Scope and inputs to reconcile
Separate isolation, check, balancing, drain and control valves. Identify actuators, access panels and accessories only where specified.
Workflow and checks
Match each symbol or tag to its schedule, then reconcile valves shown in equipment assemblies against field piping counts.
What the output should show
Produce a valve register by tag/function with system, size, quantity, specification reference and vendor-package boundary.
Exclusions and unresolved decisions
Valve selection, control settings and access requirements should not be invented by the estimator. Actuator wiring may belong to another trade.
Documents to share for a quote
Provide valve schedules, legends, station details and the equipment supplier scope.
