D.A.T. Digital Detection and Tracking during the renovation of the Galecopperbridge


For renovation of Galecopperbridge the Civil Engineering Department uses VolkerRail FlexInspect for digital detection and tracing of the works.

The Dutch Department of Waterways and Public Works (Rijkswaterstaat) has assigned the contract for renovation, strengthening and heightening the Galecopperbridge over the Amsterdam-Rhine Canal to the Galecom building company. The Galecopperbridge is located in the A12 close to the traffic junction Oudenrijn and is the second busiest bridge in the Netherlands. The busy Amsterdam-Rhine Canal is the only waterway between Amsterdam / the North of the Netherlands and the rivers Lek and Waal (Rotterdam and Germany) for inland shipping. The Galecopperbridge consists of two steel cable bridges, each of 5 lanes over the Amsterdam-Rhine Canal near the city of Utrecht. The bridge is 327 meters long. The bridge was opened in 1974 as part of the A12 motorway and replaced an arched bridge from 1936.

Various companies work together on this renovation including VolkerInfra, KWS Infra, Van Hattum and Blankevoort, VolkerRail, Vialis, Hollandia, Mercon, CT de Boer, Sarens and Feijenoord.


VolkerRail takes care of the welding of the metal (road) surface. 

The work should be carried out demonstrably within a controlled process. For this FlexInspect has been used. The reporting capability within FlexInspect offers many opportunities for the follow-up work and also for the demonstrability of operations.

Under the authority of the Civil Engineering Department of VolkerRail for the renovation and maintenance of steel bridges FlexInspect was designed in such a way that within this system the entire process can be performed demonstrably controlled. Especially for this, it was named D.A.T.: Digital Detection and Tracking.


The purpose of D.A.T. is a completely integrated delivery file. Integrated means that the repair proposals, quality controls, NDO examinations, quantities and progress monitoring are integrated into one single system and delivered in one single file.


By applying FlexInspect for D.A.T. this can be done within a single system and that makes putting together a completion file a simple action.

D.A.T. is used for:


  • digital verification of process steps from production of components up to the mounting in the construction
  • different checklists depending on the process
  • control in each process step with possibly photos and/or comments
  • real-time insight into the process through reports and graphs
  • traceability of the works performed, materials used and deployed personnel

How does this work for employees?

The damages to repair and the components to replace are read into the system. As soon as the repair or production work is started, the activities are captured in D.A.T. Subsequently, all controls required in the process are captured digitally. The back office has direct access to and insight in the reports.

The use of QR-codes

All damages/components receive a unique damage identification. Of each damage- or component-ID a QR-code is created. Damages outside on the bridge receive a sticker with a QR-code so that every employee understands what damage is the correct one. Also at entry into D.A.T. the QR-code is scanned so that all data are put in the right place.


QR-codes are also used to register and identify welders, quality inspectors and the materials used. QR-codes prevent typing and simplify the input of data for the employee outside.



Welding operations are incomparable. Many welding operations are executed in a short time and with use of progressive techniques. A lot of material knowledge was necessary to choose the right techniques. This has not gone by unnoticed: the magazine Welding Technics devoted an article to VolkerRail.
