CSLB C-27 Landscaping ContractorPlanning and EstimatingMedium
A C-27 contractor is estimating costs for a new landscape project that involves significant grading and the removal of existing concrete pathways. The contractor anticipates generating 20 cubic yards of concrete debris and 10 cubic yards of excess soil. The local landfill charges $75 per cubic yard for concrete disposal and $40 per cubic yard for soil disposal. What is the total estimated disposal cost?
- A$1,150
- B$1,900
- C$2,300
- D$1,500
Show answer & explanationAnswer & explanation
Correct answer: B. $1,900
Calculate concrete disposal cost: 20 cu yds * $75/cu yd = $1,500. Calculate soil disposal cost: 10 cu yds * $40/cu yd = $400. Total disposal cost = $1,500 + $400 = $1,900.
Why the other options are wrong
- A. This is an incorrect calculation; possibly adding the rates and multiplying by total volume, but with an error.
- C. This is an incorrect calculation; possibly adding all values incorrectly or a miscalculation.
- D. This only accounts for the concrete disposal cost ($1,500).
Debris Disposal Costing
The process of estimating the expenses associated with removing and legally disposing of various types of waste generated during a landscape project.
- Costs vary by material type and volume.
- Landfill fees, hauling, and recycling impact costs.
- Proper disposal is legally mandated.
Memory trick: Each waste type gets its own volume times rate, then sum them all.
