FAQ
What is Cruxi?
Cruxi is a regulatory and compliance marketplace that helps commercial facilities find qualified partners. We work with 200+ firms across the U.S. and share your request only with matched providers.
Why should I use Cruxi?
Quality + reliability: we work with known partner firms and match based on your location and scope. Better pricing: getting 2–3 bids creates competition, which often reduces cost versus sourcing a single quote (savings vary by project).
What does this typically cost?
Pricing depends on panel count, voltage level, documentation quality, and whether on-site data collection is needed. You’ll receive bids based on your exact scope.
Who is this for?
This is for commercial and industrial facilities (plants, data centers, hospitals, campuses). We don’t support residential/home projects.
Do I need existing drawings?
No — but existing one-lines, panel schedules, and photos help providers quote accurately and faster.
Remote vs on-site?
It depends on documentation quality and required equipment access. You can select remote only, on-site OK, or either.
Can you include medium voltage?
Yes — select “Medium voltage included” so we can match providers that cover MV work.
How fast will I get bids?
Typically 1–3 business days for initial bids. Rush timelines are possible depending on scope and documentation.
