Detailed Design for Public Drainage Assets, Lucknow

Project Location

The project is situated in the Lucknow area, extending across several key properties: 42 Lanes Road, Lucknow Recreation Reserve (64 Great Alpine Road), 60 Lanes Road, 237 Phillips Lane, 231 Phillips Lane, and 245 Princes Highway. Of these, the Lucknow Recreation Reserve (64 Great Alpine Road) and 245 Princes Highway (Drainage Reserve WLRB2) are owned by East Gippsland Shire Council.

The remaining properties will be subject to formal agreements, such as the creation of drainage easements and/or drainage reserves, or road reserves with provision for overland flow paths, as required to facilitate the works.

Where works are proposed within designated waterways, consultation and approval from the relevant Catchment Management Authority will be required prior to commencement. A location map is provided below to illustrate the full extent of the project area.

Scope of Services

The successful Consultant will be required to undertake and manage the process of delivering appropriate documentation suitable for the invitation for tenders for the upgrade works.

Consultant to deliver detailed design of assets WLRB 3a and outfall pipeline as shown on Drawings 2249/SWS/1 - 6 of Stormy Water Solutions, Lucknow PSP WLRB3a and Outfall Pipe – Functional Design Report, 9 September 2025 (CON2026 1754 – Attachment 3). Detailed design to align with Melbourne Water Wetland Design Manuals, refer appendix 2 in this documentation.

The scope includes, but is not limited to:

• Detailed Engineering feature survey with levels, identify utilities services.

• Undertake QL-B or QL-A service location if necessary.

• Service location and depthing. Provisional rates to be given for accurate depthing by potholing (optional) to ensure all conflicts are designed out and appropriate cover is adopted between existing services and new infrastructure.

• Detailed Geotechnical investigations geotechnical investigations within the proposed drainage reserve including permeability tests, ground water table information and salinity tests.

• Soil contamination investigation (in accordance with AS4482.2) within the proposed drainage reserve to determine any soil contamination issues and detail the soil type, amount of rock present and resultant impact in regard to construction of the drainage asset.

• Provisional rates to be given for site drainage investigations, catchment assessment and Hydraulic modelling to estimate peak flows for the minimum 1% AEP storm event;

• Under existing conditions
• Based on the catchment post-development scenario

• Water quality treatment computations and detailed design of WSUD components.

• Undertake all calculations necessary to identify the required sizes and scope of stormwater management assets for water quality and quantity to meet best practise requirements for this site and to protect the downstream environment.

• Preliminary plan for best value approach with layout plans, cross section drawings, Longitudinal sections and preliminary costings.
