the implementation, operation, and inspection of traffic control on the referenced project are trained, or will be trained prior to beginning work, appropriate to the decisions each individual is required to make in accordance with 23 CFR 630 Subpart J”. This wording shall be followed by the signature of an authorized representative of the Contractor. Employees shall receive periodic training updates that reflect changing industry practices. The Contractor shall maintain records of the training. The records shall include dates of training, name of instructor, name of attendee, length of course, and topics covered. The records shall be available for auditing by the Engineer.

Special construction signs shall consist of signs which require special fabricated sign panels or special mounting requirements; such signs will be designated as "Special" on the construction plans.

Pilot car operation and associated flagging shall be performed as described in the MUTCD. Flagmen and flagging devices are considered a necessary requirement of the pilot car operation and no direct payment will be made for such.

The Contractor shall assume full responsibility for the continuous and expeditious maintenance of all construction warning signs, barricades and other traffic control devices. Maintenance shall include, but shall not be limited to, replacement of sign panels, barricades and other devices which, in the opinion of the Engineer, are damaged or deteriorated beyond effective use, replacement of broken supports, plumbing of leaning signs, cleaning of dirty signs, barricades and other devices, repair of defaced signs, replacement of stolen items, etc. All items used for traffic control shall be generally maintained in its original placement condition and such maintenance will be considered a part of the original installation cost. Failure to maintain all traffic control devices in such manner as to provide adequate continuous safety to the public will be cause for action by the Engineer as noted in the last paragraph of Item 740.03(a)5.

Reference is made to Section 107 of the Specifications which covers the legal responsibilities of the Contractor to the traveling public. Although the Department will be designating and directing the placement of certain traffic control devices, the Contractor is not relieved of his responsibility to continuously review and maintain all traffic handling measures and ensure himself that adequate provisions have been made for the safety of the public and workmen. Construction signs and other traffic control devices specified by plan details are considered the necessary requirements for satisfactory traffic control. This does not preclude the Engineer from ordering, or the Contractor from requesting for approval, additional signs or traffic control devices to safely handle unforeseen traffic situations, in which case they would be paid for. The Contractor may, with the approval of the Engineer, furnish additional traffic control devices, at no cost to the Department, to protect his work and/or workmen.

740.04Method of Measurement

The various items used in the handling of traffic through construction zones will be measured for payment as follows: Construction Signs and Special Construction Signs which are specified by plan details or ordered by the Engineer and approved for use will be measured in square feet {square meters} computed from measurements of the actual sign panel installed (no deductions will be made for corner radii). The sign supports and mounting hardware are considered incidental to the use of these sign units; hence no separate measurement or payment will be made for the supports and hardware. Measurement for payment under the Item of Special Construction Signs will only be made on signs designated as "Special" by plan details or ordered as "Special" by the Engineer. Drums will be measured individually for the number ordered and furnished. Cones will be measured per each and shall be 36 inches {900 mm} high with a ballasted base. Cones of smaller height may be used for operations such as pavement striping and marking, but no direct payment will be made. Barricades will be measured individually for the type designated and furnished. TRAFFIC CONTROL DEVICES FOR CONSTRUCTION WORK ZONES 645

Delineators will be measured per each which includes a 3 inches {75 mm} in diameter reflector of designated color, mounted on a #2 {3 kg/m} steel post or equivalent aluminum post as specified by Part VI of the MUTCD. Warning lights will be measured per each for the type furnished. Vertical panels will be measured per each installation for the number of installations ordered and furnished, which shall include the panel, or panels, post, and hardware. A single-sided installation shall be an installation requiring a panel on only one side of the post. A double-sided installation shall be an installation requiring a panel on each side of the post. The construction plans may contain traffic handling schemes detailing the signs, barricades and other traffic control devices to be installed at certain locations or in some cases for the entire project. If specified on these traffic handling schemes, and a lump sum pay item is provided, payment shall be made on a Lump Sum basis for all signs and devices detailed on these schemes. Signs, barricades, and other traffic control devices included in this Lump Sum measurement shall meet all requirements as outlined in this Section. Other traffic control items such as traffic control stripes, legends and markings, portable concrete barriers, sequential chevron and arrow boards and pavement markers when so required will be measured and paid for under the appropriate Section for such provided in the Specifications. Measurement of Item 740-O, Pilot Car, will be the actual number of units (per Each) ordered and accepted. No direct measurement or payment will be made for a pilot car unless it is listed in the pay items of the contract. Portable Rumble Strips will be measured per lump sum.

740.05Basis of Payment

Payment for Construction Signs and Special Construction Signs measured as noted above will be paid for at the contract unit price bid which shall be full compensation for fabrication of sign panel with proper sheeting and legend, furnishing and erecting on proper supports, furnishing all mounting hardware, covering when not in use, handling and maintaining until project completion. Payment for drums, barricades, cones, delineators, warning lights, and vertical panels, measured as noted above, will be paid for at the contract unit price bid which shall be full compensation for fabrication, erection at designated locations whenever required, , handling and maintenance until project completion. Payment for cones shall include ballasts. Item 740-O, Pilot Car, measured as noted above will be paid for at the contract unit price bid which shall be full compensation for furnishing and operating the pilot car, for furnishing the pilot car driver and flaggers, for all equipment and materials necessary to complete the work. Item 740-P, Portable Rumble Strips, measured as noted above will be paid for at the contract unit price bid which shall be full compensation for fabrication, for installation at designated locations whenever required, and for handling and maintenance until project completion. Payment for Items 740-B - M and 740-P will further include all costs in relocating, removing and returning these Items to the project when required to provide a complete traffic control system throughout the life of the project. No payment will be made beyond the maximum quantity of signs, barricades or other traffic control devices installed at any one time except when alternate sign panels are required for proper handling of the traffic, in such case both alternate panels will be measured for payment. The Lump Sum payment for traffic control devices specified by plan details shall be full compensation for furnishing all materials, power sources and mounting hardware, erecting, handling, relocating signs and devices within the indicated "Traffic Handling Scheme" and maintaining all traffic control devices until project completion. If traffic control devices are deleted from the traffic handling scheme that is to be paid on a lump sum basis, deductions for the items deleted will be made from the lump sum cost in the amount of the contract unit prices bid for the quantity of individual traffic control items so deleted. Traffic control items which are added to the lump sum traffic handling scheme will be paid for at the contract unit price for the item added. A lump sum payment will be considered as full compensation for "traffic handling scheme". Once construction signs or other warning devices are no longer needed within the designated limits of the lump sum "traffic handling scheme", they may be used in other areas of traffic control and payment will be made under the appropriate pay item. PORTABLE SEQUENTIAL ARROW AND CHEVRON SIGN UNIT 646

Unless otherwise designated on the construction plans, all signs, barricades, and other traffic control devices covered by this Section shall become the property of the Contractor at the completion of the project. The salvage value for these items shall be reflected in the contract unit prices bid. No payment will be made for stored materials under this Section unless the material in storage was either manufactured or purchased new for specific use on the project. No payment will be made for devices installed solely for the protection of the Contractor's work and which serve no useful purpose in protecting the safety of the public or workmen such as traffic cones for paint protection, devices installed to protect fresh concrete presenting no hazard, etc. The Contractor will be expected to submit a balanced bid for all traffic control items. The submission of unbalanced bid prices may result in loss of contract award.
