Dimensional Control & Reverse Engineering Services

Capnor has a prefab dimensional control team that verifies prefabricated elements and installations, especially for facilities where extreme accuracy is required due to hazardous environment or limited time for assembly on site (e.g. offshore facilities).

Prefab dimensional control should be executed at all stages of manufacturing and reverse engineering:

• Production
• Final acceptance
• Dispatch

The scope of our services includes (but is not limited to):

• Stake outs on site and during prefabrication
• Fitting checking and as-built measurement
• CAD-based 3D inspection
• Reverse engineering services
• Plane defining and flatness check
• Dimensional control survey services
• 3D reverse engineering services
• Reverse engineering scanning services
• Detail engineering services

Dimensional Control - Benefits:

• Limitation of on-site activities by maximizing off-site activities (reduction of construction schedule and cost)
• Elimination of re-work (maximizing work efficiency) 
• Reduction of assembly time (minimizing offshore welding and fitting)
• Minimizing shutdown durations (earlier project completion)
• No surprises (risk mitigation)

Dimensional Control - Typical applications:

• Pipe spools
• Valves
• Fabricated assemblies
• Packaged equipment such as pump skids
• Christmas trees and associated equipment
• Tunnels, roads, bridges
• Stadiums, buildings
• Reverse engineering

Reverse Engineering Services - production and final acceptance

Dimensional control should be performed at all production stages to identify deviations in angle or geometry of the already fabricated elements. Partial inspection mitigates the risk of costly re-work and fabrication time extension.  

Once an item is fabricated, final quality inspection is performed. After measurements, all critical dims can be checked against the fabrication tolerances and drawings. By inspecting the finished article in 3D it is easy to measure in 3 dimensions across an object no matter where the datum is calculated from. It provides a permanent 3D record that cannot be disputed. 

Dimensional Control Maintenance

3D laser scanning along with total station measurements are used in a number of cases to identify damage or deformation across fabricated and installed elements at levels of details not possible to achieve with traditional methods. This accuracy combined with the visual 3D nature of the results makes it ideally suited for maintenance application. 

Our professional control team is ready to assure our clients that there are no issues related to quality and geometry of fabricated elements. Our team immediately:

• reaches the place
• compares dimension and geometry of fabricated elements vs. detailed drawings 
• solves the problem

Dimensional control survey services - Deliverables:

• inspection report
• CAD documentation
