The clarity to run the job

The job lives in ten places at once. We put it in one.

The estimate, the schedule, the code book, the contract, the group text. Builder's Knowledge Garden gathers them into one adaptive place that remembers every decision — and grows into the system of record for everyone on the build.

ONE PLACE

An adaptive command center

Budget, schedule, sequencing, codes, and contracts in one place that reshapes itself around the job in front of you.

MONEY

Budget and margin, live

Estimates, change orders, and draw requests stay tied to the work — so you always know where the margin is.

TIME

Schedule and sequencing

What happens next, in what order, and who is on it. Move one thing and everything downstream updates.

COMPLIANCE

The codes that apply here

California-first code coverage, jurisdiction-aware and cited to the source — not a search box, an answer.

PAPER

Contracts and change orders

Drafted, tracked, and attached to the work they govern. Nothing lives in a separate inbox.

MEMORY

A knowledge engine underneath

2,256 cited entities across codes, materials, methods, and safety — the memory beneath every answer.

One job, seven stages

From sizing it up to closing it out.

The same seven stages every job moves through — and the platform moves with it. No phase lives in a separate tool.

01

Size up

Is this job worth it? Scope, a ballpark cost, and the risk — before you commit.

02

Lock it in

Turn a yes into a signed scope, a real budget, and a contract.

03

Plan it out

Schedule, sequencing, permits, and the codes that apply — put in order.

04

Build

Run the day. Field reports, change orders, and crews — hands-free if you want.

05

Adapt

When one thing moves, the budget and schedule move with it.

06

Collect

Draws, invoices, and the money side — tracked against the work.

07

Reflect

Close out, capture what you learned, and carry it into the next job.

Built for everyone on the job

Nine lanes. One source of truth.

The general contractor carries the plan; everyone they bring on works free. Each lane sees the same project through the view that fits how they work.

GC

Carries the plan

Runs the job — command center, margin, pipeline, risk

Owner

Sees the build clearly — progress, decisions, and spend

Sub

Scope, schedule, and change orders in one thread

Supplier

Quotes, submittals, and deliveries tied to the work

Worker

What to do today — plain language, by voice, any language

DIY builder

A first project, guided from idea to permit

Equipment provider

Availability, logistics, and utilization

Service provider

Architect, engineer, inspector, lender, lawyer, future buyer

Robot / AI

Agents and drones query the same knowledge over MCP

Ask the garden

A plain-language answer, cited to the code.

Ask anything about codes, materials, methods, or safety. Every answer is jurisdiction-aware and cited to its source, drawn from 2,256 entities across 44 jurisdictions.

By voice or text, in 30+ languages — for the veteran GC and the first-day laborer alike.

CopilotExample
Do I need a vapor barrier under a slab in California?
Yes. Under California Residential Code R506.2.3, a Class I vapor retarder — typically 6-mil polyethylene — goes between the base course or prepared subgrade and the concrete slab, with limited exceptions.
