Project Profile: Hoffman Mill Fuel Site
Fort Collins, Colorado
The City tasked CGRS with moving the three tanks and their dispensers from sites in three different parts of town to the Hoffman Mill site. The team completed this – including decommissioning all three tanks – all in one day in mid-February.
“The biggest hurdle we faced with accomplishing this was the coordination,” said Drew Higgins, CGRS Construction Services Project Manager who headed up the job. “We needed to have a City representative, State inspectors, the Fire Marshall, a crane and our crew synced to caravan to each site in an efficient manner. We were able to do this very efficiently and were done with all three sites by lunchtime.”
CGRS’s responsibilities included installing all electrical, grading, drainage structures, tank painting, piping and concrete work before moving tanks, and doing all of the necessary installations.
Moving each tank required draining, evacuating and disposing of all lines, and removing and disposing of all wiring and conduit. Prepping the new location and installing the tanks included the site drainage plan, dirt work, concrete, utilities, new fencing, new landscape, and new fuel system that included new piping with the previously used tanks and dispensers, which went in last.
Through its existing contract with the City, CGRS Environmental Services provided tank closure duties, which consisted primarily of taking photos and preparing reports.
Higgins said the biggest issue CGRS has faced while completing the project is finding a three-phase (high voltage) power line on the site that was not on the City’s original drawings for the project. The discovery caused significant interference with the design of the project as the power line’s elevation was higher than the designed stormwater flow line. City representatives, the architect, the engineer, the City’s Light and Power division, and CGRS team members took several weeks to come up with a plan to address the issue.
Meanwhile, CGRS moved forward with the fueling side of the project, with which the power line didn’t interfere. While the delay did cost four to five weeks on the civil side of the project, the team is working to make it up in less time.
Higgins said CGRS has been able to continue with the project despite the restrictions resulting from the spread of COVID-19, and all crew members have remained healthy.
“We are diligently following the Centers for Disease Control (CDC) recommendations as well as the instructions form the governor,” he said. “The remaining work to be completed on-site does not require any of the workers to be within 6 feet of each other. CGRS has been diligent in making sure crews are feeling well and providing cleaning supplies and hand sanitizer.”
The fact that this project is located close to CGRS has definitely been a benefit.
“It’s not every day we get to work in Fort Collins, so when a project comes up like this, in our backyard, it really eliminates many of the hurdles we can face during out-of-town projects,” Higgins said. “This project was a great chance for our Civil/Water/Wastewater and the Refined Fuel teams to come together and provide our client with an end product worth bragging about.”
The Hoffman Mill Fuel Site should be operational by the end of April.
