Preserving History Through Precision
September 18, 2023
In the heart of Boston’s historic Back Bay, a unique project recently unfolded that required both precision engineering and a deep understanding of historical preservation. The task at hand was the partial demolition of a condemned church, dating back to 1896, nestled at the intersection of Stuart and Arlington streets. The project was undertaken by NDA member JDC Demolition, a company with a proven track record in handling similar ventures.
Selection and Rationale
JDC Demolition was chosen for this endeavor due to its prior experience with projects of this nature and a history of successful outcomes. The developer, Kems Corp, recognized the importance of expertise in the delicate process of partial demolition. The church’s location within Boston’s Back Bay, known for its architectural significance, demanded an approach that balanced the need for structural change with the preservation of historical elements.
Project Timeline and Equipment
The project kicked off in mid-May 2023 and concluded toward the end of July, showcasing the efficiency of the selected team. The equipment utilized included a Volvo 480 HR and 135’/150’ boom lifts. These tools were crucial in executing the multifaceted strategy devised for the project.
Demolition Strategy and Uniqueness
JDC Demolition’s scope encompassed a series of intricate steps, demonstrating the complexity of the task at hand. The strategy involved engineering a partial structural dismantling plan, focusing on preserving the exterior perimeter walls that were to remain after demolition. The coordination with a bracing design was instrumental in ensuring the stability of these walls.
The unique challenge arose from the requirement to retain the outer four walls of the church. These walls, exposed to years of weather and environmental elements, necessitated a $1.5 million shoring system for support. JDC Demolition meticulously planned each phase, including the removal of the upper roof structure, demising arched masonry wall, and lower roof and support structures. This intricate sequence allowed the team to safeguard the historical significance of the structure while carrying out essential demolition.
Execution and Challenges
The project was not without its challenges. One of the key hurdles was coordinating with neighboring properties, instilling confidence that the process was structurally sound and ensuring the safety of crew members. Tight site logistics and working at heights exceeding 60 feet added further complexity. Effective communication between personnel working at different levels was paramount to maintaining a safe and efficient work environment.
Environmental Responsibility and Salvage
While the focus was on dismantling, the project also exhibited a commitment to environmental responsibility. Approximately 50 tons of steel, cast iron and southern yellow pine from the roof and floor framing were carefully salvaged and recycled, minimizing waste and maximizing sustainability.
A Successful Endeavor
In the eyes of JDC Demolition, success was achieved through meticulous planning, strategic execution and effective communication. The project was a testament to the company’s ability to blend expertise in demolition with a profound respect for historical preservation. The team’s dedication to understanding the intricacies of the church’s structure and crafting a unique demolition strategy ensured that the project achieved its objectives without compromising the historical value of the remaining exterior walls.
