Tiernan & Patrylo, Inc. was selected by Williams Communications to construct several POP Centers throughout the United States. These POP sites are extremely complex, both electrically and mechanically. These facilities are typically concrete or masonry construction, house environmental air units, special air suppression systems, emergency generators for back-up power, as well as UPS  systems to assure a clean power supply.

Williams Communications is North America’s only exclusively fiber-optic network and the largest independent source of end-to-end integrated business communications solutions-data, voice or video.
