Scope and inputs to reconcile
Record hot-water mains and branches, return pipe, circulation equipment, valves and specified insulation. Match heating and mixing equipment to schedules.
Workflow and checks
Trace supply and return routes separately through plans/risers and reconcile equipment station details with distribution counts.
What the output should show
Create system-separated quantities plus an equipment/accessory register and insulation quantities by size and requirement.
Exclusions and unresolved decisions
Temperature control, return balancing and heater capacity are engineering selections. Do not infer those requirements from fixture count alone.
Documents to share for a quote
Provide supply/return drawings, water-heater schedules, station details and insulation specifications.
