Boston Red Sox


Fenway Park, opened in 1912, is the oldest stadium in Major League baseball and home to the Boston Red Sox. The structure is comprised of a concrete frame, tread and riser sections in the seating bowl, and steel supported upper levels constructed of precast concrete supporting a metal deck and concrete slab.


WJE's thorough visual inspection of the seating bowl revealed numerous cracks, spalling, loose concrete, and open joints—all allowing significant water infiltration throughout the structure. To mitigate the deterioration, WJE engineers developed several waterproofing options and installed mock-ups of each to determine through field tests which would provide the most effective barrier. Based on the findings, WJE offered recommendations to the client that were both technically appropriate and historically accurate.

For the severely eroded Loge and Field Box, WJE oversaw the installation of a concrete overlay to restore the deteriorated concrete and to create a monolithic surface that will limit future water infiltration. The Bleachers and Grandstand displayed a lesser degree of deterioration due to their protected location beneath the roof and upper deck; thus, WJE recommended a less invasive waterproofing membrane system to minimize their existing exposure to water and to improve the overall appearance of the seating bowl.

In addition to the structural repairs, WJE also increased and reconfigured seating capacity, restored existing handrails, and replaced plastic seats with historically authentic wooden seats to recapture the original aesthetic atmosphere of the iconic ballpark.
