The Standard Input (SI) contains some generic information required on every project. For example, the SI contains contact office location for all three regions, the designer chooses only one of the three based on the location of the project, etc. The SI also includes the approved changes to the Specifications until they are incorporated in the next publication of the Specifications. The designers use the SI as a template to prepare project specific Special Provisions, which are part of the Contract Documents. The Standard Input Guidelines provide information on how to utilize and make changes to the Standard Inputs.
