Commercial hydraulic & civil plumbing · Melbourne
We read your drawings, raise the questions in writing, and give you a scope with the exclusions stated. Family run, VBA licensed, working across Melbourne’s south-east.
What we do
Carrying both scopes removes the interface argument that costs builders time when two subcontractors meet at the boundary.
HYD — HYDRAULIC SERVICES
CVL — CIVIL DRAINAGE
Retail · Government · Industrial · Commercial multi-residential
How we work
They come from pricing an incomplete set of drawings. We front-load that risk instead.

About Normac
David MacHugh established Normac in April 2022, after nearly two decades on the tools and eight years in project management and estimating. That estimating background is why our proposals read the way they do — written to be compared, not argued about later.
Normac is family-run: David on the tools and in the estimating, Freya running the office. We work to capacity rather than to opportunity — if we can’t resource a package properly, we’ll tell you at tender rather than at week three.

The more of the document set we have, the firmer the proposal. Attach what you’ve got and we’ll tell you what else we need.
