301 W. Jefferson Administration Building – Maricopa County, AZ

The renovation of the 240,000 sq. ft. Maricopa County Administration Building located at 301 W. Jefferson Phoenix, AZ. A multi-phased, fully occupied renovation of the existing Maricopa County Administration Building to consolidate current tenants and relocate several County departments into the building redesign.
The project, referred to as the “Re-Stacking Project,” enables upon completion Maricopa County to consolidate multiple county agencies into the redesigned building. The “Re-Stacking Project” is aligned with the 225 W. Madison Project which was completed in Q1 2020 and is now the home of the Maricopa County Attorney, previously housed at 301 W. Jefferson.

The scope includes updating building services, including energy efficient lighting, mechanical distribution, IT Communication and Audio-Visual systems for the entire building. The project provides a consistent layout philosophy on each floor providing ease of wayfinding for the public and employees alike.

The CMAR construction contract was awarded to Layton Construction, with the architectural design delivered by Dekker Perich Sabatini.

Inspired Networks was contracted by Maricopa County’s Facilities Management Division (FMD) for the design and delivery of the communication and audio-visual systems.
