| Question | Direct answer |
|---|---|
| What projects? | New office and expansion IT, network upgrades, Microsoft 365 and server migrations, PC refreshes and multi-site rollouts. |
| Who runs them? | BTI Communications Group, LTD. project engineers from Santa Fe Springs. |

| How is it priced? | A written, itemized scope after a walk-through. Financing at 3.99% for qualified buyers, subject to credit approval. |
| What happens after? | The site moves into managed IT support with the same team. |
Many project failures in Irvine offices come from handoffs. A low-voltage contractor leaves, a landlord circuit is late, a cloud tenant is still in a former employee's name, and nobody owns the weekend of the move.
BTI writes a scope you can read, does the work, tests it as a business test (can users log in, print, open the door, join Teams), and then supports it. You are not left with a folder of unmarked patch cables and a voicemail.
Cabling design can be coordinated with network installation. Wireless design may use the Orange County Meraki page. Phones use the Orange County business communication page.
The project list is similar across industries; the constraints are not.
Weekend cutovers so client work is not interrupted, with email and document access tested before Monday.
Production equipment, segmented networks and change control during moves and upgrades.
Landlord rules, shared risers and after-hours access windows built into the schedule.
Projects bought through GSA, CMAS or TESMA, with documented acceptance testing.
Wi-Fi on the floor, scanners and label printers moved and tested with the office systems.
We make sure no carrier, landlord or application dependency becomes a cutover surprise. IBC and Spectrum buildings in particular often have shared risers, reserved telecom closets and access windows that have to be booked.
Our Southern California office is at 12155 Mora Dr, Units 1 and 2, Santa Fe Springs, CA 90670. Most support is handled remotely, and our engineers are about 30 miles from Irvine, typically 30 to 40 minutes by the 5 or the 405, whenever on site work is needed.
We also support nearby Tustin, Costa Mesa, Newport Beach, Lake Forest and Santa Ana. For county-wide services, see the Orange County hub.
