Contractor field guide · Free template
Removing scope still needs a complete change order.
Define what will not be performed, what is already completed or committed, how the credit is calculated, and what changes elsewhere.
The short answer
Remove the work. Reconcile the whole contract.
A deductive change order identifies deleted work, confirms what remains, records completed labor and committed materials, calculates the agreed credit, and revises price, payments, and schedule.
The credit may differ from a bid line because the useful question is often what cost is actually avoided under the contract’s method?
Credit workflow
Separate deleted work from costs already incurred.
- 01
Mark the exact deletion
Use quantities, locations, drawings, and exclusions; state what remains.
- 02
Record status
Separate unstarted work from design, procurement, fabrication, mobilization, and labor already performed.
- 03
Inventory commitments
List ordered, delivered, returnable, reusable, obsolete, or excess materials and their disposition.
- 04
Show the calculation
Apply contract rules for labor, material, subcontract, overhead, profit, cancellation, and tax line by line.
- 05
Reconcile the job
Document patching, protection, warranties, payments, and schedule effects.

Worked examples
Why the credit may differ from the original line.
One bay deleted
Installation is avoided, while completed drawings and special-order cancellation remain documented.
Rooms removed after prep
Finish coats are deleted after protection, patching, and primer; only remaining work is avoided.
Area reduced
Boards and labor are avoided while design, delivered framing, railing transitions, and coordination remain.
A deletion can add work
Check every interface.
Patch the boundary
Omitted work can leave walls, floors, trim, utilities, or structure unfinished.
Decide ownership
State who keeps paid or nonreturnable material.
Update dependencies
Deletion can affect inspections, trips, access, and sequencing.
Redraw responsibility
Clarify boundaries when others complete the deleted work.
Research basis
Written changes should capture decreases too.
California CSLB says covered home-improvement price or scope changes must be written and signed before changed work begins. Oregon CCB recommends a process for changes to work or materials.
Federal construction clauses illustrate deductive issues such as avoided cost, time, excess property, credit items, and overhead/profit treatment. Those formulas do not automatically govern residential work.
This guide does not establish a fee, restocking charge, overhead treatment, or credit formula.
Deductive change order questions
Should the credit equal the original line?
Not necessarily. Disclose the method, completed work, commitments, and avoided cost.
What happens to ordered materials?
Agree on return, restocking, reuse, ownership, storage, or disposal.
Can additions and deletions appear together?
Yes. Itemize each before showing the net change.
Does deleting work shorten the schedule?
Only if the agreed analysis supports it.
