RESA 025 (AUD 100 million)— Sydney Airport, NSW
Bridge Engineer
The project was the Winner of Engineers Australia – Engineering Excellence 2010 – Sydney Division Infrastructure Projects
The Runway End Safety Area – Runway 025 (RESA 025) project spans the M5 East Tunnel and Sydneys largest sewer culvert (SWSOOS), the RESA was constructed on a series of landbridges making it Australia’s first suspended concrete RESA deck. The deck is 8,100 m2 on raked concrete designed to enhance aircraft deceleration and to support emergency vehicles. Josh was involved in many aspects of the RESA structural design including:
SWSOOS Landbridge – The SWSOOS Landbridge is three simply supported precast prestressed plank bridge spans within the Runway End Safety Area (RESA) at Sydney Airport. Design Loads were based on the emergency landing of an A380-Freight aeroplane, Nose gear loads of 1,245kN ultimate. Design Software utilised included LUSAS, SAM and SpaceGass. Josh was involved in the design of precast prestressed girders for three precast plank bridge spans. Design of deck slabs.
Perimeter Road Bridge – Design of precast prestressed girders and deck slab.
M5 East Retaining Walls – Design of Cast in-situ cantilevered retaining walls over the M5 East Motorway at Sydney Airport.
SWSOOS Headstock – The existing SWSOOS headstock was damaged through the course of construction activity on site. Advanced FEA analysis in LUSAS involving contact boundary conditions was conducted to develop an external post tensioned solution invloving steel brackets clamped either end of the headstock with stress bars.
SWSOOS Downturn Beam – The downturn beam supporting the SWSOOS itself inturn supported on roller bearings was overloaded during the course of construction causing damage to the ends of the beam. FEA modelling using LUSAS was conducted incorporating thick shell elements and contact surfaces to gauge the design actions. A strengthening solution was then designed to rehabilitate the beam.
Various – Structural checks and verifications on Super-T girders, Construction Stage crane and temporary loading, Site Inspections, Dilapidation Survey and Report of the Heritage Listed SWSOOS

Client: Novo Rail
Station Road Overbridge (AUD 10 million)— Auburn, NSW
Bridge Engineer
As one of only 2 accesses to Auburn over the railway line, the old Auburn Station Road Bridge needed to be replaced with a combined 4-lane road and 2-way pedestrian walkway and dedicated services route. The single 31 m span steel composite trough girder bridge replaced an existing two span two lane bridge. The heaviest of girder unit weighed just less than 100 tonne and comprised steel trough girders onto which a concrete deck slab had previously been constructed. The remaining girders, comprising only the steel trough units were placed in a separate weekend track possession, and the deck slab was cast in situ. A crucial portion of the design and verification was to ensure final girder deflections of the propped and un-propped girders were equal. Josh was responsible for:
– Structural verification of the 31 m single span four traffic lane bridge, with two pedestrian walkways. The bridge is designed as eight steel trough girders with a composite concrete deck slab. The analysis for structural verification was conducted in LUSAS Bridge Plus.
– Structural design of two 31 metre long, 3 metre high timber hoardings along the edges of the girders to enable pedestrian access during the construction along the initially erected girders.

– Structural design of a temporary piling rig platform and timber retaining wall to allow access for a 30 tonne piling rig to conduct piling of the abutments at Station Road Overbridge.
