Our record
Hutchison Weller takes pride in adding value to projects, small and large, demonstrating technical accomplishment, innovative service and a strong client focus. This is reflected in the successes we bring our clients.
This section includes examples of relevant recent projects that demonstrate these attributes.
Coffs Harbour Bypass
Hutchison Weller is the Independent Acoustic Advisor to the iconic Coffs Harbour Bypass project.
Covering around 14 kilometers on the western side of Coffs Harbour in NSW, this challenging project includes building three two-directional tunnels and more than 20 bridges.
As the Acoustic Advisor, we work with the contractor, Gamuda Ferrovial Joint Venture, Transport for NSW and the Department of Planning to make sure the project is built to manage the noise and vibration impacts from the project, considering practical prject needs balanced with community and Agency expectations.
Sydney Metro West
Hutchison Weller supports the ACCIONA Ferrovial JV in this critical infrastructure project, including noise and vibration assessment and management and regular noise and vibration monitoring. We provided KNOWnoise to the team for ancillary sites and tunnelling.
Western Harbour Tunnel
Hutchison Weller is providing Environmental Planning, Approval and Acoustic services to ACCIONA during delivery of the Western Harbour Tunnel - a twin tolled motorway tunnel linking the WestConnex at Rozelle to the Warringah Freeway at North Sydney. Over the course of the project, we have:
- delivered a modification to the EIS for an alternative construction method using a TBM rather than submerged tunnels;
- developed KNOWnoise™ for tunnelling (ground-borne noise) and surface works;
- designed ancillary sites including acoustic sheds and worked closely with the team on everyday environmental management.
WestConnex
Hutchison Weller acted as the Independent Environmental Representative (ER) and the Acoustic Advisor (AA) to the M4-M5 Link and Rozelle INterchanges stages of this state significant infrastructure project between 2018 and 2025. We facilitated compliance with project conditions and management of environmental impacts considering project, community and Agency expectations.
Central West Orana
Hutchison Weller has been assisting the ACCIONA, Cobra and Endeavour Energy (ACE) consortium with this major Renewable Energy Zone project in central western NSW since tender. The project involves construction of around 250 km of new 330kV and 500kV transmission lines and supporting energy hubs, switching stations and ancillary sites.
Hume Link East
Mulgoa Road Upgrade - Stages 1 and 2
Hutchison Weller is working with Seymour Whyte to deliver Stages 1 and 2 of the Mulgoad Road Upgrade Project in Western Sydney. The project involves widening the road corridor and upgrading intersections, including construction of noise walls.
Hutchison Weller has aided the project team since 2021, proving noise and vibration monitoring, construction and road traffic noise and vibration assessment, assisting in noise wall design and p[roviding KNOWnoise™ to improve construction assessment, scheduling and mitigation.
Inland Rail - Illabo to Stockinbingal
Hutchison Weller is working with John Holland on the 37 kilometer Illabo to Stockinbingal Section of the Inland Rail Project -
We are delivering noise and vibration services including management plan, impact assessment, operational road and rail noise impact assessment, and KNOWnoise™.
Stewardship Maintenance Contract: Western Sydney
Hutchison Weller was the environmental manager of the Stewardship Maintenance Contract, a major road network maintenance and upgrade program. The team provided environmental management as well as technical noise and vibration services to Downer over several years.
Northern Beaches hospital road upgrade
Hutchison Weller assisted Ferrovial with environmental management including variations to the Environment Protection Licence, modifications to approvals, development of construction noise and vibration management plan, noise and vibration monitoring and delivery of KNOWnoise™
NorthConnex
Hutchison Weller provided environmental management services to the Lend Lease Bouygues Joint venture, while building NorthConnex, a major road construction project in Sydney’s North.
Services include noise and vibration monitoring, impact assessment, preparation of management plans and consistency assessment reviews as well as providing KNOWnoise.
Batemans Bay Bridge replacement
Hutchison Weller assisted John Holland on this key regional project; having developed the project’s CNVMP and providing ongoing acoustic advice and monitoring. We also provided KNOWnoise for this sensitve project.
