| 1. Prefabricate structures. |
- Advance purchase of standard sections.
- Box type structures (concrete and steel).
- Offsite staging (portion of the cemetery).
- Bridge movement systems technology.
|
|
| 2. Technologies. |
- Use of high-performance materials.
- Use of integral pier caps.
- Use of lucite barriers.
- Use of proper wall types.
|
|
| 3. Willingness to mix and match to minimize impacts. |
- Environment.
- ROW.
- Motoring public, etc.
|
|
| I. "Get In and Get Out" |
| 1. Bridges. |
- Prefabrication of any bridge, bridge elements, and structural systems.
- Advance purchase and fabrication of structural components.
|
- Advance purchase/fabrication of structural components includes:
- Superstructures.
- Deck systems (i.e. Inverset).
- Substructures.
- Roll in railroad structure.
|
| 2. Walls. |
- Retaining walls are selected based on construction speed and design needs.
|
- Types of retaining walls considered:
- MSE walls.
- Sheeting with or without façade.
- Post and panels.
- Modular walls.
|
| 3. Technology. |
- High performance concrete and high performance steel (HPC and HPS).
- Bridge movement system to expedite construction.
|
- The use of HPC and HPS will result in lighter loads and shallower system.
- Types of bridge movement system:
- Self-propelled modular transport.
- Girder launching/skidding.
- Roll in.
- Vertical lifting.
|
| II. "Stay Out" |
| 4. Stay out. |
- Use of HPC and HPS.
- Inspectibility without impacting traffic.
- Future redecking.
- Automated deicing on deck of big bridge and flyovers.
|
- Use of HPC and HPS will result in low maintenance of structures and offer quality and durability to finished product.
|
| III. Miscellaneous Project Issues |
| 5. Miscellaneous project issues |
- Design with these items-lock in transportability.
- Set construction duration.
- Project wide Web-based electronic communication plan.
|
- Use of electronic shop drawings and electronic design submittals will expedite design process.
- Web-based electronic communication plan will keep the motoring public informed.
|
| IV. Suggestions to Alternatives |
| 6. Suggestions to alternative D. |
- Investigate depressed ramp "C" and make ramp "D" flyover.
- Investigate eliminating ramp "F" by combining with ramp "D" and bring it to the big bridge.
- Investigate taking all I-295 traffic off SR-42 NB at missing move ramp.
|
|
| 7. Suggestions to alternative K. |
- Tunnel carry I-295 traffic under I-76.
|
- This alternative is not preferred due to:
- High initial and maintenance costs.
- Ventilation, lighting, and fire code requirements.
- Security issue (target for terrorist attack).
- Trucks carrying flammable/contaminated materials cannot use the tunnel.
|
| 8. Suggestions to alternatives G2 and H1. |
- Double stacking I-295 structures.
|
- This alternative is not preferred because it is extremely unpleasing visually. Looking at a 70-75-ft bridge and retaining wall will not be well received by the local community.
