Projects:
Duncan Brown Road Bridge, TRC
Lead structural / geotechnical design engineer for the 39m long, dual carriageway 3-span bridge. Bridge contains prestressed concrete deck units supported on a substructure of concrete piers and abutments supported by concrete bored piers.
Cairns Airport International T2 Upgrade
Lead structural design engineer for the International Terminal 2 upgrade. The upgrade includes various building extensions. The stiffened raft slab contained grids of integral band beam thickenings spanning between piles. Foundations were sub-contracted to a screw piling contractor.
Australian Border Force (ABF) Thursday Island Wharf Upgrade
As part of the ABF Fast Response Boat Program for Thursday Island, Leigh conducted site inspections, structural design for the Thursday Island wharf upgrade, and the analysis of geotechnical data for pavement design and maintenance facilities.
Cairns Bulk Sugar Terminal Pile Remediations
Lead structural designer and project/design manager for the Cairns Bulk Sugar Terminal Shed pile remediation works. Many of the sheds support piles has corroded reinforcement leading to compromised strength. Works included the identification of the compromised piles, and managing the works which included steel augmentation, the installation of sacrificial anodes and shotcreting to bring the piles back to acceptable strength.
Aurukun 1.2ML Reservoir
Lead structural and geotechnical design engineer for the 1.2ML reservoir in Aurukun to contain potable water for the Aurukun Community. The above ground tank included full precast walls, roof and internal columns locked in place by stainless steel anchoring systems.
Portal Concrete Drift End Piece Design
Structural and geotechnical design and detailing of the reinforced concrete portal concrete drift end pieces for Grosvenor Mine. Leigh’s role included the sizing, reinforcement detailing, and footings to withstand rock blast pressures from within the mine.
12-Level Highrise Development, Esplanade, Cairns
Geotechnical investigation for a proposed 12 level high-rise development to be constructed on the Cairns Esplanade for KNK Design Studios. Supervision, logging and coordination of three 25m deep boreholes with associated laboratory testing, geotechnical engineering analysis and geotechnical interpolation and reporting for deep foundations.
Harley Street Intersection Upgrade, Trunk Water Main Aerial Crossing, Kamerunga Water Main Aerial Crossing, Cairns
Geotechnical investigation for a proposed water trunk main aerial crossing in Kamerunga for FGF Developments. Geotechnical supervision, logging and coordination of borehole drilling for a water pipe aerial crossing to be supported by screw piles. Included geotechnical analysis, geotechnical interpolation and reporting for screw piles
