East River Contracting LLC — commercial framing & concrete in Watertown, SD
East River Contracting launched in October 2019 with a clear specialty: commercial framing and cast-in-place concrete work across Watertown and the wider northeast South Dakota market. The company has grown steadily since then, with a workforce of 100 to 500 employees and a typical project range of $100,000 to $1,000,000. That puts it well above the usual small-town contractor in both capacity and scope.
The average contract size tells you something useful about who calls them: developers, municipal clients, and commercial property owners who need a firm that can staff a job properly and keep it on schedule. One reviewer put it simply: “Kudos to your framing crew. The jobsite is clean, they are being very productive, and they are safety conscious.” That kind of feedback shows up in a 4.1-star rating across review platforms, and it points to a crew that takes the basics seriously.
East River is a member of the Watertown Area Home Builders Association, which connects them to the broader network of builders, suppliers, and trade professionals operating across Clark, Codington, and surrounding counties.
Services
Cast-in-place concrete is the foundation of their work, covering poured slabs, structural foundations, and commercial flatwork. Their framing division handles both conventional wood framing on office and retail structures, and post-frame construction for agricultural buildings, large garages, and rural storage.
Post-frame is worth a specific mention if you’re in the region. It brings the cost-per-square-foot down considerably compared to conventional stick framing, and East River’s crew capacity means they can staff a post-frame agricultural job without the delays you’d expect from a smaller firm pulling double duty. That flexibility across commercial and farm work is what sets them apart from more narrowly focused concrete-only shops in Watertown.
Service area
East River operates throughout Watertown and northeast South Dakota. Their Procore network profile shows coverage across the region, and their workforce supports larger projects that smaller contractors simply can’t staff from a standing start.
