San Antonio static control floors, built to ANSI/ESD S20.20
Airframe and avionics work in San Antonio inherits its static control obligations from a customer rather than from a building code, which changes what has to be retained. Measured here: aerospace MRO, automotive electronics, data centers.
San Antonio, and what gets built here
Aerospace capacity in Bexar County is what puts static control on the specification here. Each operation names where it was verified.

The customer is the auditor
An aerospace program in San Antonio 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 San Antonio job
ANSI/ESD STM97.1-2025 is the one worth reading first for work like this. System resistance measurement of a person, their footwear and the floor as one circuit. This is the test behind the S20.20 ceiling.
A 2025 edition, replacing 2015
The current edition is 2025 and it supersedes the 2015 one. If your program document cites the 2015 edition it is not wrong, it is simply on an older revision, and it is worth checking what changed before your next audit.
Questions from San Antonio
Our ESD requirement came from a customer contract, not a code. Does that change anything?
Do you handle the whole job in San Antonio 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 San Antonio inside your normal service area?
Yes. Bexar 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.
