Flint Creek Power Plant Activated Carbon Injection and Dry Flue Gas Desulphurization Civil Package and Welsh Power Plant Civil Package
In order to meet strict new regulations from the U.S. Environmental Protection Agency, the Flint Creek Power Plant needed a handful of upgrades. Brasfield & Gorrie provided the site development, civil and structural package, and underground mechanical work for the activated carbon injections as well as dry flue gas desulphurization.
Fukushima Warehouse Projects
After an earthquake and a tidal wave heavily damaged Japanese nuclear reactors in 2011, the U.S. Nuclear Regulatory Commission required significant enhancements to American commercial nuclear power plants. Brasfield & Gorrie was tasked with a design-build project that included three separate single-story, pre-engineered metal warehouses in the Carolinas that would…
Gantt Dam Gate Refurbishment
The hydroelectric plant at Gantt Dam has provided reliable and economical energy for many decades, and upgrades eventually became inevitable. Our team improved the facility’s four tainter type spillway gates by removing the timber facing and replacing it with steel plates as well as installing five track racks provided by…
Goat Rock Dam Turbine Installation
When the Goat Rock Dam acquired two new horizontal bulb-type turbines, generators, and other associated equipment, they needed extensive powerhouse modifications to complete the upgrade. Over the course of eight months, Brasfield & Gorrie oversaw extensive demolition and modifications of the existing concrete powerhouse structure as well as modifications of…
Kemper County IGCC Power Plant Concrete Foundation and Underground Package
To call this facility “cutting edge” would be an understatement. This new greenfield integrated gasification combined cycle power plant has drawn interest from companies around the world looking for forward-thinking approaches to coal-powered energy, which has led to countless site visits for members of the United Nations and other foreign…
Lake Martin Dam Arch Replacement
Lake Martin was the largest manmade reservoir in the world when it was created in 1926—when means the Lake Martin Dam needs consistent maintenance. Brasfield & Gorrie was commissioned to demolish and replace 20 bays of concrete arches on the spillway, which included three arches per bay for a total…
Logan Martin Dam Forebay Oxygen Diffuser System
To meet the Federal Energy Regulatory Commission’s required standards for hydroelectric generation, the Logan Martin Dam needed an improved liquid oxygen diffuser system. As part of the Coosa River Dams Aeration project, the secondary aeration system was installed on the forebay side of the dam, and the diffuser system includes…
Martin Dam Powerhouse Crane Structure Rehabilitation
When the 200-ton crane at Martin Dam reached a point that it needed to be replaced, there was an issue: the existing crane structure was insufficient to support the new crane loads. Brasfield & Gorrie was brought in to rehabilitate the structure to install the new crane. The project consisted…
North Carolina Hydropower Station Spillway Modification
The hydroelectric power station at Blewett Falls Lake needed significant upgrades, including modifications to the spillway crest, an addition of post-tensioned rock anchors, and replacement of spillway flashboards with pneumatically operated gates. Because this project took place in and around the Pee Dee River, most of the work was performed…
North Carolina Hydropower Station Upstream Fish Passage
Because the Pee Dee River is a prominent habitat for migratory fish species like the American shad, it was important that the Blewett Falls hydroelectric power station allow these populations to thrive. Brasfield & Gorrie was selected to build a fish passage that would enable these species to swim upstream…
