CWICR Estimate-vs-Actual Quantity Matcher

Quantities drift from what was bid the moment a project leaves the estimate and hits the field, but nobody notices which CWICR codes drifted the most — or why — until a pay app or a closeout reconciliation surfaces a total that's already too big to untangle line by line.

The skill matches the original estimated quantity against the actual quantity installed or consumed to date, code by code, computes the variance %, and flags any code whose overrun crosses a threshold you set — a potential unbilled change order or an estimating error, the skill flags it without deciding which. If you tag which flagged codes trace back to an approved plan change and which are waste or a mistake, it reports those as separate totals instead of one blended overrun number that answers neither question.

It doesn't infer the cause of an overrun from the numbers alone — a 20% concrete overrun looks the same on paper whether it came from a change order or over-pour, so untagged flags stay in a clearly labeled "cause unknown" bucket rather than being guessed at. It also doesn't decide whether a flagged overrun should be billed as a change order; that's a commercial call for the PM or estimator.

This is a different problem from Bloqbase's own "Gestor de Consumo Real de Materiales de Obra," a Spanish-market skill built for raw material families like ceramic, concrete, or steel with no shared coding standard behind them — it compares against a theoretical waste rate, not a bid quantity. This skill needs a CWICR code shared by both the estimate and the actual data to match rows with certainty, which only exists in US-coded projects.

How to use it with judgment: start with one real, well-defined case, enter only data you can verify, and keep the reviewed version. The goal is not to fill in another document for its own sake, but to turn a project decision into a record that someone else can understand and review later.

Before making it part of your process, check three things: the inputs come from an identifiable source, the calculations or wording match the actual project, and it is clear who must approve the result. If one is missing, treat it as working material rather than final project documentation.

How to prepare the input: start with a real case and define which question the skill must answer, which period the data covers, and which fields cannot be missing. Mark estimates or incomplete sources before requesting the analysis.

How to review the output: check that conclusions can be traced back to your data, inspect the rows or documents behind each alert, and discuss priority cases with the person responsible for the project. A skill helps organize judgment; it does not replace technical, contractual, or financial approval.

How to make it part of the workflow: keep the prompt, the source data, and the reviewed result with the project. This lets you repeat the analysis when progress changes, compare periods, and explain why a recommendation was accepted, rejected, or sent for review.

How to put it to work on a real project

The idea isn't to download another file and forget it in a folder. Use it with a specific case: a pending certificate, a coordination meeting, a cost overrun or a handover to the developer. Fill in the resource with real data from your project, validate the result with your own technical judgment, and keep it as an internal reference to repeat the process next time.
