Contract Modification Management Process
For Iowa DOT Contracts
1. Contract Modification required to accomplish the original concept of the project (i.e. omitted items, plan deficiencies, unforeseen conditions, etc.)
2. Contract Modification required to enhance the original approved project concept (i.e. incorporate new standards or details, etc.)
3. Contract Modification to accomplish other work rather than following the normal development process. These typically are an extension of the project limits and result in selecting contractors on current contracts rather than awarding contracts by the low bid process.
