The surveying, monitoring and environmental advice and research on and around the road widening and sunken construction of the A9 between Badhoevedorp and Holendrecht is provided by Geonius. With engineers, consultants and technicians in the field, Geonius can operate efficiently and flexibly. By being involved at an early stage of a project, a lot can be foreseen and if unexpected situations do arise, they can switch quickly.
Back in 2019, initial contact was made between construction consortium VeenIX, which is carrying out the work on the A9 on behalf of Rijkswaterstaat, and Geonius. "On the basis of an existing environmental soil survey, we issued an environmental advice at the time," says Niels Geuijen, Environmental Project Manager at Geonius. "That was the reason we were allowed to perform more detailed research in the next design phase. And we actually still do that when things come up in the design and construction that we don't have information about. So on the one hand we are consultants, but at the same time we also perform all the soil investigations and supervise the soil remediation of mainly highway-related contamination. And we also do that for other material streams that are released."
From the dimensioning discipline, Geonius is active on the project with just under twenty employees. "Everything that needs to be measured and plotted within the project boundary goes through us," says Hassan El Gardaoui, project manager of dimensioning from Geonius. "It ranges from surveying data and setting up a primary surveying base to measuring concrete and asphalt work and surveying data for cables and pipes. We also monitor (temporary) structures, sheet piling, sand bodies and other objects for settlement behavior. It is true that Geonius is now involved in the A9 project with two disciplines, but our scope is much broader with fields such as Landscape, Archaeology and Ecology. With this broad expertise in the background as well as our own field workers, we can respond quickly and flexibly to virtually any challenge."
