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 is currently erecting 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 a two person crew should be able to install about 175 NRG 12" blocks per day in a fully reinforced NRG building.
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 it can win jobs from non-masonry energy efficient wall systems that are gaining market share.
We hope that masons everywhere embrace NRG, since it can play a key role in ensuring continued employment.
