Which quick estimate method is more accurate according to the manual?

The method of multiplying single outlet costs by total outlets is considered more accurate according to the manual because it utilizes specific unit costs that are generally well-documented and consistent across various projects. This approach directly correlates to the number of outlets needed and factors in the cost associated with each individual outlet, leading to a more precise overall estimate.

By relying on established costs per outlet, this method minimizes the potential for varied interpretations or excess assumptions that might arise with more generalized methods. It also allows estimators to quickly calculate a total based on tangible data, making it effective for quick assessments of electrical installation costs. This level of detail can provide a clearer budget perspective than broader approaches, enhancing accountability and precision in the estimating process.
