Awards: I-80/U.S. 50; I-15; EBMUD; Caltrans middle-mile broadband infrastructure
Value
: $617 million
Location: California
Clients: California DOT, East Bay Municipal Utility District, City of Temecula, California.

As an example of public funding resiliency in the face of broader construction financing concerns, Flatiron has won four California agency-led projects worth a combined $704 million.

I-80 and U.S. 50 corridor – $204.8 million

Caltrans, the state’s DOT, tapped a Flatiron-led joint venture with Teichert to deliver a $204.8 million project along the I-80 and U.S. 50 corridor in Yolo County to enhance safety and reduce traffic.

A weekend escape route for Bay Area residents looking for recreation in Lake Tahoe and the Sierra Nevada Mountains, it’s the only freeway connection between San Francisco and Sacramento, and links to the I-505 connector for travelers headed north on I-5.

The eastbound lanes on Friday evenings and westbound lanes on Sunday afternoons are routinely choked with traffic. Flatiron said the project will contribute to environmental sustainability through more efficient traffic flow via traffic monitoring and traveler information systems.

Rehabilitation of more than 10 miles of roadway will require more than 100,000 cubic yards of concrete pavement. The plan aims to widen two bridges and modify nine others.

I-15 French Valley Parkway Phase II – $71.5 million

Flatiron also kicked off the $71.5 million I-15 French Valley Parkway Phase II project in Southern California in collaboration with the City of Temecula.

With more than 200,000 vehicles traveling on the roadway daily, this highway section is considered among the top ten worst-congested freeway segments in the U.S., Flatiron said. In July 2019, Temecula received a $50 million U.S. Department of Transportation Infrastructure & Rebuilding America Grant to support the project.

The second of a three-phase improvement plan, this project calls for constructing collector and distributor lanes along northbound I-15 from Winchester Road Interchange to the I-15/I-215 Junction.

Other project highlights include construction of a new bridge over the I-215 Freeway, widening two bridges and constructing 40-foot-high retaining walls. Flatiron completed Phase I of improvement plan in 2013.

East Bay Municipal Utility District water treatment projects – $237 million

Flatiron secured a $237 million contract for work at the Upper San Leandro and Sobrante Water Treatment Plants near Oakland.

East Bay Municipal Utility District selected Flatiron for a maintenance and reliability project at San Leandro and chemical systems safety improvements at Sobrante. San Leandro was built in 1927 and delivers water to the Oakland, San Leandro, San Lorenzo, Piedmont, Hayward and Castro Valley communities.

Without disrupting existing provision of drinking water, Flatiron will upgrade existing facilities and construct 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, according to a news release.

Caltrans middle-mile broadband network – $191 million

Caltrans awarded two preconstruction services contracts worth $191 million to a Flatiron-led joint venture with LTS Managed Technical Services, or Ledcor. The projects will create middle-mile broadband infrastructure for unserved and underserved California communities.

The District 5 project, in California’s Central Coast region, focuses on communities throughout San Luis Obispo and Santa Barbara counties. Through approximately half of the 208-mile project route, the construction team will face challenging rocky soil conditions. A majority of the route along State Route 1 is located within the jurisdiction of the California Coastal Commission, with large portions in locations deemed as “critical coastal areas,” requiring significant biological and aquatic mitigation. The route also crosses historic bridge structures, major rivers, railroad lines, canals and overpasses.

The District 2 project, located in far Northern California, focuses on communities throughout Lassen, Plumas, Shasta, Siskiyou and Tehama counties. The 250-mile project route requires 48 bridge crossings including the Pit River Bridge over Lake Shasta, plus challenging installation through sloping rocky terrain and near Rock Creek Reservoir Dam.
