# AI for construction estimators

Prepare a bid-input version and exclusion sheet for construction estimators: three administrative tasks, a synthetic worked example, and a complete reviewed brief.

## Quick answer

For construction estimators, start with a **bid-input version and exclusion sheet** for the estimating lead. Expose estimate-input gaps before staff make pricing and quantity judgments. Righthand can help prepare the administrative draft from inputs you authorize; staff review its evidence and decide the next action.

## Three desk tasks

### 1. Check input versions

Compare referenced drawings and accepted addenda.

### 2. Organize supplier exclusions

Preserve what quotes do not include.

### 3. Prepare alternate questions

Keep requested alternatives separate from the base bid.

## Who owns each handoff?

| Input | Proposed assistant deliverable | Responsible person |
| --- | --- | --- |
| approved bid checklist and supplier quotation register | bid-input version and exclusion sheet with record references | estimating lead |
| Missing or contradictory fields | Exception and source-linked question | Named source owner |
| Approved next step | Reviewable coordination draft | Staff authorize external action |

## Worked example: three records, three outcomes

The following inputs and outputs are synthetic, not customer results. Read them as a test packet for this desk.

| Illustrative source row | Useful worked output |
| --- | --- |
| Bid K-51: takeoff spreadsheet names drawing Rev B; supplied addendum points to Rev C. | Prepare an estimate-input discrepancy for the estimator before treating quantities as current. |
| Bid K-52: supplier quote excludes delivery while the comparison assumes an all-in figure. | List the exclusion explicitly and prepare a clarification question rather than invent a total. |
| Bid K-53: scope line says an alternate is requested, not part of the base bid. | Keep the alternate separate in the evidence packet until staff decides its treatment. |

**Correction check:** Verify the bid reference, drawing version, and supplier exclusions before organizing the comparison. The assistant should not calculate engineering quantities or make the final commercial estimate.

## Complete first-run brief

> Prepare a bid-input version and exclusion sheet from approved bid checklist and supplier quotation register. Cover October 12–16, 2026; use America/Los_Angeles for date cutoffs. Include these source fields: bid ID, drawing revision, addendum, scope line, quote version, exclusion, owner. Trigger: Monday at 9 AM. Output: a source-linked Markdown draft in my private review thread, grouped by next action and owner. Reviewer: the estimating lead. Flag missing fields or conflicting versions. Leave takeoffs, engineering quantities, commercial pricing, and bid submission with authorized staff. Do not send messages, change source records, or spend money. Result check: Verify source revisions and quote exclusions with the estimating lead.

Replace the illustrative dates and source locations before running this task. Use an approved extract when a native connection and its exact actions have not been verified; the extract remains a snapshot, not live synchronization.

## First-week check and failure boundaries

Pilot one live bid’s administrative input pack and inspect it before the estimator’s existing quote-review deadline. Delivery exclusions can invalidate a price comparison. Addenda may alter which source version staff should use. Leave takeoffs, engineering quantities, commercial pricing, and bid submission with authorized staff. When an input changes, rerun the affected comparison and retain its source reference; do not overwrite the authoritative operational record with a draft.
