THE REBAR WORKFLOW

From the Structural Plans to a Reinforcement Estimate in One Workflow

STEP 01

Upload the structural plans

Start with the foundation plan — the sheet whose outline and area drive the footing, wall, and slab reinforcement runs.

STEP 02

Foundation geometry

Vega resolves the foundation perimeter and slab area from the plan — the same geometry Structural Concrete and Flatwork use, so the trades never disagree on the outline.

STEP 03

Reinforcement rules

You enter the bar size, grade, coating, and layout — footing bars, wall spacing, pier bars, slab reinforcement type. These are your rules, not something Vega reads off the sheet.

STEP 04

Bar quantities

Vega derives rebar LF per element — footing bars × perimeter, wall horizontal + vertical grid, pier bars × height × count, slab mesh or grid — then adds lap and waste.

STEP 05

Material + labor

Rebar is priced per LF at the selected size × grade × coating, plus place-and-tie labor. Wire mesh is priced per SF. Accessories — tie wire, chairs — are a visible allowance.

STEP 06

Review & bid

Check the perimeter source, adjust the bar spec or spacing, toggle union labor, and carry the reinforcement estimate into a proposal alongside the concrete trades.

Vega derives bar LF from the foundation geometry and your reinforcement rules — the rules are yours to set and edit.

WHAT VEGA MEASURES FOR REBAR

Reinforcement Quantities Derived From the Foundation, Not a Bar-Count Guess

Rebar linear footage is derived from the concrete elements it reinforces — footing bars × the foundation perimeter, a wall grid by height and spacing, pier bars × height × count, and slab mesh or grid. Lap and waste are added on top, and tonnage is shown for transparency. The estimate prices per LF, not per ton.

Footing rebar
Continuous bars × footing run LF (from the foundation perimeter)
Default: 2 continuous #4 bars — editable
Priced per LF at the selected bar size × grade × coating
Wall rebar (horizontal + vertical grid)
Horizontal bars: ceil(wall height ÷ spacing) × perimeter LF
Vertical bars: ceil(perimeter ÷ spacing) × wall height
Wall height from foundation type: basement 8′, crawl 5′, stem 4′
Pier rebar
Vertical bars × pier height × pier count
Default: 4 bars per pier, 5′ height — both editable
Pier count entered from the survey — not read from the plan
Slab reinforcement
Wire mesh (light residential) — priced per SF of slab area
Rebar grid (both directions) — priced per LF at slab area ÷ spacing
None — selectable when the slab carries no reinforcement
Lap, waste & accessories
Lap: one splice per 20′ stick × 40× bar diameter (editable)
Waste: 8% over-order allowance on cut/lap footage (editable)
Tie wire, chairs & bolsters — a visible $/LF allowance, not buried
Labor & tonnage
Place & tie labor at $1.25/LF (union = +20%, editable)
Weight (lbs) and tons derived from bar weight per foot — transparency
Tonnage is shown for reference; the estimate prices per LF, not per ton

Material rates anchored to 2026 market data (#4 Grade 60 ≈ $0.65/ft). Excludes welded rebar to steel, mechanical splices, specialty dowels, masonry rebar, and post-tensioning — each separate scope.

REVIEWABILITY

See the Rules Behind the Number — and Change Them

A rebar estimate is only as good as the rules behind it. Vega shows where the footing and wall LF came from, lets you set the bar spec and layout, and flags the tonnage so you are never left with a black-box number.

See the perimeter source

The estimate shows whether footing and wall rebar LF came from the traced foundation outline, exterior walls, or the building footprint — so you know what is behind the number.

Set the bar spec

Switch bar size (#3–#6), grade (40 or 60), and coating (plain, epoxy, galvanized, stainless). The material rate recomputes with every change.

Adjust the reinforcement layout

Footing bar count, wall horizontal and vertical spacing, pier bars, pier height, and slab grid spacing are all editable — the whole chain recomputes.

Edit any price

Material $/LF, labor $/LF, mesh $/SF, and the accessory allowance are click-to-edit. Your overrides are saved and never replace the system defaults.

Tonnage, not a black box

Weight and tons are shown for reference — the estimate prices per LF, so you are never left guessing what a ton costs or whether the number is real.

Derived, not detected

Vega derives rebar LF from the foundation geometry and your reinforcement rules. It does not claim to read bar marks off the sheet — the rules are yours to set and edit.

