19_Door_Design_Example.pdf

This is a design specification document for Beaufort County, South Carolina, detailing the structural design requirements for a security door system at Fort Fremont Preserve on St. Helena Island. The document presents technical drawings and engineering specifications for a powers bat gate design, including anchor details, vertical column cross-members with stiffeners, and dimensional requirements. The design illustrates a metal gate structure with specific measurements, including a maximum opening width of 10 feet and column spacing of 18 inches on center, constructed from A-36 steel with cross-braced members and anchor points. The specifications are provided on a not-to-scale basis and reference additional notes for implementation details and material standards.

The document serves as technical reference material for the Design-Build contractor selected to fabricate and install security doors and window systems as part of the broader Fort Fremont Stairs and Rails Design/Build project. This specification supports the County's objectives to improve public safety and pedestrian circulation, enhance accessibility along the fort battery, protect historic structures, and provide secure enclosures for designated exhibit rooms while maintaining the historic and visual character of the preserve. The technical drawings establish baseline design criteria that the selected contractor must meet or exceed in their fabrication and installation work, ensuring compliance with applicable codes, standards, and the project's preservation requirements.
