Calculation basis :
This is not a substitute for BS 8666 / ACI 318 / CRSI tables. A responsible engineer must verify hooks, radii, laps and machine dimensions before fabrication.

1D MULTI-STOCK NEST
Cutting nest
Best-fit decreasing across multiple stock lengths, reusing kept remnants first. Heuristic — not a certified shop optimiser. Compared against a naive one-bar-per-piece baseline.

BID DESK
Diameter rate book
Steel + fabrication labour × bend-complexity factor + couplers + structural steel value. Complexity is a commercial knob, not a code rule.
