From page 16... ... 16 Development and Use of As-Built Plans by State Departments of Transportation "The Record Plans consist of the original drawings on which all construction details which differ appreciably from the original design are shown in the color red. Record plans constitute the permanent record of exactly how the project was actually constructed for future reference and information." "As-Built plans are the 'As-Awarded' project plan sheets that have been updated to reflect the changes, if any, which occurred during construction. Read the entire page →
From page 17... ... Survey Results 17 Methods Used to Capture and Document Changes During Construction Another area of interest involves the methods used by STAs to capture and document changes made to the original project plans during construction. Respondents were asked to pick from a set of preselected methods developed from the literature review. Read the entire page →