GENERAL CONTRACTORS

Carry rebar alongside the concrete trades

Estimate rebar alongside structural concrete, flatwork, and waterproofing — one foundation perimeter, one project, one proposal — instead of rebuilding each scope.

FAQ

Frequently Asked Questions

What is rebar estimating software?

Rebar estimating software helps contractors turn structural plans into reinforcement quantities — bar LF, lap, waste, weight, and tonnage — and then into material and labor pricing and a reviewable estimate. Vega is built around that workflow for reinforcing contractors and concrete estimators.

How does Vega get rebar quantities from the plans?

Vega derives rebar linear footage from the concrete elements it reinforces. Footing and wall rebar LF come from the foundation perimeter — the same geometry the Structural Concrete trade uses. Slab reinforcement comes from the slab area. You enter the reinforcement rules: bar size, grade, coating, footing bar count, wall spacing, pier bars, and slab reinforcement type. Vega multiplies those rules by the plan geometry to produce bar LF, then adds lap and waste.

Does Vega read bar marks or a rebar schedule from the drawing?

No. Vega does not read bar marks, rebar schedules, or bending schedules from the plan. It derives rebar LF from the foundation geometry and the reinforcement rules you enter — bar size, spacing, and counts. This keeps the estimate transparent and editable: you see exactly which rules drove the number, and you can change any of them.

What bar sizes and grades does Vega support?

Vega supports bar sizes #3, #4, #5, and #6, and grades 40 and 60. The material rate is priced per LF at the selected size × grade, with optional epoxy, galvanized, or stainless coating multipliers. Grade 40 is roughly 12% cheaper than Grade 60; epoxy and galvanized add about 40%; stainless is a premium upgrade.

Does Vega calculate lap splices and waste?

Yes. Vega adds one lap splice per 20-foot stick, with the lap length set to 40× the bar diameter by default — both the stick length and the lap factor are editable. An 8% waste allowance is added on top of the cut and lap footage, also editable. The ordered rebar LF you see already includes lap and waste.

Does Vega show rebar weight and tonnage?

Yes. Vega derives weight in pounds from the bar weight per foot for the selected size, and converts it to tons for reference. The estimate itself prices rebar per LF — not per ton — so tonnage is shown for transparency and for ordering, not as the pricing basis.

Does Vega estimate wire mesh and slab reinforcement?

Yes. For slabs, Vega supports three reinforcement types: wire mesh (light residential, priced per SF), a rebar grid (priced per LF, both directions, at an editable spacing), or none. You select the type in the breakdown and the whole slab scope recomputes.

Does Vega support post-tensioning or tendons?

No. Vega does not estimate post-tensioning, tendons, or prestressed cable. The rebar trade covers conventional reinforcing bar and wire mesh only. Post-tensioning is a separate specialty scope that Vega does not currently support.

How is rebar labor priced?

Place-and-tie labor is priced per LF of ordered rebar at $1.25 per foot by default, editable in the breakdown. A union labor toggle adds 20% to the labor rate. Slab mesh placement is priced per SF separately. Accessories — tie wire, chairs, and bolsters — are a small visible allowance per LF.

How does rebar relate to the Structural Concrete trade?

Rebar and Structural Concrete share the same foundation perimeter — the footing and wall outline that drives concrete LF also drives rebar LF — so the two trades never disagree on the building footprint. Structural Concrete deliberately excludes rebar and defers to this trade, and vice versa: the rebar estimate does not include concrete, forming, or placing. You can carry both in one project estimate.

Can I edit the rebar estimate after Vega creates it?

Yes. Bar size, grade, coating, footing and wall LF, footing bar count, wall spacing, wall height, pier count, pier bars, pier height, slab reinforcement type, grid spacing, lap factor, waste factor, and every unit price are editable. Union or non-union labor is a toggle. Edits are saved as your overrides and the whole estimate recomputes forward; clearing overrides restores the defaults.

What does the rebar estimate exclude?

The rebar estimate excludes welded rebar to structural steel, threaded and mechanical splices, specialty dowels (smooth, diamond, sleeves, baskets), and masonry rebar — each is separate scope. Shop-fabricated cages and epoxy or stainless upgrades are only priced when you select them. Concrete, forming, placing, and finishing are in the Structural Concrete trade, not here.
