Scope and inputs to reconcile
State the systems, sizes, materials and equipment to include. Identify owner-furnished fixtures, packaged accessories and alternatives before the schedule is prepared.
Workflow and checks
Agree the drawing revision and measurement rules. Reconcile pipe runs with risers, fittings and fixture schedules; list missing dimensions and supplier package questions separately.
What the output should show
Request descriptions, quantities, units, system/size groups and drawing references, with waste and spare parts distinguished from measured scope. Confirm the supplier’s required worksheet format.
Exclusions and unresolved decisions
A bill of materials is not an availability guarantee or a construction design. Installation labor, purchasing, taxes and delivery costs require separate agreement.
Documents to share for a quote
Send the plumbing drawings, specification sections, fixture/equipment schedules and intended supplier-use format. Review the main material takeoff scope before requesting the quote.
