What we do.

Core service
Hydraulic estimating

Full plumbing and drainage estimates produced from your actual drawings. Every pipe, fitting and system individually measured using PlanSwift. Small to medium projects within 72 hours. Large scopes — timeline confirmed upfront.

Variation assessments

Design change on site adding hydraulic scope? SNZ prices variations from the revised drawings against the original — fast, accurate and defensible. Any sector, any scale.

Learn more
Design change comparisons

Two drawing sets compared side by side — exactly what changed, exactly what it costs. Clear, priced breakdown for contract administration, variation claims or commercial negotiations.

Learn more
Civil stormwater estimates

OSD systems, detention tanks, gross pollutant traps, civil drainage networks and stormwater infrastructure. Civil engineering foundation — SNZ prices civil hydraulics correctly where others miss items. Standalone or combined with the full building hydraulic estimate.

Budget pricing

Drawings are preliminary and will change multiple times before finalised? Get a ballpark hydraulic figure within 48 hours — without paying for a full detailed estimate you will need to reprice every revision. Clearly flagged as indicative. Always with a recommendation to get a full estimate before signing contracts.

01
Hydraulics only — no distractions
SNZ estimates plumbing and drainage exclusively. Not electricals, not structure, not fitout. Every hour of work is focused on one trade. That specialisation is your competitive edge.
02
Measured from your actual drawings
Every estimate is produced using PlanSwift digital takeoff from your specific drawings. No benchmark rates. No template pricing. No averaging. Your project, your numbers.
03
Independent review on every estimate
Before any estimate leaves our office it is reviewed by a second estimator. On a hospital or a 25-storey tower this is non-negotiable. Most firms skip it. We never do.
