In the spring of 2021, JE Dunn awarded Bolander the site work construction for the Abbott Northwestern Central Utility project. Once awarded, we worked closely with the client on the high-level planning required to execute this complicated project. Bolander’s work consists of Building Demolition, Earth Retention, Excavation & Site Utilities.
Located on the corner of Chicago Avenue and East 26th Street, the new Central Utility Plant will replace the hospital’s outdated energy and steam-producing equipment with more reliable and energy-efficient technology. The hospital currently relies on steam and energy equipment dating back to 1956.
The project started with the demolition of the existing Harriet Walker and the Education buildings. Standing 6-Stories tall, the Harriet Walker building was a perfect opportunity to utilize the Liebherr R960 High-Reach Demolition Excavator. This machine has multiple configurations and the ability to reach 108’!
The Earth Retention portion of our work includes drill & set H-Pile and lagging, tie-backs, internal bracing, as well as soil solidification. Given the proximity to existing structures that are to remain intact as well as active medical facilities, vibration was a significant concern. Bolander worked with our engineering consultant to develop a plan to alleviate these concerns.
This project shows our ability to coordinate and collaborate with the general contractor as well as the other project partners and stakeholders.
