Capella WTP - Installation of Emergency Generator and Associated Civil Works & Switchboard

⁠⁠⁠Central Highlands Regional Council (CHRC) is undertaking upgrades at the Capella Water Treatment Plant (WTP) to improve the reliability and resilience of critical infrastructure supporting water supply to the local community. These works form part of CHRC’s broader program to enhance operational continuity, particularly during power outages and peak demand conditions.

The upgrade works include the integration of standby power systems and associated civil and electrical infrastructure to enable automatic operation during loss of mains power. This includes installation and integration of a plant emergency generator, connection and testing of new Automatic Transfer Switch (ATS), and supporting electrical distribution systems to ensure seamless operation of key treatment processes.

In addition to generator integration works, the project includes installation of conduits, cabling, and cable pits to connect the ultrafiltration (UF) plant and generator systems to the existing Main Switchboard (MSB), ensuring full operational integration of the treatment plant.

The Contractor will be responsible for the design of a generator shade structure, as well as the construction of associated civil works including concrete slabs and site surfacing.

No formal design will be provided for the 10,000L fuel pod slab or the two additional concrete slabs required by CHRC. The Contractor shall construct the slabs to match the design intent of the generator slab and the slab between the existing access way and existing shed, including but not limited to slab thickness, concrete class, reinforcement details, subgrade preparation, and surface finish, ensuring suitability for the intended loading and operational requirements.

Works relating to Ergon network cabling, supply connections, and modifications to the existing metering panel are excluded from this RFT and are being undertaken under a separate contract. Notwithstanding this, the Contractor shall be responsible for liaising and coordinating with Ergon Energy to facilitate energization of the new metering panel and electrical system, and to ensure commissioning activities are completed without delay.

All works are subject to CHRC approval, and no construction activities shall commence until formal authorization has been provided.

Scope of Work

The works covered under this Request for Tender (RFT) include the design, supply, and construction of civil, structural, and electrical infrastructure associated with generator and switchboard installations at the Capella Water Treatment Plant (WTP).

The Contractor shall provide all labour, materials, plant, equipment, supervision, and associated services necessary to complete the works in accordance with the Contract requirements.
