Why TESIM
Clear scope. Practical coordination.
Define the package
Drawings, equipment responsibilities and field conditions come first. Agree inclusions, exclusions and the installation boundaries before work begins.
Current on the code
Every installation is built to the National Electrical Code and we stay current each cycle. On commercial electrical work that isn’t a formality — it’s the whole job.
Coordinate around the project
Discuss equipment deliveries, trade interfaces, site access and any shutdown windows so the electrical package fits the construction plan.
Local & responsive
Based in Lakeway and working across all of Texas — close enough to walk the site, answer the phone, and coordinate directly with your team.
Straight about our scope. We install, terminate, and connect this equipment. We don’t design, engineer, commission, manufacture, or service it — that stays with the engineer of record, the manufacturer, and the commissioning agent.
Installation scope, equipment responsibilities, project qualifications and field conditions are reviewed before work is agreed.
