What is NOT one of the methods for determining the margin to apply to an estimate?

The method of using client feedback is not traditionally considered a primary method for determining the margin to apply to an estimate. Instead, margin determination typically relies on analytical methods and industry standards rather than subjective or informal input from clients.

The fee to general contractor (GC) ratio helps to quantify the relationship between the contractor's fee and the overall project costs, providing a more objective basis for margin setting. Market conditions give insight into how supply and demand dynamics can influence costs and profitability, allowing estimators to align margins with current project viability. The estimator's recommendation draws upon their experience and the specifics of the project to suggest a margin that reflects the risk and investment involved.

In contrast, client feedback, while valuable for understanding expectations and refining project objectives, does not directly inform the technical factors or calculations typically used to establish a margin on an estimate. Thus, it stands apart from the more formalized methods that help ensure estimates are competitive yet reflective of project realities.
