The opportunity

Maricopa County is one of the fastest growing counties in the United States, leading to a substantial increase in the caseload of the Superior Court, demanding additional judicial positions, courtrooms and administrative space.  

The solution

In order to accommodate the needs of Maricopa County, Gilbane is managing the construction of a 723,000 GSF, 16-story Court Tower nestled in the center of Downtown. The new tower provides 32 courtroom sets and includes central juror assembly; secure central underground parking for county court judges, tunnels and pedestrian bridges, clerk and office support, and collegial judicial chambers. Designed as a 100-year LEED Silver building, the flexibility of courtroom types, juror seating, mechanical systems, technology and A/V and security systems is critical to the success of the construction project. The court tower includes extensive security features, together with an in-custody tunnel tied into the existing central campus.

  • Full-scale mock-ups constructed to enable judges to experience sight lines and flooring surfaces, resulting in changes to millwork and flooring systems
  • Developed wood-frame concrete floor system for raised platforms, allowing low-voltage systems to pass through the well; provides accessibility to low-voltage systems and cost-savings from typical access flooring system
  • Extensive, team-based value analysis consistent through design, resulting in cost-savings of $30M
  • Structural system analysis of concrete vs. structural steel identified that concrete construction would add 10 – 11 months to the schedule and cost $3 - $4M more
  • Outstanding subcontractor relationships with design-assist trades: structural steel, precast, M/E/P/FP, exterior metal cladding and glass and glazing resulting in early design packages; extensive off-site prefabrication will relieve stacking of trades and increase site safety
  • Shop-drawings for precast and structural steel complete before design is 50% complete
  • Close coordination with millwork subcontractor to ensure that all millwork required for the project will be shipped at the same time and that onsite temporary enclosures to control dust are erected before onsite work begins
