AI prompt: Concrete contractor sub-base change order email
A concrete crew has opened the driveway, patio, slab, or small parking-lot job and found a hidden condition that changes the scope. The owner-operator needs a factual change-order email that explains what was discovered, why it affects slab performance, what it costs to fix, and what approval is needed before work continues.
The prompt
You are a concrete and paving contractor writing a change-order email to [client name] for [project type] at [property address]. Original estimate: $[original amount]. Discovery: [unsuitable sub-base / buried debris / extra demolition depth / missing reinforcement / high moisture / other]. Location and quantity affected: [square footage, depth, tons, linear feet, or area]. Why it matters: [slab support, drainage, compaction, reinforcement, curing, warranty, or schedule impact]. Additional scope required: [excavate, haul away, add crushed stone, compact, add rebar/mesh, re-form, other]. Additional cost: $[change-order amount]. Timeline impact: [same day / add X days / revised pour date]. Photos or proof attached: [photo numbers, video, test result, none]. Write an email under 220 words that: (1) states the discovery in plain language in the first two sentences, (2) explains why pouring over it would risk the finished slab using only the facts provided, (3) lists the added scope and exact cost, (4) requests written approval before proceeding, (5) updates the schedule, and (6) keeps the tone factual, calm, and not defensive. Do not invent engineering findings, permit requirements, warranty terms, discounts, legal threats, or compliance claims I did not provide.
What you’ll get back
A customer-ready concrete change-order email that documents the discovered condition, explains the practical slab-performance risk, states added scope/cost, and asks for written approval before extra work proceeds.
Tips for this one
- Send photos with the change order. A client who can see bad fill, buried debris, or missing base depth understands the added scope faster.
- Separate discovered conditions from your original bid assumptions so the email does not sound like a pricing mistake.
- Ask for written approval before proceeding. Concrete change-order disputes usually start when the crew keeps working after a verbal yes.
- Keep warranty or performance language limited to the terms you actually use. This page explains scope, not legal advice.
