Centuri crews are advancing safety-driven pipe replacement programs across North America.

Approximately 67 percent of the awards are for new work, including new strategic bid awards, with the remaining 33 percent for renewals of existing customer Master Service Agreements (MSAs). The work spans modernization of natural gas distribution infrastructure across the Midwest and Northeast, including securing a new major geographic area with a longstanding North American utility client. Additional awards include replacement of cast iron pipe in a populated urban center on behalf of an existing customer, an MSA renewal to support state-approved infrastructure modernization for a multi-decade client, and new industrial project work for an electric generation and transmission cooperative in the Midwest.

"We're starting the year strong, achieving over $1 billion in bookings with a continued focus on strong project delivery and work execution," said Centuri President and CEO Christian Brown. "Our most recent awards are a continued testament to the comprehensive capabilities, reputation, and scale that differentiate Centuri as a trusted partner to our utility and energy clients."
