But Pack was merely the agent for the Cleveland Trust Company. Pack often served as the go-between in these types of investments so that wealthy investors wouldn't be gouged once sellers knew the identity of the purchaser. By 1904, Cleveland Trust officials had decided that this land would be a good location for their new, permanent headquarters. In 1904, the Cleveland Trust Company invited architects from around the nation to participate in a competition to design the headquarters building it intended to build on the First Methodist/Wedge land. In November of that year, the company selected New York City-based architect George B. Post to design the structure. Post was a nationally known architect whose works included the New York World Building (1890), then the world's tallest building; the Manufactures and Liberal Arts Building at the World's Columbian Exposition (1893), the Bronx Borough Hall in The Bronx, New York (1897); and the New York Stock Exchange building (1903). Post was already known in Cleveland for designing the Williamson Building (1900), an 18-story office building on Public Square. Salvage work on the existing buildings began in April 1905, and demolition of them in May. Demolition was halfway complete by June 18. By this time, Post's plans for the new bank building envisioned the bank itself taking up half the block, with an office building or trade center taking up the rest. The Cleveland Trust contracted with John Gill & Sons, a Cleveland construction firm, to build the new structure. Ground was broken on December 9, 1905, and construction was estimated to last 400 days. The estimated cost of the structure was $600,000 ($ in dollars). Construction on the building continued throughout 1906. Several serious accidents occurred at the construction site. On January 25, 46-year-old bricklayer Steven Johnson fell from scaffolding and fractured his skull and wrist. Engineer G.A. Donsee had his left leg crushed on June 19 when a high derrick fell on him. The third accident resulted in a fatality, when workman William Crouch died after being struck in head by falling debris on August 25. In April 1907, the builders estimated that the structure would be finished by November 1. But construction delays prevented the building from being completed until December 28, 1907. The Cleveland Trust Company occupied its new headquarters on January 1, 1908. The final cost of the structure had also risen substantially, to $1 million ($ in dollars). When completed, the four-story Cleveland Trust Company Building was the third largest bank building in the United States.
