Flatiron, a subsidiary of HOCHTIEF, is embarking on projects across the golden state.
An engineering-led global infrastructure group, Flatiron's diverse projects around California are estimated to total around $704 million.
Upgrading the state's infrastructures will make valuable additions to communications, transportation and the state's supply chains, helping to further make California a vital hub.
Caltrans Middle-Mile Broadband Network Costing $191m
The California Department of Transportation has approved the award of two preconstruction services contracts to a Flatiron-led joint venture with LTS Managed Technical Services (Ledcor) to construct middle-mile broadband infrastructure, which will help provide affordable, accessible broadband infrastructure to enable last-mile network connectivity throughout California.
This Construction Manager/General Contractor (CM/GC) project will bring high-speed broadband to homes and businesses across the state.
The District 5 project focuses on areas in San Luis Obispo and Santa Barbara counties. The construction team will face difficult rocky soil conditions for about half of the 208-mile project route. The California Coastal Commission controls most of the route along State Highway 1, with large stretches in "critical coastal areas" requiring significant biological and aquatic mitigation. The project also runs via historic bridges, major river crossings, railroad lines, canals, and overpasses.
The District 2 project focuses on communities in Lassen, Plumas, Shasta, Siskiyou, and Tehama counties. The 250-mile project path requires 48 bridge crossings and difficult installation in sloping rocky terrain near the Rock Creek Reservoir Dam. Flatiron will assist Caltrans with alignment optimization, constructability studies, environmental permitting, and right-of-way verification.
East Bay Municipal Utility District Project Costing $237m
Flatiron has been chosen by the East Bay Municipal Utility District (EBMUD) to deliver projects that will allow EBMUD to satisfy its long-term promises to provide clean drinking water to communities in and around Oakland, California.
The contract covers both the Upper San Leandro Water Treatment Plant and Maintenance and Reliability project and the Sobrante Water Treatment Plant Chemical Systems Safety Improvements project.
Flatiron will upgrade existing facilities while also building new ones, including improvements to the raw water control valve and flocculation and sedimentation basins, replacement of the existing below-grade chlorine contact basin, and replacement, rehabilitation, and addition of tanks, pumps, and pipelines associated with the reclaim and solids handling system.
This new contract further strengthens Flatiron's partnership with EBMUD. Flatiron is currently working with EBMUD on the $31 million Maloney Pumping Plant project and the $267 million Orinda Water Treatment Plant project.
California Highway Improvements Project Costing $276m
The Caltrans has chosen a Flatiron-led joint venture with Teichert to implement a $204.8 million project in Yolo County, California, to improve safety, reduce traffic congestion, and increase travel-time predictability along the I-80 and U.S. 50 corridor.
As the only freeway connection between the San Francisco Bay Area and the Sacramento metropolitan area, I-80 is critical for regional and interregional transportation.
Two bridges will be widened, and nine will be modified during construction. More than 100,000 cubic yards of concrete pavement will be required to rehabilitate more than ten kilometers of roadway. The project will contribute to environmental sustainability by improving traffic flow through cutting-edge traffic monitoring and traveler information systems.
In partnership with the City of Temecula, California, Flatiron has begun work on the $71.5 million I-15 French Valley Parkway Phase II project. By improving traffic flow efficiency, the project will reduce traffic congestion, increase safety, and contribute to environmental sustainability.
This project, the second of three phases, calls for constructing collector and distributor lanes along northbound I-15 from the Winchester Road Interchange to the I-15/I-215 Junction. The project also includes:
