We’ve got a date. Schedule your party.

Martin Tower is coming down Sunday, May 19, likely in the early morning, HRP Managment LLC representative Duane Wagner confirmed Thursday morning.

All details surrounding the planned implosion of the former Bethlehem Steel headquarters building at the corner of Eighth and Eaton avenues will come from Bethlehem’s emergency management department, Wagner said.

No firm time is set.

“It’ll be done in the daylight hours, but in the morning when it is least disruptive to anybody,” said Robert Novatnack, Bethlehem emergency management coordinator.

Bethlehem business administrator Eric Evans said the city is in the process of developing a Martin Tower demolition website where the public can find everything they want to know about one of the most-anticipated local events of 2019.

“The property owners, city of Bethlehem and demolition experts, are working together on defining safe areas for viewing as well as restricted areas where no one shall be permitted," according to a news release from the city. "An area map will be provided at a later date and will include all street closures and restricted areas.”

Novatnack expects the map to be available in about three weeks and it will let people know where the safe zones to watch the demolition are located. And it will detail the lines where folks looking for a front-row seat for the implosion should not cross.

The property’s swaths of open space and woods make demolition easier and safer in some ways, but also present challenges for public safety officials who want to ensure no one in hiding in the woods in a danger zone.

Mayor Bob Donchez has tapped Novatnack as the point-person to coordinate the demo with Martin Tower owners Norton Herrick and Lewis Ronca as well as state Department of Environmental Protection officials.

“All necessary provisions to ensure the safety, health and welfare of the public are being taken for this large undertaking,” the city said in its news release.

Every detail will be vetted -- from the underground utilities to where things can land and what roads should be shut down -- and a master plan for the implosion created. There will be an emergency command post established during the tear down.

Novatnack has said he anticipates creating three zones in the neighborhood surrounding the tower. The hot zone is where the demolition is happening; the warm zone is where only the demolition crew and public safety folks will be permitted and the cold zone will be where folks can watch the tower come down and take pictures.

Residents and businesses will be alerted of road closures and if any properties -- homes or businesses -- should be empty during the actual demolition. It is likely that Eighth Avenue and Route 378 will be completely shut down, but Novatnack does not know where the closures will begin.

During a Bethlehem City Council tour of the property Wednesday evening, it was explained that the tower is expected to fall towards the southeast edge of the roughly 53-acre property, almost on a diagonal.

Each of the supporting columns will essentially be wrapped in shaped charges of explosives, angled so they are meant to cut straight through and take down the building. There will be hundreds placed around the building going off at synchronized times.

Under a controversial 2015 rezoning that cleared the building for demolition, Ronca and Herrick are required to submit a master plan detailing everything they want to build. The Bethlehem Planning Commission is slated to review the master plan April 11.

The developers plan to invest $200 million in reimagining the property into a work-live redevelopment, featuring 528 upscale garden-style apartments along the eastern edge of the property, a 132-room hotel and a gas station and convenience store. It also includes two retail buildings totaling 33,100 square feet, a 5,080-square-foot restaurant and three medical office buildings totaling 124,854 square feet.

A trail surrounding the site is designed to promote walkability and links to city and county parks, plus walking trails along the nearby Monocacy Creek.

Martin Tower opened as world headquarters of the now-defunct Bethlehem Steel in 1972 and sits on the National Register of Historic Places. Its cruciform design, seen from above, maximized the number of corner of offices for Steel executives, offering expansive views of the Lehigh Valley. It has been vacant since 2007.

That same design made its reuse financially unfeasible, leaving the developers to decide to tear down the building and start from scratch.

The tower’s namesake is Bethlehem Steel’s Chairman Edmund F. Martin and it stands eight feet above Allentown’s PP&L building, which will soon be the Valley’s tallest building.
