A contract unit price for pressure grouting is $82/lf. Approved added work measures 145 lf. What added payment is due?
Correct Answer
B) $11,890
Added payment is 145 lf x $82/lf = $11,890. Other choices use 100 lf, 133 lf, or $100/lf rather than the stated unit price.
Why This Is the Correct Answer
Added payment is 145 lf x $82/lf = $11,890. Other choices use 100 lf, 133 lf, or $100/lf rather than the stated unit price.
Why the Other Options Are Wrong
Option A: $8,200
unit-price addition, choice a: $8,200 is wrong because $8,200 prices 100 units at $82.
Option C: $10,890
unit-price addition, choice b: $10,890 prices 132.8 units at $82.
Option D: $14,500
unit-price addition, choice d: $14,500 is wrong because $14,500 prices 176.83 units at $82.
Memory Technique
Remember unit-price addition as "base, adjustment, final unit"; the last unit should read $11,890.
Reference Hint
Open Construction Project Management, 5th Ed. (2022); use the index entry or section for "Unit-price added work" to confirm that Added payment is 145 lf x $82/lf = $11,890.
