Digital validation: started early is much gained

As a specialist in the integral and multidisciplinary design and realization of innovative applications, Soltegro contributes strongly to a sustainable and vital infrastructure. One of the services the company provides is digital validation. A discipline that fits seamlessly into the current digitalization trend and offers the possibility to initiate verification and validation processes earlier during the realization phase of a project. And that yields the necessary profit. Also within the GWW sector.

During the realization of (infrastructure) construction projects, the necessary flows of information circulate from various corners. However, structuring and processing this information often causes problems in practice. The data often contradict each other, versions are not properly maintained and the available information is often too fragmented for efficient use. An undesirable situation, especially for the various stakeholders who need clear and high-quality project information. Especially when it comes to demonstrating the formulated project requirements. "It is precisely in that context that two things usually come into play," says Sjors Both, project manager within Soltegro. "First, the various testing processes normally lag behind the actual realization, as it were. In addition, in many cases there is too little time for the intended verification because of delays that occurred earlier in the chain."

Clutch

Soltegro's digital concept provides a welcome solution for this. "It is important to determine as early as possible in the construction process whether the delivery of the object meets both the set requirements and the customer's wishes," Both continues. "Simply because then you can tackle certain imperfections better and cheaper. In addition, you can use the object faster after delivery because the often lengthy test period can be shortened. It is precisely in these areas that our solution provides an effective tool. By linking the designs and the systems under development with a simulated environment, the functional requirements imposed on the design and the software can be verified at an early stage. And that not only results in a solid reduction of failure costs. It also prevents unnecessary lengthening of the chain and avoids sky-high fines due to late delivery."

Satisfied stakeholders

By adding a virtual 3D world to the simulated environment, Soltegro also provides visually attractive and more concrete information: the basis for optimal stakeholder management. "With Soltegro's concept, testing can start earlier in the chain, well before the actual realization is a reality," Both said. "At the same time, the layers of automation ensure that the overall testing time can also be further reduced. This is because the simulated field and 3D world do not have to be built from scratch, but are further developments of the existing functional design and BIM information. In this way, digital validation and verification also helps ensure that information is not fragmented even more."    

Digital validation in practice A16 Rotterdam 

During the detailed design phase of the A16, the functional behavior of each installation was worked out and linked to the tunnel's actual control system. From then on, the tunnel was digitally testable, verifiable and validatable. In the execution design phase, this link was used to conduct all system tests early on. Before any shovel went into the ground, every system was fully digitally tested, verified and validated. 

A9 Badhoevedorp-Holendrecht 

The A9 between Badhoevedorp and Holendrecht is being widened and deepened in several phases. Based on BIM information in combination with its own camera plan validator, Soltegro visualized the entire route in a short period of time. Subsequently, the positions and presets of all cameras mounted during the various construction phases and the final situation were digitally validated. This ensures visibility of the road during and after construction, which has resulted in reduced costs.
