CSLB C-27 Landscaping ContractorPlanning and EstimatingMedium
A C-27 contractor is bidding on a project that involves removing existing concrete pathways and installing new permeable pavers. The client's specifications require that all removed concrete be diverted from landfills and recycled. What is the MOST significant cost factor for the contractor to consider for this aspect of the project?
- AThe aesthetic quality and color of the recycled concrete aggregate.
- BThe labor cost for breaking up the existing concrete pathways.
- CThe availability of equipment for installing permeable pavers.
- DThe transportation costs to a certified concrete recycling facility.
Show answer & explanationAnswer & explanation
Correct answer: D. The transportation costs to a certified concrete recycling facility.
While breaking up concrete requires labor, and paver installation requires equipment, the mandate to recycle requires hauling the heavy concrete debris to a specific, certified facility. The transportation costs, especially for large volumes and potentially distant facilities, are typically the most significant financial implication for concrete recycling.
Why the other options are wrong
- A. The aesthetic quality of recycled aggregate is not relevant to the cost of recycling the removed concrete.
- B. Labor for demolition is a direct cost, but transportation of heavy materials over distance for recycling often exceeds it.
- C. Paver installation equipment is for the new work, not the recycling of old concrete.
Recycling & Disposal Costs
The expenses incurred for properly disposing of or recycling construction debris, especially when specific diversion mandates are in place, often heavily influenced by transportation distance and tipping fees.
- Mandatory recycling increases project complexity and cost.
- Transportation of heavy waste is a major cost driver.
- Tipping fees at recycling facilities can vary.
Memory trick: Recycling waste is great, but don't forget the truck and gate.
