Here’s how to get ACI-compliant bar bending schedules (BBS) that actually work on-site.

Why Rebar Detailing Fails (And Costs You)

  • Wrong bar marks: Fabricators can’t match delivery to pour sequence

  • Missing lap lengths: ACI 318 violations create weak joints

  • No coordination: Rebar clashes with embeds, PT cables, and MEP

Araco’s 5-Step Rebar Detailing Process

Step 1: Drawing Audit
Every sheet reviewed for rebar schedules, bent bar shapes, and special conditions.

Step 2: ACI 318 Compliance Check

  • Lap splice lengths per ACI 318-19 Table 25.5.2.1

  • Development lengths calculated per load conditions

  • Hook types validated (standard vs. seismic)

Step 3: Coordination Overlay
Rebar placed against:

  • PT strand layouts

  • Embed plates and anchor bolts

  • MEP sleeves and penetrations

Step 4: BBS Generation
Each bar marked with:

BAR MARK | SIZE | LENGTH | SHAPE | QTY | LOCATION | NOTES
R101 | #5 | 18'-3" | A615 | 42 | Grid A1 | Std 90°

Step 5: Fabrication-Ready PDF
Shop drawings stamped, material summaries included, pour-break sequencing.

Real Results

  • 30% reduction in fabrication waste

  • Zero RFIs for rebar placement

  • 2-day pours instead of 5-day delays

Scope gaps, missed addendums, and labor miscalculations turn winning bids into losing projects. Here are the 5 most common mistakes—and how our checklist approach eliminates them.

1. Ignoring Addendums & Revisions

The Problem: 68% of bid documents change after initial release. Missing these creates massive scope gaps.

Araco Solution: Our team reviews all addendums within 24 hours. Every estimate includes a change log tracking revisions from bid release to submission.

2. Incomplete Drawing Take-Offs

The Problem: Partial plan reviews miss critical details like rebar schedules or foundation notes.

Araco Solution: Systematic checklist covers all drawing sheets—architectural, structural, civil, and MEP coordination drawings.

3. Wrong Labor Rates for Region

The Problem: Using national averages instead of regional union rates inflates or undercuts bids.

Araco Solution: Location-specific labor databases updated monthly, plus CSI Division 03 expertise.

4. Scope Gap Identification Failure

The Problem: “Assumed” items not called out in specs lead to change orders or losses.

Araco Solution: Every estimate flags RFIs for unclear scopes before submission.

5. Last-Minute Quantity Changes

The Problem: Final-hour plan changes scramble estimators during crunch time.

Araco Solution: Dedicated revision team handles bid-time adjustments in under 4 hours.

Result: Our clients report 98% estimation accuracy, winning 27% more bids on average.
