Crane Safety at the Sacred Heart School Demolition

Empire Services • September 14, 2021


For 115 years, the Sacred Heart School has been a landmark in Allentown, PA. Unfortunately, a devastating fire on June 10, 2020, destroyed it. The multi-alarm fire caused extensive damage to the roof and the supporting structure for the roof. Smoke and water damage was throughout the structure as well. Once the damage was assessed, the Diocese of Allentown concluded that the building would be demolished and not rebuilt. Empire Services was contracted by Stellar Construction to demolish the three-story building. The biggest part of the strategy involved the use of a crane, which involved two weeks of preparation leading up to the crane being on site. We used a 110-ton hydraulic crane subcontracted from Dickinson crane to remove the steel roof trusses. 

Crane Safety Protocols

The use of a crane requires crane safety protocols to be in place. At Empire Services, safety is our priority, not only for our employees, but also for our subcontractors, customers, and the community. For this project, a lift plan was done and vetted by I.B. Dickinson & Sons, Inc. It consisted of dry runs prior to actual lifts performed, site layout and pre-planning, on-site meetings to review the lift plan and crane set area, radio communication, hand signals, spotters on the ground and in a high reach. We also utilized guide ropes/tag lines with ground personnel guiding the trusses to the staging area on the ground.

The Demolition Process

With crane safety implemented, the demolition process could begin. The equipment chosen for the project also included a John Deere 450 excavator with long boom and rotating grapple, track loader, lull, and a 120-foot-high reach. The strategy of this demolition is to remove from highest to lowest, and finishing with the cleanup, stoning the top and filling the basement with clean fill. The process was started by removing the interior timber walls on the third floor. The walking bridge has been separated on the third floor from the adjacent school building, sealing off the opening. The piping was removed from the three-story structure. The removal of the fire-damaged roofing materials and timbers attached to the steel trusses came next. A few of the key cross timbers remain to provide lateral support for the 5,500-pound steel trusses until it is time to lift them off with the crane. 


To remove the trusses, the front façade of the building was removed by hand to matching elevations of the adjacent exterior walls. This provided clearance and a clear line of sight for the man lift and the crane to reach the steel trusses for safe removal. After the front façade was demolished by hand, bringing it down the same plane as the exterior walls, it provided the proper clearance for the 120-foot-high reach to rig and visually spot for the crane removal of the trusses. The high reach was used to keep the spotters out of the structure and in line of sight of the crane operator. The chimneys on the north and south walls of the structure will also be demolished by hand down to match existing exterior walls on either side of the building. 


The main challenge of the project is the limited staging area. The building is located on a busy, two-lane street and is very close to adjacent buildings, overhead power and communications lines and a guide wire for another utility pole. However, our crew has the experience to expertly work and maneuver equipment in tight spaces. Traffic control has been implemented to ensure vehicles can safely pass through the demolition area. Demolition currently continues to bring the building down to the ground while removing construction debris. The project is estimated to be completed next month.

