For general contractors: a first draft of the takeoff, a bid your team approves, a schedule that updates itself, daily logs from voice notes and change orders priced before work moves.
The AI OS is a set of AI agents connected to your email, phone, documents and schedule. They draft the paperwork on a job so your estimator and project manager can check it instead of starting from a blank page.
Who it is for
General contractors and small builders who bid from plans, manage subcontractors and answer to clients on budget and dates.
The problem
Quantities get counted by hand, schedules are out of date by lunch, site notes live in a truck, and verbal changes never get priced.
What you get
A first draft of quantities from a plan set
Bids built from those quantities and your sub quotes
A schedule that updates linked tasks when one slips
Daily logs from voice notes
Change orders priced before work moves

Send a plan set, or watch the job run.
A plan set arrives and the AI runs a quantity takeoff for estimator review.
Sub quotes and quantities roll into a bid document for approval.
The accepted bid becomes a Gantt schedule with linked tasks.
A superintendent's voice note becomes a structured daily log.
A weather delay ripples through the schedule and subs are notified.
A change order is priced, approved and added to the budget and schedule.
What the demo shows
Every step, explained
Each button above plays one of these stories at Ironclad Builders (sample). Press one, or just read them here. All names and prices are made up for the demo.
Send a lead
A developer emails a set of plans. It ends with a proposal sent and a schedule built.
Whitfield Dev. emails plans for a job and asks for a bid by Friday. The sender is told a draft is coming today.
Who does it
The Front office agent receives and answers it.
Why it matters
The bid invite gets noticed and acknowledged straight away, not buried in an inbox.
The plan sheets are read room by room and quantities are counted: slab, framing, drywall and roof deck. Two sheets are flagged for a person to check.
Who does it
The Estimator agent drafts it. Your estimator reviews it.
Why it matters
You skip the highlighter stage, and a person still checks the sheets the AI was unsure about.
Sub quotes and the quantities roll into a priced bid.
Who does it
The Estimator agent builds it line by line.
Why it matters
Every trade is in one place, so a missing line is easier to catch before you commit to a price.
You approve the proposal. It is sent with a check-in set for Wednesday.
Who does it
You approve. The Follow-up agent sends it and chases it.
Why it matters
Nothing goes out without you, and a bid does not go quiet after sending.
The accepted bid becomes a schedule of linked phases, and sub calendars are requested.
Who does it
The Project manager agent builds it.
Why it matters
The numbers you sold and the dates you run come from the same source.
Simulate a call
A superintendent talks for 21 seconds, and rain does the rest.
Rob leaves a voice note from site about the day.
Who does it
The superintendent talks. The Project manager agent turns it into a written daily log.
Why it matters
The record gets made even on a tired Thursday. Good logs matter later if dates or costs are questioned.
The log is filed and shared with the client portal.
Who does it
The Project manager agent files it.
Why it matters
Clients see progress without calling you.
A weather delay moves framing back two days, and every linked task moves too.
Who does it
The Sub coordinator agent checks what depends on framing.
Why it matters
You see the knock-on effect in seconds, while the paper schedule on the wall is already wrong.
Affected subs get their new dates.
Who does it
The Sub coordinator agent sends them and logs replies.
Why it matters
Subs are not left turning up on the wrong day, and you avoid five phone calls.
Raise a change order
The client wants a covered patio. Nothing changes until it is priced and signed.
The client asks by text to add a covered patio. They are told it will be priced first.
Who does it
The AI OS replies. Nobody on site agrees to anything yet.
Why it matters
A verbal request gets written down instead of becoming free work.
Each line of the change is priced.
Who does it
The Estimator agent adds the lines. Your project manager checks them.
Why it matters
The cost is known before the work starts, not argued about afterwards.
The client signs, and you approve the amount and the extra days.
Who does it
The client signs. You approve it.
Why it matters
There is a signed record of what changed and why.
The contract value, draw schedule and finish dates all update.
Who does it
The Bookkeeper and Project manager agents update them.
Why it matters
Budget and schedule stay true to the job as it now stands.
Run the day
This plays the whole job in order: bid, schedule, daily log, delay and change order.

Day in the life
Before, and with the AI OS
6:30
Before
The superintendent's notes are in a truck, a text and someone's head.
Counting studs from a PDF with a highlighter.
Rain hits, and the schedule on the wall is instantly wrong.
Calling five subs one by one with new dates.
A verbal change order is never written down or priced.
With AI OS
Yesterday's voice note is already a filed daily log.
A takeoff draft is ready for your estimator to check.
A delay updates the schedule and flags every linked task.
Subs have their new dates, and replies are logged.
The change order is priced, signed and in the budget.
This day is an illustration of how the work changes. It is not a measured result from a real business.
