Mammoth red oak tree to be transplanted on the George W. Bush Presidential Center project site

Thursday, June 9th, 2011

DALLAS – A mammoth red oak tree is scheduled for relocation to the George W. Bush Presidential Center project site on the morning of Friday, June 10. It will be transplanted from its current location on a part of the Southern Methodist University (SMU) campus property that is scheduled for demolition. The 45-foot-high tree is the largest of the 40 trees transplanted on the project site, either from other areas of SMU property or from other locations within the construction site.

“They don’t make a tree spade large enough for a tree with a 25-foot root ball like this one, so our tree-moving team is using a gantry lift system,” said Manhattan Construction Project Executive Mark Penny. “This gantry equipment has moved the largest trees ever relocated in the world, and it is being used here in Dallas for the first time.”

“We have been preparing this 50-year-old red oak for transplant for about three weeks,” said Penny. He and his team will be following a series of best practices to acclimate a tree of this size to ensure its survival during transplant.

“Our subcontractor, Environmental Design has pruned the roots, encapsulated the root ball and inserted a steel lifting platform beneath the root ball,” Penny said of the process. “They used a four-point gantry hydraulic lift to raise the 245,000-pound tree onto a specialized trailer for its trip across campus.”

On Friday, the tree will travel 2,500 feet to its final location on the north side of the George W. Bush Presidential Center project site, said Penny. On Saturday the tree will be lowered into its new place.