On Saturday, August 15th, Empire Group employees and their families gathered at Knoebels Amusement Resort in Elysburg, PA, for a day filled with good food, laughter, classic rides, and quality time together. With nearly 100 employees and family members in attendance, this year’s Empire Group Family Fun Day was a wonderful opportunity to step away from the daily routine and enjoy being together. A Picnic Lunch to Kick Off the Day Before heading into the park, everyone gathered for a delicious picnic lunch featuring plenty of summertime favorites. A big thank you goes to Russ and Kristi Mountjoy for preparing the meal, providing the food, and manning the grill. With full plates and plenty of good conversation, it was the perfect way to start the day. Then, it was time to head into the park for roller coasters, train rides, games, and attractions. Making Memories, One Ride at a Time Throughout the day, everyone enjoyed all the park had to offer. Some took on the thrills of the rides, while others enjoyed a more leisurely day exploring the park. Rick and Melissa Dom took a relaxing train ride with their Yorkie-Poo, Ahsoka Tano. Meanwhile, Ellyn Harkin's niece and nephew may have been too small to ride the famous Phoenix wooden coaster, but that didn't stop them from getting in on the fun. They posed for a memorable picture in one of the coaster's cars instead! This year’s location was especially fitting. Knoebels is celebrating its 100th anniversary. The park traces its roots to 1926, when Henry Knoebel opened a swimming pool, restaurant, and carousel at his farm near Elysburg. Over the past century, Knoebels has grown into a beloved Pennsylvania destination with more than 100 rides and attractions, while maintaining the family-friendly atmosphere that has been part of its story from the beginning. Celebrating Empire Group's Family Fun Day at a Pennsylvania attraction with a century of family memories behind it was a fitting way to celebrate our own company family, with 70 years of memories and our 10 th anniversary at Knoebels. A Special Thank You We extend our heartfelt thanks to Todd & Karen O’Neill and Harry & Cathy O’Neill for making this special day possible. Their generosity and thoughtfulness allowed employees and their families to come together and enjoy one another’s company outside of the workplace. More Than a Day at the Park This event brought the entire Empire Group together, creating fun memories while enjoying a wonderful lunch, friendship, and a variety of classic rides. It’s just one of the many events the company hosts to celebrate employees and build connections. These moments of joy and community are what make Empire Group feel like a family. We can’t wait until next year’s Family Fun Day!

Demolition is about more than tearing something down. It is often the first step toward giving an existing property a new purpose. An outdated building may need to be removed for new construction, an aging structure may need to be carefully dismantled while preserving portions of the property, or an existing space may need to be stripped down before it can be renovated. In urban environments, such as Reading, PA, these projects can present unique challenges. Buildings being demolished are sometimes located close to homes, businesses, and other structures, which can make job site space limited, reroute pedestrians and vehicles, and necessitate protection of utilities and other infrastructure. Completing this type of demolition requires careful planning, specialized equipment, and an experienced workforce that understands how to work safely in limited spaces. Empire Services brings that experience and precision to challenging demolition projects throughout Reading and the tri-state area.

When people think about roads and transportation infrastructure, bridges and highways often come to mind. Yet some of the most important infrastructure is hidden beneath our feet. Storm sewer culverts carry water under roads, railroads, driveways, and embankments, preventing flooding, protecting roadways, and preserving the surrounding environment. Although they are rarely noticed, culverts play a vital role in keeping communities safe. When these underground structures begin to fail, the consequences can include flooding, roadway damage, sinkholes, traffic disruptions, and costly emergency repairs. At Empire Services, preserving infrastructure means staying ahead of these problems. The company's experienced crews recently completed a storm sewer culvert replacement project for Earl Township, restoring an aging drainage system that will continue protecting the roadway and surrounding properties for years to come.

If you ever played the game Operation , you probably remember the pressure. One wrong move with the tweezers and suddenly the buzzer sounded, Cavity Sam’s nose lit up, and your turn was over. Winning the game required patience, coordination, and a steady hand. That same level of precision is happening right now on one of Empire Services’ industrial demolition projects. Empire Services has been contracted by Warfel Construction Company to remove an old roof and support structure at a processing plant to prepare the space for brand new roof construction. While roof demolition may sound straightforward, this project is anything but ordinary. Directly beneath the roof, located in the middle of the active processing plant, are vital active utility lines that can’t be disrupted, creating a high-stakes environment where every cut matters. Just like the game Operation , the Empire Services team must work carefully, methodically, and strategically to avoid “touching the sides."

When businesses grow, their spaces need to evolve with them. Whether it’s reconfiguring an office layout or repurposing an older industrial property, renovation is often the key to unlocking a company’s full potential. For many organizations, purchasing an existing structure offers the space they need—but it also presents the challenge of transforming it into something functional, safe, and future-ready. That was the case for Empire Services with the pit project at a former manufacturing facility.
