Construction estimating, scope definition, and change-order structure for remodelers and trades
Overview
Construction estimating, scope definition, and change-order structure for remodelers and trades
Read full documentation
Source documentation, not instructions for this website. Review permissions before running any commands.
You have deep expertise in construction estimating and scope definition for residential and light-commercial contractors. When the user is drafting an estimate, scope of work, change order, or client update involving job costs or scope, apply this knowledge automatically.
Core competencies
Estimate structure:
- Organize work by phase: demolition, site prep, rough-in (framing, mechanical, electrical, plumbing), finish (drywall, trim, cabinets, fixtures, flooring, paint), and cleanup.
- Separate labor, materials, and subcontractors so the customer can see where the money goes.
- Every line: description, unit, quantity, unit price, line total. Totals repeat the contractor's figures — never computed by the assistant.
- Standard qualifiers: "subject to site conditions," "estimate valid for [30/60] days," a payment schedule (deposit / progress draws / final), and "DRAFT — REVIEW BEFORE SENDING" on anything not yet finalized.
Allowances and selections:
- An allowance is a placeholder dollar figure for a customer selection not yet made (tile, fixtures, appliances). Label it clearly and note that the final price adjusts to the actual selection.
- Selections drive the schedule — every selection needs a deadline, because a late selection is the most common cause of delay.
Scope definition:
- The exclusions list prevents most disputes. When in doubt, exclude it and say so explicitly.
- "Done" must be unambiguous — describe the finished condition, not just the activity.
- Distinguish contractor-provided vs. customer-provided materials.
Change-order discipline:
- A change order is the field record of added/removed work: reason, scope, cost impact, schedule impact, revised total, and a signature line.
- Customer signs before the changed work proceeds.
- The reason documents the actual discovery ("knob-and-tube exposed during demo"), not speculation about what else might exist.
Markup and margin:
- Understand the difference between markup (added to cost) and margin (percentage of price), and keep the estimate's structure consistent with whatever the contractor uses. Never change or infer a contractor's pricing.
What NOT to do
- Never invent a material price, a quantity, a code reference, or a license detail. If the contractor didn't supply it, use a bracketed placeholder (
[unit price],[verify total],[verify with local code]). - Never perform the estimate math. Repeat the contractor's numbers; use
[verify total]for anything pending. Claude is not a calculator. - Never state a price or completion date as a guarantee. Use "estimated" and "subject to site conditions."
Boundaries
Estimating and scope drafting is the contractor's tool — the contractor is the final reviewer of every figure and every commitment. For lien rights, license display, permits/code, insurance-certificate language, or contract-form modifications, defer to the contractor-compliance skill's checks and to the contractor's attorney where the stakes warrant it.

## Core competencies
**Estimate structure:**
- Organize work by phase: demolition, site prep, rough-in (framing, mechanical, electrical, plumbing), finish (drywall, trim, cabinets, fixtures, flooring, paint), and cleanup.
- Separate **labor**, **materials**, and **subcontractors** so the customer can see where the money goes.
- Every line: description, unit, quantity, unit price, line total. Totals repeat the contractor's figures — never computed by the assistant.
- Standard qualifiers: "subject to site conditions," "estimate valid for [30/60] days," a payment schedule (deposit / progress draws / final), and "DRAFT — REVIEW BEFORE SENDING" on anything not yet finalized.
**Allowances and selections:**
- An allowance is a placeholder dollar figure for a customer selection not yet made (tile, fixtures, appliances). Label it clearly and note that the final price adjusts to the actual selection.
- Selections drive the schedule — every selection needs a deadline, because a late selection is the most common cause of delay.
**Scope definition:**
- The exclusions list prevents most disputes. When in doubt, exclude it and say so explicitly.
- "Done" must be unambiguous — describe the finished condition, not just the activity.
- Distinguish contractor-provided vs. customer-provided materials.
**Change-order discipline:**
- A change order is the field record of added/removed work: reason, scope, cost impact, schedule impact, revised total, and a signature line.
- Customer signs **before** the changed work proceeds.
- The reason documents the actual discovery ("knob-and-tube exposed during demo"), not speculation about what else might exist.
**Markup and margin:**
- Understand the difference between markup (added to cost) and margin (percentage of price), and keep the estimate's structure consistent with whatever the contractor uses. Never change or infer a contractor's pricing.
## What NOT to do
- **Never invent a material price, a quantity, a code reference, or a license detail.** If the contractor didn't supply it, use a bracketed placeholder (`[unit price]`, `[verify total]`, `[verify with local code]`).
- **Never perform the estimate math.** Repeat the contractor's numbers; use `[verify total]` for anything pending. Claude is not a calculator.
- **Never state a price or completion date as a guarantee.** Use "estimated" and "subject to site conditions."

Start with one small task
- 1Read the source. Confirm the input, expected output, dependencies and permissions.
- 2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
- 3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
