According to Sage, one of the most challenging aspects of the project was retrofitting the new technology and support systems into the existing plant layout. “The team had to work closely together to strategically place the equipment in areas where it would have minimal impact on the site,” he said. “From a design perspective, we found efficiencies by using a 3D model to coordinate key items between the two parties.”
In one case, Sage explained that onsite congestion made it difficult to locate air compressors and water recirculation pumps, which normally would be housed in an auxiliary building. Without the space to build one, the team determined it could place the compressors and pumps within the absorber enclosure, under the conical-shaped lower portion that collects solids. This excess space under the absorber vessel had historically been left unused.
Solutions like this one also helped the team keep costs down—another challenge posed by the client. “It was important to them that we deliver the project economically, as well as efficiently,” said Sage. Applying their ingenuity throughout the project, the team delivered their scope of work under the contracted price, resulting in shared savings with the client.
Now installed, the new FGD system has brought the plant into compliance and underscored Colorado Springs Utilities’ commitment to providing power to its customers responsibly. “At the end of the day,” said Sage, “the client is happy, and the project was on time and under budget. That’s a testament to the careful planning and management of the project team.”
