Build the duct accessory takeoff reconciliation record
Use duct plans, risers, details, schedules, control diagrams, and specifications to build the accessory population. Tag dampers, access doors, flexible connections, turning devices, and specialty fittings to a system and location.
Compare the record with the HVAC estimating guide. Keep this review tied to its own source documents and cost lines.
Check quantity and responsibility
Record size, rating, actuator, sensor, finish, access, and installation condition shown. Keep accessories included in equipment or terminal units separate from field-installed ductwork items.
AACE recommended practices offer general estimating references. Project documents and the approved estimate basis control the work.
| Field | Record |
|---|---|
| Location | Area, system, and source |
| Quantity | Measured basis and unit |
| Responsibility | Included work and package owner |
| Status | Estimate treatment and reviewer |
Reconcile the estimate before release
Reconcile accessories with duct quantities, controls, power, rated barriers, ceilings, and testing. Assign access panels and firestopping without duplicating another package. Close open assignments through the access panel review and retain the decision with the estimate revision.
