Common mistakes in construction quotes

Not including all costs

Forgetting tools, material transport or supervision creates losses. List all costs.

Not considering contingencies

Always add a percentage for contingencies (5% to 10%). Construction projects always have surprises.

Not specifying scope

If the scope isn’t clear, the client may ask for more than quoted. Specify exactly what’s included and what’s not.

Not requesting a deposit

Construction projects require capital to start. Always request a deposit.

Not documenting changes

If the client requests changes during construction, document the additional cost and get written approval before proceeding.

Best practices

1. Visit the site: Always visit the project before quoting to avoid surprises.
2. Request plans: Plans help you calculate exact quantities.
3. Quote separately: Labor and materials separately for greater transparency.
4. Include timeline: Execution time is as important as cost.
5. Document everything: Every agreement should be in writing.

Frequently asked questions

How do I charge for changes during construction?

Document the change, calculate the additional cost and get written approval from the client before proceeding.

What happens if the project extends?

If the extension is due to client causes, charge overtime. If due to contractor causes, assume the cost.

Do I include construction permits?

Permits are generally paid by the owner. Include it as a separate concept in the quote.

How do I handle warranties?

Specify warranty time for labor (6-12 months) and materials (manufacturer’s terms).
