Assembly Time for
Ribbon Bridges
Example 1
How much time is required to construct a 500ft
ribbon bridge during daylight operations?
500ft divided by 600ft per hour =.833 hours(day)
Convert .833 to actual time.833hrs x 60min =49.98 round up 50 minutes
Example 2
How much time is required to construct a 500ft
ribbon bridge during night operations?
500ft divided by 600ft per hour =.833 hours(day)
Convert .833 to actual time
.833hrs x 60min =49.98 round up 50 minutes
(Construction by night add 50 percent).833hrs x 30min =24.99 round up 25 minutes
50min + 25min = 1 hour 15 minutes (night build)
