Progress Continues

August 2017 Update

The concrete work at the National Law Enforcement Museum at the Motorola Solutions Foundation Building has ended, marking a major completion milestone. The next big thing that you will see unfolding on the webcam over the next few months will be the construction of the two large glass pavilions. These pavilions will serve as entry and exit points to the underground structure. This will also mean our construction tower crane will soon be leaving the site. After the tower crane is gone, most construction material will find its way into the building via the freight elevator on the east pavilion. This is how the exhibits will enter the building after the glass pavilions are finished. The glass pavilion work will be completed in December and the building will have its air conditioning and heating system working at that time.

Construction Trivia

  • 55,000 cubic yards of dirt were removed from the site to make room for the Museum. Some of the dirt went to the new D.C. United Soccer Stadium.

  • There is enough rebar in the construction project to go around the Washington, DC, Beltway almost three times.

  • 188 blue whales or 3,667 elephants could fit into the excavated area for the Museum.
There has been a lot of progress at the Museum construction site in 2017. Concrete work is complete on the basement and main exhibition floor. The basement, the deepest area of the site, reaches approximately 65 ft below ground. This area will contain the Museum’s air conditioning and heating equipment. Currently, concrete work is focused on the visitor services level which includes the Museum’s café, office space, ticketing, and gift shop. On the exhibit floor, Clark Construction is finishing up the concrete support columns. In early summer 2017, the escalators will be installed in one piece using the 160-foot-tall tower crane. The only way to install the escalators is with the roof still open. Once the roof is closed, the only way to get big items in the building will be through the freight elevator. The elevator shaft is currently being installed on the East side of the building.

Concrete work has begun at the Museum construction site. Currently, the foundation level has been poured, and contractors are creating the retaining walls of the Museum, followed by the structural columns. They will then pour the floor separating the exhibit gallery from the visitor level. After this segment of work is completed, webcam viewers will enjoy watching as the escalators are lowered into place using the tower crane. After the large pieces are inside the building, work will begin on completing the exterior. By the end of June, the building will be back up to ground level, and the crane will be dismantled. While work has been going on at the site in Washington, DC, progress has also been made in Germany where the signature glass pavilions are being assembled. The pavilions are roughly assembled, taken apart, and then painted at which point they are shipped to the construction site in Washington, DC where installation will begin this summer.

November 2016 Update (click to read)
There was a lot of progress at the Museum construction site in November. The deepest area of the site, in the East corner, reaches approximately 65 ft. below ground and is completely excavated. This area is the basement level and it will contain the Museum’s air conditioning and heating equipment. Along the walls of the excavation there are hundreds of five inch thick boards. These boards keep the soil from falling into the construction pit. In many of these boards, there are, what looks like big pipes or wires sticking out, called tiebacks. They secure the wood boards to the dirt on the other side of the wall. The tieback system accomplishes two things: it keeps dirt from filling into the pit and it keeps the Court building’s foundations secure. The Court buildings have not moved more than a sixteenth of an inch during our construction process. At the base of the pit a foundation was poured out of concrete, in late November and early December, in preparation for the installations of a 160 ft. tall tower crane. The tower crane is used to pour concrete for the rest of the building including the walls and ceiling.

The sidewalk on the north side of E Street NW is open and provides safe accommodations for pedestrians during construction. Signs will be posted to direct pedestrians to cross to the north sidewalk of E Street to avoid the construction activity.

The National Law Enforcement Museum, a project of the National Law Enforcement Officers Memorial Fund, is a 57,000-square-foot Museum which will be located adjacent to the National Law Enforcement Officers Memorial in Washington, DC’s Judiciary Square. The Museum will tell the story of American law enforcement through high-tech interactive exhibits, comprehensive collection of artifacts, extensive resources for research, and diverse educational programming. The Memorial Fund’s mission is to tell the story of American law enforcement and make it safer for those who serve.
