O&S performed engineering and parking consulting services for the structural restoration and preventive maintenance of a four-story, 520-vehicle parking garage serving the employees and visitors of the Sacred Heart Hospital Buildings, located in Pensacola, Florida. The parking garage is of a cast-in-place (CIP), post-tensioned (PT) concrete structural system. A few conditions of structural deterioration typical of cast-in-place concrete framed parking garages were observed. These include limited floor slab cracking and spalling, spalling of concrete framing with locations of advanced deterioration developed at the several sections including stairwells.
O&S was retained to perform a condition assessment and develop a program of requirements for restoration of the parking garage. O&S performed a comprehensive visual survey of the garage and devised a restoration program that addressed the concrete deterioration of the floor slabs, beams, columns, as well as the exterior façade. A complete waterproofing program was also devised to mitigate water infiltration and through slab leakage. Our recommended cost budget was $2.67 million. After we submitted our Comprehensive Condition Survey report, the hospital asked us to break the original scope of work and include only priority repairs at the stairwells as part of Phase 1 to accommodate existing budgets. Upon submitting the stairwell repair program, the hospital engaged us for design services to develop repair documents for the proposed Phase 1 restoration program at both the North and South stairwells.
Construction work began in late-2021 and was completed mid-2022. As part of the work, an alternate steel framed temporary scaffold stairwell was provided to accommodate pedestrian traffic while one stairwell was closed for construction. Repairs at the stairwells mostly included removal and replacement of deteriorated and failing thin-gauge metal pans and the infill concrete. Several heavily corroded steel beams and columns were replaced or strengthened with supplemental welded steel plates. The project was performed in conjunction with our design-build partner Weatherproofing Technologies. O&S was engaged to assist in bidding services and to provide technical supervision throughout the project.
