Koester Expectation for Change Orders
Title: Change Order Development
Department: Project Management / Operations
Applies To: PMs, PEs, Superintendents, Accounting, Ops Leadership, Subcontractors (when directed)
Objective
Provide a clear, repeatable, and auditable process to develop, price, negotiate, approve, and close Change Orders (COs) with complete documentation, accurate cost/schedule impacts, and strong client/subcontractor relationships.
Background
Applies to all projects and all scope, cost, or schedule modifications, regardless of origin or financial impact. This includes changes initiated by the Owner, Design Team, AHJ, unforeseen conditions, or as directed by the Project Manager.
This process applies to all change orders, including:
-
External Change Orders – Changes to the Prime Contract submitted to the Owner for approval and potential cost/schedule adjustment.
-
Subcontract / Commitment Change Orders – Changes issued to or received from trade partners.
-
Internal Change Orders – Budget-neutral or GC-responsible changes (e.g., scope gaps, coordination issues, or field-driven adjustments not passed to the Owner).
-
Backcharges – Cost recovery issued to trade partners for rework, deficiencies, or scope responsibility.
Things to Consider
-
Contract Documents: Prime Agreement, General and Supplementary Conditions, and all Exhibits (including markup rules, tax, and retainage).
-
All change orders shall be prepared in accordance with the Contract Documents, with specific attention to:
-
Division 01 requirements (procedures, pricing, documentation, and approvals)
-
Owner/client change order requirements and processes
-
Allowance and contingency provisions, as applicable
-
The Contract Documents shall govern all change order formatting, supporting documentation, and approval workflows.
-
Design Revisions: RFIs, ASIs, CCDs, Bulletins, Addenda, Sketches.
-
Field Documents: FWOs/T&M Tickets, Daily Logs, Photos/Measurements.
-
Systems: Procore (Change Events/Prime COs/Subcontract COs, Budget, Schedule), Company CO Tracker, Scheduling software (e.g., P6/MSP).
-
Templates: RFP to Sub(s), CO Description Template, NTE Authorization, Email subject format, Cost backup checklist.

-
Change Order (CO): Formal contract modification to value and/or time.
-
FWO/T&M: Field Work Order / Time & Material ticket signed daily.
