Types of Supplemental Agreements
There are two types of Supplemental Agreements (SA). Which one you use depends on the urgency of getting the supplemental work started.
Standard Supplemental Agreement
Use standard SA when there is time to execute the SA, get the appropriate original signatures and encumber funds before beginning work.
This is the preferred SA method.
Supplemental Agreement - Parts A + B
Use SA – Part A & Part B when work needs to be authorized quickly. Work can start sooner since this method allows faxed signatures in Part A. Part B mimics standard SA but it can be completed at a later date.
Check sample SA language which can be used in either type of SA.
