This guide details the Labor Efficiencies Design implemented in Xactimate, a software developed by Verisk. It outlines the features related to labor efficiencies, which were introduced to address customer concerns regarding the accurate estimation of labor costs across various job sizes and conditions. The document explains the evolution of labor efficiency models, including the introduction of a new category for Large Restoration/Remodel jobs. It describes the factors affecting labor efficiency, such as job size, complexity, and accessibility, which are critical for accurate pricing. The guide also discusses the importance of selecting the appropriate efficiency model based on specific job conditions and outlines the minimum labor charges that apply to various tasks. Additionally, it emphasizes the need for estimators to consider peripheral tasks and their impact on overall labor costs. The document serves as a comprehensive resource for understanding the labor efficiency architecture within Xactimate and the implications for pricing and job estimation.
