Scope and inputs to reconcile
Compare the specific sizing, vent, fixture and testing requirements that affect the project, using the designer’s selected sizes and arrangements.
Workflow and checks
Confirm the authority and permit edition, identify affected drawing details and measure any resulting quantity changes. Price those changes using the same supplier/labor basis for both options.
What the output should show
A comparison records the cited requirement, design difference, quantity delta and pricing assumption.
Exclusions and unresolved decisions
An estimator does not decide code adoption or approve an alternate design. Do not assume one model code always requires larger pipe.
Documents to share for a quote
Provide permit/jurisdiction information, designer notes and approved baseline/alternate documents.
