CSLB C-27 Landscaping ContractorPlanning and EstimatingMedium
A C-27 contractor is evaluating plans for a new landscape project that involves installing several large trees. The plans specify the species, size, and location of each tree. Before finalizing the estimate, the contractor discovers that access to some of the tree planting locations is restricted, requiring specialized equipment (e.g., a spider lift or crane) and additional labor for maneuvering the trees. How should this discovery impact the contractor's estimating process?
- ARevise the labor and equipment costs specifically for the affected tree installations, factoring in the specialized equipment, additional crew, and extended time.
- BSuggest to the client that smaller trees be used in the restricted areas to avoid specialized equipment costs.
- CProceed with the estimate assuming standard tree installation methods and address access issues as a change order if they arise.
- DIncrease the overall contingency percentage of the bid to cover potential unforeseen equipment and labor costs.
Show answer & explanationAnswer & explanation
Correct answer: A. Revise the labor and equipment costs specifically for the affected tree installations, factoring in the specialized equipment, additional crew, and extended time.
Specific challenges like restricted access requiring specialized equipment must be accurately quantified and included in the estimate. This is not an unforeseen risk for a contingency but a known condition requiring specific cost adjustments.
Why the other options are wrong
- B. Suggesting design changes is a client discussion, but the contractor's primary role is to accurately bid on the provided plans first.
- C. This is reactive and unprofessional; known conditions should be priced upfront.
- D. While a contingency is good for unknowns, this is a known, specific condition that can be quantified and should be directly accounted for.
Specific Condition Cost Adjustment
Modifying an estimate's labor, equipment, and material costs to account for known, unique site conditions or project requirements that deviate from standard installation methods.
- Applies to identified challenges, not general unknowns.
- Requires detailed breakdown of additional resources.
- Ensures accurate bidding and avoids future change orders for known issues.
Memory trick: Known hurdles get specific costs, not just general boosts.
