Change orders and scope protection for contractors

Many profit problems start when a small extra request becomes unpaid work. Change-order language gives the contractor and client a clear process for handling changes.

Define the original scope

Before you can protect against added work, the original work must be clear. State what will be done, where it will be done, and what is included in the price.

Name the likely exclusions

Every trade has common surprises. Hidden damage, bad access, disposal changes, material substitutions, extra repairs, and customer-requested upgrades should be addressed before the job starts.

Use a written approval step

A simple sentence can protect the job: added work, hidden conditions, or material changes require written approval before the added work continues.

Update price and schedule together

A change order should explain the cost impact and the schedule impact. More scope often means more time, more materials, and different completion expectations.
