MGMT-01 is a collection of 3 master files related to Owner-Architect contracts: a Contract, a Letter of Engagement, and a Supplemental Authorization.
These documents were introduced in the earlier posts linked above. Hopefully you will get some useful ideas about contracts themselves or the process that can make it easy to manage getting a written contract.
The Letter of Engagement is a simple way to get an agreement as soon as you are asked to start work. It contains enough Terms and Conditions to lay a decent groundwork for your legal relationship with your client. Because it describes how you will get paid, it also is a good test to see if the client is for real. This Letter of Engagement is intended to be supplanted later with an AIA (or similar) contract; or with the Contract included here.
The third template is a simple one-page authorization form that you can use when the inevitable change in scope occurs or when additional services of another kind come up. This form gets the cost ramifications on the table as simply as possible.
