CSLB C-27 Landscaping ContractorPlanning and EstimatingMedium

A C-27 contractor is bidding on a commercial landscape project that includes a requirement for a 'Certified Arborist Report' for all existing trees to remain on site. The cost for this report is not explicitly listed in the client's Request for Proposal (RFP). What is the contractor's BEST course of action during the bidding phase?

  1. AInclude a provisional sum for the report, clearly stating it in the bid submission.
  2. BExclude the cost, assuming the client will provide the report or cover the expense separately.
  3. CEstimate the cost based on past projects and absorb it into the overhead.
  4. DObtain a quote from a certified arborist and include it as a line item in the bid.
Show answer & explanation

Correct answer: D. Obtain a quote from a certified arborist and include it as a line item in the bid.

If a required item like a Certified Arborist Report is specified but not priced or provided by the client, the contractor must obtain a direct quote for that service and include it as a clear line item in the bid. This ensures accuracy, transparency, and avoids absorbing unexpected costs.

Why the other options are wrong

  • A. While a provisional sum is an option, a direct quote for a specific, known requirement is more accurate and professional than a general placeholder.
  • B. Excluding a required cost is risky and can lead to financial loss or project delays if the contractor is later obligated to provide it.
  • C. Estimating and absorbing the cost into overhead without a firm quote is speculative and can lead to underpricing the project, especially for specialized services.

Bid Item Costing (Unpriced Requirements)

When a Request for Proposal (RFP) specifies a required service or item but does not provide details for pricing or procurement, the contractor must proactively obtain a direct quote and include it as a distinct line item in their bid to ensure accuracy and transparency.

  • Never assume unpriced requirements are free.
  • Seek direct quotes for specialized services/items.
  • Include as a clear line item, not hidden in overhead.

Memory trick: If it's required but not priced, get a quote, make it a line item.
