Accurate monitoring, down to the millimetre, is crucial
A five-storey car park is being constructed under Garenmarkt, a square in the historic inner city of Leiden. Garenmarkt is surrounded by many buildings, including a listed monument right next to the excavation. For that reason, extremely accurate monitoring during construction is vital to prevent damage to surrounding structures. Iv-Infra will perform the monitoring, which will involve detecting and monitoring every millimetre of movement. In addition to elevation measurements, ground level monitoring and monitoring displacements in the soil strata, the noise and vibration levels resulting from the construction activities and the associated impacts on the surroundings will also be monitored.
