ESD flooring in Waco, to 2.5 x 104 to 1.0 x 106 ohms
Aerospace ESD requirements arrive as contract language flowed down from a prime, so in Waco the audience for your resistance records is somebody else's auditor. The record here: aerospace/avionics manufacturing.
Waco, and what gets built here
Airframe, avionics and space hardware work around Waco is where the requirement originates, each operation against a named source.
L3Harris' Waco facility operates its Skyraider II Center of Excellence converting aircraft
L3Harris' Waco facility operates its Skyraider II Center of Excellence converting aircraft for Air Force Special Operations Command's Armed Overwatch program, and may add 300 employees over five years; in April 2026 the same Waco facility delivered a modified next-generation research aircraft to NASA five weeks ahead of schedule.
The customer is the auditor
On a Waco program the deliverable is evidence as much as coating, because the records have to survive an audit run by somebody outside your building.
The document behind a Waco job
ESD TR53-01-22 is the one worth reading first for work like this. The technical report for compliance verification testing of ESD control items in service. The document your periodic floor recheck follows.
Qualification is day one, verification is forever
A floor is qualified once, when it goes in. TR53 is about everything after that: the recurring checks that prove the floor is still doing its job while people walk on it, clean it and wheel carts across it.
Questions from Waco
What records should we insist on at closeout?
Product data for the system installed, the surface preparation profile, moisture readings taken before installation, a grounding drawing, and the resistance readings mapped to floor locations. Name that package in the specification or it tends not to exist.
What do you need from us to price a Waco job?
Square footage, what is on the slab now, the resistance band your specification calls for, and the hours the space can be handed over. Four answers and we can price the actual room instead of quoting a range.
Is Waco inside your normal service area?
Yes. McLennan County is covered on the regular Texas schedule, so a job here does not carry a travel premium the way a one off out of state trip would.
