Residential Builds
Building and Renovating
Building your dream home can be both exciting and daunting.
We can help, we listen to understand your vision, then supply and implement solutions, working with you from consultancy to handover.
Optum’s unique consultation and planning services can help you maximise the design and operating efficiency of your home.
Our team takes great pride in delivering quality client experiences in creating healthy, comfortable homes for families to enjoy.
Plumbing
Your new home or renovation will require water and waste pipework for bathroom, kitchen and laundry. Plumbing is installed in three main stages; pre-slab, pre-line and fit off. Pre-slab refers to the pipework laid beneath the slab. Pre-line is the pipework brought up through the walls. Fit off is the installation of your front of wall fixtures and fittings.
Stage 1 – Pre-slab: after foundations, prior to slab being poured
Stage 2 – Pre-line: after roof is installed, prior to insulation installation
Stage 3 – Fit off: after painting and flooring is finished
Each stage of your plumbing will require a council inspection, which we will organise on your behalf. Central heating pipework and fittings are installed at the same time as the plumbing stages.
Gas Fitting
Gas fitting in your new home requires installation of pipework, and appliance installations for water heating, room heating and cooking, gas fire and gas hobs.
Stage 2 – Pre-line: after roof is installed, prior to insulation installation
Stage 3 – Fit off: after painting and flooring is finished
Council requires a gas certificate to be submitted with your code of compliance, which we supply as part of your final documentation.
Most properties in Wanaka and Queenstown have LPG bottles rather than natural reticulated mains gas. We install an external gas bottle station with 2 x 45kg bottles.
The gas bottle station must be installed on a concrete pad on flat ground, away from windows and any sources of ignition such as external water heaters.
Reticulated mains gas is only available in newer subdivisions. The homeowner liaises directly with the mains gas provider to get a meter installed by an appointed third party.
Drain Laying & Mains Water
Drain laying refers to underground external wastewater pipework, water mains, stormwater pipework, soak pits, sumps, downpipes and channel drains.
Stage 1 or 3: Drainage is preferably done after the slab is poured and prior to scaffolding going up. If this isn’t possible, the drainage will be done at the end of the project, before landscaping starts.
External drainage requires a council inspection, which we organise on your behalf. Council requires a drainage plan to be submitted with your code of compliance, which we supply as part of your final documentation.
Off Mains Solutions
We assist with off-mains solutions for semi-rural or rural properties, including water pumps, water tanks for rainwater or fire fighting, onsite wastewater treatment and disposal, and irrigation dripper fields.
Stage 1 or 3: Usually coordinated with other digger work, as excavation is required.
An electrician must be engaged for pump installations.
A wastewater engineer must be engaged for onsite wastewater dispersal. We then install the system according to their specifications.
Most water tanks in rural residential areas require a fire-fighting connection.
