Projects

Highway Design

Detailed planning for safe roadways.

Flexible Pavement Design for Low-Volume Rural Road

• Designed a flexible pavement system using Austroads mechanistic-empirical design methodology

• Analysed traffic loading (ESA), subgrade strength (CBR), and drainage conditions

• Proposed layered pavement composition including sub-base, basecourse, and chip seal surfacing

• Optimised pavement thickness to achieve cost-effective design with improved resistance to rutting and fatigue cracking

Traffic Engineering Analysis of Urban Signalised Intersection

• Conducted traffic volume surveys and peak-hour flow analysis for a multi-leg urban intersection

• Assessed Level of Service (LOS), delays, and queue lengths using traffic engineering principles and SIDRA-based approach

• Developed solutions including signal timing optimisation, lane reconfiguration, and dedicated turning phases

• Achieved improved intersection efficiency and reduced congestion during peak periods

Contract Management Study – Road Maintenance (NZS 3910)

• Evaluated road maintenance contract framework based on NZS 3910

• Analysed contractor obligations, risk allocation, and KPI-based performance measures in a NZ context

• Prepared a risk register covering cost overruns, delays, and service level compliance

• Proposed monitoring and reporting mechanisms to improve contractor accountability and cost control

• Geometric Design of Rural State Highway Intersection

• Designed rural intersection improvements using Waka Kotahi NZ Transport Agency and Austroads guidelines

• Performed sight distance and heavy vehicle turning path analysis (WB-20)

• Proposed turn bays and geometric upgrades to improve safety and traffic flow
