HYD · Hydraulic services

The in-building scope, coordinated with everyone else’s.

Water, gas, sewer and sanitary, pumps, tanks and wet fire services for commercial construction. Hydraulic is one of the first trades in and one of the last out, so the package is only as good as its coordination with structure, civil and mechanical.

Labelled and tagged water and gas manifold with individually metered isolation valves
Metered manifold, multi-residential — every unit individually metered, isolated, labelled and tagged. Any unit can be shut down without touching the others.

The problem

Hydraulic gets priced early and built last.

The package is tendered off drawings that will be revised, then installed after the structure is up, the civil is in and the mechanical has already taken the ceiling space. Every one of those changes lands on the hydraulic contractor, and the builder wears it as either a variation or a delay.

The way to reduce that is not to build faster at the end. It’s to read the whole document set at the start, walk the site, and get the conflicts on paper while they can still be resolved with a drawing revision instead of a demolition saw.

WHAT THIS MEANS FOR YOU

  • Clashes identified at documentation stage, not at rough-in
  • A priced scope with the exclusions written down, so tenders compare properly
  • RFIs issued to you and the consultant before the proposal, not after award
  • One contractor across hydraulic and civil, so no boundary argument mid-build

Scope detail

What sits inside a hydraulic package.

Which of these apply depends on the project. The proposal states exactly which are in and which are out.

WTR

Water services

Incoming supply, metering, reticulation, isolation and tempering. Includes individually metered manifolds where each tenancy or unit needs independent isolation.

GAS

Gas services

Supply, metering and reticulation to appliances and plant, coordinated with the equipment schedule and the appliance connection requirements.

SAN

Sewer and sanitary

Sanitary drainage, stacks, vents and fixture connections, set out against the architectural fixture layout and the civil connection points.

PMP

Pumps and pump sets

Pressure sets, sewer and sump pumps, duty and standby arrangements, level controls and alarms, commissioned and documented.

TNK

Water tanks and rainwater harvesting

Storage, break tanks and harvesting tanks with charged lines, first flush, pumps and reuse reticulation for irrigation, flushing or washdown.

TWT

Trade waste tanks and grease arrestors

Tanks, arrestors, sampling points and connections, with the authority requirements addressed at design stage rather than at inspection.

WFS

Wet fire services

Wet fire pipework and equipment installed and coordinated with the fire engineering requirements and the certifying authority.

Delivery

On site with the other trades, not around them.

Hydraulic works touch nearly every other trade. Most of the delay on a package comes from sequencing, not from the pipework.

01Program coordinationRough-in and fit-off sequenced against structure, civil, mechanical and electrical.
02Site team consultationWe work with your site team rather than around them — issues raised on site, not escalated later.
03Variations priced fastDrawing revisions turned around quickly, so a change doesn’t stall the front.

Questions we get asked

Before you send the drawings.

FAQ

  • What package sizes do you take? Our resourcing sweet spot is $30k–$150k, and we take packages up to around $200k. Above that we’d rather tell you at tender than over-commit.
  • How long does a proposal take? Around two weeks from a complete document set, longer on complex packages. We’ll tell you the date when we acknowledge the enquiry.
  • Will you price off incomplete drawings? We will, but the exclusions will be broader and we’ll say so plainly. A complete set gets you a firmer number.
  • Do you carry the civil scope too? Yes — hydraulic and civil drainage in one package, which removes the interface between two subcontractors.
  • What happens if drawings are revised after award? Variations are priced and issued quickly so the decision sits with you before it affects the program.

Next step

Send the hydraulic and architectural set.

We’ll read it against the civil, tell you what’s missing, and come back with a scoped proposal.
