Supply two bridge designs for consideration by the Chancellor
Discuss certain advantages and disadvantages of each design and their different cost to the University
Bridge DesignsBridge Designs

Walkway– Cement with brick railings.
Steps – Brick and cement with a stainless steel,
mirrored finish railing.
Bridge Design 1Bridge Design 1
Design 1Design 1
Advantages
1. Very simplistic stair and walkway
arrangement
Disadvantages
1. Necessary to build two of these designs to solve the problem
2. Costly
3. Time consuming
Bridge Design 2Bridge Design 2
Design 2Design 2
Advantages
1. Single bridge that would cross both roads
2. Aesthetically pleasing
3. Cost effective
Disadvantages
1. Length must be greater than that of Design 1
Bridge Cover OptionsBridge Cover Options
Clear glass or Plexiglas– Campus can be seen in the background– There will be some additional maintenance to
keep it clean
Chain link fence – Prevents objects from falling on to the roadway
but will not offer much protection
If Bridge is Covered…If Bridge is Covered…
Ventilation System– Provide air circulation– Passing smokers will likely be inclined to stop
under the covered bridge during poor weather.
Drainage system – Prevent standing rainwater.– Tied into the sewer system to prevent any
pollution.

TimeTime
Estimated time for the completion of the project is 30 to 45 days.
Design 1 will take longer than Design 2 because more construction will be necessary.
RecommendationsRecommendations
Bridge DesignBridge Design
Design 2– Aesthetically pleasing – Cost effective for the campus – Almost identical bridge at the University of
North Carolina Campus in 1993 and no reported problems
OptionsOptions
Cover– Plexiglas top
Ventilation System
Drainage system
Construction TimeConstruction Time
During the summer – Approximately 30-45 days– Road will have to be temporarily closed– Fewer students will be on campus
