UINZ were engaged by CCC to replace 4.3km of DN63 submain in Aranui, Somerfield and Sydenham Areas. This project ran for 11 months including a short break for Covid 19 lockdown. This project was completed with a 50% share of the workload between UINZ crews and one subcontractor, Brent Cook. It was finished to a high standard, which was noted by the client on final walkover.
UINZ went into this project as a joint venture with Isaacs Construction repairing damaged sections of underground infrastructure from the Kaikoura Earthquake and also a large water-main replacement along the Esplanade.
UINZ were awarded 670m of DN150 SCH40 fuel pipe line on behalf of MOBIL OIL NZ to replace an existing DN100 section of pipeline. The pipeline extended up the Bridle path road to a tie location above the tunnel entrance on Tunnel road. The tie in location on the downstream is located beside station road after the Heathcote valley school.
The pipeline has not be renewed since the 1960s. With a lot of emphases on safety and quality, UINZ worked in closure with Mobil , McConnel Dowell and Taurus engineering. This allowed UINZ to install the DN150 pipe with minimal disruption to the area and at a high quality finish and performing at a very high safety standard.
UINZ had been asked to complete watermain upgrades on Westminster St and Dee St, St Albans.
This job was increased to several water main relocations in surrounding streets to accommodate new SW water being laid by others.
The project went well and was finished on budget and all final connections completed during the night to accommodate location Businesses.
We used both trenching and trenchless technology to complete the works which minimised disruption and road closures.

UINZ were awarded the 1.5km DN250 watermain renewal by Christchurch city council by lowest confirming tender, UINZ completed the entire pipeline using our in house trenchless technology completing the project with minimal disruption to the local area and completing the project 2 weeks ahead on programme. UINZ also offered ECI to this project 12 month prior to it being disrupted for tender.
With never worked with HRS before UINZ tendered to complete all the drainage and underground service for the new KiwiRail service centre and was successful with working closely around the design and costs to complete.
With Isaac’s Being awarded the new road construction of cranford street, a new 1.3km watermain was to be installed in which UINZ were approach to install Via Directional drilling the job also included 20 major shutdowns and connections to the ex. Network.
The final piece of the waste water wider project taking the waste water from the Lyttleton bays to the Christchurch main treatment plan in Bromley UINZ were nominated to complete the 4.5km pipeline from the tunnel to the main pump station in ferry road, this project was a huge design challenge with having all types of installation methods to install the pipeline.
Since the start of the Christchurch Northern Corridor starting UINZ has been completing works for the alliance and were awarded the 3 waters package the involved 300m of DN355 booster main for water and new pressure main crossing the newly worked motorway.
On the back of WWP2 being a huge success UINZ were nominated to complete the civil works for FHCS on WWP3 with 70% of the project having to be completed at night this made things tricky for unknown interruptions, the project consisted of upgrades to 3 ex. Pump stations and a new pump station at simion quay near the tunnel.
Part the earthquake recovery plan in Kaikoura UINZ were awarded the Telco ducting project that ran through the north side of Kaikoura upgrading the ducting for the fibre network feeding the town ship this duct was approx. 7km long and through approx. 4km of rock in the road carriage.
UINZ’s first WW treatment plant project fell with in our recently form joint venture between, Isaac’s Construction and ARC Projects, our JV was awarded the $2.6million upgrade project in which UINZ completed all the PipeWorks and large connection on the project.
With our recent success on projects with civil south we were contracted in to complete all underground services works on the new upgrade to the Fonterra plant in darfield which consisted of large-scale stormwater and power ducting.
UINZ were awarded the Darfield watermain renewals with 2 parts of the project both the bulk watermain feeding the town ship and the submain feeding some rural properties this works consisted on a pipe ramming under SH76
The Perymans Bridge had developed a large leak over the years of movement with an internal pipe, SDC decided to reinstate the PipeWorks to the outside of the bridge in which UINZ were contracted by Sicon to complete the works, UINZ completed both the design and construction of the pipe crossing using specialised brackets and custom made Galv dipped DN200 pipe.
Southbridge had just been issued a new water well with the requirement of a new booster main to the old town of southbridge UINZ were contracted into directional drill in DN250 PE for approx. 400m from the new pumping station to the town centre.
Part of the well head packages through Christchurch city council FHCS was awarded prestons pump station which included 300mm of DN250 PE and new valve chambers UINZ was subbed in by FHCS to complete all physical works on the project in which our drill team installed all ducting and PipeWorks.
With success in the quarryman’s cycleway stage 1A with Isaac’s construction UINZ were nominated to complete the similar build on the sparks/Henderson intersection installing a 4-way DI water system for the intersection upgrade. UINZ also completed all the traffic light ducting and Orion ducting Via Directional Drilling.
Part of WWP2 UINZ were awarded additional works to install 2 x steel casings under the main port railway in a 36 hour window which we structured 80% of staff to work 24hrs a day in 12 hour shifts with careful planning and hard work from our teams we completed this in 30 hours, 6 hours earlier than expected.
With the old PVC pumping main from Tai Tapu to halswell starting to cause some problems UINZ were awarded a 1.2km renewal package as part of the Selwyn District council upgrade scheme all works were complete by our trenchless team with minimal disruption to the traffic.
