Masons need to calculate their production rates accurately in order to make a fair profit when installing NRG.
For the new NRG 8", an experienced mason new to the NRG 8" reports that he and another mason with a block tender/laborer averaged about 400 NRG 8" units per day total for the three person crew.
That project used 3500 NRG 8" ground face units, in a fully reinforced and fully grouted wall.
You can click on the above link and watch two masons lay the NRG 10" at the rate of about one unit per minute,or 60 units per hour.
Steve Richard teaches masonry arts at Alfred State College, School of Applied Technology, and has over thirty-five years experience as a professional mason.
Steve erected a fire station with NRG block in Genesee, PA, that is highly reinforced (as an emergency building, it is similar to those that meet California seismic requirements).
He estimates his two person crew installed about 175 NRG 12" blocks per day in the fully reinforced NRG building. (NRG 12" is the mother of all 12" blocks, as a 135 pcf block comes in at around 66 lbs).
For a lightly reinforced NRG 12" building, Steve estimates production on straight-run walls to be between 250 and 300 blocks per day, for a two man crew.
Tip from Steve: "When laying the NRG, do not tap it to align it. If you need to adjust the alignment, it is better to pick up the block, so the weight is off the insert, and reset it carefully." (Since the insert is engaged when you set the block, it will knock the block out of alignment if you tap it to align it.)
So, the NRG block requires careful first placement for maximum production.
NRG's reward is that NRG can win back masonry jobs from non-masonry systems that are gaining market share.
NRG hopes that masons everywhere jump on board with NRG, since it can help grow your business.
