Houston static control floors, built to ANSI/ESD S20.20
Aerospace ESD requirements usually arrive as contract language flowed down from a prime, not as a building code, so in Houston the audience for your resistance records is somebody else's auditor. The record here shows commercial space/aerospace, medical device/pharma cleanrooms.
The static sensitive work in Houston
Aerospace capacity in Harris County is what puts static control on the specification here. Each operation names where it was verified.

NASA's 240-acre Exploration Park at Johnson Space Center is due to complete Q4 2026, and NASA has a separate $300 million infrastructure-and-revitalization contract underway across Johnson Space Center facilities.

The customer is the auditor
An aerospace program in Houston treats the floor's qualification and reverification records as controlled documents, which changes what has to be handed over more than it changes the floor.
The document behind a Houston job
ANSI/ESD S20.20-2021 is the one worth reading first for work like this. Sets the requirements for an ESD control program, and with it the system level thresholds a qualified floor has to support.
What it actually governs
S20.20 is a program standard, not a product standard. It tells an organisation that handles ESD sensitive electrical or electronic parts how to run a control program: what has to be qualified, what has to be verified, and how often. Flooring is one item inside that program, which is why the standard sets a system threshold rather than a floor specification.
Questions from Houston
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.
Do you handle the whole job in Houston or just the coating?
The whole job: removing what is down, preparing the slab, the grounding network, the system itself and the cure schedule around your operation. Prep and grounding are where most of the work is. How it runs.
Is Houston inside your normal service area?
Yes. Harris 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.
