May 2026 – North East Link (Hoddle to Burke)

Dex Arounsavat served as Structural Design Manager with Seymour Whyte on the Hoddle to Burke Project, contributing from the project’s early inception stages (RFP-I and RFP-F) through to construction delivery.

Throughout the project lifecycle, Dex played a key role in the Urban Design and Landscape Plan (UDLP) and was instrumental in driving value engineering initiatives, achieving significant cost savings from the RFP-I phase. His responsibilities included cost planning, stakeholder engagement, compliance management, constructability reviews, and multidisciplinary coordination to ensure efficient and compliant project delivery.

Dex’s leadership and technical expertise ensured the successful integration of structural, architectural, and operational requirements across this complex infrastructure project.

The scope of the project included a diverse range of structural and civil infrastructure elements, including:

Bridges:

Yarra Shared Use Path (SUP) Bridge: A three-span space truss pedestrian bridge featuring architecturally distinctive Y-shaped tree piers.

Westbound Busway Bridge over Eastern Freeway at Chandler Highway: A two-span curved twin steel box girder bridge.

Chandler Highway Eastbound Exit Ramp Bridge: A single-span, heavily skewed and curved Super-T girder bridge.

Burke Road Eastbound Exit Ramp Bridge: A three-span curved twin steel box girder bridge.

Belford Road Bridge: Public Safety Barrier Upgrades

Existing Yarra River Bridges (both eastbound and westbound carriageways) – Barrier and Drainage Upgrades

Retaining Walls:

Architecturally treated walls designed to integrate with the surrounding environment.

Noise Walls:

Architectural plastic panel noise walls with concealed posts, ranging in height from 3 m to 8 m.

Signage and Intelligent Transport Systems (ITS) Structures:

Cantilever, Portal box and Truss gantries

Ancillary Infrastructure:

Off-structure barriers and miscellaneous elements including high mast lighting.

November 2023 – Coffs Harbour Bypass

Ferrovial Gamuda Joint Venture (FGJV) has been engaged to deliver the Coffs Harbour Bypass project, a major infrastructure development aimed at improving regional connectivity, enhancing transport efficiency, and increasing safety for motorists.

The project comprises approximately 14 km of dual carriageway, including 17 bridges, 2 interchanges, and 3 tunnels, along with associated buildings and ancillary structures. The bridge scope incorporates a range of structural systems, including integral precast plank bridges, multi-span Super-T girder bridges, and multi-span steel box pedestrian bridges spanning creeks, roads, and rail corridors. These structures are founded on a combination of pad footings, bored piles with pile caps, and monopiles.

Dex recently supported FGJV in delivering the Coffs Harbour Bypass project by contributing to value engineering initiatives in collaboration with both the construction and design teams. His role included undertaking detailed reviews of design packages to drive standardisation of structural elements, improve long-term maintenance outcomes for the client, and optimise material efficiency. This involved reducing structural steel quantities in buildings and reinforcement requirements in bridge structures, as well as implementing design refinements to enhance constructability and overall project delivery.
