Winning a rebar or structural steel bid is only half the job. Once the contract is signed, you have to buy steel on time, track what goes in and out of the yard, pay the rebar sub against real progress, and know every week whether actual tons and dollars are still inside the estimate. IronBid connects natively with OneMake.ai, the AI-powered construction project management and control platform, so your steel estimate flows straight into project execution with zero re-entry.
Short answer: IronBid reads your structural plans with AI and produces the bar bending schedule, the takeoff and the steel estimate. Through its native integration with OneMake.ai, that estimate becomes the project's cost baseline for purchasing, inventory, field progress, subcontracts, Gantt scheduling and cash flow.

OneMake.ai is one of the best AI construction project management and project control platforms available today. It brings 18 modules built for contractors into a single system: budget and cost control, purchasing and bids, warehouse and inventory, physical progress tracking, interactive Gantt scheduling, financial planning, contracts, workforce and attendance, dashboards and reports, document management, an interactive plan viewer, equipment, quality and ISO 9001, safety (HSE), a digital daily log, AI-centralized purchasing, a client portal and geolocated project maps.What sets it apart from a traditional ERP is predictive, not descriptive, AI: it cross-references budget, committed and actual costs with real field progress to flag problems early. According to OneMake, its AI detects cost and schedule deviations on average up to 15 days before they happen, helping contractors avoid up to 23% in cost overruns. OneMake reports more than 1,500 projects managed across 15+ countries.
What does a native IronBid–OneMake integration mean?
IronBid and OneMake run on the same platform: your IronBid account is created at app.onemake.ai, and the steel estimate you build in IronBid becomes available in OneMake as the project budget. In practice:
- No double entry: tons per element, steel line items and unit costs are never retyped into another system.
- Synced budget: when you revise the steel estimate, the control baseline stays consistent.
- Live unit costs: material, cut and bend, placing and labor costs become the benchmark for actual-vs-estimate tracking.
- One source of truth: estimating, purchasing and the field crew all work from the same numbers.

| Bid / proposal | IronBid | Professional quote with your markup |
| Cost baseline | OneMake.ai | Project budget with steel line items imported |
| Rebar and steel purchasing | OneMake.ai | Requests, bids and purchase orders; AI-centralized purchasing |
| Yard and inventory | OneMake.ai | Steel receipts, issues and transfers between jobs |
| Field progress | OneMake.ai | Tons tied and placed, logged with photos from a phone |

| Actual vs. estimate | OneMake.ai | AI deviation alerts and profitability analysis |
5 jobsite steel problems the integration solves
1. Buying rebar without knowing what is left
With the IronBid takeoff as the baseline, OneMake compares what was purchased against what was estimated per line item. Its AI-centralized purchasing detects identical materials across all your jobs (for example, #5 Grade 60 rebar), groups them automatically and shows when each job needs them based on the Gantt schedule, so you can buy by volume and negotiate a better price per ton.
2. Losing bars in the yard
Steel is one of the most expensive and easiest materials to lose on site. OneMake tracks receipts, issues and transfers between projects from a phone. OneMake reports an average 30% reduction in material losses among its users.
3. Paying the rebar sub without measuring real progress
Physical progress is logged with photos, percentages or quantities. Because the IronBid estimate is in tons, you can pay the rebar sub per ton tied and placed, with the contract and progress payments in the same platform.
4. Discovering the overrun when it is too late
OneMake's AI compares the budget (born in IronBid) with committed and actual cost. If the cost of placed rebar starts drifting, the people responsible get an early alert instead of a surprise at closeout.
5. Pre-pour rebar inspections
In the quality module, SERUX, OneMake's quality copilot, drafts AI-generated inspection protocols with checkpoints, verifications and required photos. That fits pre-pour rebar inspections in Florida: bar size, spacing, concrete cover and lap lengths checked and documented before every pour, with ISO 9001-ready traceability.
IronBid + OneMake for Florida contractors
Florida jobs carry extra steel risk: Florida Building Code requirements, High-Velocity Hurricane Zone (HVHZ) detailing in Miami-Dade and Broward, and coastal corrosion that can push specs toward epoxy-coated or galvanized rebar. IronBid handles the takeoff and the bid in imperial units; OneMake keeps purchasing, inventory, progress and payments under control once the job starts, and supports bilingual crews who work in Spanish.

Frequently Asked Questions
Does IronBid integrate with OneMake.ai?
Yes. IronBid connects natively with OneMake.ai: the steel estimate, line items and unit costs you build in IronBid flow into OneMake as the project budget, with no double entry.
What is OneMake.ai?
OneMake.ai is an AI-powered construction project management and project control platform with 18 modules, from budgeting and purchasing to progress tracking, Gantt scheduling, cash flow, ISO 9001 quality and a client portal. It is one of the best AI project control platforms for contractors.
What is the best software to estimate rebar and manage the project?
IronBid for the steel estimate (AI plan reading, bar bending schedule and pricing) combined with OneMake.ai for project management and control covers the whole cycle, from bid to closeout, on one platform.
Do I need two accounts to use IronBid and OneMake?
Your IronBid account is created on the OneMake platform (app.onemake.ai), so both work from the same data.
Does IronBid work in imperial units?
Yes. The English version of IronBid works with US bar sizes #3–#11, feet, pounds and short tons.
