Services

HVAC drafting services for Australian projects.

D&Z Drafting helps contractors, builders and consultants prepare clear mechanical drawings for review, coordination, construction and handover.

What we do

Practical drafting support when the drawings need to be clear and buildable.

Most jobs do not need fancy wording. They need drawings that are easy to read, easy to mark up and clear enough for the next person on the project to understand. We can help with HVAC shop drawings, ductwork layouts, Revit support, revisions and as-built updates for Australian construction teams.

01

HVAC shop drawings

Shop drawings for contractors who need the mechanical services set out clearly before work moves too far on site.

Read our guide to HVAC shop drawings for contractors.

Learn more about our ductwork layout drafting for construction projects.

We can document

  • Duct routes, offsets and riser connections
  • Diffusers, grilles, dampers and access panels
  • Mechanical equipment locations and connection points
  • Penetrations, supports and ceiling coordination areas

Typical outputs

  • CAD sheets for review or construction issue
  • Layouts developed from consultant drawings or markups
  • Drawing updates after coordination comments
  • PDF and DWG files ready to send to the project team
02

Mechanical drafting

Extra drafting support when your team needs clean mechanical services drawings, but does not want to slow the job down waiting for internal capacity.

We can support

  • Commercial fit-outs and tenancy upgrades
  • Apartment, education and public building projects
  • Plantroom layouts and mechanical services zones
  • Drawing clean-up from sketches, redlines or older CAD files

Good for

  • Tender, review and construction documentation
  • Coordination meetings and design review comments
  • Quick drawing changes during active projects
  • Contractors who need short-term drafting backup
03

Revit modelling and BIM support

Revit support for HVAC layouts where the model needs to match the drawing intent and stay useful for coordination.

We can model

  • Main duct runs, branches and fittings
  • Mechanical equipment and access clearances
  • Typical floors, repeated zones and plant areas
  • Model updates from coordination comments or markups

Deliverables

  • Revit model updates for mechanical services
  • Plan views and drawing sheets
  • Layouts prepared for coordination review
  • PDF exports for issue, discussion or markup
04

As-built drawings and revisions

Drawing updates for projects where site changes, installer markups or final handover requirements need to be cleaned up properly.

We can update

  • Site markups and redline comments
  • Equipment, diffuser and ductwork location changes
  • Drawing notes, legends and title block revisions
  • Final issue sets for handover records

Useful when

  • The installed work differs from the original drawings
  • Several markups need to be combined into one clean set
  • Handover drawings are needed without dragging the job out
  • Old CAD files need tidying before final issue

Start a project

Send through the drawings, markups or scope notes and we will let you know what is needed next.
