JFC were awarded works of submain installation and associated civils and reinstatements across 15 streets by Christchurch City Council. 

Of note was the installation/renewal of 5670m of water supply sub-main involving major water reticulation works through variable ground conditions within Aranui and South New Brighton.

The council’s goal was to bring the submains up to the current standard as the existing ones were nearing the end of their economic life.

Scope of Works

• Mark and protect all existing services in the work area
• Supply and installation of watermains, bends, tees, couplers, fire hydrants, sluice valves, gate valves, thrust blocks, pipe protection slabs, etc. Bed and haunch pipes and backfill as per CSS
• Pressure test pipework to 1000 kPa and in conformance with required standards and specifications
• Connect newly laid pipes into the existing reticulation system
• Remove redundant valves and fittings as specified
• Chlorination and bacteriological testing of water pipes as per attached memo
• Reinstate all road, footpath and paved surfaces to the National Code of Practice for Utility Operators’ Access to Transport Corridors

This project involved a pro-active approach to our community impact, stakeholder engagement, environmental compliance, traffic, contract, quality, and H&S risk management, and a sound knowledge of CCC as a client.
