In May of 1922, Turner began construction on Franklin Field, a multi-purpose sports stadium for the University of Pennsylvania. The reinforced concrete and brick stadium was the first Turner built in Philadelphia, and the second sports stadium the company had ever constructed – the first being a football stadium for Harvard University in 1909. Franklin Field was to be substantially completed by the beginning of the football season, just five months after its groundbreaking. From the beginning, Turner had a team of 400 men on the job working 6, 12-hour shifts a week to demolish the wooden stadium that the University had built 27 years prior, forming and placing more than 10,000 cubic yards of concrete and finishing the exterior with over 2 million bricks. The 50,000 seat stadium was dedicated during halftime of the second game of the season by United States President Warren G. Harding. The success and speed of construction secured Turner’s prominent role in the construction of a sports stadium for the city of Philadelphia in May 1925. Municipal Stadium was completed in July 1926, dedicated on the 4^th of July by U.S. President Calvin Coolidge and could accomodate 100,000 spectators.

Turner was contracted again in July of 1925 to build a second tier for Franklin Field, increasing the seating accommodations from 50,000 to 77,000. The second tier was also made of reinforced concrete and brick, but made even more structurally sound by supports made of steel. Since its expansion, Franklin Field has been host to countless numbers of sporting events, including the Penn Relays, the Army/Navy football game between 1899 and 1935, and the Philadelphia Eagles, Temple Owls and Penn Quakers. The first rugby league match between the US and Australia was also played at Franklin Field, with the Aussies nudging out the Americans 36-24. Irish band U2 headlined their first public concert at Franklin Field in 1997. Franklin Field has also held prominent placement in the film Unbreakable as well as Invincible, where it was used as a stand-in for Veterans Stadium.
