Preserve Engineers developed a comprehensive parking garage stair tower repair and replacement program for the multi-level stair tower at the 111 S Church St Parking Deck in Charlotte, North Carolina. The existing steel stair system exhibited deterioration associated with long-term exposure, requiring a coordinated structural restoration approach to improve durability and maintain safe pedestrian access.
Our team prepared construction documents for replacement of the aging steel system with galvanized steel stringers, SlipNOT perforated treads and risers, new landings, guards, and handrails. The project also includes wall coatings, localized concrete repairs, supplemental steel connections, temporary egress provisions, and carefully coordinated construction phasing.
Structural Steel Stair Replacement
The replacement stair system was designed to improve long-term durability while reducing future maintenance requirements. Galvanized structural steel was selected for the primary stair framing, with slip-resistant stair components incorporated to provide durable pedestrian access within the active parking facility.
Preserve also developed supplemental connection details and coordinated the new stair framing with the existing parking structure. The repair design addresses both the deteriorated stair components and the interface between the new steel system and the existing concrete structure.
Construction Phasing & Temporary Egress
Because the parking deck must remain operational during construction, the repair program includes carefully planned sequencing and temporary egress provisions. Preserve coordinated the stair replacement to maintain safe pedestrian circulation while allowing the contractor to systematically remove and replace the deteriorated stair system.
Following completion of bidding, Preserve is providing construction administration and field engineering support, including review of submittals and field conditions, contractor coordination, and observations of the work as construction progresses.
