Zala County Hospital Szent Rafael Zalaegerszeg, HU Case Study Property Owner OVERVIEW Zala County Hospital In order to provide a faster emergency response time Main Contractor for South Eastern Hungary, the Zala County Hospital ZÁÉV compound was equipped with a helicopter landing pad on top of the new paediatric building. Architect Zala-Art (István Czigány) Acoustic Consultant Gusztáv Józsa Stravifloor Prefab • Pre-manufactured modular floating floor solution. • Excellent structure-borne and airborne noise isolation thanks to the elastomeric bearings or springs. SOLUTION To isolate the landing pad from the rest of the building a high performance floating slab system, Stravifloor Prefab, was designed to take a permanent load of up to 500 kg/m² plus an occasional temporary load for 1 helicopter of 400 kg/m². Particular attention had to be paid to practical considerations such as drainage and thermal insulation of the building. Consequently, the slab was constructed with a horizontal bottom but with a slight incline on top to ensure no standing water was present on the landing pad. In addition, a thermal insulation layer was also installed in the air void which had to stay uncompressed even when the slab was already loaded in order not to influence the calculated performance of the floating floor. AT A GLANCE CHALLENGES • During take-off and landing, helicopters produce a lot of noise and vibration that can interfere with sensitive medical equipment and disturb both patients and medical staff BENEFITS • Transmission of structure-borne noise towards the rest of the building is significantly reduced • Quick and easy installation REUTENBEEK 9-11, 3090 OVERIJSE, BELGIUM T +32 2 687 79 07 / F +32 2 687 35 52 [email protected] / WWW.CDM-STRAVITEC.COM.
