April 6-8, 2004, Knoxville, Tennessee
Appendix B (continued): Skill Set Reporting Forms
Construction, Materials, Accelerated Testing, Constructibility
| IDEA (Short Name) |
IDEA (Detailed Description) |
Implementation Details (Barriers, Skill Set Coordination, etc.) |
| Preconstruction and Utilities |
- Accelerate utility relocation by authorizing in advance of construction *
- Accelerate permit process
- Railroads double shifts
- Partial opening of I-40
- Co-location of offices for field inspection coordination
- Coordinate construction of other facilities
- Suggest (not mandatory) material storage near railroad and port
- Identify all work on the critical path that can be done in advance of closing I-40 (i.e., ramps, foundations)
|
- Usage of SUE procedures to minimize delays.
- Coordination time and in-house resources are barriers.
- Coordination with railroads to prevent delay is a barrier.
- Assumption that I-640 can handle the deferred traffic is a barrier. Worker safety is another barrier.
- No barriers.
- This needs to be coordinated with traffic.
- No barriers.
- Develop critical path.
|
| Materials |
- Use of high early strength concrete
- VECP
- Non-destructive testing (maturity meters)
|
- Need to make sure that it is necessary (justify the additional cost).
- No barriers because this is a standard special provision of the contract.
- Specification change and (for maturity meter, increased production monitoring) are barriers.
|
| Bridges |
- Adjust span lengths to avoid existing foundations, and install spread footings and/or pin pile foundation under the JWP before demolition.*
- Use of precast pier caps, bent caps, and post-tensioned/precast columns
- Use of continuous pours for deck slabs on prestressed beams
- Greater cover in lieu of epoxy coated rebars to avoid painting holidays and speed construction
- Use of high early strength concrete, particularly for deck slabs
- Preassemble structural steel in sections and launch or lift into place
- What needs to be done to coordinate the movement of cranes and overweight specialty equipment across pavement and bridges during construction
|
- Confirm that foundations will be spread footings and/or piles.
- Needs to be investigated and developed if approved.
- No barriers.
- Philosophy changes.
- Philosophy changes.
- No barriers.
- Coordinate and approve.
|
| Pavement |
- Alternative Pavement:
- Usage of long-life pavement
- Noise reduction
- Service life
- Use same structure for shoulder and pavement
- Use of alternative pavement in the bidding process
|
- Cost factor would be a barrier on using pavement with longer life. How much pavement can be stacked on top of other pavement is another issue.
- Cost is only barrier.
- Establishing the contract document in bidding is the barrier.
|
| Contract Administration |
- Let contract early before I-40 closure for prep time
- Specify shop draw approval time limitation
- Use of one contract instead of breaking down
- Work multiple shifts
- Develop overall schedule (CPM) for all included commitments, not just job schedule *
- Use of incentives/disincentives, A + B,* warranty
- Construction management coordination of all contracts
- Contractor quality control process
- Rating contractor performance
- Establish dispute resolution board
- Include price adjustment clause
|
- Paying of a premium and stockpile payment are barriers.
- Specification of development is another barrier.
- The barriers are funding, project delivery, and time.
- Local ordinances (noise restrictions, etc.) need to be checked. Coordinate with city and county.
- In-house resources are needed.
- Bonding companies for the warranty can be a barrier.
- Coordination is needed.
- Establishment of a new process is the barrier. Change partnering specification is another barrier.
- New process that has to be developed and established.
- Establish indexes for steel and write specification.
