The purpose of this report is two-fold. First, the report is designed to assist electrical contractors in evaluating the special job conditions found in multi-story building construction that cause an increase in the cost to install the electrical systems. Second, the report offers recommended estimating practices that will insure recovery of these added costs.

This report is an update to an existing NECA study and survey from the 1970's. While the results of the original report have essentially been left intact, a new section has been added to further explain the impact of project size on labor productivity.
