Build the firestopping penetration takeoff review record

Locate rated walls, floors, shafts, joints, and smoke barriers before counting penetrations. Build the population from architectural life-safety plans and coordinated trade drawings.

Record the barrier rating and location with each opening instead of counting devices in isolation. Use the mep scope interface matrix as a related control, but keep this takeoff tied to its own drawing population and cost lines.

Check quantities and scope conditions

Classify the penetrating item, material, size range, annular condition, sleeve condition, and grouped or single service. Do not select a product or tested system unless project documents and an authorized reviewer support that choice. Price uncertainty as a stated basis.

AACE recommended practices provide general estimating references. The project documents and approved estimate basis control the actual quantity and scope decisions.

Reconcile the estimate before release

Reconcile responsibility for sleeves, layout, access, backing, inspection, labels, and repair after other trades disturb completed work. Compare the final count by floor and trade to expose missing areas and duplicate coverage. Close open assignments through the construction specification scope review and preserve the decision with the estimate revision.

Frequently asked questions

What starts a firestopping penetration takeoff review?

Start with the controlling plans, schedules, details, and specifications, then define the full item population before extending cost.

How should unclear scope be handled?

Record the assumption, current estimate treatment, responsible reviewer, and the source needed to resolve it.

What should remain with the estimate?

Keep the quantity record, source references, scope assignments, estimate revision, and approved disposition together.
