Bridge Falsework Forum October 15, 2007 Page 4 of 6

4.

4. 2. Discussion - Traffic windows issue is critical. In the past, before late openings of traffic closures had fines attached to them, the contractor and the Structure Representative ensured that the falsework was safe prior to opening, even if it meant delaying the opening. Now with delays costing thousands of dollars per minute, the joint effort and extra care that went into the project before it was opened to traffic seems to have disappeared or is greatly reduced.

4.

4. 3. Implementation - Implementation of these “requirements” would probably have to be made as changes to the Contract Standard Specifications or the Special Provisions.

5. Best Practices (Internal by Contractor)

4. 5. 1. Training - the more you can get scheduled, the better off we all will be. There are not enough people available with experience. (Laborers, Carpenters, Pile Butts etc…) The Union offers some basic falsework training.

4.

5. 2. Company Certification - As contractors are using different systems, individual contractors should do internal training and certification. Some contractors are already doing this.

4.

5. 3. Implementation - This could be required by Spec or as a Best Management Practice in the Falsework Manual.

6. Rewrite Falsework Manual, Bridge Construction Memos, Specifications

4. 6. 1. Longitudinal Stability Analysis – Add more examples to the falsework manual

4.

6. 2. Friction Transfer Capacity (FTC) Allowance – Doing away with it was proposed.

4.

6. 3. Testing and use of clamps – C-clamps are sometimes being used improperly. Clarify limits of use in the falsework manual. Provide basis for use and capacity via testing.

4. 1. 2.Onsite during grading operations - Consider having the falsework engineer there (on-site) when any adjustments or grading are being done, not just to certify the falsework before opening to traffic. Having the falsework engineer on site to approve the falsework just before we have to open to traffic is not practical. It is not realistic to have us hold traffic on major interstate, given the penalty. This is why it is essential to set and meet milestones during the operation.

4.

4. 1. 3.Progressive stages of construction - There are a limited number of falsework designers, it is not possible for the actual designer to be on site at all of the “critical” stages of falsework Construction.
