Field Order

In Plain English

A written instruction from the architect directing a small change in the work that doesn't change the price or schedule.

Definition

A field order is a written directive issued by the owner or architect during construction that authorizes a minor change in the work that does not affect the contract sum or completion date. Field orders clarify design intent, resolve minor conflicts in the documents, or direct small adjustments to fit existing conditions. Changes that affect cost or schedule are handled through change orders rather than field orders.

Why It Matters in Bidding

Knowing the line between a field order and a change order protects a contractor's margin, because accepting work directed by a field order means agreeing it has no cost or schedule impact. Estimators and PMs must scrutinize directives carefully, since accumulated minor field orders can quietly erode budget if any actually warranted a priced change order and the right to compensation was waived.

Example

When the architect issues a field order shifting a non-structural partition six inches to clear an existing pipe, the PM confirms the move adds no material or labor cost before signing, keeping it out of the change-order log.

Frequently Asked Questions

A field order directs a minor change with no effect on contract price or schedule, while a change order formally adjusts the contract sum or completion date. The distinction matters because signing a field order can signify acceptance that no compensation is due, so contractors verify there is truly zero cost impact.
Yes, when the directed work actually carries added cost or time. The contractor should respond in writing that the change requires a change order rather than complying silently, because performing extra work under a field order can waive the right to be paid for it later.
Typically the architect or owner's representative issues field orders to clarify intent or direct small adjustments. Authority depends on the contract, so the project team confirms who holds it and documents each directive, since a verbal instruction outside the field-order process can create disputes over scope and payment.
