Super Excavators

What Super Excavators does

Super Excavators, Inc. is a privately held, family-owned heavy civil construction contractor founded in 1950 in Milwaukee, Wisconsin and now headquartered in Menomonee Falls, WI. The company specializes in complex underground infrastructure for municipal and government clients, with core capabilities spanning large-diameter tunneling (4-foot to 23-foot), microtunneling (24-inch to 85-inch) in conditions ranging from wet sands and silts to cobbles/boulders and solid bedrock, deep foundations (drilled shafts, driven piles, micropiles, earth retention), open-cut utilities, GPS-enabled grading, slip lining, and pipe bursting. Operations are executed using an owned fleet of specialized equipment — Tunnel Boring Machines (TBM), Microtunnel Boring Machines (MTBM), and Earth Pressure Balance (EPB) TBMs — together with an affiliate network that includes Super Western Inc. (civil construction since 1998), CRS Tunneling, SX Blasting, and SX Foundations.

The company's revenue model is project-based heavy civil construction services, generated exclusively through competitive bidding on municipal and government infrastructure RFPs across the United States and Canada. Contract values for individual projects range from approximately $14.8M to $57.5M (e.g., $57.5M NEORSD Dugway West, $44.9M SFPUC Sunnydale, $27M Blacksnake Creek, $21.5M City of Omaha), with no recurring SaaS, licensing, or product revenue streams. Its customer base consists entirely of public-sector entities — cities, regional sewer districts, transportation departments, and water/wastewater utilities — making it dependent on the public infrastructure spending cycle. Notable technical achievements include the first curved 72-inch MTBM microtunnel in the Midwest, a 2,300 LF record MTBM drive in 2020, and roughly 12,000 LF of microtunneling completed in Providence, RI within 19 months.

Super Excavators is currently led by President Peter Schraufnagel, representing the third generation of the founding family. The go-to-market motion is enterprise field sales into municipal procurement, supported by industry-publication PR, project awards (CATT, Trenchless Technology, APWA, ASCE, DBIA), and case-study content on its website. The business has no external institutional investors, no public listings, and no disclosed funding events, and operates as a union employer signatory to multiple unions nationwide to secure trained craft labor for projects across geographies.

Products and services

• Tunneling Services Large-diameter tunnel construction services for 4-foot to 23-foot diameter tunnels, including tunnel lining applications such as jacking pipe, pre-cast segmental lining, ribs and lagging with reinforced concrete pipe lining grouted in place, primarily for municipal sewer, water, and stormwater infrastructure.
• Microtunneling Services Trenchless microtunneling services producing tunnels from 24 inches to 85 inches in diameter across varying ground conditions, including wet sands, silts, cobbles, boulders, and solid bedrock, for municipal utility clients.
• Foundations Deep foundation and earth retention systems including drilled shafts, driven piles, micropiles, earth retention systems, specialty drilling and excavation, grouting, and slope stabilization for civil and infrastructure projects.
• Open Cut Utilities Open cut trenching of sanitary sewer, storm sewer, and water mains to cost-effectively replace older and smaller pipes with larger piping and extend the service life of aged utility systems.
• Grading Services Site preparation grading using GPS technology for accuracy and efficiency, including installation of new roadways and parking lots, river re-alignment, and shoreline restoration.
• Slip Lining Trenchless structural rehabilitation of existing pipe that minimally impacts traffic and reduces surface disruption, offering a more cost-effective and reliable alternative to open cut or cured-in-place solutions.
• Pipe Bursting Trenchless pipeline rehabilitation that pulls a new pipe into an existing pipe, statically or pneumatically, lowering surface restoration costs, reducing surface disruptions, and minimizing traffic disruption.
