How a 900-pound steel beam is installed in a restricted residential space

This episode demonstrates the logistical challenges of home renovation, focusing on the precision required to install a massive structural support beam in a tight site. It provides a practical look at how modern construction techniques and safety protocols integrate with historic home preservation.

The episode centers on the installation of a 17-foot-long steel beam weighing 900 pounds, designed to support a 16-foot opening in a rear foundation wall. Due to limited site access, the crew utilizes a crane to maneuver the beam over the house. Beyond structural work, the team explores the use of insulated concrete forms for both foundations and above-grade walls.

The project also addresses the transition from a 1940 kitchen layout to a modern design, while highlighting the importance of adhering to lead safety laws during interior demolition. The episode serves as a case study in balancing historical integrity with modern building standards, emphasizing the necessity of proper testing and professional protocol when renovating older properties.
