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)

Pontons will be inspected for leakage at

least once every 3 hours during heavy

traffic.

Debris will be cut from or removed from

the water to ensure safe travel.

Roadway pontons will be washed downperiodically of mud, dirt, rocks and
