Renovating a facility is a complex undertaking. Properly communicating the project design to clients, contractors, and authorities is the goal. Even the generic term “Renovating” can be incorrect for particular projects. Defining appropriate building code and life safety terminology begins with model building codes and standards. These model building codes and standards are adopted by States and other authority having jurisdictions (AHJ) like the Department of Defense (DoD) or General Services Administration (GSA).
