💧 Wungong Brook Water Monitoring - Byford Rail Extension Project

Contract awarded for Wungong Brook water monitoring for the Byford Rail Extension Project, ensuring environmental compliance post-construction.

The Byford Rail Extension (the ‘Proposal’) connects to the existing Armadale train line to Byford, located 8 km south of Armadale. The northern Section of the Proposal is within the City of Armadale; the southern Section is within the Shire of Serpentine – Jarrahdale. As part of the Proposal the existing Wungong Brook bridge was demolished and removed to allow for the construction of the new bridge which comprises of a new rail bridge and principal shared path (PSP) bridge. The Wungong Brook Management Plan (Public Transport Authority of Western Australia, 2023) (‘WBMP’) was developed in accordance with Condition 3-2 of the Ministerial Statement 1183 to ensure the hydrological regime of Wungong Brook is maintained during construction and operation of the proposal. The WBMP is to be implemented from commencement of ground disturbing activities and for at least twelve (12) months following the completion of construction of the new bridge, or until the Chief Executive Officer (CEO) of the Department of Water and Environmental Regulation (DWER) has confirmed by notice in writing. The WBMP includes trigger and threshold values for the management of direct and indirect impacts to Wungong Brook. Construction of the new Wungong Brook Bridge was completed in June 2025, with the first six (6) months of water monitoring being undertaken in-house by METconnx. This Procurement seeks to engage a suitably qualified team for the continuation of the groundwater and surface water monitoring at Wungong Brook for the remaining six (6) months required under the WBMP or until such time as the DWER CEO confirms in writing monitoring can cease.

The Public Transport Authority awarded a contract valued at an estimated $66,514 via Limited Sourcing to Envice (Envice Pty Ltd) for water monitoring services.
