In addition to providing LED screens and AV technology, we are often called in as consultants due to our many years of experience. For the installation of a new LED cube in the Veltins Arena in Gelsenkirchen, we were commissioned to carry out a needs assessment on site and then prepare and accompany the tender. We reviewed and compared all offers and made a recommendation for the award of the contract. We supervised the project until the end with production control and monitoring as well as the final audit.
