The preliminary estimate of ready mixed concrete produced in March 2014 is 22.4 million cubic yards, 6% higher than in March 2013. The estimated production for the first quarter of 2014 is 57.6 million cubic yards, 3.2% higher than that during the same period in 2013. Based on first quarter production and trends in the last 20 years, the projected production for 2014 is 310 million cubic yards with a margin of error of ±17 million cubic yards (6%). As might be expected, weather had a significant impact on production in the first quarter in many regions of the U.S.
