Additional Time Guidance

Per FHWA, method 3 for adding time should rarely be used. Discussion of additional time needs to take place with the contractor. This may be done by reviewing when work will take place on the most recent accepted project schedule.
Questions to consider include:
  • Is the CO work on the critical path or affects current and downstream critical path activities?
  • Will a crew need to be pulled from a critical path activity to do the CO work?
  • Is a crew available to work off critical path for the CO work?
  • Can a crew from a different project be mobilized to perform the CO work off critical path? Will involve negotiating additional cost.
  • Will additional barricade months be needed? Be wary of contractor requesting to move work to end of project.
  • Is float time available to mitigate some or all of the needed time?
  • Is the extent or impact of the change order work able to be estimated?
Document the information and then work to resolve the time issue as soon as possible (not at the end of the project).
