The Netherlands Carillon tower stands approximately 130 feet tall and houses 50 bronze bells. This tower was a gift to the United States from the Netherlands in 1954 as a thank you for its aid during and after World War II. The structure of the tower showed signs of deterioration and was in the early stages of structural failure. Langan provided site/civil, environmental, and geotechnical engineering for renovations to the tower. Langan also provided a 3D laser scan survey of the exterior and accessible interior spaces of the Carillon. Langan helped obtain the necessary National Park Service permits and approvals. To accomplish this, the A/E team coordinated with the Netherlands Embassy throughout the renovation to reconfigure the existing bells and elevate the monument to Grand Carillon status with the addition of three new bells.
