Robert A.W. Carleton Strength of Materials Laboratory. Robert A. W. Carleton Strength of Material Laboratory (Carleton Lab) is a civil engineering materials testing laboratory affiliated with the Department of Civil Engineering and Engineering Mechanics (CEEM) in the Columbia School of Engineering and Applied Science. The laboratory is located on Columbia University's Morningside Heights campus in the City of New York. Carleton Laboratory provides educational facilities for the CEEM Department, supports research of infrastructure and principles of engineering, and conducts specialized testing of materials used in infrastructure in the City of New York and internationally.

Overview 

Carleton Lab, an endowed research center overseen by the Trustees of the Robert A. W. Carleton Laboratory, is one of the largest labs on Columbia’s Morningside Heights campus.

Within the lab, students may participate in hands-on engineering testing through courses such as Soil Mechanics, Experimental Soil Mechanics, Structural Assessment and Failure, Experimental Mechanics of Materials, Fluid Mechanics, The Art of Engineering, and Independent Study courses. The lab hosts the Columbia University chapter of the American Society of Civil Engineers/American Institute of Steel Construction Steel Bridge competition.

History 
Robert A. W. Carleton graduated among the Class of 1904 with a degree of civil engineer from the School of Applied Science. After graduating, Carleton served as the lifetime Class President of the Class of 1904; Chairman of the Columbia University Engineering Center Fund Committee, the committee responsible for raising the funds to build engineering and science buildings on the Northeast corner of Columbia University's Morningside Campus; President of the Columbia Engineering Council; and a member of The Society of Older Graduates of Columbia.

Carleton also co-founded The Carleton Company, Inc. in the 1920s. The engineering firm that took part in the construction of the Pennsylvania Railroad, Long Island Railroad, the New York City Subway that ran under Eighth Avenue and Sixth Avenue, and the Holland Tunnel. Carleton was lauded for his ability to work on these transportation hubs without interrupting regular service. In 1941 Carleton negotiated with the United States Government so that The Carleton Company Inc. could build the largest receiving and distributing centers to support war efforts by facilitating the transfer of materials during the Second World War.

Robert Carleton was appointed the head of the Engineering Center Development Fund Committee, which oversaw the fundraising and design of what would become the Seeley Wintersmith Mudd and the Engineering Terrace buildings. Under his leadership, construction of the facility was completed in six months. On 4 April 1959, Carleton was awarded the Egleston Medal, Columbia University’s highest award for distinguished engineering achievement due to the breadth of engineering work undertaken during his career.

In 1962, the Trustees of the University authorized the establishment of the Robert A. W. Carleton Strength of Materials Laboratory in the department of Civil Engineering and Engineering Mechanics, due to the support of Robert A. W. (1881–1971) and his wife Christine S. Carleton (1905–1983). Eight years later, the Columbia Engineering Alumni Association commissioned a portrait of Carleton, painted by artist Lester Bentley. The painting was dedicated and given a place inside the Monnell Engineering Library in the Seeley W. Mudd Building in December 1970. This painting has since been moved into Carleton Lab and placed at the top of the staircase on the main floor.

Robert A. W. Carleton died in 1971, but his wife continued to support Carleton Lab and Columbia Engineering in her husband’s name until her death in 1983.
