13、tractor and Government activities. It will also be used to report progress and evaluate time extensions. If cost-loaded, it will provide the basis for progress payments.The Contractor shall use the Critical Path Method (CPM) and the Precedence Diagram Method (PDM) to satisfy time and cost applicatio

14、ns. For consistency, when scheduling software terminology is used in this specification, the terms in Primaveras scheduling programs are used.1.2 SUBMITTALS*NOTE: Review Submittal Description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES. Edit the following list to reflect only the submi

15、ttals required for the project. Keep submittals to the minimum required for adequate quality management and Government construction management activities.A “G” following a submittal item indicates that the submittal requires Government approval. Some submittals are already marked with a “G”. Only de

16、lete an existing “G” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.*The use of a “G“ following a submittal indicates that a Government approval ac

17、tion is required.
