Drone-In-A-Box Surveys Track Leverkusen Bridge Build

The project involves the installation of a fixed ‘drone-in-a-box’ system at the site, enabling regular aerial surveys to be carried out without the need for on-site pilots. Operations are managed remotely from Skyports’ Remote Operation Centre in Madrid, Spain, where flights are conducted beyond visual line of sight (BVLOS).

The system performs weekly automated surveys, collecting data that is used to create a detailed, cumulative view of construction progress. This approach replaces earlier methods that relied largely on manual observation and occasional drone flights, which required personnel to be physically present and provided only limited insight.

Survey data is processed using DroneDeploy software to generate both 2D and 3D outputs. These models are used by HOCHTIEF to monitor site activity, track development against plans, and identify potential issues at an early stage. The availability of updated 3D models each week supports ongoing comparison between planned and actual progress, particularly in areas such as earthworks.

In a statement, Alex Brown, CEO, Skyports Drone Services, said: “Large infrastructure projects are incredibly intricate and complex, with construction companies under pressure to deliver on time and on budget.

“With automated ‘drone-in-a-box’ surveys like this we’re providing alternate perspectives and deep level data insights that can improve resource planning and catch any potential issues early, helping keep projects on track.

“Piloting the drone remotely also means we are creating operational efficiencies, improving cost and data outputs for our customers.”

The Rheinbrücke Leverkusen bridge project is scheduled for completion in 2028 and involves significant preparatory work, including the dismantling of the existing structure and construction across both banks of the river. The scale and complexity of the project require consistent and accurate monitoring to maintain timelines and budgets.

Klaus Grüttner, Executive Vice President Europe, HOCHTIEF Infrastructure, added: “By partnering with Skyports, we have a leading innovator in drone technology at our side to drive our complex construction projects. This cooperation enables us to monitor the construction progress seamlessly and cost-efficiently and to provide targeted support in billing, especially in earthworks. In addition, we benefit from precise surveying data that supports a continuous target/actual comparison and the optimisation of our construction processes.”
