Prefabricated Bridge Elements and Design/Build
Safety Innovations
- Permanent safety features will be completed in both traffic directions within six months of beginning work.
- Lane closures will be limited to off-peak times to minimize traffic incidence potential during construction.
- Speed bands will be employed during lane closures using work zone law enforcement, allowing 75 percent of the traveling public through the construction zone within 5 mph of the posted speed and less than five percent at more than 20 mph over the posted speed limit during construction.
- Methods will be used to monitor and measure worker injury Incident Rate (ir) with the goal of having a worker injury IR of less than 4.0 based on the osha 300 rate.
Construction Congestion Innovations
- The project will minimize lane closure durations and employ methods for non-injury incident clearance time management within 20 minutes.
- The project’s fast-track schedule will minimize the number of construction days involving Interstate lane closures.
- Limiting Interstate lane closures to evening, night, and off peak daytime hours will minimize rural area queue lengths and construction congestion.
Quality
- The project will demonstrate the findings in fhwa-rd-02-057 Publication, Pavement Smoothness Index Relationships: Final Report that gdot is a leader among states in its smoothness specifications. The project will also provide an indirect but integral benefit in noise abatement.
- Prefabricated columns and caps, prefabricated deck panels, prefabricated culverts, and roller-compacted-concrete pavement on shoulders will be used for the bridge over Interstate 85. Encouraging the contractor to use innovative materials and technology as part of a pre-design proposal is new for gdot.
User Satisfaction
- Surveys will be conducted to obtain user satisfaction and approval ratings, with Georgia setting a goal of 80 percent.
