GWH design and construct Mercure Newcastle Airport

IMG 0282
The Mercure Hotel Newcastle Airport is a design and construct development comprising of 95 accommodation rooms, restaurant, bar and conference and function facilities over four levels. The building consists of a steel frame and structural and non-structural precast concrete panels.
GWH designed and constructed the hotel from core specifications and it was built within 12 months from start to finish.
A key consideration in the design and construction of the project was the strict acoustic requirements imposed on the design due to its proximity to Williamtown RAAF base. One of the main challenges was formulating an internal framing and lining system that met the acoustic requirements but was at the same time cost effective and efficient to install.
Following an extensive tendering process a project specific technical manual was employed which utilised an acoustic framing system while minimising the number of layers of plasterboard required. The acoustic requirements also meant that a specialised glazing system was needed. After a lengthy tendering process a double and triple glazing system was manufactured locally and utilised in the build.
