3D Dimensional Inspection Services

High-accuracy laser tracker inspection for large-scale industrial components and assemblies.

DMS provides precision 3D inspection services to verify geometry, feature position and tolerance compliance across large industrial assets. Our inspection capability supports manufacturing, installation and shutdown environments where dimensional conformity is critical.

Inspection Applications

• Small, Medium & Large fabricated structures

• Jigs, Fixtures and Tools

• Turbine and generator components

• Machined assemblies

• Structural steel and frames

• Installed plant and equipment

• Modular assemblies prior to commissioning

Inspection Capability

Laser tracker measurement enables rapid capture of accurate 3D coordinate data over large working volumes.

Services include:

• CAD comparison and deviation analysis

• Feature position verification

• Geometric tolerance validation

• Bolt pattern and interface inspection

• Flatness, straightness and positional checks

• As-built documentation

Reporting & Documentation

Inspection results are delivered in structured reporting formats suitable for QA documentation and engineering validation.

• Colour deviation plots

• Tabulated feature reports

• PDF inspection summaries

• Raw coordinate data on request

• Traceable measurement records

Why Laser Tracker Inspection?

Compared with conventional inspection methods, 3D laser tracker inspection provides:

• Higher accuracy over large volumes

• Reduced setup time

• Digital traceability

• Immediate deviation feedback

• Reduced rework risk

Technical Specifications

1. Working range up to 160 metres

2. Point accuracy to 0.015 mm

3. Real-time coordinate capture

4. Portable on-site capability

Measured features are evaluated against nominal CAD geometry or engineering drawings. Reports detail nominal values, measured coordinates and computed deviations, with tolerance criteria applied to determine conformity.

CAD Model Comparison & Graphical Inspection Reports

Measured data is aligned to the nominal 3D CAD model to enable full geometric comparison. Results are delivered as graphical inspection reports incorporating colour deviation mapping and tolerance-based feature evaluation.

This method provides the highest level of inspection clarity when validated CAD data is available.

GD&T Inspection

Components can be inspected against Geometric Dimensioning and Tolerancing (GD&T) specifications to validate form, position, orientation and profile.

Embedded 3D GD&T data can be imported directly for automated evaluation. Where tolerances exist only on 2D drawings, they are applied within the inspection software to ensure accurate conformity assessment.

Rich Graphical Reporting

Inspection results are delivered in structured reports tailored to project requirements, from tabulated measurement summaries to detailed graphical reports with 3D CAD views and deviation analysis.
