The National Electrical Contractors Association (NECA) published a report, Project Peak Workforce Report, in 1987 that used 120 projects to predict the peak number of workers for jobs based on the documented actual work hours for different types of electrical projects. However, the NECA report has become outdated and no longer represents the current construction scenario.

The present publication is an update to the original NECA report, using current project data. The primary purpose of this publication is to assist electrical contractors with estimating the peak number of workers that can be expected on various electrical construction projects, including commercial, industrial, and institutional.
