Project Overview
Sundt executed a largescale project that allowed our client to comply with strict ambient sulfur dioxide (SO2) levels, helping them maintain EPA regulatory compliance while increasing pollution control. In the process, Sundt also expanded the client’s operations. As the mining company’s first major construction manager at risk contract, the project was delivered successfully resulting in significant cost and time savings for the owner.
Sundt’s scope included installation of a complex scrubber system to capture SO2 off-gas in an active copper smelting refinery. An upgraded bag house and a caustic solution system were added to meet EPA standards. Sundt also performed demolition of the existing 100-year-old smelter legacy structures, as well as earthwork, caissons, shoring and rebar for caissons, structural steel, mechanical equipment, piping and major electrical upgrades. The work included multiple shutdowns and tie-ins to the existing operational facility.
Before work began, the project underwent an extensive preconstruction period, which involved international travel to meet and coordinate with the engineer of record. To achieve the EPA-mandated compliance date for project completion, GMP development used a phased approach. The schedule was managed by moving critical work forward to synchronize with the two shutdown periods. Ultimately, our diligent planning and close communication with operations personnel led to a safe and timely completion.
