AT&T Central Office—Plano, IL

The job was to take a 1950’s building with two foot thick walls, located underground, houses emergency telephone equipment, and is capable to withstand a nuclear blast and upgrade it.

The job called for adding new telephone equipment in addition to the existing equipment which was not designed to handle the additional load. Add to this, the original mechanical equipment which was still working had to be replaced. The existing temperature control system, required replacement with more contemporary technology.

Another concern was the building did not have any city water service and the existing fire protection system was not big enough to handle anything anymore. Plus the electrical system was maxed out and the main transformer was in need of replacement. But no system can be shut down. Not ever.
