Building a Better Future Today

The Lower Olentangy Tunnel (LOT) project is a consent decree project in the city of Columbus, Ohio, that will improve water quality and reduce overflows from the sewer system into creeks and rivers. Granite is working at multiple locations for this project, which will create 17,000 feet of tunnel with multiple tie-ins to the main tunnel from the surface.

This project in Santa Clara County, California, is part of a larger collection of flood protection improvements under the Lower Berryessa Creek Flood Protection Project, which will provide new floodwalls, improved levees, and widened creek channels to accommodate high water flows. The project will also enhance and enlarge tidal and freshwater wetlands and riparian habitats. Upon completion of all project phases, nearly 2,500 homes and businesses will be protected from the threat of a 100-year flood event.

As part of the city's initiative to reduce the carbon footprint of City Hall by more than 15%, the facility is currently undergoing a complete air handling unit upgrade. This project will renovate a total of 16 different air handling units, 12 on the roof and four in the basement. The existing units were more than 40 years old and consisted of a single, large belt-drive fan. These required constant maintenance—replacing fan belts, changing outdated filters, and operating dampers by hand.

At Granite, we take pride in a long history of preserving the roads in many National Parks and Monuments across the nation, sustaining access to these treasures for future generations. In 1933, Granite won a contract to build the first roads into Yosemite National Park—Granite’s first collaboration with the Department of Transportation Federal Highways Association and the Department of the Interior National Parks Service. In the years since, Granite has paved hundreds of roads and parking lots in numerous National Parks and Monuments

Communities across the planet are experiencing more extreme weather events and changing climates. In California, recent fires have been devastating. A massive dry lightning storm in August of 2020 broke records, starting at least 650 wildfires in northern California that grew to affect over 2.5 million acres. As individuals and agencies repair the damage, Granite teams have helped with emergency response efforts, fire cleanup projects, and vital infrastructure repairs in communities across the state.

Granite had a unique opportunity to support the construction of a battery energy storage system in Moss Landing, California, contributing to the state’s clean energy transition. Granite worked in conjunction with Vistra, the project owner, and Fluence, the prime contractor, on integral parts of this project as the civil and structural contractor. Through advanced innovation, the power plant is creating positive change with sustainable solutions for the future.

The Derby Dam Fish Screen Project provides safe fish passage and facilitates recovery of Lahontan Cutthroat Trout (LCT) in Pyramid Lake and the Truckee River. The LCT are currently listed as threatened under the Endangered Species Act. This project protects LCT while providing irrigation water delivery to downstream water users, which will improve river connectivity, increase accessible fish habitat in the Truckee River, and support recreation opportunities in Nevada.
