Quantity takeoff

Structural steel tonnage from AISC shapes and plates, concrete volume, reinforcing bar weight and formwork contact area, each with your waste or allowance factor. Use it for budget quantities, a check on a fabricator's or contractor's takeoff, or the quantities that go with a set of calculations.

Inputs of the quantity takeoff #

• Steel shapes: item, AISC shape name (W12X26, HSS6X6X3/8, C10X15.3, L4X4X1/2, any shape of the AISC Shapes Database v16.0), count and length. The weight per foot is the database's nominal weight.
• Plates: item, thickness, width, length and count, at the unit weight of steel (490 pcf).
• Steel waste and connections: your allowance for connection material, stiffeners, bolts and waste (5 % prefilled).
• Concrete: item, length, width, depth, count and the formed faces (none, sides, bottom, sides and bottom, all faces) for the formwork contact area. Concrete waste and formwork allowance are your factors.
• Reinforcing bars: item, bar size (#3 to #18), count and cut length (with hooks and laps, or allow for them with the bar laps and waste factor). Weights are the ASTM A615 / A615M Table 1 nominal weights, the same for A706.

There is no auto-design: nothing is sized here.

Checks performed #

The report prints a table per material with every row.

Limitations #

• Concrete elements are rectangular prisms: deduct openings or add haunches as rows of their own.
• Connections, bolts, welds, stiffeners, deck, studs and miscellaneous metals are only in the waste factor unless you enter them.
• No costs.

Verification examples #

Verification status: 6 values compared in 5 examples (5 published, 0 hand calculations from the cited equations): 6 within tolerance, 0 recorded deviations. Code basis: the provisions it uses were read in the target edition.
