Dearborn Cools Off Lancaster Residents
During the warm months in Chicago, the Lancaster Condominiums faced a critical need for an HVAC system update. The project involved replacing two 18,000-lb rooftop HVAC units, complicated by the only viable crane setup area being atop a 4-story parking garage. This demanding scenario required meticulous engineering to ensure the parking structure could support the significant weight of the crane and the HVAC units without safety compromises.
Dearborn Companies was tasked with a comprehensive analysis to determine the most feasible crane placement. The chosen location, optimal for reach and accessibility, presented a challenge due to its elevated position. The solution entailed advanced engineering calculations and strategic placement of shoring to reinforce the structure.
To meet the intricate demands of this HVAC replacement, Dearborn Companies worked in close collaboration with Magellan Development Group, Midwest Mechanical and Stevenson Crane. This partnership was crucial in planning and executing the safe, efficient installation of the new units, ensuring every detail of the crane operation was meticulously managed.

- Chose ideal crane placement of a 550-ton crane
- 4-story parking garage had to be properly shored
- Used laser scanning for in-depth site analysis
Selecting the appropriate crane was critical. Led by Dearborn’s engineering experts, the team chose a Liebherr LTM 1500 crane, with the necessary capacity for the heavy loads and suitability for operation on the reinforced structure. This decision was vital to maintaining the integrity of the garage and meeting the logistical needs of the project. The project’s success hinged on the thorough initial planning and preparation. Dearborn conducted extensive structural analyses to design a support system that could manage the weight of the crane and the HVAC units. Shoring solutions were implemented to distribute the load evenly across the garage structure, averting potential failures.
The crane operation was executed flawlessly, with the new HVAC units hoisted and installed without incident. The preparation and strategic shoring ensured there were no integrity issues with the parking garage, and the project not only met but exceeded safety standards. This swift, secure installation ensured a quick return to comfort for the residents of Lancaster Condominiums.
The Lancaster Condominiums project underscores Dearborn Companies’ commitment to solving complex engineering challenges with meticulous planning and strategic execution. This endeavor stands as a testament to the skill and precision that Dearborn brings to each project, ensuring client satisfaction even under the most challenging conditions.
