The Situation

A $10B program, and one $5M line.

Capex at Vantage’s scale runs through thousands of pages of contracts, pay apps and invoices. A simple budget question meant asking a quantity surveyor, waiting for a spreadsheet, and hoping nothing had been snuck into the spend.

How Kos Works It

Ask Kos anything about any campus.

  1. Ask by email, like you would a colleague.

    “What have we paid Calder Power so far?” Kos answers in the thread with the PO, the milestones and what’s drafted.

  2. Kos checks the number against the budget.

    Where are we on electrical? Kos breaks it down by cost code and flags what’s billed ahead of the work.

  3. Pencil drafts reviewed against the contract.

    Kos reads every page of the GC’s pencil draft and holds stored materials without backup and change orders billed before they’re executed.

  4. Or ask in Slack.

    Kos answers in the channel the team already uses, with the field report behind it.

“How do we find the 5 million dollar item that just gets snuck into a 10 billion dollar capex spend?”
