Scope and inputs to reconcile
Separate underground drainage, in-wall fixture connections, risers and overhead distribution. Identify carriers and test assemblies that precede finish installation.
Workflow and checks
Price measured work by system and phase, then add specified excavation, sleeves, support and testing costs. Reconcile finish-package inclusions so fixtures and trim are not counted twice.
What the output should show
A phase summary should show material, labor hours, equipment and allowances with a drawing reference for each quantity basis.
Exclusions and unresolved decisions
Final fixtures, finishes, demolition and site utilities belong only where the agreed rough-in boundary includes them.
Documents to share for a quote
