Robbins marked a major project milestone in Q4 2025 with the substantial completion of the factory acceptance test (FAT) for a refurbished Main Beam TBM<\/a> at its Solon, Ohio manufacturing facility. The veteran machine, rebuilt in partnership with contractor Kiewit, is set to excavate the 1.5 km (0.9 mi) long Ellicott City North Tunnel, a critical flood mitigation project in Howard County, Maryland, USA.<\/p>\n

The Robbins Main Beam TBM will bore through a mix of granitic rock beneath Ellicott City, minimizing surface disruption in the densely built, heritage-rich area.<\/p><\/div>\n

The 5.6 m (18.4 ft) diameter TBM, originally manufactured by Robbins in 1991, has a distinguished global track record. The machine has successfully excavated multiple tunnels totaling more than 18 km (11 mi) and is now entering its next chapter as part of Maryland\u2019s largest stormwater infrastructure project to date.
\n\u201cRobbins and Kiewit share a long-standing partnership focused on quality TBM rebuilds and performance,\u201d said Doug Harding, Robbins Vice President. \u201cWe are marking not only the acceptance of the machine, but also a continued commitment to delivering durable tunneling solutions that meet the evolving demands of major infrastructure projects.\u201d<\/p>\n

The Ellicott City North Tunnel is a centerpiece of Howard County\u2019s Ellicott City Safe and Sound plan. Designed to divert stormwater runoff away from the historic downtown area\u2014an area hit by multiple catastrophic floods in recent years\u2014the tunnel will convey up to 26,000 gallons (98,000 liters) of water per second during major storm events. The TBM will bore through a mix of granitic rock beneath Ellicott City, minimizing surface disruption in the densely built, heritage-rich area.
\n\u201cExcellent Engineers, Craft and Managers of Robbins and Kiewit have worked together at Robbins\u2019 plant in Solon on a daily basis over the last year to achieve this milestone of substantial completion of the FAT. Synergy efforts were required and well delivered to get the TBM to increased technical and safety standards,\u201d said Christof Metzger, Area Manager for Kiewit.<\/p>\n

The TBM is expected to begin tunneling in 2026 following TBM assembly and launch shaft construction in Maryland. Its performance will be supported by Robbins\u2019 field service team to ensure smooth operations throughout the project\u2019s duration.<\/p>\n","protected":false},"excerpt":{"rendered":"
