Fenway Foundation Feat by Ultra‑Lum
April 30, 2026
In the heart of Boston, just steps from the iconic Fenway Park and the well‑known Sal's Pizza, Ultra‑Lum was tasked with installing the foundation for a new high‑visibility billboard structure. The project required precision, power, and absolute reliability; especially given the tight urban footprint, heavy pedestrian traffic, and the dense network of utilities common to historic Boston neighborhoods.
Ultra‑Lum is the preferred billboard installer in the Northeast with decades of experience performing foundation work in challenging environments. Their experience working in constrained urban spaces made them the ideal contractor for a project requiring both technical expertise and logistical finesse.
To drive the oversized caissons, Ultra‑Lum bought and used a brand‑new ICE® 70 Vibratory Hammer; the first unit ever manufactured. This hammer represents the next generation of high‑energy vibratory technology. With an eccentric moment of up to 7000 in/lbs and an operating frequency engineered for both power and control, the ICE® 70 delivers the driving energy needed for large‑diameter caissons while maintaining stability in sensitive urban environments. Its hydraulic system, designed for high flow and high pressure, ensures consistent performance even under demanding load conditions. Supporting the hammer was the durable and flexible Hydrauli‑Flex™ hose, engineered to withstand demanding jobsite conditions and ensure consistent power delivery throughout the installation.
To complete this job, Ultra‑Lum first installed an 84" (in) caisson and then excavated it to a depth of 16' (ft). They followed this by then installing a second caisson, measuring 54" (in), that extended 60' (ft) deep. Next, the space between the two caissons was filled with concrete to provide the additional ballast required for long‑term stability, as a 48" (in) diameter x 60' (ft) long steel pipe with a 1½" (in) wall thickness was used to connect the foundation to the digital screen structure. That 60' (ft) lateral support arm extended over Sal's Pizza. Together, these elements form a critical foundation designed to anchor the billboard securely even during the toughest Nor'easters. The success of this installation was essential not only for structural integrity but also for ensuring long‑term safety in one of the city's busiest commercial corridors.
International Construction Equipment (ICE®), which proudly manufactures all of its vibratory hammers in the United States, extends its appreciation to Ultra‑Lum for trusting the first‑ever ICE® 70 on such a prominent project. The local community and nearby businesses have also expressed their thanks for the professionalism and efficiency shown throughout the installation, ensuring the work was completed safely and with minimal disruption. And as the new billboard rises over Sal's, it's safe to say this foundation is as solid as the Fenway slice is famous!
