CSLB C-33 Painting & DecoratingPlanning and EstimatingEasy

A painting contractor is reviewing a bid for a project that includes a 'Unit Price' for additional work beyond the initial scope. If the client requests an additional 500 square feet of wall painting, and the bid specifies a unit price of $2.50 per square foot for wall painting, what is the cost for this additional work?

  1. A$1,500
  2. B$1,250
  3. C$1,000
  4. D$2,000
Show answer & explanation

Correct answer: B. $1,250

The cost for additional work is calculated by multiplying the additional quantity by the specified unit price. In this case, 500 sq ft * $2.50/sq ft = $1,250.

Why the other options are wrong

  • A. Incorrect calculation; this would be $3.00/sq ft for 500 sq ft.
  • C. Incorrect calculation; this would be $2.00/sq ft for 500 sq ft.
  • D. Incorrect calculation; this would be $4.00/sq ft for 500 sq ft.

Unit Price in Bidding

A predetermined cost per unit of material, labor, or service, used to calculate costs for changes in project scope or quantities.

  • Simplifies pricing for add-ons or deductions.
  • Eliminates the need for new negotiations for minor changes.
  • Often used in contracts where quantities may fluctuate.

Memory trick: Units times Price equals the total cost, quick and precise.
