Dimensional control verification of an industrial structure

Dimensional Control & QA/QC Services

Verify construction accuracy against design models using 3D scan data. Detect deviations early, before they become expensive.

Overview

Dimensional control compares what has been built against what was designed — while there is still time to correct it. By scanning completed work and analysing it against the design model, we detect out-of-tolerance elements within days of construction, not months later during fit-out or equipment installation.

The economics are simple: a misaligned steel connection found at erection costs a fraction of one found when modules arrive on site. For fabrication yards, EPC contractors, and owners in Nigeria, scan-based verification has become standard practice on high-value builds.

We deliver colour-mapped deviation reports that make problems immediately visible, along with dimensional data your engineers can use to disposition each deviation — accept, adapt, or rework.

What's Included

  • Construction verification scanning at defined milestones
  • Colour-mapped deviation analysis against design models
  • Steel, concrete, and module fabrication verification
  • Progress monitoring across construction phases
  • Flatness, plumbness, and alignment reporting
  • Pre-assembly fit-up verification for modular construction

Dimensional Control — Frequently Asked Questions

What tolerances can scan-based dimensional control verify?
With ±2mm scan accuracy, we reliably verify structural tolerances of ±5mm and coarser — covering steel erection, concrete works, embedded plates, and module fabrication checks specified in most construction standards.
At what construction stages should verification scans happen?
Typical milestones are foundation and anchor bolt verification, structural steel erection, floor slab flatness, and pre-installation checks before major equipment or modules arrive. We help you build scanning into the project quality plan.
How quickly are deviation reports delivered?
For milestone verifications, colour-mapped deviation reports are typically delivered within 48–72 hours of the site scan, fast enough to act before the next construction activity covers up the work.
