Who we are

A subcontractor that thinks like a builder.

23 Constructions Pty Ltd delivers drywall and fitout packages for head contractors, project managers and end clients across Melbourne. We run our own crews, hold our own supply relationships, and price every job off a measured takeoff rather than a guess.

Because we come from a quantity surveying background, our tenders arrive with the scope written out in full — what's in, what's excluded, and what we've assumed. That's fewer variations later and a programme you can actually build to.

  • Measured, not estimatedEvery quote is built from a drawing takeoff with figured dimensions flagged against scaled ones.
  • Scope written in plain termsInclusions and exclusions listed up front so the package is understood before it starts.
  • Own labour, coordinated on siteDirectly managed crews with a single point of contact for programme and access.
  • Compliant systemsFire and acoustic rated build-ups installed to the manufacturer's tested system.

What we do

Three trades, done properly.

Packages can be taken individually or as a combined drywall scope — most clients prefer one contractor across all three so there's no gap between the partition, the ceiling and the door.

Partitions

Steel stud framed walls from office bulkheads to full-height fire and acoustic separations.

  • Standard, fire and acoustic rated systems
  • Slab-to-slab and ceiling-height setouts
  • Bulkheads, nibs, shafts and services walls
  • Plasterboard lining, set and prepared for paint

Ceilings

Suspended and fixed ceilings, drop-downs and shadowline detailing across whole floors.

  • Suspended grid and plasterboard ceilings
  • Furring channel and concealed systems
  • Bulkheads, drop-downs and shadowline
  • Access panels and services penetrations

Doors & Hardware

Door sets supplied, hung and finished — including frames, hardware and fire tagging.

  • Solid core, glazed and fire rated door sets
  • Steel and timber frames
  • Hardware supply and installation
  • Certification tagging where required

Estimating & Takeoffs

In-house quantity surveying — partition and ceiling takeoffs, wall schedules, floor area calculations and drawing revision comparisons, delivered as structured workbooks.

Package Management

Programme coordination, site setout, progress tracking by stage, and progress claims against measured completion rather than percentages pulled out of the air.

How we work

01020304

Takeoff

We measure the drawings properly — partitions by linear metre, ceilings by area, doors by set — and flag anything that needs confirming on site.

Quotation

A written scope with rates, inclusions and exclusions, so there's no argument later about what was allowed for.

Delivery

Crews mobilised to programme, setout marked, and progress tracked stage by stage against the approved scope.

Handover

Defects closed out, certification and tagging supplied where required, and the floor left ready for the following trades.
