President Trump has ordered contractors to redo the construction of the White House helipad, expressing frustration with its appearance after weeks of work, according to reports from The Hill and the Washington Post.

The helipad project, which began in June and was a priority for Trump, has faced criticism from the president who desires a landing pad level with the horizon. Achieving this would require dismantling current work and potentially leveling the sloped South Lawn. While Federal Aviation Administration guidelines do not mandate perfectly horizontal helipads, they recommend flat surfaces for water runoff.

White House spokesperson Davis Ingle told The Hill that the helipad was “desperately” needed to allow the president to land safely and to protect the South Lawn grass from the exhaust fumes of Marine One, the presidential helicopter. An administration official described the improvements as part of an ongoing effort to best match the historic building's needs.

Sikorsky Aircraft, a Lockheed Martin subsidiary that manufactures the VH-92A Patriot helicopters used as Marine One, is covering $6 million of the helipad costs. Trump stated last month that upon learning Sikorsky was paying the full cost, he encouraged making the helipad aesthetically pleasing.

This helipad renovation is among several changes Trump has made to the White House during his second term, including adding gold accents along the West Wing pathway, paving over the Rose Garden, and installing portraits of former presidents with partisan descriptions, which he calls the “Presidential Walk of Fame.”
