Contractors have begun partially disassembling recent helipad construction on the White House South Lawn after President Trump ordered changes over dissatisfaction with the lawn’s slope.

Granite lettering spelling out the Seal of the President of the United States, installed on the pad just last week, was removed this week as part of the adjustments, according to people familiar with the project.

The helipad project stems from the need to accommodate the VH-92A Patriot, the newer presidential helicopter, whose test runs had scorched sections of the South Lawn under the previous landing setup. Construction on the new pad began after Trump’s backyard UFC fight held on the White House grounds in June.

Trump has said the project would cost $5 million or $6 million, with the expense fully covered by Lockheed Martin, the parent company of Sikorsky, which manufactures the VH-92A helicopters. It remains unclear how the latest round of changes, including the removal and expected reinstallation of the presidential seal lettering, will affect the final cost of the project.

The South Lawn has been a frequent site of construction and event staging during Trump’s second term, from the helipad work to the UFC fight staged there over the summer, drawing scrutiny from preservationists concerned about alterations to the historic grounds.

Presidents have periodically altered White House grounds for security, functional or aesthetic reasons, though the scope and visibility of the current helipad project has made it one of the more closely watched construction efforts on the property in recent years.

White House officials have not detailed a new timeline for completing the revised helipad, though the contractors’ work this week suggests the project remains active and is being adjusted based on Trump’s specifications for the lawn’s grading and finish.
