    In a world of increasing population growth, urban density and their subsequent challenges Seamus’ vision is to create efficient and sustainable cities to inhabit. This passion motivates him to challenge concepts and methodologies to generate thoughtful and bespoke outcomes from multi-billion dollar infrastructure projects to localised issues. His approach is complemented through an enjoyment of managing and motivating large, complex stakeholder groups to deliver legacy outcomes as a collective team.

    His skill set has been developed through delivering, within key leadership and transport advisory technical roles, on projects such as Sydney Metro Northwest, Northconnex, Westconnex and Western Harbour Tunnel.  He is currently responsible for the management and delivery of a transport strategy (Station Link) to serve the needs of over 20,000 people per day following the closure of the Epping to Chatswood Railway on 30 September 2018. Seamus thrives on the challenge of delivering to budget and on time whilst exceeding client expectations. These objectives are achieved through a robust technical approach and developing a genuine connection with the client to understand the project’s relevant issues and core objectives from their perspective.
