The 14.7 million wage and salary workers who were members of unions in 2018 represented 10.5 percent of the U.S. workforce, down 0.2 percent year-over-year, a Bureau of Labor Statistics report confirms. The figure underscores a sustained union membership rate decline since 1983, the first year for which comparable worker data are available. BLS calculated a rank-and-file of 17.7 million workers that year, or 20.1 percent of the wage and salary workforce.

ACPA sees 2019 concrete highway pavement volume rising to 56.2 million sq. yd., up 7 percent from 2018 and representing the largest such watermark since 2012. “Looking back at the past two years, 2017 was challenging for paving volume, but 2018 projected volumes indicate a strong rebound,” ACPA CEO Gerald Voigt observed at a World of Concrete 2019 briefing.

Software unveiled at World of Concrete 2019 generates floor flatness and levelness figures from laser scan data, and visualizes wet or hardening concrete slabs’ high or low areas with elevation or deviation heatmaps, contours and grids. The new Rithm for Autodesk Navisworks version promptly delivers analysis reports compliant with ASTM E1155, Standard Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers. In contrast to the multiple-day process typical of current FF/FL measurement practice, developers cite the program’s capacity to reveal E1155 numbers in under 15 minutes.
