The Task and Our Role
The Gateway Inn is an expansion to the Wests Group Mayfield hub.  The eight storey hotel includes 76 rooms and suites, multiple function rooms, a top floor restaurant and bar, and car park.  It shares the site with Wests Mayfield registered club and Balance Health Club.

The new hotel is part of a process that is changing the feel and image of Mayfield.  The area is transitioning from an industry oriented area, dominated by the steelworks, to a convenient and accessible location on the main transport corridor into Newcastle.

Beneath the site are deep, relatively compressible estuarine soils.  We were required to design an innovative pile raft solution to reduce costs and improve structural efficiency.  The implementation of this system eliminated the need for deep and costly piles to bedrock. 

Finite Element Analysis and Modelling was used to determine expected settlements and differential settlements of the pile raft.
