Quanta runs your valuations, variations and final accounts — and turns every closed job into benchmark data your next one can trust.
Outturn cost is heavy-tailed: most jobs settle a few percent over contract sum, a handful settle thirty percent over — and the mean tells you almost nothing about which yours will be. Quanta measures drift on real closed projects and prices the tail, not the average.
Everything a post-contract QS runs month to month — built as one system of record, so the data you keep is the data you get paid to keep.
Interim valuations that finalise like contracts — locked, stamped and auditable, with a reopen trail when life happens.
Variations with cause codes, so the final account decomposes — client change, design development, unforeseen — instead of just totalling.
A live cost and forecast report the whole team reads from the same sheet — no more month-end spreadsheet archaeology.
Drawdown advice priced from the drift distribution of real closed jobs. It shows its sample size — and refuses to guess below it.
Every closed project becomes a frozen, human-reviewed benchmark record. The longer you run Quanta, the sharper your numbers get.
Cost plans and tender returns in CSV, Excel or PDF — extracted, arithmetic-checked line by line, and reviewed before a penny is trusted.
Cost plans, tender returns, breakdowns and final account packs arrive in different formats, layouts and naming conventions. Quanta reads the shape of the file, identifies the commercial structure, and turns it into reviewable cost data.
Accepts CSV, Excel and PDF paths without asking users to pre-template the document.
Detects headings, sections, quantities, rates and totals before mapping them into the cost model.
Flags uncertainty and arithmetic breaks for human review instead of pretending every import is clean.
84% of document value can be trusted before review; remaining value is isolated, explained and queued.
Benchmarking tools sell you someone else's averages. Quanta builds the dataset out of your own delivery — verified at the source, reviewed by a human, and frozen so a figure quoted today still means the same thing next year.
Close-out takes a snapshot a reviewer signs off. Benchmark queries read the frozen record — never a forecast that moves under you.
Sample size is printed next to every statistic. Below three comparables, Quanta refuses to answer rather than dress up a guess.
Cause-coded variations split the gap between contract sum and final account into client change, design development and genuine surprise.
"S&F PPC alu windows" maps itself the second time you upload. Corrections compound into a dictionary that's yours alone.
Cost documents are self-checking: quantity times rate equals total, lines sum to sections, sections sum to the document. Quanta uses that redundancy to verify every extracted line — so AI never gets the last word on your numbers.
A 400-line document isn't 400 decisions. Lines that pass every check arrive pre-accepted; your queue is the flagged minority, sorted by pounds at stake — with a running meter of how much document value is already verified.
Quanta is in private prototype, built with a chartered quantity surveyor at the table. If post-contract cost control is your day job, we'd like your red pen on it.
