Construction submittals are items that the contractor sends to the project engineer in the construction field office for review and approval. Problems arise when the construction schedule is negatively impacted because submittals are either received late, incomplete, or deficient from the contractor. A lean tool, value stream mapping (VSM), and various other lean concepts were used to analyze the submittal review process for a typical levee construction project. Through the application of lean concepts, measurable savings in process and lead times are obtainable by reducing or eliminating nonvalue activities.
