Commercial Outside Plaza Lighting in Great Neck, NY. Our electricians preformed multiple core drill holes that ranged from 1 inch to 6 inch. We stubbed up conduit in multiple places to create lighingt fixtures in cinder blocks, rebar, and concrete walls. These holes went through over a foot of concrete going through the outside plaza floor leading to the building parking structure. We then placed conduit following architecture drawings. Our placement and our excellence to preforming jobs to the letter, puts us ahead of the game. JMEC will always deliver what is contracted and beyond!!!
