The 1919 Market Street parking structure was designed as a precast garage, with five levels, a green roof, and approximately 400 spaces. Despite the logistical challenges associated with erecting precast in downtown Center City Philadelphia, the cost savings and shorter overall construction schedule associated with precast made it the best choice for Owner Brandywine Realty Trust. Shockey Precast’s Business Development Manager worked with General Contractor Hunter Roberts Construction Group and Engineering firm O’Donnell and Naccarato for nearly 18 months prior to award of the project to help develop a precast design that met the Owner’s budget and schedule. The Shockey Precast Group produced and hauled approximately 408 pieces of precast for the project, including 86,776 SF of double tes. With minimal to no on-site storage available, Shockey had to provide its own drop lot and jockey pieces to the site. Additionally, the building’s difficult footprint and unusual layout created complex challenges in terms of handling and erection of the precast components. Shockey worked extensively with the City of Philadelphia and erector Precast Services, Inc. to coordinate a two-lane shutdown on 20th Street that enabled PSI’s Union erection crews to use a larger crane for the precast erection.
