F-numbers on the slab, the same day.
ASTM E1155 is the method for floor flatness (FF) and floor levelness (FL) F-numbers on concrete slabs. Specs for data centers, warehouses, and defined-traffic industrial floors name the numbers. We measure the slab to that method and report the F-numbers the contractor and the owner’s rep can act on.
Timing matters. A pour that misses FF/FL is cheaper to correct before the next placement or before racks and raised floor go down. We report the same day when access allows, with the lines and sample locations the standard requires — not a walk-around opinion.
Phoenix and the Valley, including metro Phoenix data center campuses already on our project list, plus warehouse and industrial slabs. Office: 7931 E Pecos Rd, Suite 203, Mesa. Weekend pours are normal; call 480-988-6602. 24/7 including weekends.
Veteran-owned. If the same job also needs special inspection or NDT, that is the same company — one point of contact.
