Scope/Solutions
Children’s National undertook a project to improve the entry experience into the hospital. The work included replacing the original inclined moving walkways with a grand stair and three new elevators connecting the hospital’s main level to the below-grade parking garage. SGH provided structural engineering services for the project.
Highlights of our work include:
- Coordinating a subsurface investigation to determine existing soil properties for design of new foundations
- Participating in a pre-design phase to evaluate the structural implications of removing the inclined walkways and the advise the hospital on proposed replacement options
- Evaluating the feasibility of raising the parking garage ceiling height
- Preparing structural demolition plans
- Designing structural strengthening and modifications, including new floor openings, precast concrete plank and structural steel infill framing, and foundations to support the grand stair, elevators, and the elevator lobbies at three levels
- Providing construction administration services and helping the project team address field conditions during construction
