Prefab dimensional control

Apply 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 during installation or limited time for assembly on site (e.g. offshore facilities).

Prefab dimensional control should be performed / executed at all level of manufacturing:
•    Production
•    Final acceptance
•    Dispatch

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
•    Plane defining and flatness checking

•    More meaningful and constructible design deliverables (no retrospective engineering)
•    Minimization of on-site activities by maximizing off-site activities (reduction to construction schedule and cost)
•    Elimination of re-work (maximize work efficiency)
•    Reduction of installation time (minimize offshore welding and fitting)
•    Minimization of shutdown durations (earlier project completion)
•    No surprises (risk mitigation)

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

Production and final acceptance

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

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 can't be disputed.

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

•    inspection report
•    CAD documentation


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 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 is no issues related to quality and geometry of installed objects. Our team:
•    reaches the place
•    compares dimension and geometry of installed objects vs detailed drawings
•    delivers inspection report

•    inspection report
•    3D model and drawings
