CFI Estimating, Layout & Planning

Question 1

When estimating carpet for a room with multiple pattern seams and cuts, what waste factor is most commonly added above net square footage?

Accepted Answer

10–15%

Answer

A 10–15% waste factor is standard for carpet with pattern matching and multiple seam cuts to account for repeat alignment and edge trimming.

Question 2

For a solid hardwood floor installation in a straightforward rectangular room with no pattern, what waste factor is typically recommended?

Accepted Answer

5–10%

Answer

5–10% waste is standard for solid hardwood to account for end cuts, grading culls, and layout offcuts.

Question 3

When planning a tile layout, what is the generally recommended minimum tile width at walls to avoid an unbalanced appearance?

Accepted Answer

One-half of a tile width

Answer

Layout should be planned so that border tiles are at least half a tile wide, preventing narrow slivers that look unbalanced and are structurally weak.

Question 4

A room measures 12 ft × 15 ft. Each box of LVP covers 18 sq ft. Adding 10% for waste, how many boxes are needed?

Accepted Answer

11 boxes

Answer

12 × 15 = 180 sq ft; 180 × 1.10 = 198 sq ft; 198 ÷ 18 = 11 boxes exactly.

Question 5

What is the primary reason that carpet seams should be oriented perpendicular to windows and primary light sources?

Accepted Answer

To make seams less visible by aligning pile direction with light

Answer

Running seams perpendicular to light causes pile to lay toward the viewer, making the seam shadow disappear rather than highlight it.
