Commercial plumbing estimates for retail & industry.
From national supermarket chains to complex industrial facilities, commercial hydraulic estimating demands corporate compliance knowledge, specialist system experience and the precision to price what others miss.
Commercial projects consistently carry specialist systems that generalist estimators miss. Every one identified and priced individually, not averaged.
Commercial hydraulics: wider range, higher stakes.
Commercial and retail hydraulic estimating covers an enormous range of project types, from a national supermarket with corporate hydraulic specifications to an oil refinery with HDPE pipework, 11-metre ceilings, cooling pits, treatment tanks and specialist industrial drainage. Each project type demands different knowledge and a different approach.
The common thread is that commercial projects consistently have specialist systems that generalist estimators miss: grease management, trade waste connections, civil reinstatement works, industrial drainage and specialist pipe materials. A retail hydraulic estimate is not just the pipes, it is the asphalt, the concrete and the saw cutting around them.
SNZ prices what others overlook. From a standard retail estimate to a complex industrial scope requiring careful assessment of specialist systems, we confirm your timeline at the start of every engagement and deliver within it, with every commercial and retail system individually identified and priced from your actual drawings.
National retail hydraulic standards are non-negotiable. Woolworths Group specifications are detailed and exacting, and SNZ priced every item to the standard, on time.
Every commercial sector. Every project type.
The systems change with the building. So does the way we price them.

Breadth and depth.
From a national supermarket to an oil refinery, we have the range to handle every commercial project type and the depth to price the specialist systems.
Woolworths Belmont North
National retail · corporate hydraulic standards · Belmont North NSW

Oil Refinery Facility
Industrial process · 11-metre ceilings · the most technically demanding scope in our portfolio
The challenge
An oil refinery is the most technically demanding commercial scope we have priced. HDPE pipework, copper works, specialised fittings, cooling pits and treatment tanks, all within a facility with 11-metre high ceilings.
Specialist materials, extreme installation heights and complex process connections put this scope well beyond what a rate per square metre can capture.

- ▸Specialised fittings priced to the facility specification rather than a generic allowance
- ▸Grease arrestors, pressure vessels and RPZDs each scoped separately
- ▸Cooling pits and treatment tanks measured and priced in full
- ▸High-level installation access costed into the relevant lines
The outcome
- ✓Full hydraulic package correctly scoped for a complex oil refinery facility
- ✓HDPE pipework, copper works, specialised fittings, grease arrestors, pressure vessels and RPZDs all individually identified, specified and priced
- ✓The most technically demanding commercial scope in the SNZ portfolio
Belmont Citi Shopping Centre
Retail · trade waste & civil reinstatement · 10 tenancies
The challenge
The Belmont Citi Shopping Centre scope is a perfect example of the commercial estimating trap: trade waste and gas connections to 10 tenancies with full civil reinstatement works.
Most estimators price the hydraulic connections and forget the asphalt, the concrete and the saw cutting around them.
The SNZ approach
- ▸Complete scope priced across 10 retail tenancies
- ▸Trade waste and gas connections individually identified
- ▸Full civil reinstatement including asphalt, concrete and saw cutting
- ▸Scope gaps identified before tender
The outcome

We've been incredibly impressed with the responsiveness and professionalism of SNZ. Quick to respond, thorough in their work, and consistently reliable. Their attention to detail has made a real difference to our workflow. We see them as a valuable long-term partner.
Worth every penny. SNZ estimated a large commercial hydraulic, civil and fire package in SA on a tight timeline. Within 24 hours they had started on our quote. Their detailed estimate provided everything we needed to fill in the tender documents with ease.
Shoaib and the team went over and above to deliver in a tight timeframe. Everything was detailed and communication was 10/10. The breakdown was very thorough and transparent covering all aspects of the job. Will definitely be using SNZ on future projects.
