Change Order Number
Unique identifier for traceability across project records and invoices; reference the contract number and original change order sequence to avoid confusion.
A written concrete change order protects project stakeholders by documenting scope, cost, schedule impact, and approvals. It creates a definitive contract amendment and reduces the risk of payment disputes or claims.
The following roles commonly prepare, review, and sign concrete change orders on construction projects.
Ensure every role listed receives a copy of the executed change order and that the contract file is updated to reflect the amendment.
A senior on-site manager authorized by the contractor to request changes, describe field conditions, and initiate pricing or time-impact estimates for subcontractor approval and owner review.
An owner or owner's representative with delegated authority to approve contract amendments and sign change orders that alter the contract sum or completion date.
