Incentive/Disincentives (ID) Program
The use of Liquidated Damages (LD’s) as an enforcement tool for work completion is not a success.   For some projects, the reliance on LD’S is simply a path to failure for timely performance.  I/D’s are designed to enhance the project LD’s and encourage contractors to view the project with high importance to the completion schedule.
Objectives of this Site
  • Evaluate the project need for an I/D
  • Organize the process for developing I/D's
  • Calculate the dollar range of I/D values
  • Assist the selection of the best I/D amount
  • Document the project team decisions
