Engineering Precision
ASTM A615 / A706 Standard Rebar Unit Weight Schedule
We never lump rebar into arbitrary allowances. Every linear foot is converted into exact pounds (LBS) and US Tons using standard ASTM unit weight coefficients:
| Bar Designation | Nominal Diameter | Unit Weight (LBS/FT) | Typical Construction Application |
|---|---|---|---|
| #3 | 0.375" | 0.376 lbs/ft | Ties, stirrups, light slabs, temperature mesh |
| #4 | 0.500" | 0.668 lbs/ft | Residential footings, 4"–5" slabs-on-grade, curbs |
| #5 | 0.625" | 1.043 lbs/ft | Commercial continuous footings, stem walls, grade beams |
| #6 | 0.750" | 1.502 lbs/ft | Heavy commercial foundations, retaining walls, columns |
| #7 | 0.875" | 2.044 lbs/ft | Industrial heavy equipment pads, bridge decks, shear walls |
| #8 | 1.000" | 2.670 lbs/ft | Deep drilled piers, mat foundations, crane pads |
| #9 | 1.128" | 3.400 lbs/ft | Multi-story building column cages, high-load transfer girders |
* Includes CRSI standard lap splice calculations (Class B tension laps) and 3D hook allowances.100% Bar Bending Schedule (BBS) Support
Preventing Jobsite Shortages
How are net and gross concrete cubic yards calculated?
One of the most dangerous mistakes an estimator can make is submitting net drawing quantities without factoring in field loss, pump line residue, and subgrade over-excavation. Running short on a 150-yard pour causes costly cold joints and emergency ready-mix short-load charges.
Continuous Footings & Trenches (8% – 12% Waste Factor)
Earthy trench walls slough off during backhoe excavation. An earth-formed trench almost always pours 10% wider than nominal plan dimensions.
Formed Slabs-on-Grade (4% – 6% Waste Factor)
Rigid plywood and edge forms contain lateral spillage. Waste accounts for sub-base undulation, vapor barrier wrinkles, and screed leveling tolerances.
Pump Truck Hopper & Line Residual (1.0 – 2.0 CY Fixed Allowance)
Concrete pump trucks leave 0.75 to 1.5 yards in the hopper and boom delivery pipes during washout. We separate this line item so you never absorb the expense.
Formula Reference Card
// Cubic Yardage Formula
Volume (CY) = (L × W × T) ÷ 27
* Length (ft) × Width (ft) × Thickness (ft)
// Formwork Contact Area (SFCA)
SFCA = Perimeter (LF) × Height / Depth (ft)
* Measured on all vertical contact faces
// Gross Bid Quantity
Gross CY = Net Calculated CY × (1 + Waste%)
* Highlighted separately in your deliverables

Questions about hiring a concrete takeoff
Can the waste allowance be changed?
The measured net quantity stays fixed. Any waste or pump allowance is a separate row identified in the quote.
