Blue Rock Switchboard Electrical Upgrades

Southern Rural Water invites the Tenderer to submit a Tender for Blue Rock Switchboard Electrical Upgrades. Blue Rock Electrical Switchboard Upgrade Project consists of works to 3 switchboards. The main switchboard in the pump shed was installed approximately 40 years ago, it has now reached the end of its serviceable life and no longer meets AS/NZS 3000 (Wiring Rules) requirements for protection, isolation, and worker safety. The switchboard contains multiple redundant and energised cables from equipment that has long since been removed. The tower switchboard - of similar age and condition - faces the same issues. Degraded structure, non-compliant protection arrangements, and outdated wiring practices create an unsafe environment for routine inspection. The cone valve control cabinet presents an additional and significant safety concern. The cabinet currently houses 415V electrical components in the same enclosure as the hydraulic control system, forcing staff and contractors to work in close proximity to high voltage equipment during normal valve operations. Over time, the cabinet has undergone multiple modifications—including the integration of Pacific Energy's generator controls—creating a nonstandard, congested, and increasingly difficult-to-maintain arrangement. Ageing components are now prone to failure, and a malfunction in this cabinet could lead to prolonged outages or require unsafe manual interventions to restore valve control. Tenderers to note - if site visit / tender briefing session apply AND registration is required, registrations must be received by cut-off time as outlined in Tender Particulars to the Tender Officer. SRW advises tenderers not to use hyperlinks in their submissions to access various documents. Tenderers should provide the documents separately as SRW will not access any documents through hyperlinks.
