How we measure HVAC
See a Mechanical Takeoff in 3D
Ductwork is measured along its centreline by size and converted to m² of sheet metal, then plant, air terminals, insulation and pipework are counted and measured — so the schedule is ready to price.
- The mechanical layout sets out the zones served, the plant position and the floor dimensions the ductwork is measured to.
- The air handling unit and condensing units are counted from the equipment schedule and located on the plant pad.
- Supply ductwork is measured along its centreline by size — main, reducers and branches — and converted to m² of sheet metal.
- Return ductwork back to the AHU and the WC extract run are measured the same way, and the exhaust fan is counted.
- Supply diffusers, return and exhaust grilles and VAV boxes are counted by type and size from the layout.
- Duct insulation is measured in m² and refrigerant pipework in lineal metres, so the schedule is ready to price.

Quantities measured and organised.
Review & delivery
Checked, then delivered in your format.
Ductwork is measured by size and type along its centreline, in lineal metres or converted to m² of sheet metal, whichever suits your pricing. Bends, transitions and fittings are counted or allowed for as you prefer, and the method is stated in the assumptions.
Yes. Where layouts are schematic, we state assumptions for routes, lengths and sizes so they can be reviewed before pricing.
Yes. Equipment is scheduled from the drawings and equipment schedules. Where you have supplier quotes for major plant, we can include them in the estimate as supplied.
