Industry Overview

Every Retail Fit-Out Starts With Good Hydraulic Planning

Every retail is different, but every successful fit-out depends on one thing — a hydraulic system that supports efficient operation from opening day.

Oliver & Sons Plumbing works alongside builders, shopfitters and equipment suppliers to deliver commercial plumbing in accordance with the approved hydraulic design and construction program.

Key Differences

Why Retail Plumbing Is Different

Amenities & Kitchenettes

Customer and staff amenities and kitchenettes coordinated with the fit-out layout.

Drainage Modifications

Existing drainage is often reconfigured to suit new retail layouts.

Base Building Coordination

Services are coordinated with the builder and building management.

Fit-Out Integration

Plumbing integrates with joinery, electrical and other trades throughout the fit-out.

The Build Sequence

Construction Sequencing

01

Planning & Coordination

Review hydraulic drawings, confirm the project scope and coordinate the plumbing works with the builder before construction begins.

02

Hydraulic Rough-In

Install underground drainage, water services and in-wall pipework before wall sheeting and internal finishes.

03

Fit-Off & Equipment Connections

Install fixtures, equipment connections and complete the final plumbing fit-off once finishes are complete.

04

Testing & Commissioning

Pressure test the system, complete commissioning and provide the required compliance documentation before handover.

Our Approach

Working With Builders & Shopfitters

Oliver & Sons Plumbing works alongside commercial builders, shopfitters and building management, coordinating plumbing installations with the wider construction program to support efficient project delivery.

From new retail fit-outs through to tenancy refurbishments and reconfigurations, we provide dependable plumbing installations that prioritise quality workmanship, clear communication and reliable project delivery.

The Outcome

Our Objective

Whether you're fitting out a new retail tenancy or refurbishing an existing space, our objective remains the same — delivering commercial plumbing that supports practical completion and provides the plumbing infrastructure required for day-to-day retail operations following project completion.

Amenities & Kitchenettes

Retail amenities and kitchenettes including sinks, dishwashers and accessible toilets.

Hydraulic Rough-In

Slab penetrations, suspended pipework and drainage for new retail fit-outs.

Final Fit-Off

Fixture installation, tapware and appliance connections with commissioning where required.

Hot Water Systems

Hot water units sized for amenities and kitchenette demand.

Backflow Prevention

Backflow devices installed and certified where required.

Drainage Modifications

Reconfiguration of existing drainage for new tenancy layouts.

From Plans to Handover

We work alongside builders, shopfitters and other trades to deliver commercial plumbing in line with the construction program. From planning through to project completion, our focus is on quality workmanship, clear communication and completing our plumbing scope efficiently.

Every plumbing stage needs to align with construction milestones to avoid delays, minimise clashes with other trades and achieve practical completion on schedule. Our process is designed around commercial builders, ensuring every stage is completed efficiently and communicated clearly.

04

Trade Coordination

Coordinate with cabinetmakers, electricians, tilers, kitchen suppliers and other trades throughout construction.

05

Fit-Off

Install fixtures, tapware and equipment connections once cabinetry, finishes and equipment are complete.

07

Handover

Final inspection, certification and project handover ready for practical completion and tenancy opening.

Working With Builders

Built for Commercial Builders

Commercial fit-outs rely on close coordination between multiple trades. Our role is to complete our plumbing scope in accordance with the approved hydraulic design while working alongside builders, shopfitters and other contractors throughout construction.

Direct Communication

We communicate directly with builders, site supervisors and project managers throughout the project, responding to RFIs, confirming plumbing requirements and coordinating our work with other trades.

Key point — A direct line to the site team, not layers of sub-contractors.

Common Requirements

Common Plumbing Requirements for Retail Fit-Outs

Fit-Out Services

Slab penetrations, suspended pipework and drainage for new retail fit-outs.

Set-downs, penetrations and service locations are confirmed during rough-in, ahead of wall sheeting and finishes.

Key Considerations

  • Drives the rough-in program.
  • Coordinated with the fit-out layout.

Customer and staff amenities and kitchenettes including sinks and accessible toilets, coordinated with the fit-out layout.

Set-downs are confirmed during rough-in, ahead of cabinetry and finishes.

Key Considerations

  • Coordinated with the fit-out layout.
  • Set-downs confirmed early.

Sinks, dishwashers and boiling/chilled unit connections coordinated with the kitchenette layout.

Water, waste and drainage set-downs are confirmed with the cabinetmaker during rough-in.

Key Considerations

  • Coordinated with the kitchenette layout.
  • Set-downs confirmed early.

Water Services

Hot and cold water rough-in and fit-off to fixtures, equipment and amenities across the fit-out.

Set-downs are confirmed during rough-in, ahead of cabinetry and finishes, so taps, basins and equipment connect correctly at fit-off.

Key Considerations

  • Roughed-in ahead of finishes.
  • Set-downs confirmed with relevant trades.

Hot water systems serve the continuous demand of the fit-out across basins, sinks, equipment and amenities. The system is sized to the fixture and equipment load to avoid undersupply during service.

Selected at design stage, roughed-in with the other hydraulic services, and connected and commissioned during fit-off where required.

Key Considerations

  • Sized to simultaneous demand.
  • Roughed-in and commissioned during fit-off where required.

Where required by the water authority, backflow prevention devices are installed, tested and certified by the appropriately licensed person where applicable.

The device is integrated into the hydraulic design during rough-in where required.

Key Considerations

  • Installed where required by the authority.
  • Tested and certified where applicable.

Drainage & Waste

Drainage points set into the floor to carry wash-down water and spillage to the drainage system, keeping the floor safe and operable during cleaning.

Positions and falls are set during rough-in, before the slab or screed is poured — falls cannot be adjusted once the floor is cast.

Key Considerations

  • Coordinated with the tiler and waterproofer.
  • Falls locked in before the floor is cast.

Reconfiguration of existing drainage to suit new retail layouts within an existing base building.

Drainage changes are confirmed during rough-in, coordinated with the builder and building services.

Key Considerations

  • Coordinated with the builder and building services.
  • Confirmed during rough-in.

Carries wastewater from fixtures, equipment and floor wastes to the sewer or trade waste system.

Pipe sizes, falls, junctions and discharge points are set before the slab is poured. Because falls cannot be adjusted once the floor is cast, the layout has to be right at rough-in.

Key Considerations

  • Drives the rough-in program.
  • Coordinated with the layout and equipment schedule.

Completion

Pressure testing and commissioning confirm the hydraulic system performs as specified. Water services are pressure-tested, drainage flows checked, and fixtures and equipment connections commissioned where required.

Testing and commissioning are scheduled during fit-off so any issues are resolved before final sign-off.

Key Considerations

  • Part of the fit-off sequence.
  • Confirms the system performs as specified.

Depending on the project and local authority requirements, fit-outs may require inspections relating to the plumbing installation. Where an inspection forms part of our plumbing scope, we prepare the relevant plumbing work for inspection at the appropriate stage of construction and complete any required plumbing rectifications before progressing.

Key Considerations

  • Inspection requirements vary between projects and local authorities.
  • We prepare plumbing work for inspection where it forms part of our scope.
  • Any required plumbing rectifications are completed before progressing.
