The “Pelikaan” in Heemstede is a residential building complex situated in close proximity of the train track between Leiden and Haarlem. The complex consists of about 100 houses, 50 luxury villas and 50 apartments.
The acoustic consultant LBP|Sight carried out vibration measurements at several distances from the track. Based on the measurement results and Dutch standards it was decided to isolate the building 9dB at 16Hz. To comply with this demand, a vibration cut around 8 Hz is required.
For the vibration cut at 8 Hz a Stravibase SEB was designed using the material n°83. During construction the deflection of the vibration dampers was measured and checked.
