TC-4.01 WORKING DRAWINGS

(a) General. The Plans shall be supplemented by working drawings as necessary to adequately control the work. All authorized alterations affecting the requirements and information given on the working drawings shall be in writing to the Engineer. When reference is made to the working drawings, the interpretation shall be the working drawings as affected by all authorized alterations then in effect.
Working drawings shall show details of all structures, lines, grades, typical cross section of roadway, general cross sections, location, and designation of all units and elements.
The Contractor shall provide, at no additional cost to the Administration, all required working drawings and shall have them adequately checked, after which they shall be submitted to the Engineer for review. The Engineer may reject working drawings and return them for revisions, in which case the Contractor shall submit revised working drawings as required. No items involving the drawings shall be incorporated into the work until the Engineer has accepted the drawings for use; however, acceptance shall not relieve the Contractor of any responsibility in connection with them. All working drawings shall be furnished in duplicate for preliminary examination for projects prepared by the Administration and in triplicate for projects prepared by consultant engineering firms for the Administration. After the Engineer has accepted working drawings for use, the Contractor shall furnish additional copies as requested.
All working drawings shall be on sheets measuring 22 in. by 34 in. or 24 in. by 36 in. and shall have a standard title block at the lower right corner approximately 4 in. by 8 in. (2 in. for the revision column on the left side and the remaining 6 in. for the title) indicating the following information in the order named:


Name of Contractor (and subcontractor, if applicable)
Address of Contractor (and subcontractor, if applicable)
Sheet Title (Reinforcement Details, etc.)
Name of Structure
Crossing
For (Maryland Department of Transportation State Highway Administration)
By (Indicate name of Contractor's official or engineer, or other parties authorized to sign official documents.)


List all Administration Contract numbers, complete Federal Aid number, if any, and the date the drawing was completed. The left portion of the title block shall be headed "Revisions" and the space used as needed.
Working drawings for standard scuppers are not required. A sketch or statement specifying the type and number of standard scuppers required and the length of the downspout is acceptable.
The working drawings shall be submitted for review to the applicable Director's Office. A copy of the transmittal letter shall be forwarded to the appropriate District Engineer. The number of working drawings to be furnished shall be as specified above and addressed to one of the following:

(b) Working Drawings for Falsework Systems. Falsework systems (design, plans, and construction) shall be the responsibility of the Contractor, including submitting and obtaining written acceptance of the design and plans by the Engineer before erection.
The Contractor shall utilize a professional engineer (P.E.) registered in the State of Maryland who has at least five years experience in falsework design for bridge construction and repair. The falsework design calculations and plans shall be signed by the P.E. and bear the seal of the P.E. The submittal of the design and falsework plans shall include the P.E.'s resume showing evidence of the required experience.
The P.E.’s plans and design calculations shall evaluate and qualify all products and components including manufactured products and proprietary items for their intended service. Acceptance by the Engineer of falsework systems shall not in any way relieve the Contractor of the responsibility for the safety and adequacy of the design and construction for the falsework systems and operations, including all components.
Every structure in the construction Contract will require a separate falsework design analysis, separate plans, and design submittal as set forth above. This applies even though structures may appear to be identical.
Each falsework system shall be designed to support all vertical and horizontal loading with enough redundancy to prevent progressive failure. Vertical loading, differential settlement forces, live load where applicable, and all horizontal, lateral, and longitudinal forces shall be taken into account. Unbalanced temporary loading caused by placement sequence shall also be provided for in the design. Adequate diagonal bracing in all planes shall be employed.
All falsework systems (designs, plans, and construction) shall provide for adequate foundations with bearings below the frost line or on rock or on piling, and for possible settlement. If additional subsurface data is necessary, it shall be obtained and analyzed for proper design of the plans and performance of construction.
Falsework designs and plans shall include protection against impact from uncontrolled highway vehicles, accidental collision of a crane boom or other construction equipment and vehicles, traffic vibration, flood waters, high winds, and any other envisioned contingent situations.

TC-4.02 FAILURE TO MAINTAIN PROJECT

GP-5.12 (Failure to Maintain Entire Project) is not applicable to Administration Contracts. The provisions of this TC shall apply.
If the Contractor, at any time, fails to respond to the provisions of GP-5.11 (Maintenance of Work During Construction), the procurement officer will immediately notify the Contractor to comply with the required maintenance provisions. If corrective actions do not begin within four hours after receipt of the notice, the procurement officer may:
(a) Notify the contractor to suspend all other work until the unsatisfactory maintenance is corrected, or
(b) Proceed at anytime with adequate forces and equipment to maintain the project. The entire cost of this maintenance will be deducted from monies due the Contractor on the next progress payment.

TC-4.03 USE AND POSSESSION PRIOR TO COMPLETION

In addition to the provisions of GP-7.15 (Use and Possession Prior to Completion) the following will apply on Administration Contracts:
Upon written authorization of the procurement officer, the Contractor may be relieved of maintenance during the time the Administration has taken possession. Any portion of the work that may be disturbed or damaged shall be restored at respective Contract prices for items involved, or on the basis of a predetermined arrangement entered into by the Contractor and procurement officer before the performance of the restoration work.


TC-4.04 SUSPENSION OF WORK

In addition to the provisions of GP-8.07 (Suspension of Work), the following shall apply on Administration Contracts.
The Engineer will have the authority to suspend the work wholly or in part due to the failure of the Contractor to correct conditions unsafe for the workers or the general public; for failure to carry out the requirements of the Contract Documents, or as directed in conformance with the Contract Documents for conditions considered unsuitable for the prosecution of the work.


TC-4.05 DISPUTE MEDIATION

When a dispute arises out of or relates to the Contract or breach thereof, and if the dispute cannot be settled through negotiation or the partnering issue resolution process, either party may first elect to try in good faith to settle the dispute by nonbinding mediation administered by a mutually agreed upon qualified mediator before proceeding with other dispute resolution procedures including litigation.
