I. Design Criteria Review
The conceptual design process was guided by the Defense Metals Technology Center (DMTC) and CSX Transportation (CSXT) and local building code requirements. It was critical for the design team to calculate both aspects into the design for a successful project. In doing so, this design integrates all necessary requirements.
A. DMTC Requirements
The DMTC has required all the structural components to be Titanium, be it
commercial or armor grade. Also during the orientation lunch, the panel
requested a United States Titanium supplier to help support the national
economy. On the side of the Quaker Square Inn, the bridge must also tie in with
the second floor balcony to allow elevator access for the handicapped. Finally,
the panel recommended the opposing side of the bridge allow potential
integration with a new building but currently exit the deck onto the parking lot.
B. CSXT Requirements
The CSXT requirements were far more complex for traversing the Right of Way
1(ROW) of the tracks. The most pertinent requirements are noted as:
1. Clearance- The standard horizontal clearance is typically 25’ but no
less than 18’ perpendicular to the tracks. The vertical clearance
standard measured from the top of the track to the lowest point on
the bridge shall not be smaller than 23’.
2. Drainage- Drainage from the bridge shall be collected by drain pipes
and cannot dump inside of the 25’ clearance mark.
3. Pedestrian Bridge Specific – No intermediate piers are permitted
between the tracks and bridges must be completely enclosed to
