Crane Flat Yosemite Institute Campus Dining Hall Egress

This project entails the installation of a new fire egress door on the dining hall at Yosemite Institute's Crane Flat campus. The dining hall currently has a maximum occupancy of 49 people, while the campus current bed capacity is 84 (76 program, 8 staff). The addition of a dining hall egress door is the final step planned in the compliance review process.
Through consultation with National Park Service Fire Management (Don Coffman and Deron Mills), Yosemite Institute (YI) has developed plans for installing a new doorway in order to increase the occupancy of the dining hall, with a target of 85. The exact number will be determined based on a site visit after the construction is complete. Such an occupancy would allow YI to shelter all its program participants (plus staff) during emergencies or inclement weather, which is the American Camp Association standard currently not being met.
Based on the fire code recommendations and a site visit with the park Historic Architect, YI has determined the most ideal location for a new 36" exit door. The installation will require modifications to the roof, to allow the egress to be clear of snow during the winter. The increase in capacity will also require installation of acceptable exit signs and emergency lighting, as outlined in the fire code.
The egress will be a 36" inch door, covered by a 6' x 4' section of 12/12 pitched gable roof. 8' of boardwalk will extend from the building outwards to grade, providing building accessibility. All materials will be selected to match existing materials on the dining hall.
Plans will be reviewed by park Historic Architect prior to the building phase.
YI will submit a safety plan to the safety office for approval before beginning work on this project.
This project will involve minimal ground disturbing activities. The foundation for the decking will require setting eight concrete foundation pier blocks that measure 12" x 12", and will be buried to a maximum depth of 8". Ground disturbance will include digging, leveling and compacting soils under the blocks, and some minor grading work to transition from decking to grade, which will meet accessibility standards.YI will consult with NPS archeology and the Native American Liaison prior to ground disturbing activities.
YI will consult a structural engineer for written recommendations concerning the best design for snow load considerations.
