Standard Specifications, related to Working Drawings.

BDC01S-5

May 18, 2001

SUBJECT: Revisions to the 1996 Standard Specifications as amended by the 1998 Supplemental Specifications, Subsections 101.03, 105.04, 501.12, 512.03, 513.03, 519.04, 520.04 and 521.01 for Working Drawings

The specifications have been revised to eliminate unnecessary construction delays that are caused during the processing of working drawings. The revisions provide for an "Approval" and "Certification" process and under the "Certification" process, a conditional certification of "Certified as Noted". These concepts are detailed in BDC99PR-004 dated May 17, 2001 that revised Section 17.9 of the NJDOT Procedures Manual for the processing of working drawings. Therefore, the following revisions are incorporated in the Standard Input (SI98DOT2):

101.03 Terms.
THE DEFINITION OF WORKING DRAWINGS IS CHANGED TO:

WORKING DRAWINGS. Stress sheets, shop drawings, diagrams, illustrations, schedules, performance charts, brochures, erection plans, falsework plans, framework plans, cofferdam plans, bending diagrams for reinforcing steel, and any other supplementary plans or similar data which are prepared by the Contractor or any subcontractor, manufacturer, supplier, or distributor, and which the Contractor is required to submit to the Engineer for approval or certification.

105.04 Working Drawings.
THE ENTIRE TEXT OF THIS SUBSECTION IS CHANGED TO:

        The Contractor shall submit Working Drawings for those particular items of Work or methods of construction (whether permanent or temporary) for which there are no specific detailed drawings contained within the Contract Documents prior to performing such items of work or performing such methods of construction. Working Drawings submitted by the Contractor shall only detail particular work to be performed under the Contract Documents and shall not change the Plans or Specifications. A design change shall only be implemented in compliance with the Department procedure for review and approval of a change of plan. The Engineer will return, without further review, any and all working drawings found by the Engineer to be repetitious or duplicative of items of Work specified or detailed within the Contract Documents or found to constitute an apparent change of plan; under such circumstances the Contractor shall have no claim for any delays incurred by reason of such improper submittal.
        The Contractor shall review, approve, sign and submit all Working Drawings in orderly sequence so as not to delay the Work, or the work of any other contractor. The Contractor shall be deemed to represent by its act of submitting a Working Drawings for review and approval for final design of conceptual plans (as more fully stated below) or certification for fabrication of items of Work, that it has in fact verified all field measurements and catalog numbers and other criteria and has determined field construction criteria, materials, and other criteria and that the Contractor has checked and coordinated each submitted Working Drawing with the requirements of the Contract Documents and the Work.
        The provisions below, for the certification of Working Drawings, shall only apply to the fabrication of all items of Work. Those provisions shall not apply to the review and approval of the design for proprietary walls, noise barriers, temporary sheeting, sheeting left in place, temporary structures, cofferdams and precast concrete culverts or any other items where conceptual plans were included in the Contract Documents and the Contractor is required to complete the final design plans. The items of such work are subject to Department approval. The Contractor shall submit final design plans and calculations, signed and sealed by a Professional Engineer licensed in the State, to the Engineer for Department approval. The Engineer will cause review and resolution of all comments. Upon resolution and satisfaction of all comments, the designated Design Unit will make a recommendation as to approval directed to the Engineer by affixing a stamp indicating "RECOMMENDED FOR APPROVAL". The Engineer will review said recommendation for approval, and within the Engineer’s discretion approve the drawing where warranted by a signature and affixing a stamp indicating "APPROVAL BY THE ENGINEER". The work covered by such Working Drawings shall not begin or be fabricated until at least a facsimile signature of the Engineer’s approval is received by the Contractor. The carrying out of the Work or the ordering of those materials relating to submitted working drawings before approval by the Engineer is rendered in writing shall constitute a cause for rejection or non-approval by the Engineer of the submitted working drawing and/or a cause for the temporary suspension of the Work so affected, pursuant to Subsection 108.15.
        The Engineer, upon receipt of a submitted Working Drawings relating to fabrication only, will cause the working drawing to be reviewed with reasonable promptness but only for conformance with the design concept of the project, and with the details and criteria set forth in the Contract Documents. The designated design unit may either certify compliance, conditionally certify compliance with notation or comment or reject Working Drawings as submitted. It shall be within the sole discretion of the designated design unit whether or not a submitted Working Drawing warrants being "certified", "conditionally certified" or "not certified".
