Contemporaneous documentation refers to the files created “at the time.” On a construction project, these are the letters, memos, e-mails, requests for information (RFIs), change order requests (CORs) change orders (COs), project invoices, plans, specifications, job site photos, job site videos, inspector reports, and any other documents that chronicle the status of the project and were created during the actual construction.
This is distinguished from documents such as deposition transcripts which chronicle people’s memories of the events of a project after the project has been completed.
Unfortunately, our memories can be less reliable than we would like to believe. Administrative workers, project staff, engineers, superintendents, project managers, all have different views of a project and will remember key events in a variety ways. Additionally, memories can change over time as folks hear the stories of others. Therefore, contemporaneous documents are the best source available for reconstructing the facts of a project if a dispute arises.
