The Nebraska State Capitol features similar church vocabulary. The plan is a modified cross-in-square plan enclosed by a square. Four arms radiate from a central domed rotunda, upon which rises the tower with its unarticulated windows and flat surfaces—much like an enlarged spire. In March 1922, the Capitol Commission built an electric railroad spur from Lincoln's Burlington yards. The state-owned line ran along H Street from 7th to 14th Streets and provided an easy means for delivery of construction materials. Then on April 15, 1922, Governor Samuel R. McKelvie ceremonially broke ground, thus beginning a ten-year construction process which occurred in four phases. Building in phases allowed construction to commence before demolition of the old statehouse. With completion of the capitol's Phase 1 in 1924, state operations moved into the new structure. The old capitol was subsequently razed. On April 23, 1924—just two years into the capitol's construction—Bertram Goodhue died, and his associates formed a firm, Bertram Grosvenor Goodhue Associates, to finish the capitol and other ongoing Goodhue projects. After construction ended in 1932, the Capitol Commission hired Lincoln landscape architect Ernst Herminghaus to design the grounds. Bertram Goodhue employed two New York artists, Lee Lawrie and Hildreth Meière, in both the exterior and interior ornamentation of the Nebraska State Capitol. Lawrie, a sculptor, designed all of the engaged relief panels and buttress figures of the exterior, along with interior column capitals, doors, and fireplace surrounds. Meière, a muralist, designed the marble mosaic panels of the floors and the ceramic tile panels of the vaults. On January 20, 1922, the Capitol Commission requested Goodhue to consult with Dr. Hartley Burr Alexander, of the University of Nebraska's department of philosophy, "to work out the inscriptions to be used on the Capitol Building." In addition to the inscriptions, Alexander began to work closely with Goodhue and Lawrie on the themes of the exterior sculptures. When Goodhue died in 1924, Alexander feared that the thematic development in future portions of the capitol would be inconsistent with the established schemes. He therefore wrote an overarching thematic program, "Nebraska State Capitol: Synopsis of Decorations and Inscriptions," in July 1926. Alexander's synopsis thus served as a guide for the remaining interior and exterior decorations, and Alexander was bestowed with the title of Thematic Consultant.