        A stamp, signed by the designated design unit, reflecting the determination rendered will be affixed to the submitted drawing. Certification of the submitted Working Drawings, without condition, by the designated design unit will be reflected by a stamp stating "CERTIFIED". Conditional certification by the designated design unit will be reflected by a stamp stating "CERTIFIED AS NOTED". Rejection or non-certification will be reflected by a stamp stating "REVISE AND RESUBMIT".
        Where submitted Working Drawings are not certified due to nonconformance with the Contract Documents, poor quality, or other stated problem or error, the submitted Working Drawings will be returned directly to the Contractor by the designated design unit for the project with a copy to the Resident Engineer. The Contractor shall make any and all required revisions, corrections, additions and changes to the Working Drawings and otherwise comply with the directions of the designated design unit and shall promptly re-submit to the Engineer appropriately revised Working Drawings along with the required number of copies. The Contractor shall direct specific attention to the Engineer in writing or on resubmitted Working Drawings to those revisions, corrections, changes or additions that were not requested or directed by the designated design unit on previous submissions. The above-described process shall apply to all re-submissions and revised Working Drawings. The carrying out of the Work or the ordering of those materials relating to submitted Working Drawings before certification or conditional certification is rendered by the designated design unit in writing shall constitute a cause for rejection or non-certification by the Engineer of the submitted Working Drawings and/or a cause for the temporary suspension of the Work so affected, pursuant to Subsection 108.15.
        Where the Working Drawings are either certified or conditionally certified, the designated design unit for the Project will return the Working Drawings directly to the Contractor with a copy to the Resident Engineer. Upon receiving certification or conditional certification from the designated design unit in the form of a signed stamp affixed to the submitted Working Drawings, the Contractor may then order material and carry out any work relating to a submitted Working Drawings; however, where conditional certification is granted by the designated design unit, as reflected by a signed stamp affixed to the submitted drawing stating "CERTIFIED AS NOTED", the Contractor, as a condition of certification, shall submit to the Engineer revised Working Drawings incorporating or satisfying the conditions of the certification as reflected in the designated design unit’s notes or comments within 30 days of receipt of the conditionally certified Working Drawings by the Contractor.
        Unless prior written approval of the Engineer has been given to the Contractor, the Contractor shall not make any deviations from the approved, certified or conditionally certified Working Drawings. Where the Contractor fails to abide by the Working Drawings as approved or certified or fails to abide by the conditions of a conditional certification, while performing that item of Work to which same applies, such failure shall constitute a cause for the temporary suspension of such work pursuant to Subsection 108.15.
        The designated design unit’s certification or conditional certification, or the Engineer’s approval of Working Drawings, does not relieve the Contractor of any responsibility or liability or modify such responsibility or liability that the Contractor may have under the Contract Documents or under law or equity arising out of or from the Working Drawings, for errors or omissions contained within the Working Drawings or for work carried out pursuant thereto. Also, the designated design unit’s certification or conditional certification or the Engineer’s approval of Working Drawings shall not be the basis of a claim by the Contractor against the State for indemnification, extra work, change in the character of the work or other similar cause of action. The designated design unit’s certification or conditional certification or the Engineer’s approval of a separate item of work is not to be construed as certification or approval of an assembly in which the item of work functions; the entire assembly must also be certified or conditionally certified by the designated design unit or approved by the Engineer.
        The design of all permanent and temporary structures shall conform to the current AASHTO Standard Specifications for Highway Bridges or, if directed by the Department, the design shall be based on the current AASHTO LRFD Bridge Design Specifications. Additionally, the provisions of the current NJDOT Bridges and Structures Design Manual shall be adhered to.
        Working Drawings shall be 594 by 841 millimeters (A1), which shall have 540 millimeter by 775 millimeter drawing area within the border, or 210 by 297 millimeters (A4). Seven copies shall be submitted to the designated design unit for review and a copy of the transmittal letter shall be sent to the Resident Engineer, except that for railroad carrying structures, four additional copies shall be submitted to the designated design unit. One additional copy each shall be submitted when an outside testing agency or an outside authority is involved in the Project. The above submittal procedure will simultaneously facilitate both certification and distribution.
        Each Working Drawing, shall be identified by a title block in the lower right-hand corner, containing the following minimum information:
