499.03.01 Schedule. As a first order of work, prepare and submit a schedule for the submission

of the working drawings as specified in 499.03.02 or 499.03.03. Coordinate the schedule with and in full accord with the Progress Schedule submitted to the procurement officer as specified in GP- 8.04 and TC-5.02. The schedule shall include each type of working drawings (e.g. form plans, structural steel, etc.), approximate number of drawings to be reviewed, estimated date of first submission, and estimated rate of submission of drawings (e.g. 5/wk). Where possible, submit the most crucial drawings first with sufficient time for review to minimize delays during construction.

499.03.02 Consultant Engineering Firm. When the Contract Documents specify that a

consultant engineering firm is to review the working drawings for the structure, send all working drawings to that firm. To expedite the checking and distribution of working drawings, the Contractor, fabricator, or supplier may send electronic PDF versions or hard copy prints of their submissions directly to the appropriate consultant engineering firm, with copies of all correspondence to the Contractor, Director-Office of Structures, and the District Engineer. If the Contractor requests that all plans be routed through the Contractor’s office, then the establishment of that procedure should be the first order of work in order to avoid possible misunderstandings as to the processing.
