Barwon Water is seeking to appoint a suitably qualified and experienced Principal Contractor for the supply and construction of approximately 5km (Sections 19,20,21 & 25i (Stage 1) and 23 (Stage 2)) of the Colac Pipeline Upgrade and all associated works. The majority of these works occur in the Great Otway National Park, with some works in the Otway State Forest and Colac Otway Shire road reserve. Minimisation of environmental impact and vegetation removal is critical to this project throughout construction. To aid this, works are to be contained within a constrained corridor with extensive use of no-go zones for protection. All construction is to be via open-cut and fill with trench widths to be minimised while still meeting the appropriate standards. Battering/benching will only be acceptable in areas where there is no impact to vegetation or incursion into Tree Protection Zones. There are Cultural Heritage aspects associated with this project, with details outlined in the Cultural Heritage Management Plan.

The proposed staging of this project sees Stage 1 (Sections 19,20,21&25i) constructed in the 2021/22 financial year, with Stage 2 (Section 23) to occur in the 2022/23 financial year. Due the climatic nature of the Otways, it is expected construction activities will occur during the drier months of the year.

It is a condition of Tender that Tenderers attend a Compulsory Site Inspection commencing 10.00 AM on 30 September 2021, held at the corner of Colac Pipeline track and Barongarook Rd, Barongarook. Due to the nature of the project site and COVID-19 risk management, each tenderer will be limited to one representative. To further reduce risk through minimising exposure, product suppliers will not be invited to attend. As always, suppliers can be provided the list of tenderers who attended the site visit upon request to enable them to make contact to tenderers directly to offer their product support. Further details are in the Tender Document, Clause 3.2
