Vorker compiles the standards research, drafts the fee quote and the assessment report with charts, and offers the next phase when the permit lands. You approve everything.

No. Every quote, report and invoice is prepared and then waits for you. You can read it, change any line, reject it, or approve it. Nothing leaves the office on its own.
No, and it never signs anything. The calculations, the assumptions and the professional judgment are yours. Vorker does the work around them: the standards lookup, the report formatting, the charts, the fee letters and the chasing.
It compiles the applicable parts with clause references so you can check every one, and it flags what it is unsure about rather than guessing. Treat it as a prepared briefing from a diligent assistant: it saves the lookup hours, you keep the responsibility.
That is exactly the size it is built for. Vorker is made for consultancies where the engineers also write the fee letters, format the reports and chase the invoices. There is nobody else to hand that to, which is the point.
You give it the results in whatever form you have them, and it builds the report around them: structure, charts, clause references and your standard disclaimers. Every figure in the draft traces back to what you provided, and you review it all before it goes anywhere.
No. You talk to it the way you would brief a colleague, and it works inside the tools you already have: your email, your calendar, your files. The reports and quotes arrive as ordinary PDFs on your letterhead.
