The Contractor is responsible for noting all changes and corrections on the master/record construction drawing prints promptly as the changes occur in red ink (redline prints) and note the dates when these changes occurred; in no case less often than on a weekly basis. The master/record construction drawing prints shall indicate all the changes and modifications incorporated into the work as well as the following:

5.1.1 Actual locations of all subsurface and concealed utility lines after completion of any performed subsurface surveys. In order that the location of these lines and appurtenances may be determined in the event the surface openings or indicators become covered or obscured, the master/record construction drawings shall show the actual locations by offset dimensions via two permanently fixed surface features. Appurtenances shall be located by dimensions along the utility run from a reference point. The average depth below the surface of each run shall also be recorded as applicable.

5.1.2 Shop drawings that constitute part of the design shall be included with the record drawings.

5.2 The master/record (redline construction drawings) prints with corrections, such as field changes and contract modifications, shall be certified by the Contractor as to their correctness and shall be submitted to the Contracting Officer’s Representative for approval. After the provisional master/record (redline construction drawing) prints are approved by the COR, the COR will obtain a compact disc (CD) of computer-generated construction drawings from the DPW Engineering Service

Division, Building 1021 at Hunter AAF. The Contractor shall then transfer all corrections from the redline construction drawing prints to the compact disc (CD) of computer generated construction drawings. Corrections done shall be executed in MicroStation “.dgn” format. The Contractor shall note on the computer generated construction drawings the words “AS-BUILT” in the revision block with the next revision number to identify any changes made. The revision number identification will be placed to annotate the respective changes on the drawings. The Contractor shall then submit the AS-BUILT compact disc (CD) of computer generated drawings and one (1) AS-BUILT hard copy with the Contractor’s redline corrections to the COR to insure accuracy and that all corrections were transferred from the redline construction drawing prints to the AS-BUILT hardcopy prints.

After COR approval of the AS-BUILT hardcopy prints, the COR will deliver the package to the DPW/ESD/Drafting section for final approval of the AS-BUILT compact disc (CD) of computer generated drawings. At this time, the Contractor will receive final payment contingent on approval by the COR.
