Franklin Field was originally constructed in 1895 as a venue for athletic events. The lower section of reinforced concrete bleachers was added in 1922, and the steel-framed upper grandstands added in 1925. The addition of the upper grandstands created the first modern, two-tiered football stadium, in the United States. Since 1925, Franklin Field has hosted Ivy League sporting events, political events, NCAA Championships, Philadelphia Eagles games, University commencement, and the Penn Relays. After nearly a century of service, the reinforced concrete in the upper and lower grandstands had deteriorated and needed a comprehensive restoration to extend the service life of the structure. This submission addresses Phases 2 to 6 of the restoration program, which were completed between June 2019 and January 2022.

Development of the restoration plan required evaluation of the performance of prior repairs, review of repair options, owner consultation to gauge tolerance for future maintenance, and to determine the owner’s desired service-life of the repaired structure. These discussions led to a restoration plan designed to provide a minimum expected service-life of 25 years, with routine condition surveys, maintenance, and the replacement of sealants and coatings over time. The final repair design for Franklin Field was developed in accordance with the requirements of ACI 562–16.

Extensive repairs were required to address concrete spalling due to reinforcing steel corrosion, with most of repairs located at or adjacent to previous repairs. Repairs were largely designed to be full depth, with the repair material selected to match the original concrete properties. Access limitations at the stadium resulted in all repairs being completed using pre-packaged concrete materials, placed by hand, largely using 5-gallons buckets for concrete transport. The project had an overall budget of $38.3M and was completed on time in January 2022, at a final cost of $37.2M.

This project consisted brick replacement, arch reconstruction, brick repointing, granite repointing, masonry cleaning, caulking, & anti-bird protection. The restoration of the historic brick along arch street commenced in 2019 and is part of a three-phase restoration campaign. The other phases are the restoration of the cast iron and wood windows on the east façade, in progress, to be completed in spring of 2022, and the restoration of the cast iron and wood windows on the west façade, to be completed summer 2022.

The extant condition of the brickwork prior to the restoration was poor at best. The bricks were a soft yellow variety. Faces had spalled off, entire sections eroded back to the substrate, and bio growth and carbon staining had taken ahold of large sections. Included in the damaged areas were the famous load bearing arches that lined Arch Street.

One of the first steps was to determine and source the historically compatible materials to be used. Mortar analyses were conducted to determine the proper mix designs. Two custom mortars were developed. The brick joints were a butter joint and only 1/8 of an inch or less. Marble dust was used as the aggregate and it was custom pigmented to simulate the original mortar color. The granite had a joint on average of 3/8 of an inch so a blend of sharp, clean and well graded sands were used. This was also custom pigmented to simulate the original mortar color.

The replacement brick had to be custom made as well. The façade has several unique shapes in the decorative horizontal band as well as the larger arch bricks. A specialty manufacture and supplier was utilized to create all the replacement bricks.
Once materials had been established, the tedious work of removing and replacing the brick while balancing keeping the historic fabric of the building intact and working on a busy city street could be carried out. Special tools were used and even created or modified to deal with the difficult task of cutting out the mortar in the tiny butter joints without damaging the existing brick. The structure was then cleaned using a mild detergent and low pressure washing.
