AI for construction, built on your own documents
The methods are ancestral. The business runs on Excel, WhatsApp, and paper, even when it is a hundred-million-dollar operation.
Construction runs on scattered spreadsheets, WhatsApp photos, and paper, with thin margins that leak late and compliance documents tracked by hand. I build a custom Claude operations brain on your own job documents: ask anything across contracts and certifications in plain language, track costs against the index, and keep personnel compliance current. The construction group I built it for now resells it to other builders.
The reality on the jobsite
The methods are, in the builders' own word, ancestral. The business runs on Excel, WhatsApp, and paper, even when it is a hundred-million-dollar operation. Orders given over WhatsApp get lost and turn into blame the following week. Field data and payroll show up as a photo, a scanned paper, a thread of messages, with nothing behind them. It works, until it does not.
Inflation makes every number move
Costs swing so hard that three quotes for the same work are not even comparable, and budgets have to be re-indexed against the construction cost index. A project that finishes within a point or two of budget elsewhere can land anywhere here. Real margins are thin and leak late: a job projected in the mid-teens can come in at a fraction of that once every legal and informal cost is counted, and the deviations get consolidated by hand on a month's lag. By the time you see the leak, it has already happened.
Compliance can stop the work
Payroll for the informal workforce eats days every fortnight, and a labor or safety inspection can halt the jobsite if a document is not current. Site accidents become court cases, so the paper trail is not bureaucracy, it is protection. Most of it is tracked by hand, folder by folder, with the expiry dates living in someone's memory.
Why the usual fixes do not hold
More Excel and more WhatsApp give you no accountability and lose the documents. Generic construction software is built for someone else's rules, not yours, and now that custom is cheap, the made-to-measure suit beats the off-the-rack one. Generic AI on its own returns confident garbage, because it does not know your obra. Growth used to hide all of it, and margin compression just exposed it.
What I build
A custom operations brain that runs on your own job documents. Ask anything across your contracts and certifications in plain language and get the answer in seconds. Track costs against the index and see a deviation while you can still act on it. Keep personnel compliance current with alerts before a document expires, and capture a daily report from a two-minute photo, because a tool the field will not use is worthless. Every number that touches money is computed by code, and I define your business rules first, because most firms do not have them written down.
Proof
I built this for Concreto, an Argentine construction group with hundreds of workers across multiple jobsites. Their system, Capataz, reads their job documents, answers questions across them, and runs the cost and compliance control they used to do by hand. The strongest signal is what happened next: they started reselling it to other builders. Read the Concreto case study.
What you own
Everything I build is yours: the brain, the Skills, the account, built on your own documents and your own rules. We start with one jobsite or one process, prove it on your own data, and grow from there. Then every month the system does more than the month before.
Where this fits
Frequently Asked Questions
No. The brain sits on top of what you already use, built on your own documents and your own rules. You own all of it.
That is the test it is designed to pass. Field capture is a two-minute photo, not a form, because a tool the jobsite will not use does not count.
It tracks your costs against the construction cost index and flags a deviation early, with the math done by code and reviewed by you.
Then the page for developers who report to investors fits you better. (Link: /industries/real-estate-development.)
