Course outline
Wall base, transitions, stairs and counts
Take off wall base in linear feet from each room's perimeter, less door openings, and count inside and outside corners separately. Count a transition at every place two different floors meet, measured in linear feet by type. Count stair treads, risers and landings individually. These linear and count items carry a lot of labor per unit — estimate them as their own lines, never as a percentage of area.
After this lesson you can
- Take off wall base by room perimeter with openings deducted
- Find and count every transition by type
- Quantify stairs and small counted items that drive labor
How do you take off wall base?
- Separate by base typeRubber base in two heights is two conditions; sheet vinyl flash cove and tile base are different installations entirely. Use the base codes from the finish schedule.
- Measure room perimetersRun base along every wall that gets it — including around columns, chases and island walls — and stop at door openings.
- Deduct openingsSubtract door and cased openings. Don't deduct small breaks, which cost cutting time anyway.
- Count cornersInside and outside corners are separate counts. Preformed corners are material; wrapped or mitered corners are labor.
- Check what's excludedNo base behind casework or under wall tile; confirm who does base at elevators, stairs and exposed structure.
- Rooms
- 20 offices at 12 × 14 ft
- Door opening
- One 3-ft door per office, opening to an LVT corridor
- Base
- 4-inch rubber base (RB-1)
- Office floor
- Carpet tile
- Perimeter per office: 2 × (12 + 14) = 52 LF.
- Less the 3-ft door: 52 − 3 = 49 LF of base per office.
- Base for all offices: 49 × 20 = 980 LF.
- Inside corners: 4 per office × 20 = 80 corners.
- Carpet-to-LVT transitions: one per door × 20 = 20 transitions, or 60 LF.
- Base: 52 LF perimeter − 3 LF door = 49 LF
- Corners: 4 inside corners
- Transition: 1 at the door, 3 LF
× 20 offices = 980 LF of base, 80 corners and 60 LF of transitions.
Where do transitions go?
A transition is needed wherever two different floors meet, wherever a new floor meets an existing one, and at many edges. Find them by walking the finish plan boundary by boundary:
- Door openings between rooms with different floors — usually the most common location.
- Material changes in open areas — a carpet field meeting an LVT walkway, or a lobby tile border.
- Height changes — thicker tile meeting thinner resilient flooring needs a reducer, not a flat strip.
- Existing-to-new boundaries on renovation work.
- Exposed edges — at elevator thresholds, floor-to-stair edges and open sides.
- Expansion or control joints that the flooring must honor.
Take off transitions in linear feet by type — carpet-to-resilient, reducer, T-molding, edge trim — because each is a different product and installation.
How do you quantify stairs?
| Item | Take off as | Watch for |
|---|---|---|
| Treads | Count, by width | Integrated nosing vs. separate nosing; visually contrasting nosing requirements |
| Risers | Count, by width and height | Matching or contrasting material |
| Nosings (if separate) | Count or LF | Profile and adhesive specified |
| Landings | SF, as their own area | Landing edge treatments |
| Stringers / skirts | LF | Whether base continues up the stairs |
Other counts that drive labor
- Rooms — every room is a setup, a cut layout and a clean-up.
- Floor boxes and penetrations — each needs a precise cut.
- Columns in the field — cutting around them costs time and material.
- Thresholds and door stops that must be removed or reset.
Frequently asked questions
How do you take off wall base?
Measure the perimeter of each room that gets base, subtract door and cased openings, keep different base types separate, and count inside and outside corners. Total the linear feet by base type.
How many transitions does a flooring job need?
One at every boundary where two different floors meet, plus new-to-existing boundaries, height changes and exposed edges. Walk the finish plan boundary by boundary and take them off in linear feet by type.
How are stair treads and risers estimated?
Count treads and risers individually by width, count or measure separate nosings, and measure landings as their own area.
Key points
- Base is perimeter less openings, by base type — plus a corner count.
- Every boundary between different floors is a transition, by type.
- Stairs, rooms and penetrations are counts that carry real labor.
Linear and count lines stay separate
In IntelBid's built-in takeoff (for desktop for now), base and transitions are Linear conditions and corners, floor boxes and treads are Counts, each under its own finish code, so none of them hide inside an area. Extract the measured sheets to Bid Docs and change the new file's category to QTO, and Auto Draft drafts base and transitions as their own linear-foot lines, priced from the last unit price you used for that scope, instead of burying them in a per-SF number.
