Bendline

REBAR · CONCRETE · BLOCKWORK

Site quantities, worked out to the last bar and the last bag.

Bendline calculates rebar bar-bending schedules, concrete mix quantities and blockwork takeoffs — across IS 456, ACI 318 and BS 8666 — so you can stop re-deriving the same numbers on-site.

BEAM B1 — SECTION A-ASCALE 1:10 · BS 8666REV 0323045025mm COVER

Three calculators, one bill of quantities.

Rebar & BBS

Beams, columns (rectangular or circular), slabs with openings, footings — bend deductions and hook allowances by code.

Concrete mix

Volume in, cement bags / sand / gravel out, using the standard dry-volume method contractors use on site.

Blockwork

Wall area minus openings, block count with wastage, mortar cement and sand — 6" or 9" block.
