The Northwest Wall and Ceiling Bureau, in cooperation with several other wall and ceiling industry associations in the West, has published a study focusing on the impacts on labor productivity on steel framing and the installation and finishing of gypsum wallboard.

This study was the first one investigating external impacts to labor productivity in the wall and ceiling industry. It measured the impact of 38 variables on 226 separate projects. The study found that unexpected labor congestion, fragmentation, overtime and added shift work negatively impacted labor productivity.

Because labor productivity is the single greatest variable affecting the construction contractor’s cost of production and profitability, the findings of this study can help wall and ceiling contractors get compensated for their productivity losses due change orders and other factors out of their control.

The authors of the document are Gerald H. Williams, Ph.D., P.E., of Construction Research Inc., Portland Ore., and Timothy R. Anderson, Ph.D., of Portland State University, Portland, Ore. The following associations participated in the study with NWCB: Northwest Wall and Ceiling Contractors Association, based in Seattle; Northern California Drywall Contractors Association, based in San Jose, Calif.; Western Wall and Ceiling Contractors Association, based in Orange, Calif.; and Associated Wall and Ceiling Contractors of Oregon and Southwest Washington, based in Portland, Ore.

A summary of Impacts to Labor Productivity in Steel Framing and the Installation and Finishing of Gypsum Wallboard and an online order form are available The cost of the publication is $299. Members of the participating associations may purchase it for $199. For more information, call (800) 524-4215 or go
