditions and surrounding context where required

Processing

Scan data is registered, refined, and built into coordinated models and drawings your team can work from.

Raw point cloud data is registered — meaning all individual scan positions are aligned and merged into a single, cohesive three-dimensional record of the site. TWG then processes that data into the deliverable format your project requires — whether that’s a clean point cloud, a coordinated Revit model, or a full set of CAD drawings. The result reflects the building exactly as it exists, not as it was originally documented.

Processing deliverables include:

• Registered point cloud data in industry-standard formats
• Coordinated Revit models built directly from scan data
• 2D CAD drawings — floor plans, elevations, sections, and reflected ceiling plans
• As-built floor plans for facility management and documentation
• Industrial facility documentation — pipe routing, equipment layouts, and structural records

Report

Your team receives clean, organized deliverables in the formats you use — with clear communication throughout.

Every TWG project concludes with a complete deliverable package tailored to your project’s specific needs. Files are organized, clearly labeled, and delivered in the formats your design team, engineering firm, or contractor works in. TWG stays in communication throughout the process — so you always know where your project stands and what’s coming next.

Final deliverables typically include:

• Point cloud data files compatible with Autodesk ReCap, Revit, and AutoCAD
• Coordinated Revit models and BIM documentation
• CAD drawing sets in the formats your team uses
• Scan reference sheets and project documentation
