How we measure steel
See a Structural Takeoff in 3D
Columns, beams and bracing are counted from the general arrangement, measured between grid lines and weighed by section — then connections, bolts and base plates are added, so the tonnage is ready to price.
- The general arrangement sets out the column grid — four lines by three at 6.00 m bays — and the floor levels the frame is built to.
- Every column is counted on the grid and measured to its full height, then weighed by section from the steel tables.
- Primary beams on each grid line are measured between column centres at both levels and weighed by section.
- Tie beams on the column lines and secondary beams across each bay are measured, counted and weighed in turn.
- Bracing bays are read from the elevations, with every diagonal measured corner to corner, storey by storey.
- Connections, bolts and base plates are counted joint by joint and an allowance added, so the tonnage is ready to price.

FAQ
Common Questions
Yes. Each member is measured by section size and length from the structural drawings and member schedules, then converted to tonnes using the section’s mass per metre. Plates, cleats and bolts are measured from connection details where shown, or added as a stated percentage allowance where they are not.
Yes. Wall, floor and roof framing quantities can be prepared from framing plans and details.
No. Our work is estimating and quantities; shop drawings are outside our scope.
