Pool Project Change Orders
Control scope, price, schedule, drawings, selections, and responsibility when the project changes after agreement.
Pool Builders Pro editorial · Updated September 23, 2026 · AI-assisted, source-reviewed consumer educationRecognize change triggers
Owner requests, site discoveries, authority comments, unavailable products, design coordination, quantity differences, and corrective work can affect scope. Not every field discussion is an authorized change.
Require a complete change description
Identify the reason, added and removed work, product or drawing revision, price basis, tax, schedule effect, milestone effect, and responsibility for connected work.
Review before changed work proceeds
The agreement and local rules determine process and exceptions. Preserve written authorization and avoid relying on memory after work is concealed.
Update connected documents
Revise scope matrices, selections, drawings, schedule, contract value, payment schedule, and allowance reconciliation so the current project record agrees.
Separate correction from owner upgrade
Ask whether a condition is included work, corrective work, unforeseen work, or an elective change. The classification affects responsibility and should be documented.
